The Teenage Girl as Consumer and CommunicatorHavas PR
Euro RSCG Worldwide PR’s white paper analyzes data from a survey the agency commissioned of 100 girls between the ages of 13 and 18 about their spending and communications habits. The research reveals that the teenage girl contradicts almost all cultural stereotypes in those areas. But the core finding of the white paper is more sociological than statistical. Tearing down another false platitude about teenage girls, the paper proves that a sense of intimacy with a select group of friends and family drives almost all their social interaction—including shopping, which the study characterizes as a core social activity for teenage girls. The findings are helping to launch a new Euro PR initiative. Eventually focusing on teen boys and girls, the first phase is called The Sisterhood.

Chapter 10. ScenariosI have always been a big fan of learninEstelaJeffery653
Chapter 10. Scenarios
I have always been a big fan of learning from the mistakes of others. In the computer security realm, by carefully noting the errors of other people, we can gain major insights into how attackers take advantage of these mistakes and undermine computers and networks. Most important, we can also make sure that we apply the appropriate procedural and technological defenses on our own systems so that a similar fate doesn't befall us. I also enjoy seeing concrete scenarios and case studies, instead of abstract ideas. By watching an attack in action, I can get a good feel for how it works and how to apply the necessary defenses in my own environment.
With those ideas in mind, this chapter covers three malware attack scenarios. These case studies explore ideas we've covered in chapters throughout the book, using a variety of different types of malware, including backdoors, worms, and kernel-mode RootKits. Each of these scenarios is based on common mistakes made by computer users, system administrators, and security personnel. The technical details of these cases are all based on fact, representing a synthesis of attacks I've seen in various incidents my colleagues and I have handled. To disguise the corporations, government agencies, and educational institutions originally plagued in these attacks, I've adapted the scenarios to certain familiar themes, and have changed the names to protect both the innocent and the guilty. Any similarities to real persons, living or deceased, are purely coincidental.
As we progress through each scenario, we'll discuss the mistakes made by the victim users and administrators, so we can learn lessons from their errors. We'll also illustrate the advance of malware through a target network environment with numerous figures. In these pictures, when a malware specimen conquers a given machine, we'll show the fact pictorially using the icon from Figure 10.1.
Figure 10.1. A machine conquered by an attacker's malware.
Now, go grab yourself a bag of fresh, buttery popcorn and an extra-large soda. Draw the shades, dim the lights, and sit back in your easy chair, as we take a look at three different horror-themed scenarios:
A Fly in the Ointment.
Invasion of the Kernel Snatchers.
Silence of the Worms.
In our first scenario, we'll look at how some common mistakes by an end user can result in a major malware infection.

The document discusses the Media Access Control (MAC) address, which is a unique identifier assigned to network interfaces for identification. MAC addresses are permanent and work at the data link layer, unlike IP addresses which can change and work at the network layer. MAC address spoofing involves changing the MAC address to hide a device's identity or bypass access control lists. Intrusion detection systems are also discussed as important tools to detect attacks on networks.

DoS (Denial of Service) Attack Tutorial Ping of Death, DDOS Wha.docxmadlynplamondon
DoS (Denial of Service) Attack Tutorial: Ping of Death, DDOS
What is DoS Attack?
DOS is an attack used to deny legitimate users access to a resource such as accessing a website, network, emails, etc. or making it extremely slow. DoS is the acronym for Denial of Service. This type of attack is usually implemented by hitting the target resource such as a web server with too many requests at the same time. This results in the server failing to respond to all the requests. The effect of this can either be crashing the servers or slowing them down.
Cutting off some business from the internet can lead to significant loss of business or money. The internet and computer networks power a lot of businesses. Some organizations such as payment gateways, e-commerce sites entirely depend on the internet to do business.
In this tutorial, we will introduce you to what denial of service attack is, how it is performed and how you can protect against such attacks.
Topics covered in this tutorial
· Types of Dos Attacks
· How DoS attacks work
· DoS attack tools
· DoS Protection: Prevent an attack
· Hacking Activity: Ping of Death
· Hacking Activity: Launch a DOS attack
Types of Dos Attacks
There are two types of Dos attacks namely;
· DoS– this type of attack is performed by a single host
· Distributed DoS– this type of attack is performed by a number of compromised machines that all target the same victim. It floods the network with data packets.
How DoS attacks work
Let’s look at how DoS attacks are performed and the techniques used. We will look at five common types of attacks.
Ping of Death
The ping command is usually used to test the availability of a network resource. It works by sending small data packets to the network resource. The ping of death takes advantage of this and sends data packets above the maximum limit (65,536 bytes) that TCP/IP allows. TCP/IP fragmentation breaks the packets into small chunks that are sent to the server. Since the sent data packages are larger than what the server can handle, the server can freeze, reboot, or crash.
Smurf
This type of attack uses large amounts of Internet Control Message Protocol (ICMP) ping traffic target at an Internet Broadcast Address. The reply IP address is spoofed to that of the intended victim. All the replies are sent to the victim instead of the IP used for the pings. Since a single Internet Broadcast Address can support a maximum of 255 hosts, a smurf attack amplifies a single ping 255 times. The effect of this is slowing down the network to a point where it is impossible to use it.
Buffer overflow
A buffer is a temporal storage location in RAM that is used to hold data so that the CPU can manipulate it before writing it back to the disc. Buffers have a size limit. This type of attack loads the buffer with more data that it can hold. This causes the buffer to overflow and corrupt the data it holds. An example of a buffer overflow is sending emails with file names that have 256 characters ...
This document summarizes techniques for gaining unauthorized access to computer systems, specifically a VAX/VMS system. It describes using control commands like control-T to view login procedures and discover privileges.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
2. Introduction The internet is ever growing and you and I are truly pebbles in a vast ocean of information. They say what you don’t know can’t hurt you. When it comes to the Internet believe me its quite the opposite. On the Internet there a millions and millions of computer users logging on and off on a daily basis. Information is transferred from one point to another in a heartbeat. Amongst those millions upon millions of users, there’s you.As humble a user you may be of the Internet, you are pitted against the sharks of the information super highway daily. Problem with that is the stealth by which it happens. Currently about 30-40% of all users are aware of the happenings on their computer. The others simply either don’t care or don’t have the proper “know how” to recognize if their system is under attack and or being used. You can never have enough information. likely you are to fall prey to the sharks of the Internet.Information is power and the more informed you as a user become the lesslikely you are to fall prey to the sharks of the Internet.
3.
4. SYSTEM INTRUSION IN 15 SECONDS System intrusion in 15 seconds, that’s right it can be done. If you possess certain security flaws your system can be broken into in less that 15 seconds. To begin this chapter I’d like you to do the following. Connect to the Internet using your dial up account if you are on dial up. If you are on dedicated service like High Speed connections (ie, Cable and DSL) then just proceed with the steps below.Click Start, Go to Run, Click Run ,Type Winipcfg, Hit the Enter Key.This should bring up a window. What you should see under IP address is 207.175.1.1 (The number will be different.)Which is your IP Address . If you use Dial Up Internet Access then you will find your IP address under PPP adapter. If you have dedicated access you will find your IP address under another adapter name like (PCI Busmaster, SMC Adapter, etc.) You can see a list by clicking on the down arrow. Once you have the IP address write it down, then open the Dos Prompt .
5.
6. This is how a “hacker” would check to see if you have “file and printer sharing” turned on. If he/she becomes aware of the fact that you do have “file and printer sharing” turned on then they would proceed to attempt to gain access to your system. I’ll show you now how that information can be used to gain access to your system. A potential hacker would do a scan on a range of IP address for systems with “File and Printer Sharing” turned on. Once they have encountered a system with sharing turned on the next step would be to find out what is being shared. This is how: Net view <207.175.1.1> Our potential hacker would then get a response that looks like this. Shared resources at 207.175.1.1 Sharename Type Comment MY DOCUMENTS Disk TEMP Disk This shows the hacker that his potential victim has their My Documents Folder shared and their Temp directory shared. For the hacker to then get access to those folders his next command will be. Net use x: <207.175.1.1>emp If all goes well for the hacker, he/she will then get a response of At this point the hacker now has access to the TEMP directory of his victim.This is called a Netbios attack .
7. If you are running a home network then the chances are you have file and printer sharing turned on. This may not be the case for many users but I’m sure there is quite a number of users who probably do. If you are sharing resources then password protect the directories .Netbios is one of the older forms of system attacks that occur. It is usually overlooked because most systems are protected against it. Recently there has been an increase of Netbios Attacks . DOS Attack : This is used to crash the victim’s computer. In this attack the attacker sends large size (1024 Bytes) dummy packets to the victim. Consequently the computer crashes due to heavy data inflow or it slows down the computer and kills the internet connection. The ping in DOS Prompt is used to execute the attack. The command for DOS Attack is c:>ing -L (Amount of junk to be send recommended=1024) -T <ip address>
8. THE TROJAN “HORSE” Trojan’s are probably the most compromising of all types of attacks. Trojans are being released by the hundreds every week, each more cleverly designed that the other. We all know the story of the Trojan horse probably the greatest strategic move ever made.In my studies I have found that Trojans are primarily responsible for almost all Windows Based machines being compromised.For those of you who do not know what Trojans are I’ll briefly explain. Trojans are small programs that effectively give “hackers” remote control over your entire Computer.Some common features with Trojans are as follows:Open your CD-Rom drive,Capture a screenshot of your computer,Record your key strokes and send them to the “Hacker”,Full Access to all your drives and files,to use your computer as a bridge to do other hacking related activities,Disable your keyboard,Disable your mouse…and more! Let’s take a closer look at a couple of more popular Trojans: Netbus,SubSeven,BackGate,Senna Spy FTP server etc The Netbus Trojan has two parts to it as almost all Trojans do.There is a Client and a Server. The server is the file that would have to get installed on your system in order to have your system compromised.
9. The Hack Objective : Getting the potential victim to install the server onto his/her system. Method 1 Send the server file (for explanation purposes we’ll call the file netbusserver.exe) to you via E-Mail. This was how it was originally done. The hacker would claim the file to be a game of some sort. When you then double click on the file, the result is nothing. You don’t see anything. (Very Suspicious) Note: (How many times have you double clicked on a file someone has sent you and it apparently did nothing) At this point what has happened is the server has now been installed on your system. All the “hacker” has to do is use the Netbus Client to connect to your system and everything you have on your system is now accessible to this “hacker.” With increasing awareness of the use of Trojans, “hackers” became smarter, hence method 2.
10. Method 2 Objective: Getting you to install the server on your system. Let’s see, how many of you receive games from friends? Games like hit gates in the face with a pie. Perhaps the game shoot Saddam? There are lots of funny little files like that. Now I’ll show you how someone intent on getting access to your computer can use that against you. There are utility programs available that can combine the (“server” (a.k.a. Trojan)) file with a legitimate “executable file.” (An executable file is any file ending in .exe). It will then output another (.exe) file of some kind. Think of this process as mixing poison in a drink. For Example: Tomato Juice + Poison = Something Now the result is not really Tomato Juice anymore but you can call it whatever you want. Same procedure goes for combining the Trojan with another file. For Example: The “Hacker” in question would do this: (for demonstration purposes we’ll use a chess game) Name: chess.exe (name of file that starts the chess game) Trojan: netbusserver.exe (The Trojan)
11. (Again for explanation purposes we’ll call it that). The joiner utility will combine the two files together and output 1 executable file called: <insert name here>.exe This file can then be renamed back to chess.exe. It’s not exactly the same Chess Game. It’s like the Tomato Juice, it’s just slightly different. The difference in these files will be noticed in their size. The original file: chess.exe size: 50,000 bytes The new file (with Trojan): chess.exe size: 65,000 bytes (Note: These numbers and figures are just for explanation purposes only) The process of joining the two files, takes about 10 seconds to get done. Now the “hacker” has a new chess file to send out with the Trojan in it. When we open the chess program it starts like normal. No more suspicion because the file did something. The only difference is while the chess program starts the Trojan also gets installed on your system.Now you receive an email with the attachment except in the format of chess.exe. The unsuspecting will execute the file and see a chess game Meanwhile in the background the “Trojan” gets silently installed on your computer. If that’s not scary enough, after the Trojan installs itself on your computer, it will then send a message from your computer to the hacker telling him the following information
12. Username: (A name they call you) IP Address: (Your IP address) Online: (Your victim is online) So it doesn’t matter if you are on dial up. The potential hacker will automatically be notified when you log on to your computer. You’re probably asking yourself “how likely is it that this has happened to me?” Well think about this. Take into consideration the second chapter of this manual. Used in conjunction with the above mentioned methods can make for a deadly combination.These methods are just but a few ways that “hackers” can gain access to your machine. Listed below are some other ways they can get the infected file to you. News Groups: By posting articles in newsgroups with file attachments like (mypic.exe) in adult newsgroups are almost guaranteed to have someone fall victim. Don’t be fooled though, as these folks will post these files to any newsgroups. Grapevine : Unfortunately there is no way to control this effect. You receive the file from a friend who received it from a friend etc. Email : The most widely used delivery method. It can be sent as an attachment in an email addressed to you.
13. Unsafe Web sites : Web sites that are not “above the table” so to speak. Files downloaded from such places should always be accepted with high suspicion. IRC : On IRC servers sometimes when you join a channel you will automatically get sent a file like “mypic.exe” or “imp.exe” or mypic.jpg.vbs something to that effect. Usually you’ll find wannabe’s are at fault for this. Chat Sites : Chat sites are probably one of the primary places that this sort of activity takes place. The sad part to that is 80% are not aware of it. As you can see there are many different ways to deliver that file to you as a user. By informing you of these methods I hope I have made you more aware of the potential dangers around you.
14. WHO ARE HACKERS? I feel it is necessary to clarify the term hacker. Perhaps your definition of a hacker has been influenced and tainted over the years. There have been various computer related activities attributed to the term “hacker”, but were greatly misunderstood. Unfortunately for the people who are truly defined within the underground tech world as a “hacker” this is an insult to them. There are various types of “hackers”, each with their own agenda. Anarchist Hackers These are the individuals who you should be weary of. Their sole intent on system infiltration is to cause damage or use information to create havoc. They are primarily the individuals who are responsible for the majority of system attacks against home users. They are more likely to be interested in what lies on another person’s machine for example yours. Mostly you’ll find that these individuals have slightly above computer skill level and consider themselves hackers. They glorify themselves on the accomplishments of others.
15. Their idea of classing themselves as a hacker is that of acquire programs and utilities readily available on the net, use these programs with no real knowledge of how these applications work and if they manage to “break” into someone’s system class themselves as a hacker. These individuals are called “Kiddie Hackers.” They use these programs given to them in a malicious fashion on anyone they can infect. They have no real purpose to what they are doing except the fact of saying “Yeah! I broke into <insert name here> computer!” It gives them bragging rights to their friends. If there is any damage to occur in a system being broken into these individuals will accomplish it.These individuals are usually high school students. They brag about their accomplishments to their friends and try to build an image of being hackers. Hackers A hacker by definition believes in access to free information. They are usually very intelligent people who could care very little about what you have on your system. Their thrill comes from system infiltration for information reasons. Hackers unlike “ crackers and anarchist” know being able to break system security doesn’t make you a hacker any more than adding 2+2 makes you a mathematician. Unfortunately, many journalists and writers have been fooled into using the word ‘hacker.”
16. They have attributed any computer related illegal activities to the term “ hacker.”Real hackers target mainly government institution. They believe important information can be found within government institutions. To them the risk is worth it. The higher the security the better the challenge. The better the challenge the better they need to be. Who’s the best keyboard cowboy? So to speak! These individuals come in a variety of age classes. They range from High School students to University Grads. They are quite adept at programming and are smart enough to stay out of the spotlight.They don’t particularly care about bragging about their accomplishments as it exposes them to suspicion. They prefer to work from behind the scenes and preserve their anonymity. Not all hackers are loners, often you’ll find they have a very tight circle of associates, but still there is a level of anonymity between them. An associate of mine once said to me “if they say they are a hacker, then they’re not!” Crackers For definition purposes I have included this term. This is primarily the term given to individuals who are skilled at the art of bypassing software copyright protection . They are usually highly skilled in programming languages. They both fight security of some kind,but they are completely different “animals.” But….. .”Know your enemy and know yourself and you will always be victorious…..”
17. TOOLS OF THE TRADE That is a carpenter without a hammer? “Hackers” require tools in order to attempt to compromise a systems security. Some tools are readily available and some are actually written by other hackers, with the sole intent of being used for system break-ins. Some “hackers’ use a little ingenuity with their attacks and don’t necessarily rely on any particular tool. To better understand the means by which “hackers” compromise system security I feel it important to understand what tools they use. This will give you as a user insight as to what exactly they look for and how they obtain this information. In this section, I also explain how these tools are used in conjunction with each other. Port Scanners What is a port scanner? A port scanner is a handy tool that scans a computer looking for active ports. With this utility, a potential “hacker” can figure out what services are available on a targeted computer from the responses the port scanner receives. Take a look at the list below for reference.
18. Starting Scan. Target Host: www.yourcompany.com TCP Port :7 ( echo ),TCP Port :9 ( discard ),TCP Port :13 ( daytime ), TCP Port :19 ( chargen ),TCP Port :21 ( ftp ),TCP Port :23 ( telnet ), TCP Port :25 ( smtp ),TCP Port :37 ( time ),TCP Port :53 ( domain ), TCP Port :79 ( finger ),TCP Port :80 ( www ),TCP Port :110 ( pop ), TCP Port :111 ( sunrpc ),Finished. Scanning for open ports is done in two ways. The first is to scan a single IP address for open ports. The second is to scan a range of IP address to find open ports. Try to think about this like calling a single phone-number of say 555-4321 and asking for every extension available. In relation to scanning, the phone-number is equivalent to the IP address and the extensions to open ports. Scanning a range of IP address is like calling every number between 555-0000 to 555-9999 and asking for every extension available at every number. Trojans - Trojans are definitely one of the tools that “hackers” use. There are hundreds of Trojans. To list them all would make this manual extremely long. For definition purposes we’ll focus on a couple. Sub Seven The Sub Seven Trojan has many features and capabilities. It is in my opinion by far the most advance Trojan I have seen
19. Take a look at some of the features of Sub Seven. address book,WWP Pager Retriever,UIN2IP,remote IP scanner,host lookup,get Windows CD-KEY,update victim from URL,ICQ takeover, FTP root folder,retrieve dial-up passwords along with phone numbers and usernames , port redirect,IRC bot. for a list of commands, File Manager bookmarks, make folder, delete folder [empty or full],process manager,text 2 speech,Restart server,Aol Instant Messenger Spy,Yahoo Messenger Spy, Microsoft Messenger Spy,Retrieve list of ICQ uins and passwords,Retrieve list of AIM users and passwords,App Redirect,Edit file,Perform clicks on victim's desktop,Set/Change Screen Saver settings [Scrolling Marquee],Restart Windows ,Ping server,Compress/Decompress files before and after transfers,The Matrix,Ultra Fast IP scanner,IP Tool [Resolve Host names/Ping IP addresses], Get victim's home info [not possibleonallservers]:, Address,Bussinessname,City,Company,Country,Customer type,E-Mail,Real name,State,City code,Country code,Local Phone,Zip code,And more… I think you get the picture of just exactly what that Trojan is capable of.
21. Netbus: NetBus is an older Trojan however nonetheless is still used. It consists of a server and a client-part. The server- part is the program which must be running on your computer. This should give you an idea of what Netbus is capable of. Netbus Features: Open/close the CD-ROM once or in intervals (specified in seconds),Show optional image. If no full path of the image is given it will look for it in the Patch-directory. The supported image-formats is BMP and JPG .,Swap mouse buttons – the right mouse button gets the left mouse button’s functions and vice versa.,Start optional application.,Play optional sound-file. If no full path of the sound-file is given it will look for it in the Patch-directory. The supported sound-format is WAV,Point the mouse to optional coordinates. You can even navigate the mouse on the target computer with your own,Show a message dialog on the screen. The answer is always sent back to you, Shutdown the system, logoff the user etc,Go to an optional URL within the default web-browser,Send keystrokes to the active application on the target computer. The text in the field ”Message/text” will be inserted in the application that has focus. (”|” represents enter) Listen for keystrokes and send them back to you . Get a screendump (should not be used over slow connections),Return information about the target computer, Upload any file from you to the target computer .
22. With this feature it will be possible to remotely update Patch with a new version increase and decrease the sound-volume,Record sounds that the microphone catch. The sound is sent back to you,Make click sounds every time a key is pressed,Download and deletion of any file from the target. You choose which file you wish to download/delete in a view that represents the harddisks on the target,Keys (letters) on the keyboard can be disabled,Password-protection management,Show, kill and focus windows on the system,Redirect data on a specified TCP-port to another host and port,Redirect console applications I/O to a specified TCP-port(telnet the host at the specified port to interact with theapplication),Configure the server-exe with options like TCP-port and mail notification.This is what the Netbus client looks like.

25. The screen shot would look like this. From that screen shot they can tell what site you are at (in which case it would be your bank). From there it’s just a matter of logging into your bank account and doing whatever they want. As you can see although you are on a secure web site, it still doesn’t protect your information once your computer is compromised.
26. Perhaps there are some of you who do not use online banking. Perhaps you use another program for managing your finances. There is a variety of programs out there available for financial purposes. Problem is that once a “hacker” has access to your system, they have access to those files. They can copy the files from your computer to theirs and browse through them at their leisure. Email Simply put all emails sent to you are accessible to a “hacker” once your system has been compromised. They can read them and possibly check your mail before you do. Pictures If you have pictures of yourself or family members on your system, they are also available to the “hacker.” I don’t think I need to explain the danger here. Not only has the individual compromised your computer system, they also know what you look like. Resume This may not sound like a priority file for a “hacker” but stay with me for a second. How many of you have resumes typed up on your computers? I’m sure a lot of you do. If a “hacker” were to download your resume they now have access to: Name: Address: Phone:
27.
28. The Trojan records the sounds in a room via your microphone and then sends the file back to the “hacker.” The hacker then plays the file back and can hear any sounds recorded in the room. Add to that since the recording is a file they can play it back whenever they want to who ever they want. By the same method they access your Web Cam effectively getting both a video and audio feed from your house of what is currently going on in that room. That sounds impossible, but I can assure you it is not. I don’t think I need to tell you what type of security hazard this represents to you and your family. By now you are probably worried of the possible vulnerabilities of your computer. In the next topic we will discuss how to protect your self.
29. HOW TO PROTECT YOURSELF There is a saying that goes “Prevention is better than cure.” After reading this manual hopefully you are looking for ways to protect your privacy. Take it back from those who may invade it. The individuals who are responsible for these attacks will always prey off those who do not take an interest in defending their privacy.“Give a man a fish and he’ll eat for the day. Teach a man how to fish and he’ll never starve.”By showing you steps and procedures you can use to protect your system from being hacked, you’ll quickly regain your sense of security. FIREWALLS A firewall in layman terms is essentially a program which filters network data to decide whether or not to forward them to their destination or to deny it . These programs will generally protect you from inbound “net attacks.” This means unauthorized network request from foreign computers will be blocked. Few good firewalls are: Black Ice Defender Lockdown 2000
30. Anti Virus Software This is also another piece of software you should by all means have on your system. We all know it’s a necessity however we are all guilty of not using them. There are numerous anti-virus software out there. Norton Antivirus and MacAfee are two of the more common ones. Its recommended that we should use 1 virus scanner and both firewalls.The reason is I find Black Ice Defender blocks incoming attacks and any system changes that occur on your system Lockdown catches. TIPS & TRICKS I feel it necessary for you to pay particular attention to this section. The above programs will function and do their job, but that’s only half the battle. There are certain precautions you need to take as a user to ensure your system remains a “fortress.” Tip #1: For Dial Up users : If you are a dial up user then you use a modem either internal or external kind to get online. If you have an external modem then this tip is easy.
31. If you look at the modem you’ll see lights on the front of it. When you’re doing anything on the net you’ll notice lights blinking that indicate that you are Sending Data, and Receiving Data. Depending on how often the lights blink and how fast they blink gives a rough idea of how much activity is going on between your computer and the net i.e. the amount of data transfer. For Example : If you have your email program open and you are just sitting there reading your mail, you may notice that every 15 sometimes 20mins that the lights will blink back and forth. indicating it’s sending and receiving data. This is normal because chances are you have your email program configured to check your mail every 20mins. If by chance you notice the lights on your modem is blinking consistently for let’s say a period of 2mins non stop be extremely suspicious. If you have an internal modem, you will not be able to see the lights on your modem, instead you can rely on the two TV looking icons at the bottom right corner of your screen near the clock. Any data being sent and received will be noticed by the blinking of the lights rapidly.
32.
33. You’ll see a variety of listings like the above. It will give you the Protocol being used, the local address (your computer) and what port on your computer the “Foreign Address” is being connected to and the (State) of which the (Foreign Address) is. For example if it is (Established) then that means whatever the foreign address says is currently connected to your machine. Protecting Shared Resources For those of you who have internal networks between two computers probably have a shared resource of some kind. Earlier in this manual I showed you how to find what is being shared. Now we will go to the Sharing Properties . This is where you can either share this folder or turn it off. If you wish to turn off the sharing you would select (Not Shared). If you must share folder then make it a read only folder . This will make the folder read only, that means no one can delete anything from those folders if they were to break into your system using a “NetBIOS” attack. The next step is to password protect the directory. My personal suggestion is to set any directory you are sharing to (Read Only) and password protect it. This is only if you must share resources. Disabling File and Printer Sharing For those of you who do not have a home network going you should disable file and printer sharing. There’s no reason to have this feature turned on.
34. EVERY SYSTEMS GREATEST FLAW To every computer system there is always this one system flaw. It does not matter how powerful a system you have, how many different firewall programs you run or how many virus scanners you have. In the end you are your systems worst enemy. All “hackers” know this, make no mistake about that. Thankfully not very many have the stamina necessary for a form of hacking called “Social Engineering.” Social Engineering : This is a term used among “hackers” for techniques that rely on weaknesses in people rather than software; the goal is to trick people into revealing passwords or other information that compromises an individual system's security. This is a lot easier said than done, but it can be done. Most telemarketing scams that rob people of money are forms of “ social engineering.” Most of these scams occur due to the individuals impersonating credit card companies and or investment firms . Those socially engineered attacks are focused on getting you to give them your money, bottom line. Transverse that process into a tech industry where a lot of people are not as computer knowledgeable and you have the “wolf in sheeps clothing!
35. Some of the most common forms of social engineering focused on any particular user is to phone up a “mark/victim” who has the required information, and posing as a field service tech or a fellow employee with an urgent access problem . This type of attack happens primarily more in business scenes. Social engineering directed to a business setting usually occur as a phone scam. The scam boils down to how believable the “hacker” sounds on the phone. They pit their knowledge and wits against another human. This technique is used for a lot of things, such as gaining passwords and basic information on a system or organization. Be it known that it’s not the only type of “social engineering” that is used. These same principles are applied when it comes to your personal computer . Chat lines make people highly susceptible to such social mayhem. CHATLINE EXAMPLE On a chat line a person isn’t evaluated by how they appear. They become as believable as their ability to write and express themselves. On a Chat Line your perception and intuition is all you have to rely on. The person on the other end of the keyboard can be nothing as they describe themselves. The same goes for E-Mail or any form of communication without visual recognition.
36. You read what they send/say to you and your own imagination is what fills in the blanks. This person may sound romantic, funny and down to earth. There is a trust value that is built up and depending on how long you’ve been on the Internet , this initial base of trust is formed very quickly. At this point after the ice has been broken so to speak the “hacker” may ask if you wish to see his/her picture. This is the turning point of your conversation. Most people would reply sure and then receive the picture from the “hacker.” This is where the situation gets interesting. The “hacker” in question has the window of opportunity to either attempt to send you a real picture or a Trojan. If the “hacker” sends you a legitimate picture, then that helps to build trust between them and you. If they go for the strike right of the bat then they risk exposing themselves. In either case their goal has been accomplished which is to get you to accept the file from them. By gaining your trust and getting you as a user to drop your guard you’ve compromised your systems security. Given it takes a certain level of finesse and grace to accomplish this type of attack. It requires the “hacker” to be socially adept, quick witted and very confident. Not usually the characteristics of the “hacker” definition.

41. FINAL WORDS Learning the system loop holes and tricks that “hackers” use is only half the process. Protecting your privacy is 90% up to you, the rest can be handled by software. You have the means and ability to protect yourself. You may think to yourself that you’re out gunned on the Internet, don’t. We all have to start learning from somewhere. Even hackers and so called “hackers” had to start learning somewhere. No one was born with the knowledge of how a computer works. The Internet is a tool by which many of these “hackers” educate themselves . You can do the same,but for the good. it remains the most powerful tool for information and development there is. More and more businesses and services are migrating to the online world. You can either, sit back and watch it go, or jump on the bandwagon and ride it out. It’s all up to you. Exercise caution when dealing with people online, but don’t be too paranoid. Enjoy the power of the Internet it can be a great asset to you or your business. The online population is growing exponentially.
42. With the recent growth of dedicated access your computer is connected to the Internet 24hrs a day. High speed access gives you the opportunity to download files at lightning fast rates. It’s a long way from the old dial up. As technology increases so must your awareness. Realistically most of us don’t care about the inner workings of the Internet . Perhaps we have a sheer curiosity of what happens behind the scenes, but none of us really believes it makes a lot of difference to us to know that information. We primarily care about getting our daily activities done and enjoying the power of the Internet. We want to be able to Log online talk to our friends and family and use the Internet as tool for our benefit. The Internet connects you to the world where if a friends from America wishes to talk to you live one on one they can flip on their webcams turn on their mics and have a video conference. It’s a cut above a phone call for a fraction of the price. Don’t let “ hackers” turn future advancements into unwanted nightmares. You as a user can prevent this by being careful. Take the extra necessary steps to protect yourself. When compared to the benefits you can have it definitely is worth an extra time. You’ve got the world at your fingertips and information at every turn. But most importantly when all is said and done, take back your privacy from those who may seek to compromise it.
