How and Why to Make Email Everyone's BusinessSendio
This document discusses the threats posed by email security breaches such as spam, phishing, and spoofing. It notes that in Q3 of 2013, 3.9% of all email contained malicious attachments, 68.3% was spam, and since 2005 there have been over 3,763 data breaches exposing over 608 million records in the US. The document recommends ways for companies to protect their networks from such threats, including using anti-virus software, anti-spoofing technology, email communities, and IP address reputation monitoring. It also stresses the importance of notifying affected parties if a breach occurs.
This document discusses various phishing techniques used by hackers to steal personal information. It describes instant messaging phishing using fake websites, key loggers that record keyboard inputs, session hacking that exploits web session controls, search engine phishing through fraudulent product sites, phone phishing using fake caller IDs, and malware phishing using emails with malicious attachments. The document stresses the importance of understanding these techniques to protect oneself from becoming a victim of phishing attacks.
This document discusses phishing attacks and anti-phishing software. It defines phishing as a social engineering technique where attackers try to steal personal information by impersonating trustworthy sources. The document notes that over 90% of online attacks start with phishing emails, and 76% of companies experienced a phishing attack in 2019. It then introduces a proposed anti-phishing solution called "Phishy Bait" that uses natural language processing to read emails and detect malicious ones based on spelling mistakes, urgency, long URLs, IP addresses instead of domains, and other red flags.
Are you a hacker’s target? How do they get your information? In the world of network security, cybercrime and information warfare, it’s important to protect yourself. Check out the infographic below and let us know: how have you been a hacker’s target?
This document provides information about phishing attacks and how to identify them. It defines phishing as fake emails constructed to trick users into clicking links or opening attachments to steal login credentials. Over 50% of users interact with phishing emails within the first hour, and two thirds of cyber espionage incidents use phishing. The document outlines common traits of phishing emails like generic greetings and requests for urgent action. It emphasizes that human detection of phishing is more effective than technology alone and provides tips on verifying links and reporting any suspicious emails.

Krutarth Vasavada presented on ethical hacking and cybersecurity. He began with definitions of ethical and hacking. Ethical hacking involves authorized access to computer systems to test security without malicious intent. Vasavada discussed why individuals and organizations are interested in hacking, including to understand current security status. He covered common types of attacks like denial of service, malware, and social engineering. The causes of attacks include footprinting, sniffing, fingerprinting and password hacking. Prevention requires unique approaches depending on the target. Ethical hackers can help by understanding vulnerabilities and having no malicious intent. Career opportunities in ethical hacking require skills and certifications in computer systems, programming, and networking.
This document discusses managing privacy and digital risk. It defines privacy as having control over personal information and limiting who can access it, what can be done with it, and the purposes of use. Digital risk is defined as the threat multiplied by vulnerability. Threat has increased geometrically due to more devices and connections creating complexity and unpredictability. Vulnerabilities have also increased exponentially. This has reduced privacy risk perception and increased the types and impacts of privacy risks related to speed, dispersion, persistence, and clustering of personal information. Identity information like names and payment details are most valuable and at risk. Risk management frameworks are proposed to analyze assets, connections, and value to determine high risk areas and mitigation strategies.
The document discusses goals and strategies for defensive information warfare, including protecting information resources from attacks that decrease availability to both offense and defense or decrease integrity. It outlines key areas of prevention, deterrence, detection, emergency preparedness, and response. Main goals are to provide cost-effective defense without limiting organizational capabilities.
Chapter 6
Authenticating People
Chapter 6 Overview
The three authentication factors: what you know, you have, and you are
Passwords, password bias, and search space calculations
Cryptographic building blocks: random choice, one-way hash
Authentication devices: personal tokens and biometrics
Basic issues in authentication policy
Elements of Authentication
Authentication Factors
Something you know
Password or PIN
Something you have
Key or token
Something you are
Personal trait
Traditional parallel terms:
Something you know, are, have
Multi-factor Authentication
Using different factors in authentication
NOT two or three instances of the same factor
Two-factor authentication
ATM authentication: ATM card + PIN
Biometric laptop: Fingerprint + password
NOT: Password + PIN
Three-factor authentication
Biometric access card: fingerprint + card + PIN
NOT: fingerprint + PIN + password
Authentication Threats
Focus in this chapter
Trick the authentication system or access assets through the system
No “remote” attacks via Internet or LAN
Threats must have physical access to system
Range of threats
Weak threat – authentication is effective
Strong threat – authentication may work
Extreme threat – authentication not effective
Attacks on Authentication
Password Authentication
Each User ID is associated with a secret
User presents the secret when logging in
System checks the secret against the authentication database
Access granted if the secret matches
Risks
Shoulder surfing at the keyboard
Reading the password off of printer paper
Sniffing the password in transit or in RAM
Retrieving the authentication database
Password Hashing
One-Way Hash Functions
A Cryptographic Building Block function
We will see more building blocks later
Input:
An arbitrarily large amount of data, from a few bytes to terabytes – RAM or files or devices
Output:
A fixed-size result
Impractical to reverse
Minor change to input = big change to output
Sniffing Passwords
Goal: intercept the password before it is hashed
Keystroke loggers
In hardware: Devices that connect to a keyboard's USB cable
In software: Procedures that eavesdrop on keyboard input buffers
Password Guessing
DOD Password Guideline (1985) required a minimum 1 in a million chance of successful guessing.
This was designed to defeat interactive password guessing: A person or machine made numerous guesses
Some guessing succeeds based on social and personal knowledge of the targeted victim
Modern network-based guessing can try tens of thousands of alternatives very quickly.
Off-line Password Cracking
How Fast Is Off-line Cracking?
It depends on the size of the search space
i.e., how many legal – or likely – passwords?
Legal passwords are limited to specific sets of characters, typically from the ASCII set
Single-case letters only:
Two letter passwords = 262
Three letter passwords = 263
… etc.
Password with L letters = 26L
Increasing the Search Space
Two options
Increase L – the length of pas ...

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
