    Study Notes

    The Big Picture

    • Attackers such as Advanced Persistent Threats (ATPs) have superior insight into how organizations are compromised, while organizations must understand the same big picture to protect themselves.
    • Understanding how and why organizations get hacked is crucial for effective security.

    Data Challenges

    • Determining the exact details of how a system was compromised is difficult because of limited reporting and the difficulty in finding and analyzing all relevant information.
    • Many compromises are never reported, discovered, or fully investigated.
    • The information available may be incomplete, misleading, or even incorrect.

    Stealthy Attacker Tactics

    • ATPs prioritize covert actions to avoid detection and maintain access to target systems.
    • They leave traces only when absolutely necessary to stay connected.
    • Organizations often fear negative publicity, damage to reputation, and potential legal issues, leading to a reluctance to report security incidents.
    • The increasing number of compromises and improved detection capabilities are driving more organizations to acknowledge and report security breaches.

    • Attackers constantly refine their strategies and techniques to exploit new vulnerabilities and create innovative attack methods.
    • Defenders are continuously developing new technologies and methods to counter emerging threats.

    Techno-Criminals vs. Cybercriminals

    • Techno-criminals use technology to facilitate traditional crimes like theft, credit card fraud, and fraud.
    • Cybercriminals, on the other hand, primarily use computers and the internet to commit crimes.

    Credit Card Skimming

    • Physical skimming devices ("skimmers") are used to steal credit card data by physically swiping cards and storing information on the device.
    • Skimmers are common in retail establishments and are now increasingly used with ATM machines.
    • Skimmers often include cameras to capture PINs, and can send stolen data via text messages or wireless connections.
    • These devices are readily available online and within criminal networks.

    Hacking Power Systems

    • In 2009, the FBI discovered a widespread incident where Puerto Rico Electric Utility customers tampered with energy meters to reduce their bills.
    • Customers used strong magnets to reduce energy consumption readings, leading to a loss of approximately $400 million annually for the company.
    • Customers could reprogram meters using devices called "optical probes," which required physical access to meters.
    • These devices are available for purchase online for around $300.

    Unsophisticated Hacking Techniques

    • Chris Chaney, a hacker known as the "Hollywood Hacker," accessed the personal email accounts of celebrities using basic techniques.
    • He employed common password reset methods by guessing email addresses and answering security questions found online.
    • Chaney forwarded emails sent and received from the hacked accounts to his own address.

    Neighborly Harassment

    • Barry Ardolf, from Minnesota, targeted his neighbor, Matt Kostolnik, by compromising his wireless network and engaging in malicious activities.
    • Ardolf cracked Kostolnik's Wired Equivalent Privacy (WEP) secure network and sent malicious emails that appeared to originate from Kostolnik's home.
    • He posted child pornography on a fake MySpace page pretending to be Kostolnik and sent emails to Kostolnik's employers impersonating him.
    • Ardolf was caught by analyzing captured data packets that revealed his IP address.

    Understanding Empirical Data in Cybersecurity

    • ATP (Advanced Persistent Threat) actors often employ stealthy methods to compromise targets, minimizing their digital footprint.
    • Many organizations do not report security compromises, fearing negative publicity, customer confidence loss, or legal repercussions.
    • Organizations are increasingly reporting compromises due to the rise in attacks and improved detection capabilities.
    • Attackers continuously evolve their strategies and techniques to exploit vulnerabilities and create new attacks.
    • Defenders constantly develop new defensive technologies to counter evolving attack methods.

    Examples of Threat Actors

    • Techno-Criminals: Utilize technology to enhance traditional crimes rather than being purely digitally focused
    • Skimmers: Devices used to steal credit card data by physically swiping cards, often found in retail establishments, ATMs, and increasingly incorporating wireless technology and cameras.
    • Hacking Power Systems:
      • Cases of manipulating energy meters in Puerto Rico, costing the utility company millions annually.
      • Attackers used magnets and "optical probes" to manipulate readings and reduce energy bills.
      • Devices are readily available online, requiring minimal technical expertise.

    Unsophisticated Threat Actors

    • Chris Chaney ("Hollywood Hacker"): Gained access to celebrities' email accounts through simple methods:
      • Guesses email addresses.
      • Exploits "forgot password" features by guessing security questions easily found online.
      • Forwards emails to monitor account activity.
    • Barry Ardolf: Terrorized his neighbor using a combination of social engineering and technical tricks.
      • Cracked the neighbor's WEP-secured wireless network.
      • Spread malicious emails traced back to the neighbor's home.
      • Created a fake MySpace page with child pornography and pretended to be the victim.
      • Sent emails impersonating the victim to their employees.
      • Captured network data exposed his IP address and led to his capture.

    Understanding Empirical Data in Cybersecurity

    • This chapter focuses on providing empirical examples of hacking and counter-hacking.
    • These examples offer insights into how attackers compromise organizations and how those organizations respond.

    The Problem with Data Sets

    • Many incidents go unreported or have limited available information.
    • Not all compromises are discovered.
    • Not all discovered compromises are reported.
    • The full facts surrounding specific compromises are often uncovered.
    • Even when facts are released, they may be misleading or incorrect.

    Attackers' Operational Methods

    • Advanced Persistent Threat (ATP) attackers typically favor stealthy methods to avoid leaving traces.
    • These methods can be sophisticated and help them to maintain access to compromised organizations.

    Issues Surrounding Reporting Organizational Breaches

    • Many organizations choose not to report breaches due to concerns about:
      • Bad publicity
      • Loss of customer confidence
      • Potential legal actions
    • The increase in breaches and the ability to detect them has led to a greater willingness among organizations to report.

    Evolving Threat Landscape

    • Attacker tactics are constantly changing to:
      • Exploit new vulnerabilities
      • Create new attacks
    • Defenders develop new technologies to counter these threats.

    Techno-Criminals & Skimmers

    • Techno-criminals utilize technology to facilitate traditional crimes, unlike Cybercriminals who use computers and the internet for their crimes.
    • Skimmers are physical devices used to steal credit card data.
    • They are often placed on ATM machines, particularly in areas of high card usage, such as restaurants or retail stores.
    • Modern skimmers can send captured data via text messages or wireless methods and often include micro-cameras to capture PINs.
    • These devices are readily available through online markets and criminal underground networks.

    Hacking Power Systems

    • In 2009, the FBI discovered a large-scale scheme in Puerto Rico where customers manipulated energy meters to reduce their bills.
    • 10% of the meters were modified, costing the utility company $400 million annually.
    • Attackers used strong magnets to slow down the meters, reducing energy readings by 50-75%.
    • They also employed devices like “optical probes” to reprogram the meters; these devices require physical access to meters and can be purchased online.
    • These techniques highlight the potential vulnerabilities of critical infrastructure to relatively unsophisticated attackers with physical access.

    Hollywood Hacker (Chris Chaney)

    • Chris Chaney, despite lacking technical skills, targeted celebrities' email accounts.
    • He was arrested for distributing nude photos of celebrities, including Scarlett Johansson.
    • Chaney employed simple methods to gain access, including:
      • Guessing email addresses
      • Utilizing "forgot password" features of free email services
    • He would reset passwords by answering security questions that could be easily found online.
