Chapter 2 Cybersecurity Threat Landscape

Motivations Behind Cyberattacks

• Data exfiltration aims to acquire sensitive or proprietary information, like customer data or intellectual property.
• Espionage involves stealing secret information, often between nation-states or corporate rivals.
• Service disruption attacks target critical systems (e.g., banking, health-care), causing interruptions.
• Blackmail seeks to extort victims by threatening to release sensitive information or continue attacks.
• Financial gain focuses on money theft or fraud, common among organized crime groups.
• Philosophical or political beliefs drive hacktivists to promote specific ideologies or causes.
• Ethical attacks, also known as white-hat hacking, aim to uncover vulnerabilities with organization consent.
• Revenge attacks are motivated by personal vendettas, targeting individuals or organizations for retribution.
• Disruption/chaos attacks aim to create disorder and interrupt normal operations.
• War can also motivate cyberattacks, often tied to national interests.

Characteristics of Threat Actors

• Cyber attackers vary in sophistication, from unskilled individuals using simple scripts to advanced persistent threats (APTs) that utilize advanced techniques.
• Resources available to attackers differ significantly; organized crime often has extensive funding, unlike hobbyist attackers.
• Intent and motivation play roles in attack types, with some seeking thrills (unskilled) versus others pursuing financial or political objectives.

Attack Techniques and Vectors

• Attackers may gain initial access via various methods including the Internet, wireless networks, or direct physical access.
• Common tactics involve social engineering through email or social media, or using removable media to compromise networks.
• Shadow IT systems can introduce vulnerabilities by exposing data to unapproved applications or devices.
• Supply chain interference is a strategy employed by sophisticated attackers to disrupt organizations.

Role of Threat Intelligence

• Threat intelligence informs organizations of potential threats and vulnerabilities through public and private sources.
• Security teams combine external intelligence with their analytics to identify indicators of compromise.
• Understanding different threat actors—unskilled attackers, hacktivists, organized crime, APTs, and insider threats—is essential for effective defense.

Understanding Unskilled Attackers

• Script kiddies refer to unskilled attackers who rely on downloaded tools rather than in-depth understanding.
• While they may seem less dangerous, their access to automated tools makes them a persistent threat.
• Unskilled attackers often target vulnerable organizations indiscriminately, including schools and universities, as they're convenient targets.
• Motivations frequently center around proving their hacking abilities rather than achieving financial gain.

Attack Surfaces and Vectors

• Attack surfaces include systems, applications, or services with vulnerabilities that attackers can exploit.
• Reducing the attack surface is key for security professionals to mitigate risks.
• Email is a primary threat vector, facilitating phishing, spam, and other attacks that can compromise multiple users.
• Attackers only need one successful phishing attempt to access an organization's network.
• Other communication methods, like SMS (smishing), instant messaging, and voice (vishing), can also serve as threat vectors.
