XKeyscore and Mass Surveillance

Mass Surveillance and XKeyscore

• XKeyscore is a search engine utilized by the NSA and "Five Eyes" alliance (US, UK, Canada, Australia, New Zealand) for accessing extensive data archives.
• The system collects a wide array of data, including emails, SMS messages, chats, address books, and browsing histories.
• Analysts can remotely search through this accumulated data, allowing them to request specific information which is then extracted for their needs.
• Trafficthief is a notification mechanism alerting analysts to noteworthy activities of their targets.
• XKeyscore can also identify new potential targets using queries to locate exploitable machines in specific regions and tools like Mugshot for machine fingerprinting.

Cybercrime Categories

• Identity Theft: Involves stealing personal information to impersonate individuals for financial gain, such as opening bank accounts.
• Theft of Service: Unauthorized use of services like internet or streaming; sharing passwords can lead to prosecution in certain jurisdictions.
• Network Intrusion: Common cyber attack leading to other crimes, e.g., unauthorized access to a neighbor's WiFi network.
• Posting Illegal Material: Distribution of pirated content or illegal materials such as child pornography.
• Fraud: Deceptive practices aimed at obtaining information or access for financial benefit or causing harm.
• Embezzlement: A financial fraud involving theft or misappropriation of funds.

Emerging Cybercrime Trends

• Ransomware-as-a-Service (RaaS): Platforms allowing individuals to conduct ransomware attacks without extensive technical skills, risking permanent file loss despite ransom payment.
• Hacktivism: Cyberattacks aimed at protesting against government or corporate entities, frequently involving denial-of-service attacks and doxing of individuals.
• Online Shaming: Publicly criticizing or humiliating individuals through digital platforms.

Mass Surveillance Techniques

• Mass surveillance encompasses monitoring and data collection of a population to combat threats or gather evidence.
• Involves both governmental espionage and data harvesting by corporations for targeted advertising, raising privacy concerns.
• Tempora: A method for intercepting data from international fiber optic cables.
• Muscular: Another technique for gathering data as it transmits between the data centers of major companies such as Yahoo and Google.

Cybercrime Tactics

• Dumpster Diving: The act of retrieving discarded personal information; legality hinges on whether the activity occurs on private property.
• Malicious Code: Includes various types of malware such as viruses, spyware, and ransomware.
• Unauthorized Data Alteration: Involves the illegal modification or destruction of information without proper consent.

Denial of Service Attacks

• DoS and DDoS: Deliberate overload of systems, rendering them unable to serve legitimate users; DDoS is larger in scale and more complex to mitigate.

Cyberbullying and Cyberstalking

• Emerging forms of crime where online resources are exploited for harassment (cyberbullying) or tracking individuals (cyberstalking).

Cyberterrorism

• Utilization of the internet to instigate significant harm for political objectives; its definition and implications are subject to debate and are linked to information warfare.
