Study Notes

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.
