Outcome:
Sentenced to life imprisonment without parole.
Significance:
Classic example of an insider threat in national security.
Demonstrates how financial irregularities, lifestyle audits, and internal controls are key in detecting insider threats.
2. United States v. Edward Snowden (2013)
Facts:
Edward Snowden, a contractor for the NSA, leaked classified information about global surveillance programs to journalists.

The NSA traced unauthorized access to classified databases.
Digital forensic analysis revealed Snowden downloaded large volumes of sensitive files.
Security protocols flagged unusual patterns of access and data transfer.
Prosecution:
Charged under the Espionage Act of 1917 for theft and unauthorized disclosure of national defense information.
Snowden fled the U.S. to avoid arrest.
Outcome:
No trial due to his asylum abroad; remains a controversial case in legal and ethical debates.
Significance:
Highlights challenges in prosecuting insider threats when the individual leaks information for perceived public interest.
Shows the importance of digital monitoring, audit trails, and access controls.
3. R v. John Stonehouse (1976, UK)
Facts:
John Stonehouse, a Member of Parliament, faked his death to claim insurance and hide debts. Although this was primarily fraud, his insider knowledge of government systems and positions allowed him to manipulate public office for personal gain.

Shows that insider threats are not only technological; positions of trust can be exploited for financial crimes.
4. U.S. v. Chelsea Manning (2010–2013)
Facts:
Chelsea Manning, an Army intelligence analyst, leaked hundreds of thousands of classified military and diplomatic documents to WikiLeaks.
Investigation:
Monitoring of network activity revealed unusual downloads of classified files.
Internal audits and log reviews identified Manning’s user credentials accessing restricted information.
Digital forensic analysis confirmed the transfers to external sources.
Prosecution:
Charged with violations of the Espionage Act, theft of government property, and aiding the enemy.
Outcome:
Convicted and sentenced to 35 years imprisonment (later commuted to ~7 years).
Significance:
Insider threats can involve digital exfiltration on a massive scale.
Emphasizes the role of audit logs, access controls, and monitoring systems in detecting malicious insiders.
5. U.S. v. Harold Martin (2016)
Facts:
Harold T. Martin III, a contractor for the NSA, amassed tens of terabytes of classified data over 20 years, including sensitive cybersecurity information.
Investigation:
Internal review and tip-offs triggered examination of Martin’s computer systems.
Forensic analysis revealed unauthorized retention of highly classified data.
Prosecution:
Charged with willful retention of national defense information under the Espionage Act.
Outcome:
Pleaded guilty in 2019 and sentenced to 9 years in prison.
Significance:
Highlights the threat posed by long-term, trusted insiders who accumulate sensitive data.
Demonstrates the importance of continuous monitoring and auditing of personnel with access.
6. R v. Christopher John Boyce (US, 1977)
Facts:
Christopher Boyce, a U.S. defense contractor, sold classified satellite information to the Soviet Union. His co-conspirator was Andrew Daulton Lee.
Investigation:

Establishing intent is critical; negligence vs. malicious intent must be distinguished.
Legal frameworks like the Espionage Act or fraud statutes are commonly used.
Insider Threat Patterns:
Can be malicious (espionage, theft) or negligent (accidental data leaks).
Can involve digital systems, physical records, or abuse of position.
