Undercover Work in Geneva

Snowden worked for the CIA in Geneva from 2007 to 2009, not as a technician but as a covert operative with diplomatic cover. The agency provided him with a diplomatic passport and an apartment through the U.S. embassy. His assignment involved conducting electronic surveillance operations while posing as a State Department diplomat. This experience gave Snowden direct insight into how the CIA used diplomatic positions as covers for intelligence gathering in foreign countries.

Unethical Recruiting Tactics

CIA operatives in Geneva deliberately got a Swiss banker drunk at a social event and encouraged him to drive home. This resulted in a DUI arrest that the operatives then used as leverage. They offered to make the charges disappear if the banker agreed to provide financial data from his employer, UBS. Snowden witnessed this entrapment firsthand. The morally questionable blackmail tactic deeply troubled him and contributed to his growing disillusionment with intelligence work.

Network Infrastructure Hacking

The CIA, working jointly with the NSA, hacked internet routers and network backbones worldwide. This approach allowed access to communications from thousands of computers without targeting individual devices. Snowden’s leaks detailed programs like TURBINE, which automated these intrusions at scale. This strategy significantly expanded the CIA’s ability to monitor global internet traffic covertly. The programs represented a shift toward bulk collection rather than targeted surveillance of specific suspects.

<< Previous

NEXT >>

Fourth Amendment Violations

Snowden’s leaks revealed how CIA and NSA programs collected Americans’ data without warrants. Section 702 of the FISA Amendments Act enabled this surveillance, which many legal experts considered unconstitutional. The CIA accessed this information for foreign intelligence purposes but swept up domestic communications. The “incidental” collection of U.S. citizens’ communications raised serious legal questions. These concerns eventually led to modest reforms through the 2015 USA Freedom Act.

Whistleblower Protection Gaps

Snowden’s experience highlighted the lack of effective whistleblower protections for intelligence contractors. Internal complaints were frequently dismissed or led to retaliation against those who raised concerns. He pointed out that the Intelligence Community Whistleblower Protection Act contained loopholes excluding contractors like himself. This legal gap left him with limited options for reporting perceived abuses through official channels. This situation ultimately influenced his decision to leak directly to journalists.
