LONDON — The Associated Press has found that an undercover operative targeted cybersecurity experts in an apparent effort to gather intelligence about critics of Kaspersky Lab, the Russian antivirus firm.

Kaspersky Lab declined to answer questions from the AP about whether it had any involvement with the meetings.

The mystery over who hired the spy lingers, but it’s an illustration of how those who cross wealthy individuals, major corporations or authoritarian governments can find themselves embroiled in elaborate espionage operations.
