GoKawiilGoogle threat analyst secretly monitored TeamPCP hacking group's internal operations
A Google Threat Intelligence Group analyst named Larsen ran a covert operation to observe the hacker collective TeamPCP, gaining access to a server where the group stored stolen credentials from numerous victim companies. Google used this visibility to rapidly notify cloud providers like AWS and Microsoft to revoke compromised access tokens before the hackers could exploit them for extortion, rather than trying to contact each victim individually.
