An Undercover Google Analyst Infiltrated a Notorious Supply Chain Hacking Gang

Before two of its alleged members were arrested and charged in Australia last month, the hacker group known as TeamPCP carried out a hacking spree unlike any other in history. It tainted hundreds of open-source programs with its malware, stole developer accounts to perpetuate that software supply chain hacking, and even released a Dune-themed self-spreading worm to automate the process, ultimately breaching more than a thousand companies.

Now Google’s threat intelligence group has revealed that during a key moment of TeamPCP’s rampage, the company’s own undercover researcher had infiltrated the group—allowing Google to monitor the hacking spree from the inside, warn breach targets, and even help disrupt the group’s attempts to exploit those victims.
