It looked like a crypto investment until €460 million vanished. Operation BORRELLI dismantled a global fraud ring that scammed over 5,000 victims, with arrests in Madrid and the Canary Islands. A fake workforce was quietly funding a real regime. The DoJ disrupted a North Korean scheme where remote IT workers used stolen identities to get jobs at over 100 U.S. companies. The operation funneled $5 million to the DPRK, exposed military tech, and led to raids across 16 states.

North Korean actors are deploying NimDoor malware to infiltrate Web3 and crypto platforms using social engineering via Telegram. Google has patched CVE-2025-6554, a critical zero-day in Chrome’s V8 engine that was exploited in the wild to execute arbitrary code.
