The record-breaking $6.3 billion hot wallet hacking incident at Binance, which occurred on the 29th, has been revealed to be an internal infiltration by a North Korean hacking group using a disguised job interview. According to Reuters and industry analysis on the 3rd, the attackers utilized the notorious hacking technique known as the "Contagious Interview," a method frequently employed by North Korea's Reconnaissance General Bureau. They offered an attractive fake job opportunity to a DevOps engineer, sending malware disguised as a coding test program, and gained internal network access through the compromised engineer's laptop. The attackers then exploited the hot wallet's automatic signing module across 10 mainnets, siphoning off massive funds in just 20 minutes.
