Microsoft has discovered a North Korean hacking campaign that exploited a zero-day vulnerability in the Chromium browser earlier this month. The hacking group, known as Citrine Sleet, targeted organizations to steal cryptocurrency. This cyber attack involved tricking victims into visiting a web domain controlled by the hackers, allowing them to execute remote code. The vulnerability was quickly patched by Google two days after its discovery. Microsoft identified the attack on August 19. Since 2017, North Korean hackers have reportedly stolen $3 billion in cryptocurrency through various cyber campaigns. The Citrine Sleet group is linked to North Korea's Reconnaissance General Bureau.
