Washington (CNN Business) REvil, the ransomware gang that attacked meat supplier JBS Foods this spring and a major IT software vendor this month, has mysteriously vanished from the internet, according to cybersecurity experts tracking the group. Ransomware works by locking down a computer network, stealing and encrypting data until victims agree to pay a fee. In recent years, ransomware gangs have gone after hospitals, universities, police departments, city governments, and a wide range of other targets. A source familiar told CNN the House Intelligence Committee has not been briefed on what caused REvil to go dark. Dmitri Alperovitch, co-founder of the cybersecurity firm CrowdStrike, hypothesized that western governments may be pressuring internet infrastructure companies not to complete web browser requests for REvil's sites.
