| Verdict: | Malicious activity |
| Threats: | Chaos ransomware is a malware family known for its destructive capabilities and diverse variants. It first appeared in 2021 as a ransomware builder and later acted as a wiper. Unlike most ransomware strains that encrypt data to extort payment, early Chaos variants permanently corrupted files, while later versions adopted more conventional encryption techniques. |
