| Verdict: | Malicious activity |
| Threats: | Cerber is a Ransomware-as-a-Service (RaaS) that appeared in 2016, spread quickly and has been evolving since. It became well-known for its file encryption, offline capabilities, and sophisticated evasion techniques. It primarily targets enterprises, financial institutions, and government entities, encrypting their data and demanding ransom payments in Bitcoin. It also targets everyday users encrypting personal files (photos, documents) with the risk of their permanent loss. |
