| Verdict: | Malicious activity |
| Threats: | The Jigsaw ransomware, initially detected in 2016, encrypts files on compromised systems and requires a ransom payment in Bitcoin. If the ransom is not paid, the malware starts deleting files, increasing the pressure on victims to comply. Its source code is publicly accessible, allowing various threat actors to customize and repurpose the malware for different objectives. |
