| Verdict: | Malicious activity |
| Threats: | Sality is a highly sophisticated malware known for infecting executable files and rapidly spreading across networks. It primarily creates a peer-to-peer botnet that is used for malicious activities such as spamming, data theft, and downloading additional malware. Sality has strong persistence mechanisms, including disabling security software, making it difficult to remove. Its ability to spread quickly and silently, along with its polymorphic nature, allows it to evade detection by traditional antivirus solutions. |
