| Verdict: | Malicious activity |
| Threats: | DarkVision RAT is a low-cost, modular Remote Access Trojan that gives attackers remote control of infected Windows hosts. Initially observed around 2020 and sold in underground marketplaces, DarkVision has become notable for its full feature set (keylogging, screen capture, file theft, remote command execution and plugin support) and for being distributed via multi-stage loaders in recent campaigns. |
