| Verdict: | Malicious activity |
| Threats: | zgRAT is a malware known for its ability to infect systems and exfiltrate sensitive data to command-and-control (C2) servers. It is primarily distributed through loader malware, as well as phishing emails. zgRAT employs various advanced techniques, including process injection and code obfuscation, to evade detection and maintain persistence on infected systems. The malware can also spread via USB drives and uses popular messaging platforms like Telegram and Discord for data exfiltration. |
