YARA Signatures
MalwareBazaar uses YARA rules from several public and non-public repositories, such as YARAhub and Malpedia. Those are being matched against malware samples uploaded to MalwareBazaar as well as against any suspicious process dumps they may create. Please note that only results from TLP:CLEAR rules are being displayed.
| Rule name: | EmmenHTAl |
|---|
| Rule name: | IDATDropper |
|---|---|
| Author: | NDA0E |
| Description: | Detects modified versions of dialer.exe, BthUdTask.exe, and dvdplay containing embedded JavaScript. The JS executes an obfuscated PowerShell command which either downloads IDATLoader in an archive, or an executable (not IDATLoader) which is loaded into memory. The modified PE will only run if it's executed as an HTML Application (.hta). |
