Severity

High

Analysis Summary

Emotet was initially discovered in 2014 when it infected clients of German and Austrian institutions. Emotet serves as a downloader for other malware variants like TrickBot, QakBot, and IcedID. Phishing attempts are the most common way to propagate emotet trojan, which employs an email with malicious links. It has mostly been used to attack the banking industry. Emotet can launch several malware payloads depending on the target system after deployment. Emotet is frequently used as a downloader for other malware and is a particularly common delivery method for banking Trojans such as Qakbot and TrickBot. Emotet can steal data such as saved user passwords on the browser by eavesdropping on network traffic. Its modules focus on credential theft, email theft, and spamming.

By employing a password-protected VBA project and obfuscated macros, Emotet tries to evade discovery. Additionally, it receives updates from C2 servers. This gives attackers the ability to put newer versions of the software into use, add new infections, or steal data like user credentials.
