Emotet, formerly referred to as the most dangerous malware, was originally identified in 2014 as a banking Trojan. Since then, it has developed into the cybercriminals’ go-to tool. 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 or Macro-embedded Microsoft Word files. 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.
