Analysis Summary
The malware loader, Bumblebee, is used to download Cobalt Strike and perhaps other malware such as ransomware. It also replaces the BazarLoader backdoor, which is previously used to transmit ransomware payloads. This new malware is linked to a number of threat actors, including several well-known ransomware.
According to researchers, the appearance of Bumblebee in phishing attempts in March correlates with a drop in the use of BazarLoader for distributing file-encrypting malware.
Bumblebee is distributed in the form of ISO files that contain malicious DLL and shortcut files. It employs different techniques to avoid detection. It can determine virtualization environment processes to prevent operating on virtual machines. Banking information, password, and identity theft are the main impact of this malware.
Bumblebee malware is designed to download and run additional payloads in order to infect computers with other malware. Bumblebee can be used to inject information stealers, cryptocurrency miners, and other malware since it is designed to drop extra payloads. The C2 (Command and Control) server is where Bumblebee gets commands. It is used by attackers to download and execute files directly, inject malicious DLLs, and create operating system persistence. This new malware is linked to a number of threat actors, including several well-known ransomware.
