Delivers Payload Using Post Exploitation Framework
During our routine threat-hunting exercise, Cyble Research & Intelligence Labs (CRIL) came across a Twitter post wherein a researcher mentioned an interesting infection chain of the Bumblebee loader malware being distributed via spam campaigns.

Bumblebee is a replacement for the BazarLoader malware, which acts as a downloader and delivers known attack frameworks and open-source tools such as Cobalt Strike, Shellcode, Sliver, Meterpreter, etc. It also downloads other types of malware such as ransomware, trojans, etc.
