New Bumblebee Loader Infection Chain Signals Possible Resurgence
Bumblebee is a highly sophisticated downloader malware cybercriminals use to gain access to corporate networks and deliver other payloads such as Cobalt Strike beacons and ransomware. The Google Threat Analysis Group first discovered the malware in March 2022 and named it Bumblebee based on a User-Agent string it used. The Netskope Threat Labs team discovered what seems to be a new infection chain leading to Bumblebee malware infection, and our findings corroborate those shared by other researchers.
