Analysis Summary
The BazarLoader malware is a small backdoor (a TrickBot adjacent malware) to an infected victim Windows host. BazarLoader currently uses a BazarCall method that infects the victim’s system and provides cybercriminals with backdoors that can be used in the future to send follow-up malware, scan the environment and exploit other vulnerable hosts on the network.
Researchers have reported the latest method used by threat actors to spread the malware; the call-center-based bazarLoader distribution method utilizes emails with a trial subscription-based theme that encourages potential victims to call a phone number. The victim is hoodwinked into thinking that they have subscribed to a service they didn’t sign up for and are directed to call a certain number for help. The call center operator directs the victim into downloading an infected excel sheet that is installed upon unsubscribing from the service.
