In BazaCall, a “vishing-like” method is used in which victims receive email messages notifying them that subscription fees apply or their subscription will expire if they don’t call a particular phone number.
A new campaign was identified in which fake call centers are tricking victims into downloading malware, performing data exfiltration, and deploying ransomware on the affected machine. The attack is called BazaCall.
This new campaign was discovered and reported by Microsoft 365 Defender Threat Intelligence Team. The researchers noted that BazaCall attacks could quickly spread within a network and carry out extensive credential and data theft. It can also distribute ransomware within just 48 hours of the compromise.
