Trellix released a recent report on the evolution of BazarCall social engineering tactics. Initially BazarCall campaigns appeared in late 2020 and researchers at Trellix noticed a continuous growth in attacks pertaining to this campaign.
Reports say at first, it delivered BazaarLoader (backdoor) which was used as an entry point to deliver ransomware. A BazaarLoader infection will lead to the installation of Conti Ransomware in a span of 32 hours.
It was also found to be delivering other malware such as Trickbot, Gozi IFSB, IcedID and more. In this case, “BazarCall has ceaselessly adapted and evolved its social engineering tactics”. These campaigns were found to be most active in United States and Canada. They were also targeting some Asian countries like India and China.
