Deep Instinct’s Threat Research Lab recently noticed a new strain of a JavaScript-based dropper that is delivering Bumblebee and IcedID. The dropper contains comments in Russian and employs the unique user-agent string “PindOS”, which may be a reference to current (and past) anti-American sentiment in Russia.
Bumblebee is a malware loader first discovered in March 2022. It was associated with Conti group and was being used as a replacement for BazarLoader. It acts as a primary vector for multiple types of other malware, including ransomware.
IcedID is a modular banking malware designed to steal financial information. It has been seen in the wild since at least 2017 and has recently been observed shifting some of its focus to malware delivery.
Recently (On March 18 2023 at 23:44), a new malspam campaign has been observed in the wild ( HERE ), which caused a significant amount of concern. This campaign is designed to distribute malicious emails, which contain a harmful payload that can infect a user’s system, steal sensitive information, or launch other types of attacks.
