Bumblebee is a type of malware that has been linked to ITG23, a cyber threat group. Over the past year, it has been used in conjunction with other initial access malwares such as Emotet, IcedID, Qakbot, and Gozi during ITG23 attacks. The same values for self-signed certificates seen in Bumblebee have also been observed in HTTPS C2 traffic by other malware families. This malware spreads through various methods including phishing, malicious advertising, and SEO poisoning, according to Patrick Tiquet, vice president of security and architecture for Keeper Security. Recently, researchers at Netskope discovered a new instance of Bumblebee being used in combination with a payload not typically associated with the botnet, signaling a potential resurgence of this malware. Despite law enforcement efforts to disrupt their activities, the actors behind Bumblebee quickly reintroduced it, indicating well-prepared contingency plans. "The re-emergence of Bumblebee after Operation Endgame demonstrates the adaptability of the group believed to be responsible for its development," says Callie Guenther, senior manager of cyber-threat research at Critical Start. Once Bumblebee gains access to a network, it can potentially harvest credentials and access corporate resources, including SaaS applications. The attackers are leveraging legitimate tools like MSI installers, effectively hiding in plain sight. According to Tamir Passi, senior product director at DoControl, the latest attack chain of Bumblebee is even more challenging for defenders to spot than previous versions. This continued evolution and resilience of Bumblebee highlight the importance of maintaining robust cybersecurity measures to protect against such threats.
