NOBELIUM is the group behind the SUNBURST backdoor, TEARDROP malware, GoldMax malware, and other related components. Known for its undetectable attack techniques, NOBELIUM’s recent malicious email campaign was detected in January 2021 by the Microsoft Threat Intelligence Center. After experimenting with and evolving the delivery techniques, NOBELIUM targeted 3,000 individual accounts spanning 150 countries. The campaign reached its peak when the group utilized a legitimate mailing service called Constant Contact to deliver malicious payloads.

This is an ongoing and active threat as of September 29, 2021. Though it may seem like a typical phishing email containing dubious links, it’s more than that. The sophisticated techniques used by NOBELIUM to deliver malicious payloads require special attention.
