Lumma Stealer is a potent malware designed to exfiltrate information from compromised systems, including system details, web browsers, and browser extensions. The malware was primarily delivered to victims through websites hosting cracked games, specifically targeting gamers. In July 2024, it was discovered that the more than 250 million estimated players of the game "Hamster Kombat" were targeted and lured into downloading Lumma Stealer by multiple simultaneous scams. By leveraging legitimate software and utilizing deceptive delivery methods, Lumma Stealer presents a persistent challenge for security teams. The malicious PowerShell script that initiated the Lumma Stealer infection downloaded and executed an archive with the malware. The Command and Control (C&C) servers associated with Lumma Stealer were active in April, May, and June 2024, indicating an ongoing campaign. Lumma Stealer was installed on Windows machines, while Atomic Stealer (AMOS) was used on Macs. A unique loader, FakeBat, has been used to drop follow-up payloads such as Lumma Stealer. In October 2024, Check Point Research highlighted a significant rise in infostealer malware, with Lumma Stealer dominating the list of prevalent threats. Researchers from various companies reported this campaign in August and September. According to Sarah Jones, a cyber-threat intelligence research analyst at Critical Start, protecting against ongoing Lumma Stealer threats requires close collaboration between threat intelligence, security operations centers (SOCs), and incident-response teams. Continuous monitoring, adaptation, and regular updating of detection rules, indicators of compromise, and security controls are crucial given the rapid evolution of threats like Lumma Stealer.
