Threat Intelligence Brief
Curated summary with source attribution

Threat Risk: High
Victim: General Windows users and corporate employees
Incident: The resurgence of Lumma Stealer malware following multiple global law enforcement takedowns.
Impact: Theft of browser passwords, session cookies, 2FA tokens, and cryptocurrency wallet data across 394,000 PCs.
Attacker: Lumma Stealer operators
Analysis: Lumma Stealer continues to thrive as a Malware-as-a-Service (MaaS) operation, demonstrating high resilience against international takedown efforts. The latest campaigns utilize social engineering and ‘ClickFix’ prompts to trick users into manually executing malicious code via the Windows Terminal. This approach bypasses many traditional security triggers by relying on user-initiated execution.
Recommendations: Restrict or monitor the use of Windows Terminal and PowerShell for non-administrative users.; Train staff to recognize and report ‘ClickFix’ prompts and suspicious manual command entries.; Deploy phishing-resistant MFA to limit the utility of stolen session cookies and passwords.
