Fake Passkeys and CEO Impersonation: Microsoft Exposes Two Nasty Cloud Attack Campaigns
Microsoft has revealed two threat actor campaigns targeting organizations: one involving over a million scam emails impersonating CEOs to trick finance departments into making fraudulent ACH transfers, and another using passkey-themed social engineering to compromise Microsoft cloud accounts. The second campaign involves attackers posing as IT helpdesk staff to lure employees into fake Microsoft sign-in pages, enabling credential theft or unauthorized account access, after which they establish persistent MFA footholds and exfiltrate data from SharePoint, OneDrive, and Exchange. Microsoft has linked the activity to multiple threat actors, including Storm-3032 (identified as UNC6671), with overlaps noted in shared phishing infrastructure associated with the cybercrime collective also tracked as Cordial Spider.
EvilTokens Phishing Kit Is Far Nastier Than Anyone Realised
EvilTokens, a device-code phishing kit capable of bypassing multi-factor authentication on Microsoft 365, has been found to be more sophisticated than previously understood, with Cisco Talos uncovering a linked phishing-as-a-service operator panel called "ARToken." Talos revealed how the phishing lures reach victims' inboxes, describing a targeted approach that exploits real vendor relationships and abuses legitimate SharePoint domains to evade detection. Beyond simple credential theft, ARToken includes a comprehensive post-exploitation toolkit with full business email compromise capabilities, making it a complete BEC operations platform rather than just a phishing kit.
