Push Security disclosed ConsentFix v3, a new attack that lets criminals take over Microsoft 365 accounts even if the victim has MFA and phishing-resistant passkeys turned on. The trick: instead of stealing a password, the attacker tricks the user into pasting a Microsoft authorization URL into a phishing page during what looks like a routine login. That URL contains a one-time code that the attacker exchanges for permanent access tokens. v3 automates the whole attack with Cloudflare Pages phishing sites, Pipedream webhook automation, and tenant fingerprinting that customizes the lure to each target organization's branding.
The FBI Atlanta Field Office and Indonesian authorities have dismantled the W3LL global phishing platform and arrested its alleged developer. W3LL sold a sophisticated phishing kit designed specifically for bypassing multi-factor authentication on Microsoft 365 accounts using adversary-in-the-middle (AiTM) techniques. The platform operated as a phishing-as-a-service ecosystem with its own marketplace, support channels, and licensing model, enabling thousands of business email compromise campaigns targeting corporate Microsoft 365 environments. This is described as the first coordinated international law enforcement action against this platform. Group-IB previously estimated W3LL's tools had been used to compromise over 8,000 Microsoft 365 business accounts.
