About this tag
Phishing remains a central threat for Windows and Microsoft 365 users, with recent campaigns exploiting legitimate sign-in flows and AI tools. Attackers now abuse OAuth device-code flows, as seen in the Jalisco and Kali365 campaigns, to bypass MFA and hijack accounts without fake login pages. Microsoft 365 billing scams target payment details, while ClickFix tactics use Windows Terminal to deliver Lumma Stealer. AI chatbots like ChatGPT can help identify phishing red flags but cannot verify sender legitimacy. CISA and FBI warnings highlight Russian phishing against encrypted messaging accounts, and a Reprompt attack on Copilot Personal shows data exfiltration risks. Administrators should block malicious domains and review authentication policies.

    BEC Defenses Beyond AI Executive Impersonation Claims

    Passkey Lures Target Cloud Accounts, Not Passkeys

    Microsoft’s latest account of cloud intrusions is easy to misread from its passkey-themed framing. The important finding is not that FIDO2 passkeys have been bypassed by a fake website. Rather, attackers used the idea of a passkey, MFA, or SSO update to create urgency, steer employees into...

    BigBear 2.0 and Microsoft 365: Why MFA Can Still Be Phished

    A reported phishing-as-a-service campaign called BigBear 2.0 is a useful reminder that multifactor authentication is not the end of the Microsoft 365 security conversation. The reported technique does not crack MFA, exploit a disclosed Microsoft 365 flaw, or prove that FIDO2 security keys were...

    Unicode Tag Spam: What Microsoft’s Phishing Data Shows

    Microsoft’s latest look at a high-volume phishing operation is a reminder that email evasion does not always require a malicious attachment, a novel exploit, or an AI-generated hidden command. In this case, the trick was smaller: invisible Unicode tag characters inserted into finance-themed...

    ChatGPT Can Spot Phishing Red Flags, Not Verify Senders

    Using ChatGPT, Claude, or Gemini to explain a suspicious message can help a user slow down before acting, but it cannot establish that a text or email is legitimate.
