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.
