mfa phishing

MFA phishing attacks exploit trust in collaboration tools like Microsoft Teams to bypass multi-factor authentication. Recent research from Palo Alto Networks Unit 42 shows attackers impersonate IT staff, tricking users into approving MFA prompts or visiting credential-harvesting pages. These attacks target Microsoft 365 environments, turning the collaboration layer into an identity attack surface. Defenders must reconsider default open external chat policies and implement stronger verification measures. This tag covers the latest techniques, real-world examples, and defensive strategies against MFA bypass via social engineering in enterprise settings.
