About this tag
Phishing attacks on WindowsForum.com cover a range of sophisticated techniques that bypass traditional defenses. Recent discussions highlight device-code flow abuse in Microsoft 365, where attackers like Jalisco and Kali365 use legitimate OAuth sign-in flows to hijack accounts without stealing passwords, rendering multi-factor authentication ineffective. Other threads examine ClickFix scams that trick users into pasting encoded commands into Windows Terminal to deploy Lumma Stealer, and the Reprompt attack on Microsoft Copilot Personal that enables one-click data exfiltration. Additional coverage includes Russian phishing campaigns targeting encrypted messaging apps, the security benefits of switching to passkeys, and UI spoofing flaws in Microsoft Edge. These topics emphasize the evolving nature of phishing and the need for advanced defenses beyond traditional password security.
