Security experts are sounding the alarm on a new phishing scheme that exploits Microsoft’s authentication system. Hackers are impersonating Microsoft’s Active Directory Federation Services (ADFS) to trick individuals into revealing their passwords and login credentials. The attack begins with a phishing email, purporting to be from the target company’s IT department, instructing users to re-authenticate due to a system upgrade. The email contains a deceptive link that leads victims to a fake ADFS login page, mirroring the organization’s actual site.
This phishing campaign specifically targets organizations in sectors such as education, healthcare, and the public sector, with approximately 150 entities falling victim so far. The attackers aim to steal sensitive information, such as login details and multi-factor authentication (MFA) codes, in a financially motivated effort rather than for espionage purposes.
In a sophisticated move, the phishing page captures the victim’s details before redirecting them to the real sign-in page to avoid detection. The cybercriminals then use the stolen login information to access accounts, extract data, establish new email rules, and attempt to infiltrate the target network. It highlights the importance of staying vigilant against such threats in the digital landscape.
