Rewterz Threat Alert – Fake Microsoft Login Page Hidden by Captcha to Evade SEGs – IoCs

September 12, 2019

Severity

Medium

Analysis Summary

Indicators of Compromise have been identified for a campaign using captcha boxes to hide a fake Microsoft account login page from secure email gateways (SEGs). The attackers were after credentials for Microsoft accounts and created a page that mimics the original for selecting an account and logging in. The phishing link is delivered from a compromised email account from ‘avis.ne.jp’ which looks like a notification for voicemail message. A button promising to provide a preview of the alleged communication is embedded in the email; when clicked, it takes the victim to the page with the captcha code. The SEG cannot proceed to and scan the malicious page, only the Captcha code site. This webpage doesn’t contain any malicious items, thus leading the SEG to mark it as safe and allow the user through.
