Misconfigured Server Reveals Three Evilginx Phishing Operations Targeting Microsoft 365
Overview
A misconfigured Python web server used in a phishing operation targeting Microsoft 365 was discovered by Lexfo, a French cybersecurity firm. The server was left publicly accessible with directory listing enabled, allowing researchers to access a log file that contained the command used to run the server. This oversight led them to uncover not only the phishing toolkit but also two additional related operations. The exposed setup raises concerns about the security practices of attackers, as it can lead to further exploitation of users unaware of these phishing attempts. Organizations using Microsoft 365 should be vigilant and ensure their security measures are robust against such phishing schemes.
Key Takeaways
- Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
- Affected Systems: Microsoft 365 users
- Action Required: Users should implement multi-factor authentication, regularly review security settings, and educate employees about phishing tactics.
- Timeline: Newly disclosed
Original Article Summary
An attacker running a live Microsoft 365 phishing operation left a Python web server listening on a public port with directory listing switched on. The command that did it: python3 -m http.server 8080, was still sitting in the readable .bash_history. From that one lapse, French security firm Lexfo lifted the operator's entire toolkit and pivoted through it to two more
