Since July 12, four unnamed American Internet Service Providers (ISPs) have been hacked. They all used the same platform to manage and control their vast networking enterprise. By infiltrating this platform, hackers managed to steal customer credentials, which were otherwise encrypted.
Black Lotus Labs first discovered and reported the vulnerability in Versa Director (the platform these four ISPs were using) two days ago. The researchers identified the first exploitation of this vulnerability dating back to June 12, 2024, and it was only patched on August 26, 2024.
The attackers hijacked small office and home office routers to enter Versa Director systems. They were able to penetrate Versa’s systems because of an exposed port (which should have been protected by a hardened firewall, but the affected ISPs didn’t follow Versa’s instructions). The threat actors used this entry point to inject a malicious java file called “VersaMem.” That’s where the bug was: the file upload system which should have sanitized this file. This code gave them admin access to the entire Versa Director dashboard.
