SophosLabs has seen proof-of-concept code on Chinese websites which tries to exploit the recently announced Microsoft RDP vulnerability, causing computers to crash.
The critical vulnerability exists in Windows, and could be exploited to spread a worm automatically between vulnerable computers.
The advice from Microsoft and Sophos is to patch your copies of Windows as soon as possible, and Microsoft warned earlier this week that it expected malicious hackers to exploit the flaw within 30 days.
Well, that’s already happening. The code we’ve seen – in the form of Python scripts – attempts to exploit the MS12-020 RDP vulnerability and causes Windows computers to blue screen. It wouldn’t be a surprise if whoever is writing this code to further develop the attacks to produce a fast-spreading internet worm.
Sophos is adding detection of the script we have seen as Troj/PyRDP-A.
Fake exploits for the Microsoft RDP vulnerability
Meanwhile, we have also seen what claims to be the Python script of a worm that exploits the RDP exploit.
The script, however, appears to be a hoax. It references a Python module that doesn’t exist (FreeRDP), and claims to be written by firstname.lastname@example.org, an obvious reference to the high profile Anonymous hacker who was recently revealed to have been secretly working for the FBI for months.
The code doesn’t exploit the MS12-020 vulnerability.
