Exploit For Ms12-020 RDP Bug Moves to Metasploit

As the inquiry into who leaked the proof-of-concept exploit code for the MS12-020 RDP flaw continues, organizations that have not patched their machines yet have a new motivation to do so: A Metasploit module for the vulnerability is now available. 

Newly Compiled Driver Shows Duqu Authors Still At Work

The still-unidentified group of attackers behind Stuxnet and Duqu have drawn quite a bit of attention to themselves in the last couple of years with their creations. Researchers, law enforcement and some particularly angry governments all would like to have a long talk with the crew. But that attention apparently hasn’t persuaded the group that it’s time to tone down their pursuits, as evidenced by the fact that researchers have discovered a newly compiled driver for Duqu within the last couple of days.


Microsoft has a big, ugly problem on its hands. The company is caught in the middle of what’s rapidly become a major controversy centered on the leak of proof-of-concept exploit code for the MS12-020 RDP vulnerability. Many researchers, including the one who first discovered the bug and reported it to Microsoft through the Zero Day Initiative, believe that the software giant has a leak, either within its own walls in Redmond, or somewhere in its MAPP information-sharing program.

There is a confirmed legitimate working exploit for the MS12-020 RDP vulnerability in Windows circulating already and researchers say it is capable of either crashing or causing a denial-of-service condition on vulnerable machines. Microsoft has warned customers about the possibility of the exploit surfacing quickly and advised them to patch the flaw immediately. The researcher who discovered the vulnerability said that the packet he included in his original advisory was found in the exploit, raising the specter of a data leak somewhere in the pipeline.

Malware that targets Android phones has been on a steady rise for the last couple of years, and much of it has come in the form of compromised apps or outright malicious apps disguised as games or utilities. But now researchers have come across a new Android threat that is designed specifically to steal users’ online banking credentials and create persistent, silent access to the compromised handset.

Those multi-gesture passcode locks on Android phones that give users (and their spouses) fits apparently present quite a challenge for the FBI as well. Frustrated by a swipe passcode on the seized phone of an alleged gang leader, FBI officials have requested a search warrant that would force Google to “provide law enforcement with any and all means of gaining access, including login and password information, password reset, and/or manufacturer default code (“PUK”), in order to obtain the complete contents of the memory of cellular telephone”. 

Windows 8 is still off on the horizon somewhere, but the new version of Internet Explorer that’s coming with it–IE 10–already is in consumer preview and it includes some major changes to the exploit mitigations. In addition to the existing implementations of ASLR, DEP and others technologies in Windows and IE, Microsoft has included a couple of new ones designed to further inhibit memory attacks.
