Nepalese government websites compromised to serve Zegost RAT

Posted: 08 Aug 2012 10:36 AM | Anonymous | no comments


The Websense® ThreatSeeker® Network has detected that two Nepalese government websites, the National Information Technology Center (NITC) and the Office of the Prime Minister and Council Minister (nitc.gov.np and opmcm.gov.np respectively), have been compromised and injected with malicious code that tries to exploit the Java vulnerability CVE-2012-0507. The aim of this injection is to install, through successfully exploiting that Java weakness, a backdoor that is also dubbed "Zegost" on the systems of visitors to these websites.


This vulnerability (CVE-2012-0507) was also used in the Amnesty International UK website compromise and in the INSS website compromise that we reported a few months back. It's interesting to note that all those compromises had injected code that was taken from the Metasploit framework, served in clear form, and not obfuscated. Although the use of code from the Metasploit framework doesn't necessarily indicate a link between all the compromises, we found further common characteristics between the compromises of the Amnesty UK website and the Nepalese government website by analyzing the backdoor C&C points when we noticed that they connected to the same domain in China.
