Abstract

On 16th of May, Sean Sullivan has published an article on F-Secure blog about a new Mac OSX malware discovered on the Mac of an African activist by Jacob Appelbaum during an Oslo Freedom Forum workshop.

According to file Unix command, this binary is a Mach-o executable containing x86 and x64 code. VirusTotal repport of this binary can be found here. With a really quick look at the sample, we can see that it is not packed, obfuscated or encrypted.

This sample contains two C&C url which in fact are at the moment pointing to the same server at IP 50.116.28.24 (This differs from F-Secure blog post, where IP addresses of both domains where different). This IP address points to Linode hosting company.
