QUOTE: Last week, we wrote about a script-based malware targeting Mac users. Yesterday, the folks from avast! revealed a Windows version.  On Friday, July 12th a warning from an AVAST fan about a new polymorphic multisystem threat came to an inbox of AVAST. Moreover, an archive of malicious files discussed here were attached. Some of them have been uploaded to Virustotal and therefore they have been shared with computer security professionals on the same day. A weekend had passed by and articles full of excitement about a new Trojan for MacOs started to appear on the web. We decided to make a thorough analysis and not to quickly jump on the bandwagon. The key observation is that the final payload comes in the form of scripts needed to be interpreted by Windows Script Console resp; Python in the case of MacOs. Moreover a script generator that creates new malicious Windows file shortcuts was also included.
