#Security: Phishing with Macros once again!
Hacking | 2 min | 1192
And once again! Word files with Macro! But this time, I was the first one to report it to VirusTotal and Hybrid-Analysis! :)
Fig 1: VirusTotal report! Just only two: Fortinet sells hardware, and Qihoo-360 is in China (:S)...
Here you have the e-mail. The sender is this time the "BOSS Last Name" (A nice improvement! :P) without address, or something like that!

firstname.lastname@example.org. Sorry randy, I published your e-mail! The auth is still PLAIN! I do not understand this!. Here you can see the logs:

Here you have the analysis of the files:
The analysis by Hybrid-Analysis is quite interesting! They were able to catch the host server:
Contacted Hosts IP Address Port/Protocol Associated Process Details 188.8.131.52 OSINT 80 TCP powershell.exe (PID: 3752) Slovakia (SLOVAK Republic) 184.108.40.206 8080 TCP storagewmi.exe (PID: 3036) Hungary
The standard correction language of the file was set to russian language.
As usually, I wrote 'elprofedemicurso' and I sent the files to the Antivirus companies. Avira still does not recognize the file as a VIRUS!!! :( .
I've read somewhere that they are using ObfuscatedEmpire to obfuscate the files. There are little chances for the Antivirus to detect a new variant of this type of files. That means, I am going to receive more e-mails like this one, or I should I have to tune the Spam filter! Do you have an idea how can I filter this type of e-mails using Exchange 2010?!. Please write me a comment, if you known that! Thanks in advance!!!
