[en] Urausy ransomware get an update and taunts antivirus

Today, i notice an update from Urausy ransomware (sample http://malwaredb.malekal.com/index.php?hash=5ffcea540f262d5a20165a03a9b11dfa).
Previous version used the file msconfig.dat now it uses the file skype.dat

and of course the skin is updated adding some informations (IP, Country, Username) and also a “Protected by” sentences with an image.
In the first case, the image is empy (I don’t have any antivirus installed on my VM).

 

so i try with Avast! and Antivir and the logo appear.
a bit ironic ! isn’t it ?
