| There's a new video codec being offered that
| claims to offer up to 40% better compression,
| but in fact is adware which can download and
| install files, changes your DNS configuration,
| and monitors adult websites. Downloaded files
| can include the Trojan Ruins.MB, which
| conceals itself using rootkit techniques.

It is produced by the SAME 'codec' guys who are creating the ZLob Trojan installers that are
disguised as Video Codecs.
The files that come from them are named such as...
dvdcodec1000.exe
ZCodec1000.exe
The ZLob installers will have names like...
sv-codec-v4_01a.exe
mediacodec-4.207.exe
intcodec-v6.535.exe
intcodec-v6.107.exe
The numbers in the above will vary be will be the same. Today intcodec-v6.535.exe and
intcodec-v6.107.exe will have the same MD5 checksum and will install a new ZLob variant but
Tomorrow, they will habve a new MD5 checsum and install a new ZLob variant.
Kaspersky calls the the one that are DNS Changers "Trojan.Win32.DNSChanger"
New variants are being created on a regular basis just like the ZLob Trojans.
I will also note that the files dvdcodec1000.exe and ZCodec1000.exe can change between a
ZLob installer and a DNS Changer.
The last time I tested "ZCodec1000.exe" I got Trojan.Win32.DNSChanger.xx where .xx was the
variant which I didn't keep a record of.
This is Tonite's test...
