More Information
Troj/Dloader-BO downloads and executes a file from the website
masteraz.hypermart.net within 3 days of being run for the first time. At the time of writing Sophos has seen examples of two downloaded files, detected as Troj/Bdoor-Aml and Troj/Keylog-I but, of course, the file could be changed.
Troj/Dloader-BO has been seen in the files MASTERAZ.EXE, JIMKRE.EXE and messages.hta.
The Trojan adds the following entry to the registry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
.inr\5Nzg1mOWKzFnuvu6 = "C:\<path to Trojan>".
This will run the Trojan on system restart.
The Trojan also creates the following entry within the registry:
HKLM\Software\CLASSES\.inr\5Nzg1mOWKzFnuvu6.
