Short description
Win32/Vedrio.A installs a backdoor that can be controlled remotely. The file is run-time compressed using UPX .
When executed, the trojan creates the following files:
  • %system%Rasmon.dll (90112 B)
  • %windir%DFS.bat
The trojan registers itself as a system service using the following name:

The following Registry entries are created:
  • [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumRoot
    "*NewlyCreated*" = 0
    "ActiveService" = "UpsWts"
  • [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumRoot
This causes the trojan to be executed on every system start.

A string with variable content is used instead of %random% .
