More Information
Troj/Krepper-M is a downloading Trojan for the Windows platform.
Troj/Krepper-M copies itself to a subfolder of the Windows system folder named "services" and creates the following registry entries to run itself automatically on log-on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
xpsystem
<filename>
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
xpsystem
<filename>
HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows\
run
<filename>
Troj/Krepper-M also adds the following entry to the System.ini configuration file to run itself automatically:
[Windows]
load = <filename>
(where <filename> is the full path to the Trojan executable)
Troj/Krepper-M downloads several configuration files from preconfigured URLs. The contents of these files determine how the Trojan behaves next. They can instruct it to:
download more files
create registry entries
execute arbitrary commands
add domains to the "trusted" list
open specific URLs in Internet Explorer
