Technical Information

To ensure autorun and distribution:

Modifies the following registry keys:

[<HKLM>\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] 'aeEkEEcE.exe' = '%ALLUSERSPROFILE%\BWogoUMg\aeEkEEcE.exe'
[<HKCU>\Software\Microsoft\Windows\CurrentVersion\Run] 'pUccUkoM.exe' = '%HOMEPATH%\fCkYUMIQ\pUccUkoM.exe'

Malicious functions:

To complicate detection of its presence in the operating system,

forces the system hide from view:

hidden files
file extensions

blocks the following features:
