Subject: [Full-disclosure] interesting trojan found
A client had a problem home PC, after removal of all the usual spyware, adware
and 6 month old viruses,
there remained an unusual process in the process list, logon.exe, which
Process Explorer pointed to it being from c:\windows\system32\logon.exe
it tries to connect to a singnet ip address on port 3175.
This file appeared almost invisible to the file system in both safe & normal
mode, which struck me as being unusual.
You could not delete it, copy it or see it in a directory listing (file not
found), but you could execute it directly.
I eventually got a copy of it by using an NTFS-reader boot disk, and ran it
through virus total.
Kaspersky was the only one to recognize it as backdoor.win32.rbot.gen
Just wondering really
a: if anyone wants it for study. (off list replies pls, will be sent in
b: anyone know a free boot disk that both reads & writes to NTFS, so I can
