Re: ELF_SSHSCAN.A and ELF_PORTSCAN.A

Not sure that these are viruses. I think they are part of a root-kit
that scans the internet for ssh servers that have bad passwords. I
would consider your RH box to have been compromised somehow until
proven otherwise. The usual suspects would be:

a) the box has guesable passwords that the ssh automated root scanners
found and opened up the box.
b) the box has an unpatched external facing binary that a hacker was
able to take advantage of (HTTP, SSH, email, cgi scripts?) and was
able to upload these onit
