Re: ssh trojaned

since OpenSSH sits on the OpenBSD server, has anyone else checked the sigs of any of the obsd stuff?




* Ron DuFresne (dufresne () winternet com) tapped away like a .......:

Your safest bet is going to be to get new clean source, it's supposed to
have been updated today and recompile and push it out.  The trojaned code
is supposed to have hit the openssh site withn the last 2-3 days, limiting
the exposure to only those that in that time frame scarfed up the trojaned
code.  Analysis of the trojaned codes seems to indicate this nasty runs in
the background all the while the trojaned sshd is up, so, I would get new
source and recompile and push.  Far better to be safe than sorry.

Thanks,

Ron Dufresne

Hello,

I'm no programmer so I'm hoping someone can confirm this for me..
I am correct in thinking the trojan currently in OpenSSH portable 3.4p1 only
runs during compilation ?

ie a copy of ssh compiled using this source will not have anything nasty
build into it ?

Thanks,
Steve.

OK, so you're a Ph.D.  Just don't touch anything.
