Subject: sshd.exe infected with IDP.Generic?
Date: Fri, 10 Jul 2020 12:01:16 -0700 [thread overview]
Message-ID: <14cda058-251c-21f2-e153-edf37ef9ef91@raelity.com> (raw)
On Win7. To get an elevated shell, I typically do "$ ssh xxx@yyy". And
not very often.
Below is an excerpt of something potentially horrible that just happened.
Note the
rm *
I exited the shell. I did the "ssh..." again (yeah I'm crazy), in a
different bash window. And this time avast reported that it stashed
sshd.exe into the virus chest.
I'm not sure who/what the culprit is, or what's going on. But it does
look like there was (is?) some kind of infection somewhere on my system.
I had used ftp earlier to put a file to a remote, but...?
I didn't realize that netstat was a windows command (not that I wouldn't
have used it).
I've got the sshd.exe file. It has a date of Feb 18. So
* Can I check if the bits in sshd.exe are as expected?
* Any suggestions on cleaning up and/or restoring sanity? (I'm running
a full virus scan right now, should be amusing...)
* How can I get sshd.exe back? Is there a cygwin command to check that
the packages are all as they should be?
