Somebody is accusing me that my linux ubuntu machine could be the source for a server attack.
Their technique was replacing the original ssh by this patched ssh and, as such eliminated all sshd logging and debugging information while allowing any user account to be logged into when provided a special password; also, in some cases, they made links between this spurious ssh2 and the original ssh. This explains why, on , I found the ssh host key changed. Additionally, they put some other stuff in /tmp/ , /var/tmp/ , /dev/.lib1/ and /dev/shm/, /dev/.lib1/ and /dev/shm/
, /dev/.lib1/ and /dev/shm/
Any ideas if this can be possible. I didn't have other reports and I am connecting through ssh at at least a dozen other servers. how to check for sniffers in Ubuntu? how can I check if my ssh is still valid?
