I was recently checking for suspicious activity on my mail server and found 5 rather large files, (roughly 300 meg each) in my /var directory. They have an old timestamp but I do not remember seeing them before.
The only text inside of these files is ioutbkuytbv over and over with newlines.
Is this some form of rootkit script kiddy crap? Has anyone else seen this before?
What was the name of the file? Google for the name and content, maybe you will find something.
Check with rkhunter if it can detect any rootkits. If you do find information about this, you should post it and share it with us.
