Hi,
Did anyone find the solution for this issue, I am too facing the same on my 3 servers at a time. Very strange issue. And along with that javascript insertion on all websites on those servers. Kindly respond if anyone has the solution for it or anyway to stop this from happening after new install....

strace as unprivileged user show one system call to 'sysinfo()' with the argument of '0'. It returns an error:

---
[badfile@host evil_mount]$ strace ./mount
execve("./mount", ["./mount"], [/* 22 vars */]) = 0
sysinfo(0) = -1 EFAULT (Bad address)

Going to look further into the binary from an analysis workstation I have setup and see if I can get any more information.

Cheers,
