When they say backdoor do they really mean virus / RAT / malware? If there is a backdoor in Linux that would be very big news. If it's a RAT [1] that's PEBKAC [2] and not a Linux Backdoor. If there is a Linux Backdoor one should be able to link to it under this directory [3].
Another day, another backdoor. At this point, I wonder if any system is actually secure, or if we just haven't found the backdoor yet.
Read the original source, it's just another malicious script that the user needs to run manually. Oh, it doesn't make use of any OS/kernel vulnerabilities either.
It's like putting "rm -rf /" in a script and calling it "malware".
