Can someone explain succinctly what the backdoor does? Do we even know yet? The backdoor itself is not a payload, right? Does it need a malicious archive to exploit it? Or does it hook into the sshd process to listen for malicious packets from a remote attacker?
The OP makes it sound like an attacker can send a malicious payload in the pre-auth phase of an SSH session - but why does he say that an exploit might never be available? Surely if we can reverse the code we can write a PoC?
Basically, how does an attacker control a machine with this backdoor on it?
