Abstract: Backdoors are often installed by attackers who have compromised a system to ease their subsequent return to the system. We consider the problem of identifying a large class of backdoors, namely those providing interactive access on nonstandard ports, by passively monitoring a site's Internet access link. We develop a general algorithm for detecting interactive traffic based on packet size and timing characteristics, and a set of protocol-specific algorithms that look for signatures distinctive...

.... in the SSH protocol [YKS 00a] It is easy to identify such a nested SSH connection using techniques developed by Zhang and Paxson [ZP00b, ZP00a] Hence in this case the eavesdropper can easily identify the packets corresponding to the user s password on link A B, and from...

...power of the adversary. However, we do allow occasional break ins through factors such as insecure OS, software bugs and backdoors [17], etc. When a networking node is compromised, all its information, public or private, is exposed to the adversary. These information...
