Code Review for Backdoors

1. Author Yiannis Pavlosoglou

The review of a piece of source code for backdoors has one excruciating difference to a traditional source code review: The fact that someone with 'commit' or 'write' access to the source code repository has malicious intentions spanning well beyond their current developer remit. Because of this difference, a code review for backdoors is often seen as a very specialised review and can sometimes be considered not a code review per say.

A traditional code review has the objective of determining if a vulnerability is present within the code, further to this if the vulnerability is exploitable and under what conditions. A code review for backdoors has the objective to determine if a certain portion of the codebase is carrying code that is unnecessary for the logic and implementation of the use cases it serves.

Further to this, the reviewer, looks for the trigger points of that logic. Typical examples include a branch statement going off to a part of assembly or obfuscated code. The reviewer is looking for patterns of abnormality in terms of code segments that would not be expected to be present under normal conditions.

An excellent introduction into how to look for rootkits in the Java programming language can be found here. In this paper J. Williams covers a variety of backdoor examples including file system access through a web server, as well as time based attacks involving a key aspect of malicious functionality been made available after a certain amount of time. Such examples form the foundation of what any reviewer for back doors should try to automate, regardless of the language in which the review is taking place.
