Submission + - The 2015 Underhanded C Contest has begun (underhanded-c.org)

Xcott Craver writes: The 8th Underhanded C Contest is now underway. The goal of the Underhanded C Contest is to write C code that is as readable, clear, innocent and straightforward as possible, but which performs some malicious function that is not obvious from looking at the source code. This year's challenge is based on a real problem in joint development for nuclear treaty verification, and the prize is $1000.

Submission + - The 7th Underhanded C Contest is Online (underhanded-c.org)

Xcott Craver writes: The 7th Underhanded C Contest is now open. The goal of the contest is to write code that is as readable, clear, innocent and straightforward as possible, and yet somehow exhibits evil behavior that cannot be seen even when staring at the source code.

The winners from 2013 are also online, and their clever and insightful submissions make for fun reading.

Submission + - 2008 Underhanded C Contest officially open (xcott.com)

Xcott Craver writes: "The 2008 Underhanded C Contest has just opened. Every year, contestants are asked to write a simple, innocent, readable C program that appears to perform an innocent task — but implements some nonobvious evil behavior. This year's challenge: redact blocks from an image, but do it so that the excised pixels can somehow be retrieved.

We also have listed the winners of last year's contest, which was to write a simple encryption utility that mysteriously and undetectably fails between 1 percent and 0.1 percent of the time. The winning entry is truly impressive."
