See "landmines" in http://www.isham-research.co.uk/dd.html
The German adjective - not very politically correct - is "getürkt". I frequently mention my dear old HP41CV in the footnotes to the MIPS tables. That's because one of the things it's used for is to find landmines. In any given set of received MIPS tables there will be one or more single-digit errors - usually caused by one or more values being truncated rather than rounded. In any other set, the "errors" are often in different places. I recommend David Kahn's Codebreakers as an elementary text - wrapped up in several good narratives are some important lessons in signal security. Paraphrasing, reformatting etc. His advice is to take as much care with the input as with the output. If HP's ruse caught anyone then it's their own fault.
