When I used to work for Sun on incident response, Sun maintained a  
MD5 repository (and they may still do so today), of all the known  
binaries released by Sun. The idea was, you could do an automated  
check on a system, looking for Sun binaries that did not match any  
known signatures.  Based on this model, an easy way to create a  
backdoor would be to simply replace a current binary/file with  
another known/valid file, but one that is much older and with known  
vulnerabilities.
