Hash analysis specify a list of MD5s finding several known bad files, – files from a rootkit – illegal images the MD5s that compose file (KNOWN.BAD) of already known files such as – f53ce230616c1f6aafedf546a7cc0f0f Trojan ps – bbf3aeb654477c4733bddf9a6360d2c5 Illegal Image run md5deep against all of the files in the directory It compares the file’s hashes with the contents of the list of known hashes. If a match occurs, it lists it on standard out
Finding Files by Type and Keyword Searches # find / -type f \( -name ‘*.gif’ –or –name ‘*.jpg’ –or –name ‘*.bmp’ –or –name ‘*.png’ \) # grep –i –r –f keywords /image/* > /evidence/grep.results – i - case insensitive search, thus ‘cocaine,’ ‘COCAINE.’ and ‘CoCainE’ – r - a recursive search, i.e., traverse all of the subdirectories beneath the current directory. – f - the next parameter is the file containing our keywords.
