dumpsniffer

tools for analyzing strings from password lists

quickstart / setup

git clone https://github.com/nyxgeek/dumpsniffer.git
cd dumpsniffer;chmod +x *.sh 
./getcleanwordlist.sh

this will download cracked passwords from Troy Hunt’s public dump, via hashes.org (The wordlist source file can be changed in ./dumpsniff.conf)

once a wordlist is in place:

./popcon.sh baseball basketball football

or

./viewresults.sh hacktheplanet

overview

• this project is meant to look at one password dump (or any text file) at a time.
• If you want to start again, just rename the ./db folder to something else.
• There is a dumpsniff.conf file that contains the path to the password dump to be searched.

The search results are stored in their raw form under the following directory structures:

./db/
./db/a/
./db/a/aardvark.out.txt
./db/a/awesome.out.txt
./db/b/bitcoin.out.txt
./db/c/computer.out.txt
...

Using the filesystem to hold data was chosen over a traditional db because this allows the easy viewing and editing of the results. This allows you to manually parse and remove false-positive results using tools like ‘grep’.

createregex.sh

usage:
./createregex.sh file.txt > file.regex
Read line "testing":
[tT+7][eE3][sS$5][tT+7][iI1!|][nN][gG69]

give this script a file with one word/phrase per line and it will convert output it as leetspeak regex

This can then be used with grep in the following manner:

grep -E -f file.regex file_to_search.txt

getcleanwordlist.sh

usage:
./getcleanwordlist.sh

That’s it. It downloads and cleans the wordlist a little (trims lines longer than 24 char and removes non-ASCII).
