#tmesis will take a wordlist and produce insertion rules that would insert each word of the wordlist to preset positions.
#For example:
#Word ‘password’ will create insertion rules that would insert ‘password’ from position 0 to position F (15)  and It will mutate the string ‘123456’ as follows.
#password123456
#1password23456
#12password3456
#123password456
#1234password56
#12345password6
#123456password
#
#Hints:
#*Use tmesis to create rules to attack hashlists the came from the source. Run initial analysis on the cracked passwords , collect the top 10 – 20 words appear on the passwords and use tmesis to generate rules.
#*use tmesis generated rules in combination with best64.rules
#
# inspired by T0XlC
