Particular Case of RAR Password Cracking

[niculaita]

1. just simple: ask password from owner you should have 50 % chance

2. passware 1.1 see https://rutracker.org/forum/viewtopic.php?t=5381706
or 4.0 https://dailyuploads.net/7a7g0uqj2xmh for that maybe someone share a good new serial for 2017.4.0

3. AccentRPR 3.5 build 3415 x64 http://sendfile.su/1287496 that works on windows 7 x64

P.S. here is not free databases: https://www.4shared.com/office/fqQqWxKPba/0all_about__dictionary_with_mo.html

Use free tools, they are more flexible
First use rar2john from John The Cracker jumbo package to get the hashes. With the hashes listed in a file you can start cracking them with john or hashcat .
In your case the "Wordlist + Rules" option is needed: c Capitalize the first letter and lower the rest
Google for a good dictionary or use those from SecLists.

Regarding "50% of the files contain a file which name contains this password.", you can create a list of them using easy bash script like:

for i in $(ls | grep .rar); do unrar l $i | grep "*" | awk '{ print $6}'; done

thankyou everyone.

I'm going to study the situation and decide what is best based on your kind suggestions.

I'll let you know what's going on.

@niculaita: do you believe that if 1 was applicable, i'd have written that long paragraph on this forum?
