Hey guys,

i am looking for working guides or Users tat can help me about bruteforcing a rar-archive that is password secured. It is around 5GB Big and has a password on it. I got several options for the password, but it can also be totally different.

If you can help me with that in any case, just PM me.

You can try this 
 
Code:
 
sudo apt-get install rarcrack hashcat john


which installs hashcat and some rar utilities for a debian based os. Then, you can do this
 
Code:
 
rar2john example.rar > hash.txt

which should extract the hash from your archive. you will need to remove everything before the first : character. for example

"example.rar:$rar5$...ETC" become "$rar5...ETC"


Now try to crack it using hashcat

For example,
 
Code:
 
hashcat -m 13000 -a 0 hash.txt path/to/wordlist


 where path/to/wordlist is a wordlist like rockyou.txt. The paramter 13000 is for RAR5 hashes, However, you should check the hash.txt file to see which type of hash it is and make sure that you use the correct mode with hashcat.

hope that helps,

oh, and I also found this video on the topic if you need someone to walk you through it https://www.youtube.com/watch?v=IHoH05IMBe4
