I'm new to computer security but I'm trying the same to make a toggle case attack starting from a dictionary password.
I read there that it's possible to alternate uppercase and lower case word starting from a dictionary to have all combinations (case sensitive).
I don't know what command to use and 4 now I'm stopped on standard dictionary attack
sudo hashcat -m 16800 convertedpcap.16800 dict.txt
Someone knows howto?
Here the complete help (I removed - [ Hash modes ] - to preserve space):

Thankz
Download toggle5.rule from the Hashcat repo on Github and try running this:
sudo hashcat -m 16800 -r toggle5.rule convertedpcap.16800 dict.txt
That older togglecase example links to a newer article recommending rules be used, specifically the examples in rules/. For this example, let's use toggle5.rule, which the site explains "include[s] all possible toggle-case switches of the plaintext positions 1 to 15 of...5 characters at once".
Let's try cracking the md5 of the string HaShCaT
and put that in our example.hash
file (it's 41e24266141b6ef98bf0e1fb54b238a1
) and use a dictionary of just the string hashcat
for example.dict
file. Go ahead and create these two files in whatever folder you're working in, with whatever editor you prefer.
If we just use a normal dictionary attack, like so:
hashcat -a 0 -m 0 example.hash example.dict
It fails to crack the hash. No surprises there. Now add the --stdout
flag.
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict
You will see the hash printed followed by all candidates that would be tried if we were trying to crack a hash, which in this case is just the string hashcat
. Note, no need for example.hash in the command when using --stdout
.
Now let's try adding the toggle5.rule into the mix with
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict
I've copied the rule directly from the Github repository. Thanks to --stdout
this should print a lot of variations on hashcat
. We can make it a bit more manageable by piping it into less
or better yet...
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict | sort | uniq -c | sort -rn
Basically this will display the number of times each variation of hashcat
would be generated as a candidate. Now you can see how a rule generates new candidates for trying to crack hashes! And with that, the final run...
hashcat -a 0 -m 0 -r toggle5.rule example.hash example.dict
And success! It cracks the md5 hash HaShCaT
.
Speaking specifically to what you asked about, you might not need all the variations that toggle5.rule
gives. If you know for certain that the password you're trying to crack is less that 15 characters or it won't have more than 4 uppercase characters, you can cut down on the variations.
For example, if you only wanted to try candidates with alternating cases for every letter, your rule file would just be
T0T2T4T6T8TATCTE
T1T2T5T7T9TBTDTF
Reusing hashcat
as the example, this would generate the candidates HaShCaT
and hAsHcAt
. Just in case this is closer to what you're looking for. Feel free to describe your specific scenario in a comment and we can work together on what rules might make the most sense.
