8 letters was estimating something like 2 months, but I didn't let that test finish.

(Not the same as the NTLM cracking the article mentioned, but its what I had!)Ĭould never get hashcat to run so I focused more on John the Ripper.Īt least with John the Ripper which uses your CPU any password protected zip file with a password from 0-4 letters was cracked almost instantly, 5 letter password took about 2 minutes, 6 letter password was 4-5hours and 7 letters was multiple days.

Was experimenting with John the Ripper and Hashcat just last month to see if I could crack zip and rar files that I made myself. Yet, in light of this, perhaps it's still a good idea to brush up on online security best practices, starting with storing lengthier passwords in one of the best password managers.

This means that the chances of your PC being the target of a deranged RTX 4090-owner cracking passwords at will are slim - so slim they're almost nonexistent. Additionally, the password-cracking ease of tools such as HashCat are usually deployed against offline assets, not online ones. Relax - not every RTX 4090 owner will turn their top-tier graphics card towards a password-cracking pastime. Looking at the cost decreases in password-cracking just with GPUs, however, it seems that current security should be upgraded to newer, post-quantum algorithms sooner rather than later. Of course, another chip on cybersecurity's shoulder is the amount of data that needs to be encrypted against the inexorable development of quantum computing - computers that will render almost all currently-used encryption schemes pedestrian. Jacob Egner has an extremely detailed and interesting analysis on his blogpost detailing his discoveries on the $/hash ratios. What the RTX 4090 does is bring down the cost to actually crack passwords - something that happens as long as more powerful GPUs come out while security algorithms remain relatively static. But then, that was to be expected: even a human would be extremely fast in cracking a password such as "123456" - apparently the most common password of 2021 (opens in new tab).Īnother interesting element to note is that password cracking naturally has an associated cost investing in a $1,6 is costly, and each attempt at cracking a password will incur in power costs as well.
When HashCat is driven to test the most commonly used passwords, however, it can bring a theoretical 48 minute cracking operation that attempted all 200 billion possible combinations down to the millisecond range. Of course, that assumes that the password is as least eight characters long and that it follows the required conventions (at least one number and a special character included). And they can now be taken out in under an hour by a "specialized" hashing rig. This doesn't mean that they're the least safe it just very likely means that it's the most common password character length. According to Statista and from 2017 data, 8-character passwords are the most common among leaked passwords, commanding a 32% share of them. The researchers estimate that a purpose-built password hashing rig (pairing eight RTX 4090 GPUs) could crack an eight-character password in 48 minutes.
