Cracking ethereum wallet password - g-t - 12-20-2017 Hi, I've been trying to recover my friend's ethereum password. As far as I know him I suspect it can't be very difficult password. I've downloaded latest hashcat version which should support ethereum wallet (scrypt) password cracking (mode 15700). I was trying to run it on gpus (6x radeon 580 mining rig) but it hangs the machine completely. I also read some articles about scrypt and it turns out that for n=262144 gpu cracking shouldn't work so I decided to try old-school cpu cracking. I can see my cpu in hashcat: Code: hashcat-4.0.1 ./hashcat64.bin -I I'm trying to run cracking like that: Code: ➜ hashcat-4.0.1 ./hashcat64.bin -m15700 "\$ethereum\$s*262144*8*1*1ebcc...bdd12f*4e065...5af0366*f86586319...8df" --status --status-timer=5 -w3 --opencl-platforms=3 but the app constantly prints: Code: Session..........: hashcat I was also wondering if something's wrong with my computer that runs Fedora Core but the same happens on two different computers with Windows 10. Another weird thing is benchmarking. I ran hashcat64.bin --benchmark and everything went fine but didn't benchmark mode 15700. I can see 15600 but 15700 is missing. Code: Hashmode: 15600 - Ethereum Wallet, PBKDF2-HMAC-SHA256 Here's part of wallet.json: Code: "crypto": { Am I doing something wrong ? Would appreciate any help. RE: Cracking ethereum wallet password - undeath - 12-20-2017 first, do not post hashes. second, you are not specifying an attack mode and corresponding settings, hence hashcat defaults to stdin mode with a0.

Just thought it defaults to brute force. By the way could you recommend some brute force settings in such case ? Is it really impossible to use gpus ? RE: Cracking ethereum wallet password - undeath - 12-20-2017 If you don't specify a mask hashcat will use a default one which is probably not what you want. Anyway, cracking such a wallet with bf is near impossible unless the password is very short (and you know that). |
