Probably hash+salt





First identify the hash just google hash identifier, you can use hashid as well. Next check out crackstation you can paste in the hashes and if they have been cracked before you will get a result. Make sure you have the actual password hash and salt (if present), I would suggest hashcat, maybe spin up a Google droplet if you don't have a good video card (Nvidia) they have some droplets with great resources.. btw bruteforcing passwords is 100% going to work, just the time frame like sometimes it might be when the sun burns out (5 billion years) before you may get a result.

Edit: It'd be nice to know where these came from, at some point you may have to use "helper" scripts to get the hashed passwd, as I look at it some don't look exactly correct.
