PACTF_2017: Remember MD5?

Category: Points: 40 Description:

Remember md5? Oh. Those good old days of md5 and huge rainbow tables. I get nostalgic just thinking about it. Well, you can’t use one of those to break my password. It still isn’t very secure though. I only used my favorite characters ‘a’, ‘b’, and ‘c’. I remember it being about 14 characters long. The hash is 1b657b7fe26eda5b3c1309d340f1674d.

Hint:

When all else fails, try brute force.

Write-up

Bruteforcing with Python!

Therefore, the flag is abbabcbabcbabcb.
