The idea is simple.. 
1. extract Uhaha's challenge file using your favorite Uha Extractor (in this case we're using uharc) with bruteforce technique using first 100 rockyou wordlists2. extract the content of Uhaha extracted from previouse step using "Step 1"3. repeat until you extracted the flag
write simple python script ftw
```import osimport subprocess
wl = ['123456', '12345', '123456789', 'password', 'iloveyou', 'princess', '1234567', 'rockyou',      '12345678', 'abc123', 'nicole', 'daniel', 'babygirl', 'monkey', 'lovely', 'jessica',      '654321', 'michael', 'ashley', 'qwerty', '111111', 'iloveu', '000000', 'michelle',      'tigger', 'sunshine', 'chocolate', 'password1', 'soccer', 'anthony', 'friends',      'butterfly', 'purple', 'angel', 'jordan', 'liverpool', 'justin', 'loveme', 'fuckyou',      '123123', 'football', 'secret', 'andrea', 'carlos', 'jennifer', 'joshua', 'bubbles',      '1234567890', 'superman', 'hannah', 'amanda', 'loveyou', 'pretty', 'basketball', 'andrew',      'angels', 'tweety', 'flower', 'playboy', 'hello', 'elizabeth', 'hottie', 'tinkerbell',      'charlie', 'samantha', 'barbie', 'chelsea', 'lovers', 'teamo', 'jasmine', 'brandon',      '666666', 'shadow', 'melissa', 'eminem', 'matthew', 'robert', 'danielle', 'forever',      'family', 'jonathan', '987654321', 'computer', 'whatever', 'dragon', 'vanessa', 'cookie',      'naruto', 'summer', 'sweety', 'spongebo', 'joseph', 'junior', 'softball', 'taylor',      'yellow', 'daniela', 'lauren', 'mickey', 'princesa']
def test(passwd, f):    out = subprocess.run(['uharc', 'e', f'-pw{passwd}', f], stdout=subprocess.PIPE)    return out.stdout
c = 0while True:    for i in wl:        print(f'[Trying] : {i}')        cname = f'uhaha-{c}.uha'        res = test(i, cname)        if b'ERROR' not in res:            print(f'[Found] : {i}')            c += 1            os.rename('uhaha', f'uhaha-{c}.uha')            print(res)            break```
