This is a category for block ciphers that have been broken. "Broken" here means that there is a published attack that is computationally faster than a brute force attack.
Note that most cryptanalytic attacks against ciphers are still too complex to apply in practice. Widely cryptanalysed ciphers like Advanced Encryption Standard are considered stronger than un-cryptanalysed ciphers even if there are impractical attacks against them.
