Encryption algorithm Rivest Cipher 4[370][371][372][373] is a stream cipher[182][183] that is more malleable[134] than a block cipher[78][79][80][81]. It has multiple vulnerabilities[375][376][377][378][379] (eg: related-key attack[68], distinguishing attack[60], ...), so attacker can apply statistical analysis against it to recover the encrypted text.
