...This is the first known example of a working algebraic attack on up to 10 rounds of a real-life "industrial" block cipher. The attack requires only ONE SINGLE KNOWN PLAINTEXT (instead of a very large quantity). This is an unprecedented thing that has no equivalent in any cryptographic attack ever done...
Thus, if DES is susceptible to this kind of algebraic cryptanalysis, then probably nearly any other cipher is, and some may be substantially weaker...
