This week’s whipsaw market movements test NFT traders’ resolve — What’s next?

NFT prices take a hit alongside the sharp correction in the crypto market and only time will tell whether the current downturn was a buying opportunity.

Crypt-analysing modified AES algorithm with no shift-rows, and no key-expansion

I came across an answer about consequences of AES without any of its operation In the question in the given link, it is mentioned that “if Shift Row is removed, then attacker can treat input block ($128$ bits) as $4$ independent $32$ bits block. Hence, attacker can attack these $4$ blocks one by one to ::Listen

I came across an answer about consequences of AES without any of its operation In the question in the given link, it is mentioned that “if Shift Row is removed, then attacker can treat input block ($128$ bits) as $4$ independent $32$ bits block. Hence, attacker can attack these $4$ blocks one by one to recover key.” I did not understand this statement. I request the community to please help me understand this question.

Since AES is block cipher, we have to encrypt each 16byte block at once, but how can we divide that 16byte into blocks of 4 bytes? If I have a plaintext-ciphertext pair of 16bytes, will it be enough to recover the key? If yes, then how?
