CryptoQuant CEO: If private keys could be inferred from addresses, "besides North Korea's Lazarus, no one could do it."

Regarding the theft of approximately 44.5 billion won (about 36 million USD) in cryptocurrency assets from Upbit, CryptoQuant CEO Ki Young Ju stated today that the attack method disclosed by Upbit is "almost impossible for an ordinary hacker to execute."

Upbit previously mentioned that the attackers might have "inferred the private keys" by analyzing the patterns of user wallet addresses. Ki Young Ju bluntly said that the difficulty of such attack techniques is extremely high, and if this is true, "I suspect that no hacker organization other than North Korea's Lazarus could achieve this."
