On February 22, the founder of Slow Mist, Cosine, posted on social media that from a security perspective, the suggestion to urgently stop the wallet system in the case of unknown reasons is correct. Bybit's theft response speed is extremely fast, and the positioning problem is also extremely fast. SlowMist and some security teams immediately intervened in the communication, quickly identified the problem and speculated on the hacker portrait. Bybit was ready and then opened the withdrawal in time. Cosine explained that it believed that CZ's previous suggestion and Bybit's final solution were fine. At present, many people in the industry are fighting this controversy internally, but they forget that the common enemy should be North Korean hackers.
