According to ChainCatcher, Bitcoin core developer Luke Dashjr tweeted that his PGP (Pretty Good Privacy) private key was leaked, resulting in the theft of almost all of his Bitcoin. According to on-chain data, Luke Dashjr's wallet address made four transactions on December 31, transferring 216.93 BTC, which is worth about $3.5 million at current prices.

It is reported that PGP is the first widely used encryption software to implement public key cryptography. It is a hybrid cryptographic system architecture that uses symmetric encryption and asymmetric encryption to achieve high-level security. Binance founder Zhao Changpeng left a message saying that he would cooperate with the investigation and had notified the Binance security team to monitor it. At the same time, he reminded users that "self-custody has various risks." (Source link)
