The multi-chain wallet BitKeep announced in a Telegram group that the cause of this large-scale hacker attack has been found, and it is an extremely bad group theft incident. The BitKeep APK package downloaded by some users was hijacked by hackers, and the wallets used by users are no longer the official version. Now the hackers have transferred most of the funds to the wallet address on BNB Chain. BitKeep calls on BNB Chain and Binance officials to help freeze the hacker address and stolen funds.
