Thanks to CTOnews.com netizens MissBook and assassin for the clue delivery! CTOnews.com, October 8 news, in the early morning of October 7, Beijing time, the intelligent contract Taiwan dollar chain (BNB Chain) suffered two attacks one after another (2:26 and 4:43). Hackers ransacked 2 million AND BNB in just 2 hours, and the value of this currency alone reached US $566 million. Plus other virtual assets of about US $718 million, if the subsequent impact is taken into account, the amount involved can reach about US $850 million. Independent analysts at CIAOfficer said the amount was the largest chain attack in history.

According to the public information, BNB Chain is one of the most active public chains incubated by the world's largest cryptocurrency exchange currency (CTOnews.com popular science chain: public chain is a chain of consensus blocks that anyone can read, send transactions and obtain valid confirmation).

At around 6: 00 a.m. on the same day, BNB Chain officials said: due to abnormal activity, it is currently under maintenance, suspending all deposits and withdrawals through the BNB chain until further updates. At the same time, it is indicated in another development that about US $70 million to US $80 million has been withdrawn and US $7 million has been recovered (frozen).

Subsequently, an CEO Zhao Changpeng, who was once called the "richest man in China", tweeted that the current damage was estimated at US $100 million. He apologized to investors and said he had recovered some of the money. Yuan an stressed that the currency exchange itself has not been attacked or suffered losses. At the same time, Yuan an has also suspended investor recharge and withdrawal functions.

"the problem is now under control. Your funds are safe. We apologize for the inconvenience caused to investors and will provide further system updates in the future."

Zhao Changpeng pointed out that the thieves made use of a loophole in the cross-link bridge "token center" BSC Token Hub to invade, and he assured customers that the loophole had been repaired. Simply put, a cross-link bridge is a tool for investors to transfer assets from one blockchain to another.

It is worth mentioning that Tether, the parent company of USDT, has blacklisted the hacker address, which also holds more than $45 million worth of ETH.

In fact, hacker attacks have occurred from time to time this year, such as the theft of Axie Infinity in March, the theft of cryptocurrency company Nomad in September and the theft of more than $600 million in assets by hackers in Cross-Link Bridge, which are all related to the vulnerability of Cross-Link Bridge. Chainalysis, an encrypted asset analyst, previously pointed out that cross-link bridge hacker attacks accounted for 69% of hacker attacks, and cross-link bridge vulnerability attacks have resulted in about $2 billion stolen this year.
