Ronin Cross Chain Bridge, a game public chain, is suspected to have suspended operations due to a &q

According to CoinDesk, the cross chain bridge of the gaming public chain Ronin suspended operations on Tuesday (6th) due to the platform being stripped of $9 million worth of tokens in an apparent white hat hacking attack.

Aleksander Larsen, co-founder of Ronin developer Sky Mavis, stated on social media:

While the operation of Ronin Bridge has been suspended, we are investigating a report from white hat hackers regarding potential MEV (maximum extractable value) vulnerabilities, and we will provide more information soon. The cross chain bridge currently protects over $850 million, and these assets are secure.

According to SlowMist, a cybersecurity company, the reason for the Ronin cross chain bridge vulnerability this time is that the weights were modified to unexpected values, allowing funds to be extracted without any multi signature threshold checks. Another security company, Beosin, has also released an analysis of the incident.

After the news of a vulnerability in Ronin's cross chain bridge came out, the price of its native token RON briefly fell by about 5%, and before the deadline, its trading price had rebounded to $1.4.

Ronin is an Ethereum sidechain network built by Sky Mavis, the developer of the memory blockchain game Axie Infinity. In March 2022, Ronin Cross Chain Bridge lost over $600 million in funds due to a hacker attack, with the Lazarus Group, which is reportedly involved in North Korea, being the mastermind behind it.
