Chainalysis estimated the damage from hacking cross-chain protocols since the beginning of the year
According to Chainalysis, the first quarter of 2022 was one of the most profitable for hackers in terms of stolen funds. So, at the end of March, the inter-network bridge of the Ronin blockchain was attacked, during which the attackers withdrew $624 million in ETH coins and USDC tokens.
This type of hack accounts for 69% of all stolen crypto funds this year, according to analysts at Chainalysis. Cross-chain bridges are used to send tokens between blockchains and are a popular tool used by the crypto community.
The last such episode was the August 2 hack of the Nomad protocol in the Evmos ecosystem.
Analysts note that hacker groups linked to the North Korean government are actively involved in stealing cryptocurrencies. Cybercriminal groups managed to gain control over $1 billion worth of assets, including as a result of attacks on bridges.
