Chainalysis reports $2B crypto hack from cross-chain bridges

A report from Chainalysis shows that $2B crypto was hacked from a cross-chain bridge this year There have already been 13 different bridge attacks in 2022, with the $190 million Nomad Bridge exploit being the most recent.

According to a recent report, cross-chain bridge hacks were responsible for 69 percent of all cryptocurrency losses in 2022, or $2 billion in losses. According to a report by Chainalysis a blockchain analytics company, there have been 13 different token bridge hacks this year, with the most recent being the $190 million Nomad Bridge flaw.

In 2022 Q1 most amounts of crypto were stolen since 2021, Ronin bridge attack in march saw $624 million in Ethereum and circle USD stolen.

Bridges between different blockchain networks, also known as cross-chain bridges, are used to transfer digital assets. Despite the fact that bridge designs can differ, according to Chainalysis, users deposit their tokens from one chain to the bridge protocol, after which they are locked into a contract. After that, the user receives what would be a parallel token in a different chain.

Bridge vulnerabilities

Bridges are frequently attacked because they “feature a central storage point of funds that back the ‘bridged’ assets on the receiving blockchain,” according to the Chainalysis report. “That storage point becomes a target,” regardless of whether the money is kept with a central custodian or in a smart contract.

Effective bridge design is still in its infancy; it’s not efficient enough, according to some experts developers still only have a basic knowledge of security protocols, leaving their systems open to hacker attacks. As a result, people don’t know how to defend against common attacks in cross-chain systems because we haven’t yet attained that level of attack expertise.

Centralized exchanges were once a favorite target of hackers, but according to Chainalysis, advancements in security protocols have resulted in a decrease in successful cyberattacks. The blockchain analytics company has emphasized the need for bridges and other cryptocurrency services to begin investing as soon as possible in security enhancements and training.
