2022 biggest year ever for crypto hacking, report says

More than $3B was stolen from cryptocurrency businesses last year

Last year was the biggest year ever for cryptocurrency hacking, according to a new report. 

Chainalysis, a software company, said Wednesday that $3.8 billion was stolen from cryptocurrency businesses in 2022.

October became the biggest single month for cryptocurrency hacking, as $775.7 million was stolen in 32 separate attacks. North Korea-linked hackers, such as those in the cybercriminal syndicate Lazarus Group, drove much of the activity and shattered its own annual record for the most cryptocurrency stolen.

In 2022, the group stole an estimated $1.7 billion worth of cryptocurrency across several hacks Chainalysis attributed to it. Of that sum, $1.1 billion was stolen in hacks of decentralized finance (DeFi) protocols. A DeFi protocol is a set of codes that govern how digital assets are used on a blockchain network, according to The Defiant.

In 2021, DeFi became the primary target of hackers, which only intensified in 2022.

DeFis protocols as victims accounted for 82.1% of all cryptocurrency stolen by hackers, up 73.3% from the previous year.

Of that, a total of $3.1 billion came from cross-chain bridge protocols specifically. Chainalysis said that cross-chain bridges are protocols that let users port their cryptocurrency from one blockchain to another, often by locking the user’s assets into a smart contract on the original chain and minting equivalent assets on the second chain. 

However, the report notes that law enforcement and national security agencies' ability to fight back is growing.
