DeFi-type projects most attacked in 2022: Blockchain Security Alliance

If you have been following the crypto scene lately, it’s no secret that DeFi-related projects have been hit hard by cyber-attacks in 2022.

From the Ronin Bridge attack to the Nomad Bridge attack, the 12 cross-chain bridge incidents alone have caused US$1.8 billion in losses.

A new report from the Blockchain Security Alliance has revealed that of 167 major security incidents over the last year, DeFi-type protocols were attacked 113 times, or about 67.6% of the total attacks, making it the most frequently attacked project type.

In the report, Beosin, a leading blockchain security firm monitored more then 167 major attacks in the Web3 space, with a total loss of about US$3.6 billion from all types of attacks, an increase of 47.4% from 2021.

Of these, 10 security incidents lost more than US$100 million in a single attack and losses of 21 security incidents ranged from US$10 million to US$100 million.

Alarmingly, the report states that this trend is not likely to slow down and will continue onward into 2023.
