DefiLlama: Crypto hacks comprise $7.7b in losses since 2016

Crypto hacks have cost the digital asset industry billions of dollars, with experts advising additional attention and resources toward security measures.

According to DefiLlama, all-time losses incurred from crypto hacks exceeded $7.7 billion as of April 1, despite a 23% decrease in incidents during the first quarter of 2024 compared to last year. Data revealed that decentralized finance protocols lost the most money since 2016, with hackers having stolen $5.8 billion from defi in seven years.

Platforms that enable users to transfer assets between blockchains, commonly called bridges, account for over half of defi hacks. Exploiters looted $2.8 billion from these solutions through several attack vectors inherent in smart contract loopholes.

Per DefiLlama, private key compromises, access control exploits, proof verifier bugs, signature exploits, and flash loan price oracle attacks ranked as the five most popular methods for crypto hacks. However, 42% of all incidents remain unaccounted for, so experts are unsure how attackers orchestrated nearly half of all hacks.
