The second quarter of 2026 has seen an unprecedented number of hacking incidents in the cryptocurrency industry, with 83 exploits targeting various protocols. According to analysis by Unfolded based on DefiLlama data, this quarter is already the most-hacked quarter on record.

The total value lost so far is $755.3 million, significantly lower than the $3.56 billion lost in the fourth quarter of 2020, which remains the costliest quarter on record for crypto hacks.
