Blockaid Reports 212 Onchain Exploits Stole $1.1B as AI and Wallet Attacks Accelerate

Security firm Blockaid has revealed that the first half of 2026 marked the most active period for onchain security threats on record, with 212 high-threshold exploits verified—a 3.4-fold increase over all of 2025. These attacks resulted in a staggering $1.1 billion stolen, with North Korean hackers responsible for $600 million of the pilfered funds.

The acceleration of attacks using artificial intelligence and wallet vulnerabilities is reshaping the blockchain security landscape. Blockaid's report highlights a concerning trend of increasing sophistication among cybercriminals, requiring crypto investors and users to strengthen their security measures. The cryptocurrency industry faces a growing challenge to develop effective defense solutions against these evolving threats.

The report details how artificial intelligence is increasingly being used to automate and refine attacks, enabling cybercriminals to identify and exploit vulnerabilities with unprecedented speed and precision. Digital wallets, particularly non-custodial ones, are becoming prime targets due to their decentralized nature and associated security complexities. This scenario requires cryptocurrency users to adopt robust security practices, including multi-factor authentication, cold storage, and constant monitoring of suspicious transactions.
