ZKsync Admin Wallet Breach: $5M in ZK Tokens Stolen

On April 15, 2025, a security breach in the admin wallet of the layer-2 blockchain ZKsync resulted in hackers stealing $5 million worth of ZK tokens, which were unclaimed tokens from an ongoing ZKsync airdrop. ZKsync confirmed the incident via Twitter and stated that necessary security measures have been put in place. Following the breach, the ZK token experienced a sharp 14% price drop over the past 24 hours, alongside a 96% increase in trading volume, reaching $71 million. The protocol described the attack as an isolated event, limited to the airdrop contract, aiming to reassure the community that other aspects of the ecosystem remain unaffected.
