A significant security breach at Ethereum Layer 2 network ZKSync has sent shockwaves through the cryptocurrency community. On April 15th, reports emerged of unauthorized access to their system, leading to a swift and dramatic escalation. The official team confirmed the incident on X around 10 AM, revealing that an attacker gained control over an administrative account holding approximately $5 million in ZK tokens – unclaimed tokens from previous airdrops. The attacker acted swiftly, converting this stolen cryptocurrency into ETH and transferring them through multiple transactions to a HitBTC-related address, triggering a cash-out process. 10 minutes later, the hacker’s attack escalated further. It has been revealed that three administrative accounts used for airdrop distribution contracts were compromised, allowing the hacker to mint a staggering 111 million unclaimed ZK tokens through a contract function. Following this unprecedented breach, several exchanges promptly suspended ZK token deposits and withdrawals, warning investors about potential price volatility. The price of ZK briefly plummeted to $0.03972 around 9:30 AM on April 15th, before recovering somewhat to its current value of $0.04762. However, the incident has left the cryptocurrency market with lingering uncertainty and concern about the future.
