Early today, May 13, 2025, hackers gained access to the X accounts of ZKsync and Matter Labs through third-party accounts that had permission to post on their behalf.
These accounts, called delegated accounts, were not properly secured, allowing the attackers to take over.
If you’re wondering, ZKsync is a popular technology that helps make Ethereum transactions faster and cheaper, faced a serious security issue.
The security breach led to a depreciation in the ZK token’s market value and highlighted persistent vulnerabilities in blockchain ecosystems.
The hackers used the compromised accounts to spread false claims that ZKsync was under investigation by U.S. authorities, causing panic among investors, and to share links to a fake “airdrop” in an attempt to trick users into revealing their wallet credentials.
The crypto community quickly flagged the suspicious activity and warned others to steer clear of the links, highlighting just how vulnerable social media accounts can be without proper security measures.
The fake posts had an immediate impact. ZKsync’s ZK token dropped between 6.4% and 8% in a single day, falling from about $0.071 to $0.07.
This wiped out some of the token’s recent gains, which had stemmed from technology upgrades aimed at making ZKsync more efficient.
Beyond the price drop, the incident shook confidence in the platform. Investors and users voiced concerns about ZKsync’s security, especially since this wasn’t its first issue.
In April 2025, a hacker stole millions of ZK tokens but later returned most of them. The recurrence of such breaches raised broader questions about how well crypto projects safeguard their systems.
Response and Recovery
Social media is a powerful tool for crypto projects to share updates, but it can also spread misinformation and steal data. The false claims about ZKsync caused panic and devalued its token, illustrating how quickly misinformation can spread.
For crypto projects, this highlights the need for strong security measures, such as restricting who can post on accounts and implementing extra protections for sensitive systems.
The hack is part of a broader trend. Early this year, other platforms like Curve Finance were targeted, resulting in billions in losses. As crypto grows, so do the threats, making security a top priority.
The ZKsync breach was a wake-up call for the crypto community. Although ZKsync quickly regained control, the incident demonstrated how easily hackers can exploit vulnerabilities to create chaos.
