Today, the world’s largest crypto data platform, CoinMarketCap, announced a security breach that appears to be unresolved.
Details of the Breach
On June 20, 2025, CoinMarketCap’s security team flagged a vulnerability related to a doodle image on their homepage that secretly triggered malicious pop-ups asking users to ‘Verify Wallet’ through unsafe links.
Official Measures by CoinMarketCap
The team quickly removed the infected asset. In their official statement, CoinMarketCap indicated that the cause was identified and new protective measures were implemented. 'All systems are now fully operational, and CoinMarketCap is safe and secure,' the company stated.
User Warnings
Despite the reassurances from CoinMarketCap, users remain skeptical. Many report prompts for unsafe external links. A public update from CoinMarketCap advised users not to connect their wallets and to exercise caution while interacting with the site.
The CoinMarketCap breach serves as a reminder that even the largest platforms in the crypto industry are not immune to security threats.
