- A front-end exploit was embedded on the CoinMarketCap homepage.
- A fake wallet prompt was triggered by malicious code.
- The site reported all systems have since been secured.
A fake wallet verification prompt briefly appeared on the homepage of CoinMarketCap, a cryptocurrency data aggregator, on Saturday.
The front-end exploit was traced to malicious code embedded in a homepage image, triggering a security investigation and warnings for users not to connect their wallets.
“Do not connect your wallet,” the company warned in its initial post on X.
The surprise homepage prompt quickly raised alarms, and wallet providers like MetaMask and Phantom reportedly flagged the site as suspicious.
CoinMarketCap later confirmed that the pop-up originated from a corrupted homepage doodle image that triggered a rogue API call.
The company said it removed the malicious code, identified the root cause, and deployed “comprehensive measures” to prevent further issues.
“We can confirm all systems are now fully operational,” it said in its latest update.
It’s not the first time the Binance-owned platform has faced security issues.
In 2021, more than three million email addresses linked to CoinMarketCap accounts appeared on hacking forums.
While the company said its servers weren’t breached, it acknowledged a correlation with its subscriber base.
The incident also taps into a growing fear among crypto users: their own mistakes.
A recent Kraken survey found that nearly half of respondents worry more about making a security error themselves than falling victim to hackers.
