CoinMarketCap Hacked Via Doodle Image Malware

CoinMarketCap, a prominent platform for tracking cryptocurrency market data, recently fell victim to a security exploit that briefly compromised its front-end system. The incident involved hackers injecting malicious code through a seemingly innocuous doodle image displayed on the homepage. This code triggered fake wallet verification pop-ups, instructing users to "Verify Wallet," a tactic designed to phish for access to their cryptocurrency holdings.

The breach was confirmed by CoinMarketCap and was traced to its backend API, which delivered a manipulated JSON payload embedding JavaScript into the homepage. According to blockchain security firm Coinspect Security, the attack exploited the platform’s rotating “doodles” feature, allowing attackers to embed the malicious code without altering the site’s core infrastructure.

The unauthorized pop-up was live for a short period before being removed by CoinMarketCap’s security team. The company acted swiftly upon discovering the issue, implementing measures to isolate and mitigate the problem. However, CoinMarketCap has not disclosed the number of users affected by the exploit or whether any wallets were compromised as a result.

This incident highlights the ongoing challenges faced by cryptocurrency platforms in securing their systems against sophisticated cyber threats. The use of seemingly harmless features, such as doodle images, to inject malicious code underscores the need for vigilant security measures and continuous monitoring to protect user data and assets.
