Binance founder Changpeng Zhao issued a warning following security breaches at Cointelegraph and CoinMarketCap in June 2025, initiating a rise in phishing scams targeting users’ wallets through front-end compromises.
Cointelegraph and CoinMarketCap’s recent security breaches highlight vulnerabilities in crypto platforms’ front-end systems, underscoring the need for heightened vigilance in the cryptocurrency community.
Details of the Compromises
Both Cointelegraph and CoinMarketCap experienced breaches on their platforms. Cointelegraph’s ad system was compromised with malicious pop-ups, while CoinMarketCap’s doodle image triggered phishing attacks through an API vulnerability. Changpeng Zhao warned users of phishing risks.
The attacks led to phishing attempts targeting browser wallets such as MetaMask and Phantom. CoinMarketCap confirmed the issue was resolved and stated all systems are operational.
Cointelegraph’s website has been flagged for phishing activity.
Users experienced heightened caution after the hacks, calling for better ad and script screening on crypto sites. Financial theft totaled at least $5,490, primarily affecting individual wallet holders, rather than large-scale asset movements.
Community and Expert Reactions
The incident resembles past phishing attacks, utilizing compromised frontend components. No institutional regulatory responses have been confirmed. Community developers praised quick responses but emphasized the ongoing risks.
CoinMarketCap mentioned,
“On June 20, 2025, our security team identified a vulnerability related to a doodle image displayed on our homepage. This doodle image contained a link that triggered malicious code through an API call, resulting in an unexpected pop-up for some users when visiting our homepage. All systems are now fully operational, and the platform is safe and secure to use.”
Potential outcomes include stricter ad monitoring and enhanced security measures by crypto platforms to prevent similar incidents. Historical patterns indicate evolving phishing tactics could continue to threaten user wallets if front-end vulnerabilities persist.
