Cointelegraph and CoinMarketCap Hacked: Why Non-Custodial Wallets Are Necessary

Summary

On June 20, 2025, CoinMarketCap experienced a hack involving malicious JavaScript that prompted users to connect their wallets, resulting in the theft of over $18,000 from 39 victims. The site quickly removed the script and patched the vulnerability. A similar attack occurred on Cointelegraph on June 23, where an ad network was compromised to display a fake token airdrop, leading to further losses. Both incidents highlight a rise in wallet-targeting hacks, which, while less frequent, can yield significant financial losses. Users are advised to be cautious with unexpected pop-ups and to verify information from trusted sources. Best Wallet, a new Web3 wallet, offers features to enhance security and protect against such phishing attacks. The Best Wallet Token ($BEST) presale has raised $13.5 million, with potential for significant returns. Security measures in the evolving crypto landscape are crucial for user protection.
