In June 2025, CoinMarketCap and Cointelegraph, leading cryptocurrency platforms, suffered significant hacks exploiting user interface vulnerabilities. Attackers injected malicious JavaScript code, creating realistic-looking “Connect Wallet” pop-ups on the sites' homepages. These pop-ups tricked users into granting full access to their wallets, resulting in significant financial losses. The CoinMarketCap hack affected 39 victims, with losses exceeding $18,000. The Cointelegraph hack involved a compromised ad network, displaying a fake token airdrop popup for a nonexistent “CTG” token, leading users to phishing sites. These incidents highlight a concerning trend: attacks targeting wallet connectivity features, which, according to CertiK, caused over $1.45 million in losses during Q1 2025 alone. While these attacks represent a smaller percentage of total incidents, their success rate in siphoning funds is alarmingly high. Experts, including Binance's CZ, warn users to exercise extreme caution when authorizing wallet connections. The attacks emphasize the importance of vigilance and recognizing warning signs like unexpected pop-ups, even from trusted sources. The article promotes Best Wallet, a non-custodial Web3 wallet offering a presale directory for audited tokens and employing Multi-Party Computation technology to protect user keys from phishing. Best Wallet's token ($BEST) aims to further enhance the ecosystem's security and offer additional perks to holders. The hacks underscore the evolving nature of cryptocurrency security threats, transitioning from backend attacks to user interface exploits. Non-custodial wallets, like Best Wallet, are presented as a crucial solution to mitigate these emerging risks. The article concludes by urging readers to conduct thorough research before investing in any crypto service.
