Phantom Wallet Lawsuit Highlights Security Concerns After $500,000 Theft

A group of investors has taken legal action against Phantom Technologies and OKX, alleging that significant security shortcomings in Phantom's wallet led to a $500,000 theft. This incident not only caused substantial financial losses but also contributed to the collapse of the Wiener Doge Solana token. The lawsuit, filed in the Southern District of New York, raises questions about the safety of digital asset storage and the responsibilities of crypto platforms.

The complaint, led by attorney Liam Murphy, centers on a January 20 cyberattack that exploited vulnerabilities in Phantom’s browser extension. Hackers accessed Murphy’s crypto holdings, liquidating assets worth over $500,000 and triggering a 99% drop in Wiener Doge’s value. The Solana based memecoin, once valued at over $3 million, fell from $3.1 per token to less than $0.01. Investors argue that Phantom’s failure to secure private keys properly enabled the devastating breach.

Allegations of Negligence and Misrepresentation

According to the lawsuit, Phantom stored users’ decrypted private keys in browser memory, a design flaw that allowed hackers to bypass standard security measures. The filing claims Phantom was aware of this vulnerability yet continued to market its wallet as a secure option for crypto storage. This oversight allegedly left users, particularly those less experienced with cybersecurity, exposed to malware, phishing attacks, and rogue extensions. The integration with OKX’s services is said to have facilitated the rapid conversion of stolen tokens into Solana, amplifying the damage.

The plaintiffs, including thirteen of Murphy’s friends and family, accuse Phantom of operating without proper registration and neglecting basic cybersecurity protections. They also allege that OKX’s role in enabling the liquidation of assets was critical to the hacker’s success. The group is seeking damages based on Wiener Doge’s peak value of $3.1 per token, reflecting their significant losses. The case highlights some of the risks of using digital wallets in the crypto space.
