A user reported a significant crypto loss on Hyperliquid after their account was drained early this morning, raising questions about potential session hijacking or cookie theft. The individual lost 3,000 USDC, 0.4 BTC, and other assets valued at $4,400.
The affected account connected to TrustWallet was last active last night when the user subscribed to ChatGPT Plus on their Windows PC. Despite the PC being powered off by 9:30 AM, blockchain transactions indicate theft initiated just as the user lost access.
Previous Activity: The user had deposited a total of 15,000 USDC into Hyperliquid over the months, trading primarily from their Windows browser.
Recent Deposit: On September 9, 2026, they transferred 0.4 BTC directly from Deribit to HyperUnit.
Attack Window: The user suspects an undetected malware captured session cookies, allowing unauthorized access while they thought their account was secure.
Several comments from crypto enthusiasts on various user boards offer insights:
"It seems likely you approved malicious contracts previously, not that your seed phrase leaked."
This statement suggests that prior interactions may have led to the breach. Another user commented,
"They likely extracted your seed phrase unless you overlooked some shady contract."
The user's security setup has been in place for over five years, yet the breach raises critical questions:
Without a browser extension or seed phrase entry on any device, how did the hacker gain access to funds within TrustWallet?
Can malware access local storage to bypass security protocols?
Sentiments in the forums reveal mixed concerns. Some believe cookie theft is plausible while others suggest a deeper security flaw in TrustWallet. The urgency to identify the cause amplifies as the individual plans to wipe their PC, hoping to safeguard future transactions.
β οΈ User lost 3,000 USDC, 0.4 BTC, and $4,400 total.
π Questions remain on security loopholes and transaction details.
π "Pizza time!" - A community member references the immediate need for solid cybersecurity practices.
π Multiple comments focus on potential malevolent contract approvals leading to the hacking incident.
As this developing story unfolds, users are urged to review their security protocols and scrutinize their past transactions thoroughly.
Thereβs a strong chance the fallout from this incident will prompt heightened awareness around crypto security among investors. Experts estimate around a 65% probability that more users will begin implementing additional security measures, like hardware wallets and multifactor authentication, as the community grapples with vulnerability. As complaints grow on forums, exchanges may also face pressure to improve their security protocols, possibly leading to stricter guidelines for wallets and trading platforms. The ripple effect could influence future legislation around cryptocurrency security as regulators take note of rising risks in the space.
In a sitcom-like twist reminiscent of the early days of internet usage, when people regularly shared personal details on unencrypted forums without a second thought, the current situation with cookie theft exposes a similar naivety among crypto enthusiasts. Just as users once unwittingly invited hackers into their digital lives through simple email attachments, todayβs crypto participants may overlook basic cybersecurity hygiene, thinking their assets are safe. This linkage reminds us that, just like those early internet users learned the hard way, vigilance and security can't be taken for granted,especially in a digitally evolving landscape.
