A high-end holiday ended in a brutal wallet drain because a trader discussed portfolio specifics within earshot of a predator. By broadcasting their crypto involvement in a public lobby, the victim effectively painted a target on their back for anyone nearby. Because the hotel's "captive portal" offers zero isolation between connected devices, the attacker sat in the middle of the victim's traffic, waiting for the perfect moment to poison a browser session.
The breach happened via a deceptive Jupiter Exchange interface modification injected directly into the user's browser. As the victim initiated a standard swap, the attacker's code swapped the transaction payload for a "permanent approval" request. Because the victim was already in "trading mode," they blindly signed a technical prompt that gave the attacker a blank check to move SOL and tokens at a later date.
The Delayed Execution Trap
The drain didn't happen in the hotel lobby; the attacker played the long game, waiting for the victim to check out before cleaning out the assets. This strategic delay ensured the victim was far from the scene and less likely to trace the leak back to the hotel network. It is a classic "set-and-forget" exploit that turns a hot wallet into a ticking time bomb the moment an unsuspecting user hits Approve.
The victim admits their own arrogance was the real vulnerability, choosing hotel Wi-Fi over a secure mobile hotspot while signaling their "crypto" status to the entire room. This $5,000 error proves that even the best dApps cannot save you from a compromised network layer. If you are not using a dedicated mobile hotspot and a hardware-signed wallet while traveling, you are essentially handing your keys to the person sitting at the next table.
