Summary
- An incident was reported in which about $5,000 worth of crypto was stolen while using public Wi‑Fi.
- The hacker reportedly exploited a wallet request signature during trades on Jupiter (JUP), a Solana (SOL)-based decentralized exchange (DEX), over the hotel’s password-free public Wi‑Fi environment.
- Some noted the claim that the attack was carried out solely via public Wi‑Fi is unlikely, and raised the possibility of an unencrypted communications environment or an additional malware infection.

A crypto (virtual asset) investor was reportedly robbed of funds after using public Wi‑Fi.
According to crypto outlet U.Today on the 10th (Korea time), a trader using the pseudonym “The Smart Ape” claimed that after using a hotel Wi‑Fi network, about $5,000 worth of crypto was stolen.
Specifically, he said he executed trades on Jupiter (JUP), a Solana (SOL)-based decentralized exchange (DEX), using the hotel’s password-free public Wi‑Fi. During the process, he signed a required wallet request signature, and the incident reportedly occurred afterward.
The Smart Ape claimed, “I signed to approve access permissions, not to transfer funds, and a few days later all the funds in my wallet were drained.”
However, some have pointed out that the claim the attack was carried out solely via public Wi‑Fi is not very plausible. For such a hack to work, they say, it would require an unencrypted communications environment or an additional malware infection.
