币界网报道：According to Cointelegraph, the security team of cryptocurrency exchange Kraken pointed out that participants of industry conferences generally lack basic security awareness. Nick Percoco, security director, said in a blog on June 5 that a large number of participants were found to leave unlocked laptops and mobile phones at random, and wallet notifications popped up in real time, making them easy targets for criminals. Percoco warned that scammers often attack through "charging hijacking" (malicious USB ports) and fake WiFi networks. He suggested that participants use temporary wallets with only a small amount of funds and avoid discussing transaction details in public. The security team also found that some participants openly talked about high-value transactions in non-conference venues such as hotels, while wearing conference certificates containing personal information. Kraken emphasized that cryptocurrency users should always keep their devices locked and be wary of potential risks such as QR code replacement. Percoco reminded that industry activities gather a large number of technicians, including those with hacking capabilities, and an unencrypted connection may cause asset losses.
