According to Cointelegraph, the security team of cryptocurrency exchange Kraken pointed out that industry conference participants generally lack basic security awareness. Security director Nick Percoco stated in a blog post on June 5th that a large number of attendees were found to have left unlocked laptops and phones at will, with wallet notifications popping up in real-time, making them easy targets for criminals. Percoco warns that scammers often carry out attacks through "charging hijacking" (malicious USB interfaces) and forging WiFi networks. He suggested that attendees use temporary wallets with only a small amount of funds left and avoid discussing transaction details in public. The security team also found that some participants openly discussed high-value transactions in non conference venues such as hotels, while wearing conference credentials containing personal information. Kraken emphasized that cryptocurrency users should always keep their devices locked and be alert to potential risks such as QR code replacement. Percoco reminds that industry activities gather a large number of technical personnel, including those with hacking capabilities, and an unencrypted connection may result in asset loss.
