Wu learned that Kraken's Chief Security Officer Nick Percoco has warned that frequent security breaches at cryptocurrency industry conferences could lead to wallet theft, data breaches, and even personal risks. He pointed out that common hazards include unlocked devices, use of public Wi Fi, forgery of QR codes, USB charging attacks, etc. Kraken called on attendees to be vigilant and avoid discussing sensitive transactions or displaying identity information in public, and suggested using independent hotspots, limited wallets, and built-in charging devices to prevent becoming targets of hackers. https://www.
