Binance founder CZ has issued a warning to cryptocurrency projects about security threats posed by North Korean hackers. He highlighted four common infiltration techniques: impersonating job seekers to gain access to development, security, or finance roles; posing as employers to send employees malicious "updates" or "sample code"; embedding malicious links in customer service tickets; and bribing employees and contractors for data access. CZ urged crypto platforms to enhance employee training and candidate screening, strictly prohibit unauthorized file downloads, and maintain vigilance.
