CZ says AI hacking fears in crypto are overblown, warns phishing is the real threat

Binance founder Changpeng “CZ” Zhao has a message for anyone losing sleep over AI cracking crypto’s encryption. That is probably not the problem you should be worried about. In a post on X on October 23, 2026, CZ argued that fears about AI hacking crypto are overblown. He added a caveat: AI can still cause real damage through leaked data, smarter phishing, and social engineering. What CZ actually said CZ’s core point was that AI does not need to defeat crypto’s encryption to have an impact. The cryptography protecting crypto systems is not the weak link in his view. AI makes phishing tactics better. Scam messages that once gave themselves away with clumsy grammar can now read like they came from a real colleague. When attackers pair that with personal details from old data leaks, a fake message can feel convincingly personal. CZ also noted that systems used by banks and the broader internet often rely on weaker encryption standards than those found in crypto, arguing that if AI-driven code-breaking ever becomes a serious threat, legacy systems with older protections would be the softer target. He signed off with a familiar catchphrase. “Stay SAFU!” A week of security warnings The A...
