Binance is facing hard questions after a single compromised engineer's laptop put $6 billion at risk, and the episode is bad news for anyone trusting crypto exchanges with their money.

• One engineer's hacked laptop allegedly exposed $6 billion at Binance, raising questions about whether it was ever that vulnerable.
• North Korea is suspected, since its hackers have a track record of breaking in through malware, phishing links, and fake job interviews — the same playbook used in last year's Bybit hack.
• Binance says its security team has blocked North Korea-linked attacks before, but has not yet explained how this laptop was compromised.
• The bigger worry is that a single point of failure could threaten billions in customer funds, and Binance has not yet released a full technical breakdown.

Outlook: Binance says it will publish a full investigation report, which should reveal whether this was a North Korean operation and whether exchanges need stronger internal safeguards.
