Bankr Halts Swaps After $440K AI Exploit as CZ Urges API Key Rotation

Crypto security threats intensified on May 20 when Bankr suspended swaps and transfers following a $440,000 drain from at least 14 wallets via prompt-injection attacks on its AI trading assistant. The incident follows Binance founder CZ’s urgent call for developers to rotate API keys after a GitHub breach stole roughly 3,800 repositories through a malicious browser extension. The wave began May 17 with Jameson Lopp warning of sophisticated Google Forms phishing and continued May 19 when the Steam game “Beyond the Dark” was found embedding crypto-stealing malware. BTC traded near $78,000 as users adopted zero-trust practices amid rising concerns over hardcoded credentials and AI tooling.
