THE BLOCK: Open-source Bitcoin hardware maker Foundation said it has identified spam emails that came from its official domains. The company traced the issue to one or more compromised Cloudflare API keys, which it has since revoked. It also took down the malicious domain used in the emails. Foundation stated that funds stored on Passport devices remain safe and that the hardware itself was not compromised. This comes amid an unprecedented, AI-fueled global cybersecurity crisis.
