operational guidance (Anthropic customer notice via Byline Network, Nov 7)
Tip: after Anthropic's customer notice, ignore out-of-band "security" or billing asks that want passwords, OTPs or payment details
- Do not click password-reset or "verify billing" links from unexpected Anthropic-branded email.
- Enterprise admins: remind finance and IT that plan tier and spend figures may now be known to a third party and are useful social-engineering bait.
