A managed endpoint no longer bounds insider exposure.
Apple Intelligence on Mac acts within existing user access with no confirmed runtime monitoring, creating an insider exposure the board must constrain now.

A heap overflow and SSO misconfiguration compromised OpenAI internal repos. Two controls named as present, neither enforced in effect.

Admin access to Baseten's production GitHub was reached in 25 minutes. A briefing on the identity boundary that failed and what the number means.

Google's anti-scraping update changed a control scrapers never owned, exposing the structural risk of building on an interface you cannot see or govern.

An unauthorized live feed of every ID verification let attackers bypass MFA for over a year. Why readable verification output stops being proof.
Nobody had to hack your meetings.
Over 180,000 tl;dv meetings were left open because access to recorded content was not conditioned on validated identity. What that failure exposes.
The record is the authority
A for-sale DNS record sells naming authority itself, and every control above DNS keeps validating the name for whoever now holds the record.
