Anthropic's own test: Red Team access blocked nothing, as it expected, and Defense let 4 of 50 trials succeed

Anthropic's 6 October CVP page: Red Team 34 of 50 against 67.6% unfiltered, Defense 4 of 50 through. What the run does not show, the 134,500 against 135,610 vulnerability counts, UK GDPR and Computer Misuse Act points, and a checklist.

A dark office desk at night with an open graphite laptop on the right whose screen shows a mailbox list of eight blank rounded rows, the fourth carrying an amber paperclip outline and a small padlock outline, with a coiled network cable and an unmarked USB security key on the desk in front.

Passkeys urged after a 417% rise in reported losses that Report Fraud's own assessment links to its new service

Reports rose 34 per cent but victims reporting a loss rose 10.3 times, and no document says how the accounts were taken. A passkey closes one door; recovery and fallback sign-in are others.

A smartphone lying on a dark desk showing a shopping app of blank product tiles, with one wide notification banner of empty rounded shapes dropped across the top, outlined in thin amber. Nothing carries any lettering.

ASOS confirms the 10am notification was unauthorised, cites third-party platforms and does not name Snowflake

The LibreOffice fix shipped on 24 July and the advisory on 5 October. OpenOffice still has no released fix and a public proof of concept has existed since 5 October. What each project documents, and what to do first.

A dark hospital corridor at night with, on the right, a wheeled patient monitor with a blank screen, a drip stand carrying a fluid bag and an infusion pump, and in front of them an open laptop on a trolley whose screen shows a device list of eight blank rounded rows, one outlined in amber, to suggest a device inventory with nothing filled in.

Forescout's 6% for medical devices is an OpenSSH version test, not proof they cannot be upgraded

What Forescout's report states about 6% of medical devices and 31% TLS 1.3 on exposed systems, what it leaves out, what the NCSC, NHS England and the MHRA say, and a UK checklist in the order worth doing.

AI Security6 Oct 2026

Adversa's Copilot CLI attack ran in 50% of runs on one of three models, and the post gives no run count
