Four KEV entries, one 61 day gap: Check Point's management server was attacked in July, fixed in September

Two of the four new KEV entries name Check Point, but only one is the management server. The take that fixes the other is the top of the vulnerable range for it. What the four advisories do not state matters more than what they do.

Qualcomm's two new flagships share one spec sheet, and the memory clock that binds on-device AI has not moved

Both Gen 6 parts state the same CPU clocks, the same 16 MB cache, the same 24 GB memory ceiling and the same 5300 MHz memory clock as the Gen 5 part they are measured against. The security block is identical on both, and shorter than Gen 5's.

AI Security23 Sept 2026

Anthropic ships Claude Opus 5.5 at 40% lower cost. Most cybersecurity tasks get routed to Opus 4.8 instead

Opus 5.5 leads seven of the nine benchmarks Anthropic published and loses two to GPT-6 Astra. The row that matters most for security teams is not in the table: cyber tasks fall back to an older model.

OpenAI halves GPT-6 Sol and Luna prices. Five of its six charts compare against numbers it did not measure

GPT-6 Sol is now $2 in and $10 out per million tokens, Luna $0.10 and $0.50. The charts behind the cut put OpenAI's own runs beside competitors' published reports, which OpenAI states in its own fine print.

Four of CISA's nine new ICS advisories are about borrowed code, and the lwIP fixes have no release

Nine ICS advisories, six of them republished Siemens notices, one flaw already on the known exploited list since May, and two fixes that no vendor can simply install. A prioritisation guide for UK OT owners.
