NVIDIA Blackwell accelerator concept with a compliance banner and a crossed-out China map silhouette

NVIDIA’s China Stance: No Active Talks on Blackwell, What It Is

NVIDIA’s Jensen Huang says there are no active discussions to sell Blackwell chips to China. Because U.S. export controls bind shipments and Beijing restricts foreign accelerators in state-funded data centers, near-term access looks unlikely. This analysis explains what that means for procurement, security, and model roadmaps and how to design for heterogeneous accelerators without betting your budget on rumors.

BGP upstream map highlighting AS30823 (aurologic) feeding multiple high-risk hosting ASNs across Europe

Sanctions vs. Transit: Aeza’s Reliance on aurologic Connectivity

aurologic GmbH (AS30823) operates a multi-terabit backbone out of Langen and connects multiple high-risk hosting providers including sanction-linked entities—giving malware C2 and staging servers durable reach. This analysis explains why upstream neutrality often translates into enablement, how TAEs cluster under aurologic, and what blue teams can do: upstream-aware detections, deny-by-default on risky cones, flowspec/RTBH during incidents, and procurement levers that force faster de-peering.

Legacy CVEs and misconfigured IIS enable stealth access via msbuild and DCSync

China-Aligned Abuse msbuild, DCSync After Legacy CVE Break-ins

A China-linked crew still breaks in through legacy CVEs Log4j, Struts, Confluence, GoAhead then hides behind scheduled tasks and msbuild.exe to run memory-resident payloads. They probe domain controllers with DCSync, and they target misconfigured IIS by abusing ASP.NET machine keys to deploy TOLLBOOTH with SEO cloaking. Reduce risk by patching edge services, restricting LOLBAS on servers, rotating machine keys, and alerting on replication from non-DC hosts.
