China-Linked Red Menshen Uses Stealthy BPFDoor Implants to Spy via Telecom Networks

A long-term and ongoing campaign attributed to a China-nexus threat actor has embedded itself in telecom networks to conduct espionage against government networks. The strategic positioning activity, which involves implanting and maintaining stealthy access mechanisms within critical environments, has been attributed to Red Menshen, a threat cluster that's also tracked as Earth Bluecrow,

The Age-Gated Internet: Child Safety, Identity Infrastructure, and the Not So Quiet Re-Architecting of the Web

In enterprise environments, identity effectively became the control plane once network perimeters broke down (e.g. zero trust, et cetera).

I’m seeing a similar pattern emerging on the public internet via age verification and safety regulation, but with identity moving closer to the access layer itself.

Not just: β€œAre you over 18?”

But: identity assertions are becoming part of how access is granted at the OS/device/app store level.

From a security perspective, this seems to introduce some new attack surfaces:

  • high-value identity tokens at the OS/device level
  • new trust boundaries between apps, OS, and third-party verifiers
  • incentives to target device compromise or token reuse rather than account-level bypass
  • potential centralisation of identity providers as enforcement points

Questions I’m trying to think through:

  • Does this effectively make identity providers the new perimeter/control plane?
  • How would you model this system (closer to DRM, identity federation, or something else?)
  • What are the likely failure modes if this layer becomes centralised?
  • Are decentralised / on-device credentials actually viable from a security standpoint, or do they just shift the attack surface?

Curious how people here would threat model this or where the obvious breakpoints are.
