Cyberside Chats: Cybersecurity Insights from the Experts

Amazon released two security disclosures in the same week — and together, they reveal how modern attackers are getting inside organizations without breaking in.

One case involved a North Korean IT worker who entered Amazon’s environment through a third-party contractor and was detected through subtle behavioral anomalies rather than malware. The other detailed a years-long Russian state-sponsored campaign that shifted away from exploits and instead abused misconfigured edge devices and trusted infrastructure to steal and replay credentials.

Together, these incidents show how nation-state attackers are increasingly blending into human and technical systems that organizations already trust — forcing defenders to rethink how initial access really happens going into 2026.

 

Key Takeaways

1. Treat hiring and contractors as part of your attack surface.

Nation-state actors are deliberately targeting IT and technical roles. Contractor onboarding, identity verification, and access scoping should be handled with the same rigor as privileged account provisioning.

2. Secure and monitor network edge devices as identity infrastructure

Misconfigured edge devices have become a primary initial access vector. Inventory them, assign ownership, restrict management access, and monitor them like authentication systems — not just networking gear.

3. Enforce strong MFA everywhere credentials matter

If credentials can be used without MFA, assume they will be abused. Require MFA on VPNs, edge device management interfaces, cloud consoles, SaaS admin portals, and internal administrative access.

4. Harden endpoints and validate how access actually occurs

Endpoint security still matters. Harden devices and look for signs of remote control, unusual latency, or access paths that don’t match how work is normally done.

5. Shift detection from “malicious” to “out of place”

The most effective attacks often look legitimate. Focus detection on behavioral mismatches — access that technically succeeds but doesn’t align with role, geography, timing, or expected workflow.
