    IAM for Autonomous Systems: Here's What You Need to Know

    This story was originally published on HackerNoon at: https://hackernoon.com/iam-for-autonomous-systems-heres-what-you-need-to-know. Autonomous systems cannot scale on issued credentials. IAM for Autonomous Systems replaces issued tokens with derived, per-action, offline-verifiable authority. Check more stories related to cybersecurity at: https://hackernoon.com/c/cybersecurity. You can also check exclusive content about #iam, #cybersecurity, #authorization, #sdk-development, #mcp-server, #cryptography, #autonomous-ai-agents, #machine-identity, and more. This story was written by: @blackboxengineering. Learn more about this writer by checking @blackboxengineering's about page, and for more stories, please visit hackernoon.com. Traditional IAM issues credentials, a model built for humans that breaks at machine speed: broad tokens, big blast radii, and an issuer bottleneck on every action. This article introduces IAM for Autonomous Systems, where authority is derived, not issued. In AgentEnvelope, the action envelope (operation, resources, time window, limits) is the credential: each capability is derived cryptographically from a customer-held root and the canonical action description, verifiable offline with no issuance service in the loop. A second layer, legitimacy, lets governance deny actions that are still validly signed but contradicted by current evidence. The SDK and MCP server are open source (Apache 2.0), and the protocol is published as an IETF Internet Draft.

    SonicWall's Remediation Guidance Says the Patch Is Only Step One of Four

    This story was originally published on HackerNoon at: https://hackernoon.com/sonicwalls-remediation-guidance-says-the-patch-is-only-step-one-of-four. SonicWall confirmed two SMA 1000 zero-days under active exploitation. Its own remediation guidance ends with resetting TOTP tokens. Here's why that matters.

This story was written by: @nickmarsteller. Learn more about this writer by checking @nickmarsteller's about page, and for more stories, please visit hackernoon.com. SonicWall disclosed two SMA 1000 flaws on September 1, both exploited in the wild: CVE-2026-83548, a pre-auth SSRF scoring CVSS 10.0, and CVE-2026-83549, an OS command injection. Chained, they reach unauthenticated RCE. The overlooked part is SonicWall's own guidance for a confirmed compromise — re-image, change all passwords, and reset TOTP tokens. A VPN gateway is an authentication store. A patch closes the code path; it cannot un-copy the seeds an intruder already took.

    Inside Immutable Backup Architecture: How Air-Gapped and WORM Storage Actually Stop Ransomware

    This story was originally published on HackerNoon at: https://hackernoon.com/inside-immutable-backup-architecture-how-air-gapped-and-worm-storage-actually-stop-ransomware.

Ransomware doesn't have to break your backups if it can steal the credentials that control them. Immutability moves deletion and modification rules below the backup application. Air-gapping removes the attacker's network path. Neither is sufficient alone. The real question is where your recovery boundary sits, the point where a compromised production identity stops being able to control the recovery copy.

    What the NetNut Takedown Reveals About Residential Proxy Sourcing

    This story was originally published on HackerNoon at: https://hackernoon.com/what-the-netnut-takedown-reveals-about-residential-proxy-sourcing. NetNut's takedown exposed a structural sourcing problem in residential proxies, and why owned infrastructure is what actually matters. Check more stories related to cybersecurity at: https://hackernoon.com/c/cybersecurity. You can also check exclusive content about #cybersecurity, #web-scraping, #data-privacy, #botnets, #proxy-servers, #netnu, #proxy-sourcing, #netnu-takedown, and more. This story was written by: @marae. Learn more about this writer by checking @marae's about page, and for more stories, please visit hackernoon.com. NetNut's residential proxy network was disrupted by the FBI and Google in July 2026, after reporting found a large share of its IP pool was sourced from compromised devices. The deeper issue is structural, most residential proxy brands resell capacity from upstream networks they don't directly control, which makes sourcing nearly impossible for buyers to verify. A small number of providers, including Bright Data and Squid Proxies, own their infrastructure outright instead of reselling, which is the actual difference worth checking before trusting any "ethically sourced" claim.
