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.

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.

This article details a practical, in-house defense architecture: a forecast-driven, multi-dimensional rate limiter running on familiar libraries like Redis and Prophet. By dynamically modelling normal traffic ceilings and attributing excess to specific behavioral keys, you can safely intercept volumetric scraper and flood attacks at the edge before they impact your origin.

Enterprise Networks Know Who Connected. AI Agents Make the “Why” Harder
This story was originally published on HackerNoon at: https://hackernoon.com/enterprise-networks-know-who-connected-ai-agents-make-the-why-harder.
