SonicWall confirmed two SMA 1000 zero-days under active exploitation. Its own remediation guidance ends with resetting TOTP tokens. Here's why that matters.

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.

Ransomware doesn't need to crack your backups if it can steal the credentials that control them. Here's how immutability and air-gapping actually build a recove

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.

Vendor software can introduce models, runtimes, retrieval pipelines, and agent tools into an organization’s infrastructure. Security teams should inventory these components, verify provenance, restrict access, and monitor behavior rather than assume existing vendor reviews cover them.

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.
