A New SonicWall Scanning Spike Echoes the Pattern That Preceded CVE-2026-0400
Security researchers at GreyNoise have detected a new spike in scanning activity targeting SonicWall devices that follows a similar pattern to activity preceding a prior vulnerability (CVE-2026-0400). The researchers are documenting the activity and providing guidance on indicators defenders should monitor.
Why it matters: Network defenders relying on SonicWall appliances need to investigate scanning patterns immediately, as historical precedent suggests this activity may precede active exploitation of a vulnerability.
