Attacker hijacks D-Link, Ubiquiti and other devices to sell bandwidth via Pawns.app

GreyNoise says it found at least 143 compromised devices across 34 countries silently enrolled in the Pawns.app residential proxy network without owner consent. The attacker exploited known flaws including CVE-2024-3272/3273 in D-Link ShareCenter NAS, CVE-2021-44228 in Ubiquiti UniFi Video NVR, and CVE-2025-31324 in SAP NetWeaver Visual Composer, and also targeted Hikvision and Dahua DVR/NVR devices. In some cases SSH keys were added for persistent backup access.

Citrix and Kiteworks take opposing approaches to zero-day disclosure over same weekend

Citrix patched eight NetScaler vulnerabilities, including two actively exploited zero-days, after researchers reported RCE attacks scanning for vulnerable installations and urged customers to take systems offline immediately. Citrix instead advised customers to upgrade promptly rather than disconnect servers, and the two zero-days continued to be exploited despite the patch. Separately, Kiteworks told customers to proactively take systems offline based on intelligence of an imminent attack before confirming the next day that only about 1% of customers were actually affected.
