An unidentified attacker compromised at least 143 devices across 34 countries and installed the legitimate bandwidth-sharing application Pawns.app without owners’ consent, monetizing victims’ internet connections. GreyNoise reported exploitation of vulnerabilities in D-Link ShareCenter NAS devices, Ubiquiti UniFi Video NVR systems, and SAP NetWeaver Visual Composer; Hikvision and Dahua recording devices were also targeted. In some cases, the attacker added SSH keys to maintain backup access.
The campaign exposes device owners to unwanted proxy traffic, IP address blocking, and potential allegations of illegal activity conducted through their connections. GreyNoise’s investigation also highlighted a separate intrusion at an unnamed organization, confirmed after investigators noticed multiple users authenticating through the same residential proxy IP address. Defenders should scrutinize shared residential proxy addresses in authentication logs, investigate behavioral anomalies rather than relying on geolocation alone, and check affected systems for unauthorized bandwidth-sharing software and SSH keys.

5 events from the most recent confirmed update back to the earliest known activity.
GreyNoise identified 209.99.190.80 as an exploitation IP address and skynox7@proton.me as the attacker's Pawns payout account, and published seven SHA-256 hashes for associated Pawns.app binaries. It cautioned that the binaries were not necessarily malware; their unauthorized installation constituted the malicious activity.
The attacker configured some compromised devices to accept attacker-controlled SSH keys, providing a backup access mechanism.
An unidentified attacker exploited D-Link ShareCenter NAS vulnerabilities CVE-2024-3272 and CVE-2024-3273, CVE-2021-44228 in Ubiquiti UniFi Video NVR, and CVE-2025-31324 in SAP NetWeaver Visual Composer, installing Pawns.app without authorization to monetize victims' bandwidth. The campaign compromised at least 143 devices across 34 countries and also targeted Hikvision and Dahua recorders, although successful compromises of those products were not confirmed.
The organization discovered multiple users authenticating through the same residential proxy IP address and subsequently confirmed a serious intrusion. GreyNoise withheld further details of the investigation.
During a product demonstration, GreyNoise identified malicious-labeled IP addresses in an unnamed organization's Entra ID sign-in logs. The addresses were residential proxies in locations consistent with the organization and its users.
