The BadIIS malware-as-a-service ecosystem, attributed to Chinese-speaking cybercrime operators by Cisco Talos, is actively compromising Microsoft IIS servers at scale via native-code IIS module injection for traffic hijacking, SEO fraud, and persistent access sold to multiple criminal operators. This campaign item also encompasses CISA’s inadvertent exposure of credentials to a public GitHub repository and the NYC Health + Hospitals biometric data breach. No CVEs are assigned to the IIS campaign; vendor advisories for co-disclosed vulnerabilities in TP-Link, Adobe Photoshop, OpenVPN, and Gen Digital Norton VPN were not provided with CVE IDs in source data.
