Hospitality Under Fire: PBX System Reconnaissance Reveals Critical Security Gaps
In September 2020, SANS Internet Storm Center detected targeted reconnaissance scans against hospitality industry applications, specifically focusing on the abandoned PIAF-HMS (PBX in a Flash Hospitality Management System) project. The scans originated from IP address 94.102.49.125, associated with bulletproof hosting provider IP Volume (AS202425), and targeted multiple hospitality-related endpoints including /admin/, /ucp/, /hms/, and /hotel/. The attackers used a distinctive user agent 'Farez-Sorter/1.0' and appeared to be exploiting recently disclosed SQL injection vulnerabilities in the decade-old, unpatched system that lacks proper input validation and authentication controls. This incident highlights the persistent targeting of hospitality infrastructure, where attackers seek to steal valuable guest personal data and potentially launch man-in-the-middle attacks. The focus on PBX systems suggests sophisticated attack vectors that could allow threat actors to impersonate internal hotel communications and manipulate guest interactions through compromised telephony infrastructure.
