nvd0rz is a criminal VoIP-focused intrusion set associated with the broader ecosystem of actors competing for control of vulnerable internet-exposed FreePBX, Elastix, Issabel, and Sangoma systems for toll-fraud operations. The actor is identified primarily through artifacts and account names targeted for removal by a rival FreePBX malware operation, indicating nvd0rz maintained implants, persistence, or access on compromised PBX infrastructure. Activity attributed to this ecosystem centers on International Revenue Share Fraud, in which compromised SIP trunks and Asterisk call-origination capabilities are abused to place premium-rate calls through attacker-controlled telephony infrastructure. Available evidence supports nvd0rz as one of several competing criminal operators in this space, alongside names such as Juba VoIP, Nahda, Badr or b3d0r, tchTowr, and yokyok. High-confidence details about nvd0rz’s independent tooling, infrastructure, victimology, or geographic origin are currently not available.
