Full breach record for Gomomentum.com →Threat-actor claim — not a regulatory filing
This row is a claim by the ransomware group Endzone on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Revenue: $221.7 million Momentum is a telecommunications company founded in 2001 that provides cloud-based communication solutions for businesses, specializing in cloud voice services, managed networks, SD-WAN solutions, and Microsoft Teams Phone integration. We gained access to a diagnostic and provisioning tool used by Momentum through a compromised Multi-Service Operator (MSO). Upon reconnaissance, we identified multiple critical vulnerabilities throughout the system. This tool controls internet and voice services for millions of users across global markets. We successfully accessed user data for every MSO, exposing personally identifiable information (PII) for over 7.5 million users. They didn't notice the prolonged access or the customer data dump for a while, but when we started deleting modems they noticed. They kept burning access and we gained it back, they'd burn it again. We removed modem packages for 58,127 users across the United States. That's 58,127 people without internet service right now. Families, businesses, students all cut off from the digital world. This is the direct result of their negligence and failure to secure their systems. These services can be restored immediately with the click of a button on our tool but you must reach out. Momentum management should contact us to discuss resolution.

Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
