Mexico Telecom Fallout: NBX Soluciones Leak Exposes 497,597 Subscribers

HEROIC Cyber's DarkHive breach intelligence has confirmed that NBX Soluciones, a Mexican VoIP and telecommunications provider, suffered a database breach on December 27, 2024 that compromised 497,597 subscriber records. The leaked information includes phone numbers, first names, and last names, a contact-ready combination that is already circulating on underground forums.

Why This Telecom Database Breach Is Dangerous

A telecom subscriber list is one of the most valuable inputs for vishing and smishing campaigns. Attackers now hold half a million verified Mexican phone numbers tied to real names, letting them place spoofed calls or send targeted SMS that appear to come from a trusted carrier. Because no passwords leaked, victims often ignore the risk, yet the social engineering threat is immediate.

What Was Exposed in NBX Soluciones

• 497,597 subscriber records
• Phone numbers
• First names
• Last names

Why This Matters

NBX Soluciones powers Integra CRM and IP telephony for businesses across Mexico, so the exposed contacts include both consumers and staff at client companies. A criminal armed with a name and number can impersonate a carrier, spoof caller ID, or reference real account details to trick victims into handing over banking codes and one-time passwords.

How Telecommunication Database Breaches Work

Attackers frequently target smaller carriers and VoIP vendors because their customer databases link active phone numbers to verified identities. Once exfiltrated, the records are split into regional lists and sold to fraud rings that run call-center scams, SIM-swap schemes, and account recovery attacks using the leaked personal details as proof of identity.
