Detected8 October 2026 · 18:21 UTC
A freshly posted leak claims 7.5 million customer PII records from Momentum Telecom, including names and home addresses. Although the company is US-based, a dataset of this size is a high-value asset for fraud, SIM-swap and phishing campaigns. Defenders in telecom and downstream sectors should monitor for credential and identity abuse.

Filtración de 7,5 millones de registros de clientes de Momentum TelecomA 7.5M-record customer PII database attributed to Momentum Telecom was freshly posted for download. The data reportedly includes names, home addresses and city details, enabling large-scale phishing, SIM-swap and account-takeover campaigns against subscribers. Telecoms are critical infrastructure, so defenders should correlate the claims with internal breach indicators and notify affected customers.Leak● 93
Filtración de datos del Gobierno de Mendoza con más de 1M de registros PIIA threat actor posted a database allegedly containing over 1 million PII records belonging to the Government of Mendoza, Argentina, freshly advertised on a leak forum. If authentic, it exposes citizen and employee personal data of a provincial government body, enabling phishing, identity fraud and targeted intrusion against public administration. Argentine government entities should urgently validate the exposure and watch for credential abuse and follow-on attacks.

Filtración masiva de 110M de credenciales URL:usuario:contraseñaA freshly dated dump claims 110 million URL:login:password stealer-log records, marked private and UHQ. Credential re-use makes this useful for account takeover, credential stuffing and initial access across many organizations. Despite being generic, its scale and recency warrant surfacing for defensive monitoring.Leak● 40
Base de datos de clientes de AT&T (correo y ubicación) publicadaA collection labelled as an AT&T customer base with email addresses and location data was posted on a leak forum. If authentic and current it would represent a large exposure of a US telecom subscriber base, but it may be a repost of earlier AT&T breach data, so its age should be verified before alerting. Telecoms are critical infrastructure, so any fresh customer-data leak warrants monitoring.

Filtración masiva de 110 millones de credenciales de stealer logsA 110-million-record URL:login:password dump sourced from stealer logs was posted, likely aggregated infostealer output rather than a single breach. While it names no victim, its sheer volume hands attackers a large pool of valid credentials for credential-stuffing against corporate and government accounts worldwide. Defenders should enforce MFA and monitor for reuse of credentials originating from this dump.Leak● 22
Base de datos de 23,5 millones de ciudadanos de Taiwán (2022) recirculadaA 23.5M-row Taiwan citizens database originally leaked in October 2022 is being recirculated. It is old, so not a fresh incident, but the scale and government-linked PII keep it valuable for identity fraud and social engineering. Treat it as historical context, not an active alert.
