User: Tell me about the LinkedIn data breach

Claude: # LinkedIn Data Breach

**Date:** 2012-05-05
**Domain:** linkedin.com
**Accounts affected:** 164,611,595
**Verified:** Yes
**Data leaked:** Email addresses, Passwords

**Description:**
In May 2016, LinkedIn had 164 million email addresses and passwords exposed. Originally hacked in 2012, the data remained out of sight until being offered for sale on a dark market site 4 years later. The passwords in the breach were stored as SHA1 hashes without salt, the vast majority of which were quickly cracked in the days following the release of the data.

**Recommendations:**
- If you had an account on this service, change your password
- If you used the same password elsewhere, change those too
- Monitor your accounts for suspicious activity
- Be cautious of phishing attempts that may use this leaked information

Listar todas las infracciones

User: List all Adobe data breaches

Claude: Found 1 breaches for domain adobe.com:

1. Adobe (2013-10-04)
   Domain: adobe.com
   Accounts affected: 152,445,165
   Compromised data: Email addresses, Password hints, Passwords, Usernames

Notas de seguridad

La función de verificación de contraseñas utiliza k-anonimato para verificar contraseñas sin enviar la contraseña completa a la API Have I Been Pwned
Solo se envían a la API los primeros 5 caracteres del hash SHA-1 de la contraseña
La API devuelve una lista de sufijos hash que coinciden con el prefijo y la verificación se completa localmente.

Configuración de la clave API

Este servidor requiere una clave API de Have I Been Pwned para la mayoría de las funciones (excepto la verificación de contraseñas). Puedes obtener una clave API en haveibeenpwned.com/API/Key .

La clave API debe proporcionarse como una variable de entorno denominada HIBP_API_KEY en la configuración de MCP.
