      "value": "ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer."

      "value": "ALPACA es un ataque de confusi\u00f3n de contenido de protocolo de capa de aplicaci\u00f3n, que explota servidores TLS que implementan diferentes protocolos pero que usan certificados compatibles, como certificados multidominio o comod\u00edn. Un atacante de tipo MiTM que tenga acceso al tr\u00e1fico de la v\u00edctima en la capa TCP/IP puede redirigir el tr\u00e1fico de un subdominio a otro, resultando en a una sesi\u00f3n TLS v\u00e1lida. Esto rompe la autenticaci\u00f3n de TLS y pueden ser posibles los ataques entre protocolos donde el comportamiento de un servicio de protocolo puede comprometer al otro en la capa de aplicaci\u00f3n"
