Lo que pasa por las cloacas cuando no estás mirando

Si una imagen vale más que mil palabras (en realidad no existe un paper que lo confirme) ¿Cuanto valdrá una palabra en una imagen? ¿1000 + 1?.

En el grupo Antifraude de Hispasec "la cañería de SPAM" recibe una magnitud ridículamente sorprendente. Imagina un número y casi siempre te quedarás corto. Naturalmente, examinar ese montón inhumano de excrecencias binarias producidas por bots solo es digno de ser tratado por...otro bot. Así que, en circunstancias normales, "el alcantarillado" no suele ser abierto por un ser andromorfo, es el sistema el que, en base a reglas, te devuelve algo que cree interesante. Una de las reglas es algo especial, detecta SPAM defectuoso, lo que a veces permite (seguro que has visto esto antes) dedicar un momento jocoso a pesar del contexto.


Por cierto que el departamento de Análisis de Malware (aparte de las risas) le echó la zarpa al ejemplar y con un par de vistazos al microscopio diagnosticó un TeslaCrypt de primero de carrera adjunto al protoSPAM.

Eso es todo amigos, hasta $despedida.rand(0,3){"pronto"|"luego"|"mañana"|"la vista"};

This concept could be explored further in literature dissertation topics on cybersecurity strategies and technologies.
