Ayer el\u00a0grupo hacker D33ds Company reclam\u00f3 la responsabilidad por atacar un servicio de Yahoo y exponer 453.492 credenciales de ingreso en texto sin cifrar<\/a>. Yahoo hoy confirm\u00f3400.000 de sus cuentas fueron hackeadas, aunque enfatiz\u00f3 que\u00a0menos del 5 por ciento<\/strong>\u00a0de las credenciales son v\u00e1lidas<\/a>. Puede verificar si su cuenta fue comprometida aqu\u00ed:\u00a0Sucuri<\/a>.<\/p>\n

Cuando uno tiene 450.000 contrase\u00f1as, se puede hacer un poco de an\u00e1lisis.\u00a0ESET<\/a>\u00a0uso el analizador de contrase\u00f1as\u00a0Pipal<\/a>\u00a0para compilar algunas estad\u00edsticas (el volcado completo de informaci\u00f3n est\u00e1 disponible en\u00a0Pastebin<\/a>).<\/p>\n

Para empezar, hab\u00edan aparentemente solo 442.773 contrase\u00f1as, contrariamente a la cifra mencionada m\u00e1s arriba. Segundo, 342.478 de ellas son \u00fanicas, lo que significa que 100.295 o sea el 22,65 % del total, fueron usadas por m\u00e1s de una persona.<\/p>\n

Aqui est\u00e1n la 10 contrase\u00f1as mas usadas del ataque a Yahoo:<\/p>\n

    \n
  1. 123456 = 1666 (0.38%)<\/li>\n
  2. password = 780 (0.18%)<\/li>\n

      9. verizon.net (0.68%)<\/li>\n
      10. bellsouth.net (0.64%)<\/li>\n<\/ol>\n

        Su tiene una cuenta Yahoo, deber\u00eda cambiar la contrase\u00f1a, solo para estar seguro. Adem\u00e1s, si usa la misma combinaci\u00f3n de direcci\u00f3n de correo y contrase\u00f1a en cualquier otra parte deber\u00eda tambi\u00e9n cambiarla.<\/p>\n
