Seg\u00c3\u00ban el estudio realizado por BitDefender sobre spam y phishing, entre enero y junio de 2008 el spam publicitario sobre falsos valores burs\u00c3\u00a1tiles ha descendido del 25% al 2%. Contin\u00c3\u00baa igualmente en descenso el antiguo spam intrusivo por im\u00c3\u00a1genes. <\/p>\n<p>Cuando hablamos de t\u00c3\u00a9cnicas o medios de propagaci\u00c3\u00b3n, el cambio m\u00c3\u00a1s representativo lo encontramos en el aumento de la cantidad de spam basando en texto, que ha alcanzado un 70% a lo largo del primer semestre del a\u00c3\u00b1o, mientras que en el mismo per\u00c3\u00adodo de 2007 s\u00c3\u00b3lo lleg\u00c3\u00b3 a un 20%. El spam por im\u00c3\u00a1genes contin\u00c3\u00baa su declive bajando al 3%, respecto a la cuota del 60% que alcanz\u00c3\u00b3 el a\u00c3\u00b1o pasado.<br \/>\nEl texto sin formato contin\u00c3\u00baa siendo el medio preferido para la distribuci\u00c3\u00b3n de spam mediante correo electr\u00c3\u00b3nico debido a su simplicidad, el poco espacio que ocupa y su alta versatilidad.<\/p>\n<p>El spam basado en texto sigue recurriendo a scripts automatizados para desordenar, reformular o sustituir palabras, mientras que el spam por im\u00c3\u00a1genes utiliza habitualmente contenido ofuscado. Otros tipos de spam, como los que adjuntan PDFs o archivos de v\u00c3\u00addeo y audio, han decrecido en popularidad, representando entre un 10% y un 15% del total de amenazas.<\/p>\n<p>Los intentos de phishing realizados durante el primer semestre del a\u00c3\u00b1o muestran una variaci\u00c3\u00b3n y crecimiento en cuanto a falsas entidades bancarias y clientes objetivos. La mayor parte de las falsificaciones creadas para dichos fines pertenecen a organizaciones financieras de los Estados Unidos y sus principales v\u00c3\u00adctimas son personas de habla inglesa residentes en EEUU, Gran Breta\u00c3\u00b1a o Canad\u00c3\u00a1. Sin embargo, durante las \u00c3\u00baltimas semanas, los investigadores de BitDefender est\u00c3\u00a1n recibiendo cada vez m\u00c3\u00a1s notificaciones sobre ataques perpetrados en Espa\u00c3\u00b1a, Italia y Francia. La mayor parte de los argumentos utilizados en dichos ataques todav\u00c3\u00ada posee una connotaci\u00c3\u00b3n negativa: amenazas de bloqueo o caducidad de las cuentas y petici\u00c3\u00b3n de datos del usuario para actualizar las cuentas apelando a motivos de seguridad.<\/p>\n<p>Fuente: DiarioTi<\/p>\n","protected":false},"excerpt":{"rendered":"<p>De acuerdo con BitDefender el spam ha sufrido grandes cambios en lo que se refiere a su contenido y medio de distribuci\u00c3\u00b3n durante la primera mitad del 2008.
