Muchas veces nos hemos preguntado por qu\u00e9 demonios hay organizaciones que mandan spam: \u00bfQu\u00e9 ganan con eso? \u00bfAlguien cae en esos tontos avisos de venta de Viagra?<\/p>\n

Chris Kanich y un equipo de la Universidad de San Diego y el Instituto Internacional de Ciencia Computacional<\/a> decidieron averiguarlo, de modo que secuestraron un botnet y se pusieron a investigar. El equipo infect\u00f3 intencionalmente ocho computadores con un virus intermediario para interceptar las instrucciones que el botmaster enviaba a los PCs zombies.<\/p>\n

Luego, cambiaron esas \u00f3rdenes, convirtiendo a toda la red de bots en un zombie para la investigaci\u00f3n. En lugar de enviar el tr\u00e1fico (de los pobres incautos que creen los avisos de Viagra) al sitio del botmaster, los avisos del spam redirig\u00edan a un sitio armado por el equipo de Kanich. La web parec\u00eda una farmacia en internet aut\u00e9ntica, pero en lugar de cobrar de tarjetas de cr\u00e9dito y enviar pastillas de az\u00facar al que cay\u00f3 en la trampa, el sitio lanzaba un error al visitante, y contaba el n\u00famero de clicks.<\/p>\n

<\/a>De este modo, calcularon cu\u00e1nta gente ca\u00eda en la trampa y segu\u00eda los links que vienen en el spam. Tomando en cuenta el precio promedio de los productos ofrecidos y el porcentaje de gente que hac\u00eda click para comprar, los investigadores desarrollaron una ecuaci\u00f3n para calcular cu\u00e1nto pod\u00eda ganar un spammer, y llegaron a la conclusi\u00f3n de que, al d\u00eda, consegu\u00edan un promedio de US$7.000.<\/p>\n

Esta es la ecuaci\u00f3n:<\/p>\n

\"\"<\/a><\/div>\n

G<\/strong>: Ingreso diario (US$7.000)
\nE<\/strong>: N\u00famero de correos spam que un botmaster ordena enviar a los zombies (1,7 millones)
\nM<\/strong>: N\u00famero de PCs intermediarios (550)
\nD<\/strong>: Porcentaje de e-mails enviados (23,8%)
\nF<\/strong>: Porcentaje de mails que no fueron detenidos por filtros de spam (var\u00eda seg\u00fan el proveedor del servicio de correo)
\nV<\/strong>: Porcentaje de usuarios que hacen click en los links (F x V = 0,0127%)
\nB<\/strong>: Porcentaje de usuarios que compran un producto v\u00eda spam (0,266%)
\nP<\/strong>: Precio promedio de compra de un producto (US$100)<\/p>\n
