Recommended Posts

o poder das botnets... milhões de PC´s infectados com clientes comandados por servers... será sempre "matando" o server que se para uma botnet... já que impedir que o comum dos mortais seja infectado é impossível

controlar uma botnet permite controlar milhares de PC´s para ataques coordenados... e para envio de spam... se calhar grande parte dos leitores se fizer um "c:\netstat -ab" se calhar vão ver muitas ligações remotas a uma porta 25 "SMTP relay server... servidor de envio de emails"

0 -b é para identificar o processo que está a estabelecer a ligação... caso vejam isso analisem logo o processo que está a comunicar com portas 25

há montes de pessoas a "matar" servers e parece que até a M$ faz isso... pelo menos que faça algo pela comunidade sem ser só "sacar" dinheiro

With the help of a U.S. federal judge, Microsoft has struck a blow against one of the Internet's worst sources of spam: the notorious Waledac botnet.

Microsoft said late Wednesday that it had been granted a court order that will cut off 277 .com domains associated with the botnet. This will effectively knock the brains of Waledac off the Internet, by removing the command-and-control servers that criminals use to send commands to hundreds of thousands of infected machines.

Thought to be used by Eastern European spammers, Waledac has been a major source of computer infections and spam over the past year. Microsoft believes the botnet can send over 1.5 billion spam messages daily.

In a lawsuit against the unknown spammers behind Waledac, filed Monday with the U.S. District Court of Eastern Virginia, Microsoft argues that Verisign, which manages the .com domain, is a choke-point for the botnet. The court has apparently ordered Verisign to remove the botnet's command-and-control domains from the Internet.

"This action has quickly and effectively cut off traffic to Waledac at the '.com' or domain registry level, severing the connection between the command and control centers of the botnet and most of its thousands of zombie computers around the world," Microsoft said in its blog post announcing the effort.
