Spammer 'bombs terrorism' globally

The cybercrime groups have been taking advantage of the system of kidnapped family PCs to bomb tons of mail bombs that paralyze the worldwide mail system.

Statistics from Postini, an e-mail security firm, said the number of global spam in November shot up to 7 billion, nearly three times that of June this year (2.5 billion). For every 10 emails sent, there are 9 email spam.

The situation will get worse when Christmas and year-end holidays are approaching. This time is considered the business season of business firms and is also the "business season" of the spam oligarchs.

" E-mail systems have been overwhelmed or stopped because they have to handle a large number of emails ," said Dan Druker, Postini's vice president.

The international anti-spam organization Spamhaus said that the US, China and Japan were the top oligarchs and said 80% of global spam is the product of about 200 notorious global spammer groups.

Experts say the sudden increase in spam volume is due to the spread of malicious software that kidnaps home users' PCs to build a so-called "zombie network." serve for spamming. A network like this can link 100,000 home PCs to send spam that users don't know.

Software that abducts PC to send spam is more and more dangerous thanks to the high level of hiding ability and the ability to send spam in huge quantities.

Not only is the spammer more and more cunning. They find ways to bypass spam filtering tools. It could be a change of keywords or an image for text.

With billions of emails sent like that, just a very small number of users responding to those emails is enough to bring a huge profit to the spammer.

The anti-spam law has not brought any satisfactory results. The United States is the first country to have anti-spam laws, while many other countries are still in the process of research and drafting.

Spam problem is an extremely difficult problem because it is an inter-national global problem. It requires close cooperation to be able to solve it thoroughly.

Some people argue that law and filtering tools are not enough to combat spam, but people. Dave Rand - expert of Trend Micro security firm - stressed that it is not a technology issue but a problem of ourselves. As long as we buy from spam ads, it will be spam.
