Instead of sending spam or malicious code in large numbers, those who are controlling ghost computer networks (botnets) start spreading with slower traffic to avoid detection by security systems in businesses.

Security software firm BlackSpider (UK) said there is a large botnet involved in spreading 50 million spam messages a day, affecting at least 150,000 IP addresses.

As a result, spammers limit the risk of being detected. ' Hackers have realized that' firing 'a small amount of virus will help us better hide the intrusion detection tools. This actually has the potential to cause long-term and more serious hazards , 'Kay said, adding that software packages such as Send-safe.com used by spammers to control multiple devices. Calculate broadband connectivity in spreading spam. Most of these PCs are infected with some viruses like SoBig.
