Security vendor McAfee warned that rootkits are becoming more and more malicious. They are an effective "henchman" to help hackers hide many other malicious code.

McAfee's latest report said the complexity of rootkits is growing at an unusual rate. In just five years the number of components made up of rootkits has increased from 27 to 2,400.

Now rootkits can help hide deep and harder to detect malicious code on Windows-based systems.

McAfee: Rootkits are more and more unique images 1 " Today's use of rootkits is similar to the trend of using A rootkit before. However, rootkits are becoming more and more dangerous. Each malicious code seems to have its own rootkit ," said Dave Marcus - Director. Research and media director of McAfee - said. " Hackers now have more ways to hide their malicious code ."

However, security companies have been improving security software that can detect rootkits today. Some rootkit detection techniques are being used by applications such as active memory scans or from Trojans or viruses themselves and the location of rootkits.

This helps explain why the number of rootkits found in malicious code has decreased significantly over time. From the first quarter of 2006 to the end of the first quarter of this year, the number of rootkits has decreased by 15%.
