Based on a new study released by software maker McAfee's Avert Labs group, the technology used to cloak many different forms of malware, especially rootkits, is becoming increasingly complex and harder to detect...

Kaspersky...said it identified specific three proof-of-concept attacks being tested out by hackers, at least one of which could pose a challenging risk to network defenders. The program reportedly locates itself in a computer's boot sector and gains control of the device prior to the launch of its operating system. Because the attack is introduced in this manner, Kaspersky said, the program is able to modify many operating system functions...it still may be "extremely difficult" to detect any interception or substitution of system functions...

"The threats are constantly evolving; someone figures something out and within minutes it's being distributed. The malware writers are getting much smarter and faster at sharing information and realizing the profit in this," he said. "Rootkit.com and the others come off as wanting to educate the industry, but the problem is that posts on those Web sites are dropped directly into malware. These good guys are trying to regulate the information, but, unfortunately, it's being misused."
