According to researchers, the number of computers controlled by botnets has exploded in recent months. According to the Shadowserver Foundation of the network security monitoring organization, according to the latest data records, the number of computers infected with botnets has quadrupled over the past 90 days.
Although the growth rate has declined slightly, there is enough evidence to convince researchers that the current botnet scale is so large that it is very profitable and rooted in the market.
In addition, although few or almost no new malware and viruses have been added, the number of computers infected by the Internet has increased, especially those vulnerable to SQL injection attacks.
Sans researcher John Bambenek pointed out that the increase in the number of botnets seems to be in line with the emergence of large-scale SQL injection attacks, in which thousands of web pages are injected with malicious code.
Bambenek said that security agencies lack a mechanism to effectively clear the SQL virus, resulting in large-scale proliferation.
He explained, "the lack of uniform standards to measure web pages makes it difficult to identify which websites are infected with viruses. "
"One disadvantage of man-machine interactive operations is that we are always after the problem arises, and this disadvantage will not be eliminated until we find a solution ."
