Linux users' lack of security awareness leads to the spread of botnets

The Service Investigation and Research Report provided by Symantec, an Internet security enterprise, reveals that enterprises' users' lack of awareness of Linux email server security is a convenient way to spread "botnet virus, in addition, many users running Linux operating systems are infected with "botnets.

The monthly information reports provided by Symantec's Intelligence Lab indicate that, in the personal computer that sends Malicious spam emails, the number of PCs in Linux is five times that in Windows.

Matnisbet, a malware data analyst at the semen benchmark hosting service, posted the message on his personal blog, it also claims that it plans to explore the underlying causes of this phenomenon. "We conducted a random sampling test on computers that are infected with the virus and run Linux operating systems to test the IP address source that is infected with the virus," he said. In most cases, the IP address source points to a server that runs the open source email proxy service. This shows that many Linux operating system computers are infected by the "zombie virus" mainly because enterprise users operating their own email servers use open-source software to reduce operating costs. However, these enterprise users do not understand that the use of open-source software provides an opportunity for botnets to spread over port 25 ."

Nisbeth also pointed out that some "botnets" on the Internet can automatically search for email servers and PCs with port 25 open, these e-mail servers and PCs that use open-source software are infected with "botnets. "Any user who uses the free advantage of Linux software needs to be vigilant against operating system security. Use Correct security settings to protect personal computers from malicious "botnets. Individual users running the Linux operating system need to improve security settings and only provide authorized users with port 25 access permissions.
