New! Plugin Severity Now Using CVSS v3

The remote host has been compromised and is running a 'backdoor' program.


The remote host appears to be running a machine that is being used to control a botnet. A botnet is a network of compromised computers that are remotely controlled by a malicious bot administrator. Botnets are commonly used for
sending spam
running Denial of Service (DoS) attacks against other networks
scanning and compromising new systems
Installing sniffers
Installing keyloggers
Identify theft


Manually inspect the machine for malicious processes. In addition, you may wish to consider installing security software that detects and blocks this sort of malicious software.
