Scheduled Jobs and Scheduled Tasks

One of the simplest ways to maintain access to a system is via a scheduled job or task using the techniques we reviewed earlier in this chapter. An advantage of a scheduled action is that it can allow recurring callbacks to a remote system rather than requiring a detectable service to be run. This is the same reason many botnets rely on outbound SSL-protected calls to remote web servers for their command and control. Using a secure protocol for the remote connection and ensuring that the system or systems to which the compromised host connects are not easily associated with the penetration tester’s activities can help conceal the compromise...
