Avoiding alerts

Just like in the preceding phases, it is in the interests of the hacker to avoid raising any alarms that the victim system has been compromised. Detection, especially at this phase, would be costly, as it would mean that all the efforts that an attacker had made will have been for nothing. Therefore, before the attacker performs this phase, it is normal to disable security systems if possible. The methods of privilege escalation are also quite sophisticated. Most of the time, the attacker will have to create files with malicious instructions, rather than use a tool to execute malicious actions against the system.

Most systems will be coded only to allow privileges to legitimate services and processes. Therefore, attackers will try to compromise these services and processes in order to be given the benefit of executing with heightened privileges. It is challenging for hackers to use brute force to get admin privileges and therefore they often opt to use the path of least resistance...
