Techniques Hackers may use for Maintaining Access

Various techniques and tools can be employed to establish and maintain access in a compromised system . Here are some common techniques used to maintain access and persistence:

Backdoors are covert methods of maintaining access to a compromised system or network . They provide a secret entry point that can be used by the attacker to regain control even if the original entry point is closed or patched . Backdoors can be created by modifying system files , exploiting vulnerabilities , or planting malicious code within legitimate applications or processes.


Rootkits are malicious software or components that aim to hide the attacker’s presence and activities within the compromised system . They often modify system files , processes , or system configurations to avoid detection by security tools or system administrators . Rootkits can include kernel – level components that provide the attacker with deep access and control over the compromised system.

Remote Access Tools - RATs:

RATS are software tools that allow remote control and administration of a compromised system . They provide a means for the attacker to access and control the compromised system from a remote location . RATs often include features such as file transfer , remote desktop functionality , and keylogging capabilities.

Malware Persistence Mechanisms:

Malware persistence mechanisms ensure that malicious code or processes continue to execute and maintain access within the compromised system . These mechanisms may include modifying startup configurations , creating scheduled tasks , or leveraging system services to ensure that the attacker’s code is executed every time the system boots or specific events occur.

Covert Channels:

Covert channels are methods used to communicate and exchange information between the attacker and the compromised system without being detected . These channels often exploit existing network protocols , such as DNS or HTTP , to bypass firewalls or intrusion detection systems . Covert channels can be used to issue commands , exfiltrate data , or receive instructions from the attacker.

It’s important to note that TEKYHOST use of these techniques will only be performed within the authorized scope of a penetration test and in adherence to ethical guidelines . Maintaining access and persistence will always be done with proper authorization and for legitimate purpose.
