5️⃣Linux Post Exploitation

Uncover the advanced techniques employed by cybersecurity experts to navigate and control Linux systems post-compromise. Elevate your understanding of post-exploitation strategies, privilege escalatio

Understanding post-exploitation methodologies in a Linux environment is crucial for cybersecurity professionals.

Here's an overview of the Linux post-exploitation methodology:

Information Gathering

• System Identification: Identify the Linux distribution, kernel version, and other system details.

• User Enumeration: Enumerate users and their privileges on the compromised system.

Privilege Escalation

• Exploiting Vulnerabilities: Identify and exploit vulnerabilities to escalate privileges.

• Abusing Sudo Permissions: Exploit misconfigurations in sudo permissions to gain higher privileges.

• Kernel Exploits: Look for kernel vulnerabilities that can be exploited for privilege escalation.

Maintaining Persistence

• Backdoors: Install backdoors for persistent access.

• Cron Jobs: Create scheduled tasks for continuous access.

• SSH Keys: Add SSH keys for persistent remote access.

Lateral Movement

• SSH Tunnels: Establish SSH tunnels for accessing other systems in the network.

• Pass-the-Hash (PtH): Use compromised credentials to move laterally within the network.

• Exploiting Trust Relationships: Leverage trust relationships between systems to move across the network.

Data Exfiltration

• Compression and Encryption: Compress and encrypt sensitive data before exfiltration.

• Covert Channels: Use covert channels for stealthy data transfer.

Covering Tracks

• Log Tampering: Modify or delete logs to erase traces of the compromise.

• Clearing Shell History: Erase command history to hide executed commands.

• Rootkit Installation: Install rootkits to hide malicious activities.

Exploiting Services:

• Database Exploitation: Exploit databases for data retrieval and manipulation.

• Web Application Attacks: Identify and exploit vulnerabilities in web applications hosted on the server.

Resource Abuse

• CPU and Memory Usage: Exploit resources for cryptocurrency mining or denial-of-service attacks.

• Network Scanning: Scan the internal network for potential targets.
