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.
