Target Exploitation & Privilege Escalation (Session 10 Summary)

🔬 1. Vulnerability Research Foundations

Programming: Code analysis using C/C++, Python, Perl, or Assembly.

Reverse Engineering: Analyzing compiled software binaries without original source code.

Instrumented Tools: Monitoring application runtime behaviors with debuggers and fuzzers.

Payload Construction: Engineering reliable shellcode execution pathways.

🗂️ 2. Public Exploit Directories

Public PoCs: Used by penetration testers to safely evaluate software version vulnerabilities.

Platforms: Exploit-DB , Packet Storm, SecurityFocus, NVD, US-CERT , Secunia , and XSSed.

🛠️ 3. Metasploit Console Basics (msfconsole)

Execution: Terminal interface tool for launching framework scans and exploits.

Global Show: Commands like show exploits or show payloads view platform-wide modules.

Contextual Show: Module-specific settings reveal options like show targets or `show advanced.

🚀 4. Privilege Escalation Mechanics

Vertical Escalation: Gaining higher system permissions (e.g., web user to root admin).

Horizontal Escalation: Lateral movement between accounts with matching privilege levels.

Vectors: Local kernel exploits, open home directories exposing stored SSH private keys, weak passwords, network sniffing, and packet spoofing.

🔐 5. Password Auditing Strategy & Tools

Online Guessing Attacks

Mechanics: Remote login attempts over production networks; limited by latency and lockouts.

Tools: Hydra, Medusa, and CeWL (web wordlist scraper).

Offline Cracking Attacks

Mechanics: Reversing stolen database file hashes locally on attacker hardware without network restrictions.

Tools: Hashcat, John the Ripper, Rainbow crack, Ophcrack, Crunch, and Hash-identifier.

🔄 6. Man-in-the-Middle (MitM) & ARP Spoofing

Normal Condition: Nodes exchange standard ARP requests and replies to map local IPs to hardware MAC addresses.

Spoofed Condition: The attacker broadcasts fake ARP responses to poison targets' cache tables.

Sniffing intercept: Traffic routes through the attacker to be read via Tcpdump, Wireshark, or Dsniff before forwarding.
