Study Notes
Introduction to System Hacking
- Gaining access to a target system using previously obtained information
- Attack surface: all points of entry and exit for a system (e.g., user interface, database interface, network interface)
- Ease of access depends on the target's attack surface
Attack Surface Evaluation
- What is a software product’s attack surface? Where are the control and data entry and exit points?
- How to measure it? Define a baseline and regularly measure and monitor changes.
Microsoft Attack Surface Analyzer
- Free tool for highlighting security issues in an application.
- Scans for open files, active apps, and Windows services.
- Compares scans against baselines to highlight potential vulnerabilities.
Password Attacks
- Password cracking techniques launched to crack encoded passwords.
- Password Salting adds randomness to passwords before hashing, making them harder to crack.
- Password Guessing Techniques include using dictionaries, names, addresses, and other personal information.
Password Security Risks
- Default or weak passwords are easily cracked, and often include easily guessed information like "admin".
- John the Ripper is a password cracking tool that supports many hashing algorithms and can crack various types of encrypted data.
- Ophcrack uses rainbow tables to crack passwords.
- THC Hydra is a fast password cracking tool that parallelizes network logins.
