    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.
