Password Cracking Tool · Hacking Project

Enable a student to understand password-hash cracking mechanics and translate them into stronger credential and hashing policy.

**The problem**
Weak and reused passwords remain a top breach vector, yet many organizations cannot quantify how resistant their credential store actually is to offline cracking. Security teams need to audit password strength and validate hashing/policy choices before attackers do. Understanding cracking mechanics is essential to both defensive password policy and authorized red-team credential assessment.

**What you'll build**
Build an educational password auditing tool that demonstrates dictionary, brute-force, rule-based, and mask attacks against common hash types (MD5, SHA-family, bcrypt, NTLM), leveraging Hashcat/John concepts and highlighting why slow, salted hashes resist cracking. Use it in an authorized lab to audit sample hash dumps and report weak credentials and policy gaps. The deliverable pivots offensive knowledge into defensive password-policy hardening recommendations.

**Objective** — Enable a student to understand password-hash cracking mechanics and translate them into stronger credential and hashing policy.

**Expected outcome** — A password-auditing tool plus a report ranking hash resistance and recommending policy/hashing hardening (bcrypt/Argon2, MFA, length).

**Difficulty** — Beginner — scriptable with existing libraries, though attack-mode depth and hash internals reach Intermediate.

**Framework alignment**
• MITRE ATT&CK: Credential Access — Brute Force (T1110), Password Cracking (T1110.002), Password Guessing (T1110.001), Credential Access from OS Credential Dumping context (T1003)
• NIST CSF 2.0: Protect (Identity Management/Authentication), Identify (risk assessment of credentials)

• CIS Controls v8: 5 (Account Management), 6 (Access Control Management), 16 (Application Software Security — credential storage)

**Innovation** — Existing Idea — cracking tools are ubiquitous; the differentiator is the auditing/defensive-policy framing and multi-hash resistance benchmarking. Scores: Innovation 4/10, Startup 3/10, Enterprise-Readiness 4/10, Patent = No.
