Engagement brief

You are the security analyst running an authorized password-strength audit for Northwind Diagnostics. The blue team handed you a sanitized credential dump pulled from the staging host lab-vault01 and one encrypted evidence archive. Your job is to measure how fast weak passwords fall to an offline attack so the team can justify a stronger policy.

Everything you need is in the analyst home directory. A vetted wordlist lives at /usr/share/wordlists/audit-rock.lst. Type help in the console to see available commands, then work the task list on the right. When every target is cracked and every question answered, submit your report.
