corpcrack 1.0.0

Corporate password list generator for internal security assessments

CorpCrack

CorpCrack is a targeted password list generator built for internal network assessments that produces organization-based, likelihood-sorted output.

---

Why not just use a wordlist?

Generic wordlists (rockyou, SecLists, etc.) have no awareness of the organization you are targeting. They will never contain the patterns that employees actually set.

CorpCrack generates a single likelihood-sorted list that serves two purposes. Towards the top of the list are the most commonly identified passwords, ideal for spraying within a lockout window. Further down, it transitions into company-specific and leetspeak patterns better suited for cracking, the kind of candidates that generic wordlists will never have.

Usage Examples

# Full engagement run, company context, year range, write to file
corpcrack -s ACME -l "Acme Corporation" --year-start 2022 --year-end 2026 -o passwords.txt

# Quick spray list, just the top 20 most likely passwords, no company context
corpcrack --top 20

# Target enforces a 10-character minimum password policy
corpcrack -s ACME --year-start 2024 --year-end 2026 --min-length 10

# Exclude passwords you already tried in a previous spray window
corpcrack -s ACME --year-start 2024 --year-end 2026 --exclude already_tried.txt

# Only output static and company patterns
corpcrack -s ACME --year-start 2024 --year-end 2026 --patterns static,company

# Generate with all common shift modifiers (!@#$%) instead of just !
corpcrack -s ACME --year-start 2024 --year-end 2026 --shift-modifiers common

# See how your weights are currently ordered
corpcrack --show-weights
corpcrack --show-weights --config corpcrack.toml

# Generate a default config, tweak weights, then use it
corpcrack --init-config
corpcrack -s ACME --year-start 2024 --year-end 2026 --config corpcrack.toml

How the output is sorted

Each pattern has a weight that controls where it appears in the list. Lower numbers appear first.

Pattern	Default	Examples
static	100	Welcome1, Password123!, keyboard walks
season_current	200	Spring2026!
month_current	250	April2026!
welcome_current	275	Welcome2026!
special	300	Winteriscoming2025!
company	400	ACME1!, ACME123!
company_current	450	ACMESpring2026!
welcome	500	Welcome2024!, Password2025!
welcome_company	550	Welcome2ACME2025!
company_year	600	ACME2024!, ACME@2025
season	700	Summer2024!, Winter2023!
company_season	800	ACMESummer2024!
month	900	January2024!, Oct25!
company_month	1000	ACMEJan2024!
leet_common	10000	W3lcom31
leet_multi	20000	W3l<0m31
leet_uncommon	30000	Wel{ome1

Patterns named *_current match the current season or month based on your system clock. Leet variants always appear below all non-leet passwords, following the same pattern ordering as their base passwords.

Custom weights

Generate a starter config:

corpcrack --init-config

This writes corpcrack.toml to the current directory. Edit the weights, then pass it in:

corpcrack -s ACME --year-start 2024 --year-end 2026 --config corpcrack.toml

Only the keys you include are overridden, everything else keeps its default.

Move a specific pattern higher in the list:

[weights]
company_season = 450

Disable the current-time boost. By default, passwords matching the current season/month rank higher. To treat them the same as any other season/month:

[weights]
season_current = 700
month_current = 900
welcome_current = 500
company_current = 800

Keep leetspeak variants out of spray range. Push them to the bottom of the list:

[weights]
leet_common = 999999
leet_multi = 999999
leet_uncommon = 999999
