CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers and red teamers running password attack campaigns will get immediate value from Weakpass; the free wordlist collections eliminate licensing friction while covering the major hash types and complexity sizes you'll actually encounter in engagements. The tool's lack of licensing overhead means you can deploy it across multiple operator machines without procurement delays. Skip this if your team needs integrated password spraying, cracking workflow automation, or multi-protocol attack orchestration; Weakpass is wordlists only, not a cracking engine or attack framework.
Penetration testers running Office365 red teams need o365-attack-toolkit because it automates the attack chains most frequently missed in manual testing: password spraying against MFA-less accounts, token theft via API manipulation, and lateral movement through shared mailbox permissions. The 1,116 GitHub stars and active maintenance reflect real adoption by practitioners who've replaced custom scripts with this toolkit. Skip it if your scope is shallow phishing simulations or if your client's O365 tenant has conditional access properly configured; the toolkit assumes weak or absent policy controls that limit its value in mature environments.
