CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Penetration testers and red teamers targeting Microsoft environments need SprayingToolkit for its purpose-built attack chains against Lync, Skype for Business, and OWA; the modular design of Atomizer, Vaporizer, Aerosol, and Spindrift lets you chain attacks without rebuilding payloads between targets. The 1,557 GitHub stars and active maintenance reflect real adoption in assessments where off-the-shelf commercial tools either overkill the scope or lack the flexibility to handle hybrid authentication stacks. Skip this if you're looking for a polished UI or post-exploitation frameworks; SprayingToolkit is Python scripts, nothing more, and demands you understand what each tool does before running it.
