CST VerdictBased on our analysis of available product data, here is our conclusion:
Pentesters and bug bounty hunters looking to quickly identify subdomain takeover opportunities should reach for tko-subs; it's purpose-built for finding dead DNS records that expose attackers to domain hijacking, and the 766 GitHub stars reflect active use in offensive security communities. The tool excels at the reconnaissance phase where speed matters, automating what would otherwise be manual domain validation across hundreds of subdomains. Skip this if you need deeper DNS validation, certificate transparency correlation, or integration with broader asset discovery platforms; tko-subs does one thing and doesn't attempt the ecosystem around it.
Red team operators and security researchers validating defensive controls need Darkarmour because it's free, actively maintained, and lets you rapidly iterate obfuscation payloads without licensing friction. With 837 GitHub stars and active commits, it has real adoption among practitioners who need to test whether their AV actually detects what vendors claim. Skip this if you're building detection rules for a SOC; Darkarmour is offensive tradecraft, not a detection platform, and will frustrate teams expecting telemetry or an alert interface.
