Dark Web Tools

IACA Dark Web Tools is a resource portal maintained by the International Association of Chiefs of Police (IACA) that provides law enforcement and investigators with guidance, tools, and references for conducting lawful investigations on the dark web and anonymizing networks. It functions as a curated starting point for practitioners navigating dark web OSINT.

For law enforcement and authorized investigators, the IACA Dark Web Tools portal aggregates operational guidance and tool references that have been vetted for legitimate investigative use. This includes approaches for safely accessing Tor hidden services, techniques for correlating dark web identities with surface web activity, and guidance on evidence preservation standards for dark web sourced material.

The portal is particularly valuable for investigators new to dark web environments who need a structured, professionally endorsed approach rather than assembling ad-hoc tooling. It contextualizes dark web investigation within legal and procedural frameworks that matter for law enforcement, ensuring that evidence collected will withstand judicial scrutiny.

Common investigative scenarios addressed include: identifying and monitoring dark web marketplaces where illicit goods are sold, locating forums where stolen data, credentials, or malware are traded, tracing cryptocurrency payment flows referenced in dark web transactions, and correlating dark web personas with surface web identities through operational security failures.

The resource also provides guidance on documentation standards specific to dark web evidence — capturing Tor circuit information, recording .onion addresses with timestamps, preserving page archives, and maintaining chain of custody for evidence collected in environments where URLs and content are ephemeral.

Law enforcement investigators should coordinate with their agency's legal counsel before conducting dark web operations to ensure compliance with applicable surveillance and computer access laws.
