Trace Labs is a not-for-profit organization that crowdsources open source intelligence (OSINT) to help authorities find missing persons.
Comprised of and led by volunteers, Trace Labs partners with other organizations and law enforcement agencies to set up Capture-The-Flag-type contests during which computer enthusiasts, infosec pros, first responders, hackers and private investigators compete by unearthing open source information that can provide leads for law enforcement to pursue.
