The Digital Sherlocks Summer 2026 program, delivered by the Atlantic Council’s Digital Forensic Research Lab (DFRLab), brought together participants from around the world working in civil society, media, academia, and independent journalism and research. The 2026 cohort included 529 participants from 82 countries. Over the course of the three-month online program, twenty-nine sessions were delivered. Modules covered skills including developing an investigative mindset, defensive writing, platform-specific investigations (i.e., Facebook, TikTok, X/Twitter, Telegram, YouTube), verification, geolocation, digital security, and AI-assisted research methods. The program was led by DFRLab's team of experts in open-source investigation, disinformation research, and verification. For the first time, the program also partnered with Penn MEDIATED at the University of Pennsylvania, which complemented the curriculum with academic depth on auditing AI systems, misinformation correction, and research in censored environments. Guest experts from Clemson University's Media Forensics Hub, the Internet Archive's Wayback Machine, DoubleThink Lab, and BBC Verify added further specialized perspectives, from coordinated campaign detection to digital archiving. The program also offered networking sessions, designed to encourage community building, collaboration, and cross-border investigations between participants Participants who attended at least three training sessions (excluding welcome and closing events, and networking sessions) and stayed for at least 75% of the duration of each of those sessions were eligible to request a certificate of participation, which specifies the skills they each gained. Since 2019, DFRLab’s Digital Sherlocks program has equipped over 4,000 participants from 140+ countries with cutting-edge tools and methodologies to combat disinformation and information manipulation—all at zero cost to participants. At a time when democratic norms face unprecedented challenges, the DFRLab's capacity-building programs ensure that local communities have the skills, connections, and confidence to protect their own information environments.
