When the Source Attacks Back: Prompt Injection Is Coming for OSINT
AI can help investigators move faster. It can also be manipulated by the sources it reads. This practical guide shows how prompt injection enters OSINT workflows, how to detect hidden instructions in webpages, PDFs and spreadsheets, and how to preserve, test and report the evidence. Includes a hands-on CTF lab with three realistic files to investigate.
