Most small businesses have been building a public intelligence profile for years without realising it. Every LinkedIn update, team photo, and website contact page adds detail to a picture that anyone can view, including those with malicious intent. This episode examines open source intelligence (OSINT) and how publicly available information becomes the foundation for targeted attacks like spear phishing and invoice fraud. Noel Bradford walks through the reconnaissance process, from Companies House filings to social media posts, demonstrating how an attacker can map your business, identify key staff, and craft convincing impersonation emails in under twenty minutes. The episode provides practical steps for auditing your own digital footprint, including what to check on search engines, how to review your Companies House entry, and why listing every software tool on LinkedIn might not be wise. This is not about disappearing from the internet; it is about making conscious choices about what you publish and understanding who else is reading it.

• Welcome Introduction to the concept of OSINT and how small businesses inadvertently publish reconnaissance material about themselves through normal business activities.
• Body A detailed walkthrough of public information sources including Companies House, LinkedIn, business websites, and social media. Explains how attackers use this data to construct targeted spear phishing campaigns, with practical examples of reconnaissance leading to invoice fraud and credential theft. Concludes with five actionable steps for auditing and managing your business’s public profile.
• Outro Final reminder that OSINT is simply reading publicly available information with intent, and that small businesses can reduce risk by auditing their own footprint and making conscious publishing decisions.
