OSINT Techniques: 10th Edition

This book was replaced by the current version of OSINT Techniques (11th Edition). Much of the content here is redundant and outdated. Some readers have requested that we offer this book which is technically "Out of Print", as it offers alternative content and flow. However, this comes at the cost of potentially outdated information. For most readers, we only recommend the "Current Books", but respect that some may want this version as a supplement to the current edition.
