William Denton<p>Michael Bazzell's books on privacy, security and <a href="https://cosocial.ca/tags/OSINT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OSINT</span></a> are fantastic resources, really thorough detailed coverage by an expert. Anyone who bought the e books would get updates for free, which was a great deal, but the hosting company is changing its terms and it seems it's all going to stop. I'd say buy the e books now while you can, if you're at all interested in this. They'll stay useful.</p><p><a href="https://inteltechniques.com/blog/2025/03/24/sendowl-terminating-free-ebook-updates/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">inteltechniques.com/blog/2025/</span><span class="invisible">03/24/sendowl-terminating-free-ebook-updates/</span></a></p><p><a href="https://cosocial.ca/tags/IntelTechniques" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IntelTechniques</span></a></p>
