Doc Edward Morbius ⭕<p><strong>In Memoriam: Mark Klein, AT&T Whistleblower Who Revealed NSA Mass Spying</strong></p><blockquote><p>[W]hat Mark told us changed everything.

Mark was assigned to connect circuits carrying Internet data to optical “splitters” that sat just outside of the secret NSA room but were hardwired into it. Those splitters—as well as similar ones in cities around the U.S.—made a copy of all data going through those circuits and delivered it into the secret room.</p></blockquote><p><a href="https://www.eff.org/deeplinks/2025/03/memoriam-mark-klein-att-whistleblower-about-nsa-mass-spying" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">eff.org/deeplinks/2025/03/memo</span><span class="invisible">riam-mark-klein-att-whistleblower-about-nsa-mass-spying</span></a></p><p>Klein provided one of the pre-Snowden disclosures of massive communications surveillance in the United States.
