No one writes a book alone. And for me, writing a book about Russian intelligence was not without considering the risk. But this has been a life-long mission, and many helped me -and that same mission- along the way.
๐I want to take a moment to thank those who supported, and to celebrate with our BOOK LAUNCH MONTH!
๐My deep appreciation to all those below who have endorsed officially but also helped in so many other ways. Below are just a few I want to thank, with just some of the endorsements. Am in all your debt and @NavalInstitute for publishing me.

Please consider ordering if you haven't, USNI is already shipping, Amazon in a couple of weeks and in bookstores 21 April!
๐ My appreciation to these senior intelligence community, CIA leaders (including two former Deputy Directors), military, academics and others who have endorsed:
๐ Tradecraft, Tactics and Dirty Tricksย presents a very comprehensive study of Russian espionage and subversion tactics and modus operandi. It will serve as an indispensable handbook for national security professionals, students of Russian government and history and international affairs, and readers in the general public interested in the topic.
- From the book Foreword, by
๐จMichael Sulick, Former CIA Deputy Director for Operations, and Director of the National Clandestine Service
๐ Essential reading for practitioners, policymakers, and citizens alike who want to understand (and perhaps resist) Putin's secret war.
๐จ- Jennifer Ewbank, Former Deputy Director of CIA for Digital Innovation
๐Hard to put down, and harder to forget when falling asleep at night.
- John Nagl, author ofย Learning to Eat Soup with a Knife: Counterinsurgency Lessons from Malaya and Vietnam
๐Sean's book is an outstanding contribution to our understanding of the tradecraft utilized by what remain our most professionally skilled intelligence adversaries: the Russian foreign intelligence and security services.
- Former CIA Chief of Counterintelligence Mark Kelton
๐Filled with authoritative and compelling detail, welcome clarity, and insightful nuance, Wiswesser's book is required reading for any policymaker, intelligence officer, academic, or businessman dealing with Russian issues.
-ย Paul Kolbe, Former Chief CIA Central Eurasia Division, Senior Fellow at Harvard Belfer Center
๐An excellent book about the RIS and the threat they pose to the West. It is informative, approachable, and compelling. Written by a true expert, it should be mandatory reading for everyone in the U.S. IC.
- Robert Dannenberg, Former CIA Central Eurasia Division Chief/Chief of Russian Operations
๐Encounters with Russian officers add authenticity to his narrative that is rare in books about Russian intelligence.
- Kevin Riehle, Lecturer in Intelligence, Brunel University
๐Lifts the lid on the inner workings of the Russian security services.
- Gregory Sims, former CIA Station Chief

The Russian SIGINT/SATCOM station in Vienna is intercepting C-band communications from the Eutelsat 3B, Eutelsat 10B, SES-5, and Rascom QAF1 satellites, which serve Africa and connect to UN offices, embassies, oil fields, and military bases.
Thatโs not all. Olymp-K2, a Russian satellite capable of proximity operations (RPO - Rendezvous and Proximity Operations), is performing unusual maneuvers instead of remaining in a fixed orbital position. RPO enables it to approach Western satellites, monitor them, and even disrupt their functioning, seize control of them, or sabotage them.
Owing to its close proximity, Olymp-K2 can intercept unencrypted command-and-control signals used to manage satellite positioning, antennas, and data handling. A kinetic anti-satellite strike, or close-proximity operations used to disable or seize control of a satellite, could, depending on their scale and effects, amount to a prohibited use of force and, in an extreme case, potentially an armed attack.
The entire operation appears to be tightly coordinated - the station in Vienna intercepts data from ground links, while Olymp-K2 targets command-and-control signals in outer space. Together, they form a two-layered espionage network, giving Russia deep access to Western military and diplomatic communications in Africa.

๐จBREAKING: This Python tool reverses pixelation and recovers the original text from "censored" screenshots.
It's called Depix. You pixelate a password. Depix reads it anyway.
No AI model. No GPU. No cloud service. Just math.
Here's how it works:
โ You feed it the pixelated screenshot
โ It generates a search image using a De Bruijn sequence
โ Matches each pixelated block against known character renders
โ Uses geometric proximity to eliminate false positives
โ Reconstructs the plaintext character by character
Here's the wildest part:
It was originally built because someone pixelated a Domain Admin password in a corporate screenshot. The kind of credential that controls an entire company's network. Depix cracked it.
Every redaction tool you've ever used. Greenshot, Gimp, Snagit. If it uses a linear box filter for pixelation, this tool can reverse it.
The original repo hit 26,152 GitHub stars before the creator reset it. That's how hard this blew up.
Think about every screenshot you've ever shared with "censored" credentials, API keys, emails, or private messages.
If you pixelated them instead of using solid black bars, they were never hidden.
One command to run. Pure Python.
100% Open Source.

It was a huge counterintelligence win. Using Brazil as a launchpad shows how deep Russiaโs sleeper strategy runs- but once the cover stories crack, the whole network gets exposed. Quiet work, big impact.

Dear Claire, instead of blaming the "Open Internet," perhaps you should direct that frustration toward your own transponders screaming ADS-B data across every ocean. ๐ฐ๏ธโ๏ธ
โWe aren't hacking "classified systems." We are simply watching your "stealth" assets leave digital footprints louder than a sonic boom in a library. If data broadcasted to the entire world is considered "highly classified" by your standards, the issue isn't the amateur analystsโitโs an OPSEC strategy that seems stuck in 1995. ๐คทโโ๏ธ๐ฑ
โA pro-bono tip:
If your intercontinental movements show up on a flight-tracking app used by a teenager in his basement, that's not a "security challenge." That's you leaving the porch lights on and wondering why people can see you. ๐
