Unit 03110 (1975): The oldest insignia linked to this unit features symbols such as tropical palms and a flag that confirm that it was previously stationed in Lourdes (Cuba), before being relocated close to Sotchi (Russia) in the late 2000s. Among the ten bases we have identified, this one is the only one that equipped its antennas with radomes designed to protect the equipment from weather and hide its orientation and specifications from unwanted eyes. These domes, which may contain a radar or a dish antenna, are even depicted on one of the unit's insignia, which also portrays the facility facing the sea, with mountains in the background.

Unit 61608 (1918): The unit's insignia frequently feature symbolic representations of Moscow, including the Kremlin. The unit hosts more than a dozen parabolic antennas near the T-shaped control building, as well as pole antennas arranged in an antenna array slightly further north. It is situated south of Tsaritsyno Park, concealed within a dense forest in the heart of Moscow.

Each interception centre also has a unique way of depicting itself through its insignia, as can be seen in these two examples from our report.

How the 16th Center depicts itself: The standard format of the shield and sword, symbols inherited from the KGB ; The Russian coat of arms (a double-headed eagle clutching a scepter and an orb surmounted by a cross, representing imperial authority and the Orthodox Church, respectively) ; A red background, a colour traditionally associated with the FSB.

The Center portrays itself in two distinct ways: A terrestrial globe featuring the Russian Cyrillic letter "i". This letter is commonly associated with the Russian word "information" in Soviet and Russian security services, and could be a reference to the information the unit is capable of acquiring ; An antenna positioned next to a key being shattered by a lightning bolt. The antenna is a fairly common symbol of radio transmissions, but is also used to represent signals intelligence (SIGINT).  The lightning bolt symbolizes the interception, disruption, and manipulation of enemy communications and radar systems.  The key shattered by the lightning bolt is highly likely an explicit reference to cryptanalysis, the branch of cryptography dedicated to breaking codes and cryptographic systems.

Thanks to phaleristics, we were able to gain insight into the unit's current
symbolism.

For over a year, we have collected and analyzed hundreds of photographs of military insignia linked to the 16th Center of the Federal Security Service of the Russian Federation (FSB).   We combined phaleristics (i.e. the study of medals, orders, decorations, and related honors issued by states, organizations, and military bodies) and traditional OSINT techniques to get insights into the history of the 16th Center, piece together part of its internal structure, and geolocate several of its interception centers within Russia.

During our research, we identified:  40 distinct insignia corresponding to different departments ("upravleniya") within the 16th Center.  10 departments within the 16th Center with at least 560 employees.   10 SIGINT stations composing a ground-based network highly likely operated by the 16th Center. These "Special Communications Centers" (TsSS) are designated either by a five-digit identifier or a number.

To unveil the infrastructure of the 16th Center, we employed a combination of unusual and traditional OSINT techniques. Our primary sources were hundreds of photographs of Russian insignia available on specialised websites.

🚨 #HEAT shows climate disinfo is systemic – but EU regulation hasn’t caught up.

Platforms still face no legal obligation under the #DSA to address it.

👉 It’s time to treat #ClimateDisinfo as a real threat to democracy.

Operation Overload: An AI fuelled escalation of the Kremlin-linked propaganda effort - CheckFirst The Russian propaganda operation targeted at media organisations and fact-checkers is still going strong. Operation Overload, which we first documented in June 2024 is now leveraging AI generated content, impersonation techniques and is expanding to more platforms such as TikTok and BlueSky. Telegram and direct emails to newsrooms remain a daily dissemination technique used to attempt to create a sense of urgency amongst their targets. Since we last published an update about the operation last September, some legitimate outlets regularly fall in the trap.

Over 180 individuals and organisations have been impersonated using AI-generated content in an attempt to cause confusion, manipulate debate, and overload fact-checkers. Despite that, platforms’ responses remain worryingly uneven.

Since September 2024, we have recorded over 700 targeted emails and nearly 600 unique pieces of falsified content disseminated across platforms including Telegram, X, BlueSky, and most recently TikTok.
