Citizen Lab expose deux campagnes de surveillance télécom via SS7/Diameter et SIMjacker

🔍 Contexte Publié le 23 avril 2026 par le Citizen Lab (Université de Toronto), ce rapport de recherche documente deux campagnes distinctes de surveillance télécom menées par des acteurs désignés STA1 et STA2, identifiés comme des vendeurs commerciaux de surveillance (CSV) opérant probablement pour le compte d’États. L’investigation a débuté fin 2024 suite à l’analyse de logs de pare-feu de signalisation mobile, en collaboration avec Cellusys, Telenor Linx, Roaming Audit et P1 Security.

The Citizen Lab Bad Connection: Uncovering Global Telecom Exploitation by Covert Surveillance Actors

Our investigation uncovers two sophisticated telecom surveillance campaigns and, for the first time, links real-world attack traffic to mobile operator signalling infrastructure. The findings expose how suspected commercial surveillance vendors (CSVs) exploit the global telecom interconnect ecosystem, leverage private operator networks, and conduct covert location tracking operations that can persist undetected for years.

Huh, I just learned that apparently ϕ is shorthand for diameter?

Oh, wait. I get it. Because it looks like a circle.

Except this installation manual I was reading was using φ! That doesn't look like a diameter anymore.

Engineers, I have questions.
