The news from Citizen Lab confirms something many of us have suspected: the systems we rely on for basic communication have been turned into surveillance tools. Two separate vendors exploited the core infrastructure of cellular networks, the Signaling System 7 (SS7) protocol and similar backends, to track and intercept data from victims around the globe. This isn't a theoretical risk or a future possibility. It is happening now, and it erodes the trust that makes modern connectivity possible.
For anyone who uses a smartphone, which is nearly all of us, this means the network itself can be weaponized. These vendors did not hack individual phones or trick users into clicking malicious links. They went straight to the plumbing of the cellular system, abusing protocols designed decades ago when security was an afterthought. The practical result is that your location, your call records, and even your text messages can be accessed by parties willing to pay for access. The victims in this case were likely targeted for political or corporate espionage, but the same vulnerabilities apply to anyone. If you are a journalist, an activist, or simply a person with sensitive business conversations, the network you trust to deliver those messages cannot guarantee their privacy.
This is where we draw a clear line. The vendors responsible are not rogue hackers; they are commercial entities selling surveillance capabilities to governments and private clients. They broke trust not by accident but by design, building products that rely on exploiting a known weakness in global telecommunications. The industry has known about SS7 vulnerabilities for years. Carriers have made incremental fixes, but the core problem remains: the system was built for interoperability, not security. Until the telecom industry treats network integrity as a fundamental requirement rather than an optional upgrade, these abuses will continue.
What should you do? First, recognize that end-to-end encryption is not a luxury, it is a necessity. Use messaging apps that encrypt your data by default, and treat any communication sent over standard SMS or cellular voice as potentially visible. Second, push your employer and your carrier to demand transparency about how they protect the network infrastructure. This is not a problem that individual users can solve alone. It requires collective pressure on the companies that build and maintain these systems. The breach of trust is real, but it does not have to be permanent, if we demand better.
