Verizon shrugs at vulnerability, and other telecom blunders

The big carriers have had quite a month. Here's a rundown.

  • : Carnegie Mellon’s CERT/CC published a vulnerability disclosure: Verizon’s VoLTE calls lack mandatory IPSec encryption, which leaves users vulnerable to call hijacking, caller ID spoofing, denial of service, and manipulation of emergency calls. Verizon initially acknowledged the vulnerability and promised a fix, but then asserted that the requirements weren’t actually mandatory, and finally stopped participating in the disclosure process entirely and provided no evidence of any mitigation.
  • Speaking of dodgy carriers, : A whistleblower complaint, filed in 2020 by a former IBM VP of threat intelligence, alleges that IBM and AT&T were repeatedly breached by foreign state actors, including a China-nexus hacking group, and disclosed none of it to federal agencies. The alleged breach count is over 56,000 intrusions between 2013 and 2016.
  • Why are telecoms so insecure? It's a fair question. Our Chief Architect David Dunn breaks down exactly , and why so much of the legacy infrastructure was never designed with your privacy in mind.
  • : In an 8-1 ruling, the Supreme Court upheld the FCC's authority to fine the major carriers for selling customers' real-time location data to third-party brokers, who then resold it further down the chain. AT&T was hit with a $57 million penalty, Verizon with $47 million, and T-Mobile and Sprint together with roughly $92 million. The carriers had been fighting this since 2020.
  • In May, Verizon's new CEO Dan Schulman floated the idea of moving beyond four customer segments to hundreds of thousands of them. Telecom analysts call this "segmentation." We call it “using your data to figure out the maximum amount you'll pay, and charging you exactly that.
