Verizon confirmed a nationwide wireless service disruption that temporarily limited affected devices to SOS-only functionality. Service has since been restored, though no root cause has been disclosed.

While not a security incident, outages at this scale are relevant to:
- Availability and resilience planning
- Dependency risks in mobile infrastructure
- Business continuity considerations

How do organizations factor large-carrier outages into resilience planning?

A communications failure disrupted air traffic operations across Greece, grounding and diverting flights for several hours. Officials report no evidence of a cyberattack, with technical and judicial investigations underway.

The incident reinforces the importance of resilience engineering, redundancy testing, and modernization in safety-critical systems - alongside cyber defense.

From an infosec and resilience standpoint, where should investment be prioritized?

Are ships today more vulnerable to cyber attacks due to increased connectivity to their systems?

🚢 In our latest blog post, Andrew Tierney explains the potential risks associated with systems such as the Power Management System (PMS)⚡ and Integrated Alarm and Monitoring System (IAMCS), which are responsible for controlling the power generation and other machinery onboard.

⚠️ The consequences if these are hacked? Blackouts, increased crew workload, and potential loss of control during manoeuvres - especially risky in busy waterways. While hackers taking full remote control of a vessel is unlikely, disruptions to these systems are a genuine concern due to rising automation and inadequate network segmentation.

🛳️ Dynamic positioning vessels and cruise ships have even more complex, integrated systems. Inadequate network isolation among systems like dynamic positioning, safety management systems, and voyage data recorders can allow a hacker to impact multiple systems at once, making recovery far more challenging.
