In a recent story, NBC News spotlighted parents in Maine and Seattle who are reviving landlines for their children—creating “landline pods” so kids can connect without the addictive pull of screens or the predatory reach of social media platforms.

The SBOM is a comprehensive inventory of all components, libraries, and dependencies used in software development. This transparency is crucial for identifying potential vulnerabilities and mitigating risks associated with software supply chains.

These hacks, which targeted major telecommunications providers like Verizon, AT&T, Lumen Technologies, Charter Communications, Consolidated Communications, Windstream, and T-Mobile (although the later says that they prevented access to PII data) have shown just how susceptible our public communication systems are to sophisticated cyber threats. The hackers exploited weaknesses in unencrypted messages and phone calls, allowing them to gain access to sensitive data and even geolocate individuals. The compromise to the public networks may indeed have follow-on repercussions such as muti-factor authentication (MFA) via SMS texts but that is a subject for a future post.
