It was never built with authentication or encryption in mind. Security wasn’t part of the plan.  The assumption was simple:  All carriers are trusted.

Today’s Intel and AMD processors ship with embedded subsystems like the Intel Management Engine (ME) and AMD’s Platform Security Processor (PSP)—proprietary, low-level firmware environments that operate outside and below your main operating system.

]]> Why the Salt Typhoon Hacks Make Our Public Networks Vulnerable https://puri.sm/posts/why-the-salt-typhoon-hacks-make-our-public-networks-vulnerable/ Sat, 18 Jan 2025 18:39:34 +0000 https://puri.sm/?p=82719 The recent Salt Typhoon hacks by the People's Republic of China (PRC) have exposed significant vulnerabilities in our public networks. 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.
