When you centralize critical infrastructure—especially within sprawling platforms like SharePoint—you create a single, oversized attack surface that adversaries can exploit with devastating precision. This wasn’t just a technical failure; it was a cultural one.

]]> 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.
