Security Intelligence Report: Analysis of "http id codevn net chplay mobileconfig" Classification: Suspicious / Potentially Unwanted Program (PUP) Date: October 26, 2023 Subject: Mobile Configuration Profile Distribution Analysis

1. Executive Summary This report details the technical analysis of the URL pattern http://id.codevn.net/chplay/mobileconfig . This URL is commonly associated with the distribution of mobile configuration profiles ( .mobileconfig ) designed for iOS devices (iPhone/iPad). The domain codevn.net and its subdomain id.codevn.net have been flagged by various security researchers and automated threat intelligence platforms as suspicious. The URL structure suggests an attempt to mimic legitimate application stores (specifically the Google Play Store, known as "CH Play" in Vietnam) to social engineer users into installing unauthorized configuration profiles. 2.
