Since Chedot is based on Chromium, it inherits Chromium’s vulnerabilities. Using a version from 2018 or 2020 means you are browsing with thousands of known security holes that have been patched in modern browsers. This makes your system susceptible to malware, phishing, and remote code execution.
The earliest version recorded in software databases is Chedot 43.0.2345.348, which was a 32-bit build compatible with Windows XP. A user agent string shows Chedot 43.0.2357.402 was also used on WinXP systems. A 2017 Malwarebytes forum thread discussing its safety indicates that Chedot was already circulating as a Chromium-based browser during this period.
