HyperFractius Browser Extension: Threat Analysis and Comprehensive Removal Guide

The HyperFractius browser extension is a potentially malicious program that exploits the “Managed by Your Organization” policy configuration feature in Chromium-based web browsers, such as Google Chrome and Microsoft Edge. This feature, designed for enterprise use by IT administrators to enforce corporate policies on managed devices, is manipulated by HyperFractius to gain unauthorized control over browser settings, leading to a series of intrusive and potentially harmful actions.

What Is the HyperFractius Browser Extension?

Type: Browser Hijacker, Redirect, PUA (Potentially Unwanted Application)
Also Known As: Finditfasts.com
Short Description: HyperFractius is a rogue browser extension that hijacks browser settings, redirects web traffic, injects advertisements, and collects browsing data. It leverages legitimate enterprise policy mechanisms to avoid easy detection and removal.

How HyperFractius Operates

Once installed, HyperFractius:

• Configures the browser to appear as if it is managed by an organization, granting itself elevated privileges.
• Alters the default search engine, redirecting users to suspicious or malicious websites.
• Injects advertisements into web pages, creating intrusive browsing experiences.
• Collects browsing data, potentially compromising user privacy.
• Locks certain browser settings to prevent users from making changes.

Its deceptive use of legitimate enterprise policy settings makes detection challenging, even for tech-savvy users. The extension’s persistence mechanisms often leave users struggling to regain control of their browsers.

Symptoms of HyperFractius Infection

• Appearance of the “Managed by Your Organization” message in browser settings.
• Default search engine changed to an unknown or suspicious provider.
• Frequent redirects to unwanted websites.
• Sudden influx of intrusive pop-up advertisements.
• Restricted access to browser settings.

How to Detect HyperFractius Using Chrome Policies

Fake extensions like HyperFractius often introduce custom Chrome policies that restrict browser functionality. To check for these policies:

1. Open Chrome and type chrome://policy/ in the address bar, then press Enter.
2. Review the listed policies. Look for any unusual entries, particularly those controlling extensions or search engines.
3. If you find unfamiliar or suspicious policies, it’s likely that a malicious extension like HyperFractius has introduced them.
