Syncopate

Overview

Executive Summary

Distribution and Technical Behavior

• Browser Hijacking: The PUP forcefully alters the browser's default search engine, homepage, and new tab settings. It redirects all search traffic through a specific portal controlled by the adware operators, allowing them to intercept queries and generate pay-per-click revenue.
• Ad Injection and Desktop Overlays: The software acts as a desktop widget, constantly pulling dynamic, unverified advertisements from remote servers. It can also inject banners, pop-unders, and sponsored links directly into the user's web viewing experience.
• System Alteration: To ensure it remains active, Syncopate creates persistent Scheduled Tasks and modifies the Windows Registry to automatically launch its ad-serving components upon system boot.

Risk Assessment

Mitigation and Removal Strategies

• Endpoint Scanning: Utilize a reputable enterprise-grade anti-malware solution to perform a deep system scan, targeting the Syncopate executables, hidden scheduled tasks, and persistent registry keys.
• Browser Remediation: Manually inspect and remove any unknown or unauthorized extensions from all installed web browsers. Perform a complete factory reset of the browsers to clear the hijacked proxy and search settings.
• Application Control: Enforce strict application whitelisting policies to prevent standard users from executing unapproved software installers that are the primary vector for this adware.
