The FBI’s Denver Field Office recently issued a warning about a rise in malicious online file converter scams. These websites appear to offer free file conversions—PDF to Word, JPG to PNG, and so on—but instead deliver malware, aiming to compromise users’ devices and steal sensitive data.

‍

While the threat may seem consumer-focused on the surface, it’s increasingly relevant in the enterprise. Employees often use personal tools to complete work-related tasks, especially when no sanctioned alternative exists. That includes converting files using web-based tools that fall outside corporate IT controls.

Why It’s a Growing Security Gap

These fake converter sites take advantage of user intent and lack of visibility. They frequently use paid ads to appear at the top of search results and may not raise flags with traditional URL filtering or domain reputation systems.

‍

The larger issue is that existing network, email, and endpoint controls weren’t built to monitor what’s happening inside the browser. That includes behavioral context—like whether a user is interacting with suspicious downloads, submitting files to unsanctioned platforms, or installing risky extensions.

How Keep Aware Reduces This Risk

Keep Aware is designed to address this exact scenario. As a browser-native security platform, we provide real-time visibility and control over user activity, without disrupting the user experience.

‍

Here’s how we help prevent incidents like this:

• Real-Time Download Visibility and Risk Scoring: We detect and assess file downloads directly in the browser, identifying when users access potentially harmful or unknown converter tools.
• Contextual Warnings and Policy Enforcement: Users are alerted before risky actions—like downloading from suspicious sources—take place. Organizations can define custom file-handling policies based on user identity, risk profile, or context.
• Monitoring Upload and Data Transfer Behavior: We provide visibility into file uploads and sharing actions, which helps identify when sensitive data is submitted to unsanctioned or untrusted tools.
• Granular Governance Across Personal and Work Contexts: Employees often blur the line between personal and business use. Keep Aware distinguishes between individual and corporate browser identities, applying different security policies to each.

This recent FBI alert is another reminder that the browser is now a critical part of the enterprise attack surface—and one that needs dedicated attention.
