Immersive Translate Trans

The extension loads additional code dynamically at runtime, which can make it harder to predict what functionality is active.

Technical: Code uses import() syntax for loading modules. This pattern allows for modular updates but may hide malicious behavior if not monitored carefully.

💡 Common in modern extensions that update features without full reinstallation.

The extension uses obfuscation techniques to hide code logic, which is often a red flag in potentially malicious software.

Technical: Found usage of String.fromCharCode and charCodeAt for decoding strings. This technique can be used to conceal URLs or payloads within the source code.

💡 Used by legitimate extensions for obfuscating internal logic or API keys, though it should be reviewed carefully.

The extension makes network requests to translate content using various translation APIs. This is expected behavior for a translation tool.

Technical: Uses both XMLHttpRequest (XHR) and the Fetch API to communicate with external services like DeepL, Google Translate, OpenAI, etc., sending page text or user input for processing.

💡 Standard practice in browser extensions that rely on cloud-based APIs for functionality.

The extension runs across all websites, meaning it has the potential to interfere with or monitor your activity everywhere you browse.

Technical: Content scripts are injected into <all_urls>, including file:///* and *://*/*. This means every page load triggers script execution, increasing risk of unintended interference or data capture.

💡 Required for real-time translation across any web content; however, it increases exposure to potential misuse if not properly sandboxed.

The extension has access to all websites and can potentially read or modify any data on those sites, which is a major privacy concern.

Technical: Permission includes <all_urls>, allowing unrestricted access to site content. If misused, this could enable surveillance or manipulation of user sessions or personal information.

💡 Necessary for real-time translation across arbitrary web pages; however, it should be limited where possible.

The extension can intercept and alter network traffic to translate content before displaying it. While useful for translation, this capability could also be misused.

Technical: Uses declarativeNetRequest APIs to block or modify requests. Could potentially inject ads, redirect users, or silently change page behavior if misconfigured.

💡 Used in many extensions that need to rewrite content or filter resources during translation workflows.

There may be hardcoded API keys or secrets within the extension code, which could pose a security risk if exposed.

Technical: Code inspection revealed possible references to hard-coded tokens. These should be reviewed for exposure risks and replaced with secure credential management methods.

💡 Common in early-stage development where developers sometimes commit test keys or temporary credentials.

The extension uses postMessage to communicate with other origins, which is standard for secure cross-frame communication but can be misused if not handled carefully.

Technical: Uses window.postMessage() for inter-origin messaging. If improperly validated or sanitized, could allow unauthorized access to internal data or control flows.

💡 Standard method in extensions that interact with embedded frames or external tools like translation APIs.

The extension sets up event listeners to respond to user actions and page events, which is normal for interactive browser extensions.

Technical: Uses standard DOM APIs like addEventListener to capture mouse hover or input events. These are typical in UI-enhancing tools but must be monitored for misuse.

💡 Essential for features such as real-time translation on hover and keyboard-triggered translations.
