Overview

Product summary

Review the store description, core capabilities, and common use cases.

The VT4Browsers extension is enhanced with Google Threat Intelligence (GTI) data, transforming it into a vital resource for enterprise security analysts.

Designed to streamline your browser workflow, the upgraded GTI extension integrates Google’s unparalleled threat intelligence—from Mandiant, VirusTotal, and Google’s core visibility—directly into your daily investigation process. Building on the foundation of the VirusTotal extension, this tool significantly reduces the operational overhead and context-switching typically required to investigate Indicators of Compromise (IoCs).

1. It automatically detects and enriches IoCs such as IPs, hashes, URLs, and domains on any webpage.

2. It provides immediate, at-a-glance Detection Ratio and GTI Enrichment Hovercard for instant triage and prioritization.

3. Analysts can dive deeper into suspicious assets by clicking to open the Integrated GTI Widget, which provides full attribution and reputation context in a seamless side panel.

4. It enables seamless collaboration and tracking of the IoCs on a webpage.

it really helps to know if the page is safe, but does not clean the page.

AI product read

Browser extension that automatically detects Indicators of Compromise (IoCs) such as IPs, hashes, URLs, and domains on webpages, enriches them with VirusTotal and Google Threat Intelligence data, and provides download protection by scanning files before they are saved

Reduces operational overhead and context-switching for security analysts investigating IoCs by embedding threat intelligence directly into the browser workflow, eliminating the need to manually query VirusTotal/Google TI for each indicator

User browses web pages normally → extension content scripts detect IoCs (IPs, hashes, URLs, domains) on pages → IoCs are highlighted with VT/GTI icons → user clicks an icon to open the AUGMENT widget in a side panel showing detection ratio, reputation, and full attribution → optionally, downloaded files are automatically scanned with VirusTotal/Google TI before saving → user can also right-click any URL/link to scan it directly via VirusTotal

Target users: Enterprise security analysts / Threat intelligence researchers / Security operations center (SOC) teams / Incident response professionals

Cannot fully determine the boundary between free-tier and paid-tier VirusTotal API features from source code alone
The extension uses an embedded/hardcoded API key for some functions (passive DNS), making it unclear exactly which features work without a user-provided key
The gtig-popup.js (48K) was not fully read but grep showed no login-related keywords

Monetization

No paid features detected

The extension itself is free with no billing, subscription, or payment system. It does not gate features behind payment. However, the destination service (VirusTotal/Google TI) has premium API tiers. When the user's API quota is exceeded (HTTP 429), the extension shows an error with a link to VirusTotal's premium-services contact page (_locales/en/messages.json lines 207, 211). One UI string also mentions quota limits of 20K requests/day for certain options (line 175-176). These are service-level quotas, not extension-level paid features.

Confidence: 80
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension's core IoC enrichment, highlighting, and AUGMENT widget features require a VirusTotal/Google TI API key. The options UI (src/options.html line 115) provides an API key input field, and without it, widget/enrichment/highlight options are disabled (options.js line 334-351). background.js line 1467-1471 sends 'API key not found' error when no key is set. Obtaining an API key requires registering on VirusTotal at https://www.virustotal.com/gui/join-us (_locales/en/messages.json line 163). However, the basic download scanning feature works without an API key using an embedded key (background.js line 1114-1115) and the vtMagic() token generator (line 836).
