How to Scan Your Magento 2 Store for Malware (Free, in Under a Minute)

By W3ctrl Services · June 5, 2026

Magento and Adobe Commerce power some of the biggest online stores in the world — which is exactly why they're a favorite target for attackers. Card-skimming malware, webshells and unpatched vulnerabilities can sit on a store for months before anyone notices. The good news: you can check your store in under a minute, free.

Why Magento stores get hacked

Most Magento compromises trace back to one of three things: an unpatched version (a known CVE the attacker simply exploits), a vulnerable third-party extension, or weak admin security. Once in, attackers inject JavaScript skimmers into checkout pages or drop a webshell to keep access.

Step 1: Run a free external scan

Go to MageArgus and enter your store URL. It performs a passive scan — only looking at publicly available pages, like a search engine — so there's no risk and nothing to install. In seconds you get a 0–100 security score covering your version and matching CVEs, skimmer indicators, TLS and security headers, and publicly exposed sensitive files.

Step 2: Read your score and findings

Each finding is ranked by severity with a plain-English explanation and a copy-paste fix. A score under 75 means meaningful gaps; criticals should be handled immediately.

Step 3: Go deeper if you own the store

An external scan can't see inside your server. For a complete malware scan — file system, database, on-disk patch confirmation — install the MageArgus module, which scans from within your store and monitors it daily.

What to do if malware is found

Act fast: take the store to maintenance mode, change admin passwords, and get professional help. W3ctrl's Magento malware removal service cleans injected code, removes webshells, closes the entry point, and restores trust.

Make it a habit

Security isn't one-and-done. Scan after every deployment, every extension install, and at least monthly. A free MageArgus account lets you track all your stores in one dashboard and get alerts when something changes.
