Magento is a profitable target for hackers. Since 2015, I have identified more than 40.000 compromised stores. In most cases, malware is inserted that will a) intercept customer data, b) divert payments or c) uses your customers for cryptojacking. This project contains both a fast scanner to quickly find malware, and a collection of Magento malware signatures. They are recommended by Magento and used by the US Department of Homeland Security, the Magento Marketplace, Magereport, the Mage Security Council and many others.
