Which Magento versions do you clean?

We clean and harden Magento 2.4.4 through 2.4.9 (Open Source and Adobe Commerce), and we can triage end-of-life 2.3.x and legacy Magento 1 stores too. End-of-life versions no longer receive security patches, so for those we’ll clean the current infection and then strongly recommend an upgrade path, staying on an unpatched version means the next exploit is only a matter of time.
