Magecart injects JavaScript into your checkout to copy card details as customers type. The shop keeps working, the order completes, and nothing looks broken. Here is how it gets in and what actually reduces the risk.
MySQL moved away from MyISAM in 2010, but plenty of WordPress, WooCommerce and older store databases are still quietly running on it. Table level locking costs you exactly when you are busiest.
