Last weekend at the Mage Titans Conference in Manchester, the sansec folks announced their new Composer Integrity Plugin project.

This plugin for Composer checks all installed composer packages against a list of known correct checksums which are provided by Sansec. This helps to quickly verify the integrity of the installed Composer packages.

Installing the Composer plugin is done like this:

composer require --dev sansec/composer-integrity-plugin

Once the plugin got installed, you can run the integrity check as follows:

composer integrity

A scan result report output looks like this:

+--------+-------------------------------------------------------------------+-----------+------------------+------------------+------------+
| Status | Package                                                           | Version   | Package ID       | Checksum         | Percentage |

Besides the status column, the percentage column gives you an indication of how many installs of the same package known by sansec have the same checksum.

A few days ago, a Magento module was released to run automated checks in the background. The scan results are either visible in the Magento Admin UI or sent to you via email.
