Flushing Magento 2 Varnish Like a Pro

Flushing Magento 2 cache is simple right? Just click the Orange “Cache Clear” button in the Admin, or run php bin/magento cache:clean from the command line. Speaking to other developers and merchants, this seems to be the way everyone deals with refreshing cached content. Even if its just affecting a single page or product. It does not take a genius to realise flushing the entire Magento cache, means a significantly lower cache hit rate for the short term....

How to delete spam customer accounts in Magento2

Summary Over the last few years, we’ve noticed an increase in the complexity of spam bots signing up to Magento 2 stores. They used to just spam customer accounts using the same email/email domain likely on ending in .qq.com .ru etc. So it used to be easy to just bulk delete based on the TLD especially for sites that do no ship to China / Russia etc. Whereas the last few years I’m observing them using standard mail providers such as gmail....

Anonymizing Magento 2 Databases with Warden

You might find yourself needing to anonymize a database in Warden to either pass off to another developer, or move it forward into ephemeral / staging environments. This is fairly easy to achieve with Smile-SA GDPR Dump. First lets download the resources we need, we will store them in the dev folder as we can exclude this in our deployment pipelines. wget https://github.com/Smile-SA/gdpr-dump/releases/latest/download/gdpr-dump.phar -o dev/gdpr-dump wget https://raw.githubusercontent.com/Smile-SA/gdpr-dump/main/app/config/example.yaml -o dev/gdpr-dump.yaml chmod +x dev/gdpr-dump Next we can edit the yaml to set our correct Magento version and catch any non core tables we might have followed by running the anonymizer script....

Analyzing a real Magento 2 Stripe CC Scraper Malware Sample

Overview Recently I came across a Magento 2.3.4 store with a stripe specific credit card scraper embedded into the checkout page. The Malware had been injected into the core_config_data table, and was being saved against the shipping/shipping_policy/shipping_policy_content key. The updated_at time of the entry was 2024-04-10 13:27:32 although its worth noting, whilst this may be the time of the initial infection. Since the original entry point has not been patched, an attacker could have simply changed the payload on that date....

Magento 2 Malware Analysis

Recently I onboarded a new client, who was looking for a new development partner. The site was running 2.3.4, so I was expecting we would need to perform a few updates and for there to be some security holes to patch. I ran Ecomscan, as always, during my initial audit of the site. And that highlighted 4 samples of malware on the store! Much to the surprise of the client, who had zero clue of the site being infected....

Adobe Commerce - Improved Magento Vars Store Code Configuration

The default magento-vars.php file that is referenced through the Adobe Commerce documentation leaves a lot to be desired and can become a pain when managing stores with many websites and store views. Luckily we can simplify this configuration using the match implementation within PHP8. This version of the script allows us to configure new store fronts by adding a single case to the match statement. <?php $host = $_SERVER['HTTP_HOST'] ?? ''; $ephemeralHostScope = fn(string $host): ?...
