Magecart building momentum since 2000s
Magecart attacks are becoming well known in the cyber security community, as its responsible for some high-profile breaches like Ticketmaster and Newegg and is a growing concern for online retailers or any business harnessing consumer credit card data online. If successful, a Magecart attack can be extremely damaging to the consumer whose details have been stolen and severely damaging to the reputation of the organization who suffered the breach.
“Magecart is a prominent criminal syndicate and focuses on skimming customer data from web forms to gain credit card numbers and personally identifiable information (PII).”
Magecart is a criminal specialism we are seeing more and more of targeting ecommerce websites. Where specialist developers will create ‘kits’ built with the intention of stealing credit card data from online stores but often take no part in the criminal act itself. The ‘kit’ creators earn money either by selling their ‘kits' or by entering into profit-sharing agreements with groups who eventually go on to commit the attack and share the commission between them. Companies affected by Magecart include:
- Australia Bushfire Donation site
- US retailer Hanna Andersson
- Education management Blue Bear software
- Macy's online store
- First Aid Beauty
- British Airways
- Leisurewear retailer Sweaty Betty
The criminals earn money based on the value of the organization’s data being targeted and is set by those running the illicit stores. However, criminals aren’t biased and will be attracted to any website harnessing credit card data as they look to exploit outdated software vulnerabilities and it isn’t just an issue fit for the biggest online retailers. Criminals aren’t fussy as they look for the easiest means to maximize their criminal intent and shouldn’t be ignored. Routinely we see criminals gain access to various compromised websites via e-commerce content management systems (CMS), proving how important it is for all online ecommerce businesses to secure all their web apps to ensure the door remains firmly shut to these attacks.

Keep Magecart at bay and stay in control of your application security
For organizations who self-host their e-commerce stores, you need to continuously monitor and test security of your application for vulnerabilities including regular and automated pen testing. If you rely on a third party to host your online store, there is a degree of risk acceptance and you must entrust that third party to maintain the same security practices you expect. Cross-site inclusion of content is extremely common practice and poses a big risk as most sites have heavy dependencies, and often malicious code can sit on the owner’s site without them knowing. Once a website is infected, the payment card information is harvested without the organization being aware that they’ve been compromised.
Cloud hosted online stores are no more or less at risk than any other online websites. Almost all the risks related to Magecart come from outdated ecommerce stores using a standard solution, custom web app vulnerabilities, or breaches hitting a central provider’s hosting scripts and used by multiple other businesses.
How to prevent risk of Magecart attack
If you have an application security solution in place this will eliminate the risk of Magecart attack through:
