Chips are down: hit by Magecart hackers

A popular website that poker players utilize to improve their game via statistical data has come under attack. The website in question,, was discovered to be under assault by a Magecart script that seeks to steal payment card data. Malwarebytes researchers were the first to uncover the situation when a user reported suspicious activity to the Malwarebytes forums. Magecart is believed to be responsible for several previous high-profile hacks.

In the exchange, which can be found here, the user smokingjoker reports that his Malwarebytes software blocked domain traffic to The data that smokingjoker provided showed displaying outbound traffic to the IP address which resolved to port 50426. As the staff member AdvancedSetup stated in response, “ajaxclick[.]com is a domain that hosts a credit card skimmer. Skimmers are pieces of code that can steal credit card details from unaware online shoppers. What is unusual in your case is the fact that this is a poker application that attempts to connect to this site, rather than your internet browser. However, this is not a false positive and we will keep blocking this site.”

According to the subsequent blog post on the incident, Malwarebytes states that the skimmer with Magecart code was specifically crafted to target What led researchers to make this conclusion was the fact that “variable names match its input form fields,” and additionally, “the data portion of the skimmer script has the site’s name hardcoded as well.” Malwarebytes researchers state that an outdated sub-domain and root domain are to blame for the skimmer code injection. Specifically, the blog post notes that both domains are using Drupal version 6.3x, which has been verified to be outdated and highly vulnerable to these types of attacks. Researchers also noted their surprise when the Magecart code was found. The main reason is that skimmers, according to researchers, usually target vulnerabilities in Magento for Magecart attacks (rather than Drupal).

It seems that an up-to-date malware blocker will protect you against this skimming attack. Nevertheless, poker players should avoid for now until they update the Drupal version. The last thing you want is for hackers to have pocket aces before the flop while you are sitting with a 4 and 10 offsuit.
