The credit card web skimmer, Caesar Cipher Skimmer, is targeting CMS platforms like WordPress, Magento, and OpenCart. It operates by injecting obfuscated malware into e-commerce sites to steal financial information. The skimmer uses various methods to conceal its activities and can adapt its responses based on the website it infects. Site owners are urged to prioritize security measures and monitor for suspicious activity.
From the meeting notes, we gathered several key points:
1. A new credit card web skimmer called Caesar Cipher Skimmer is targeting multiple content management system (CMS) platforms like WordPress, Magento, and OpenCart with the goal of stealing financial and payment information.
2. The latest campaign involves making malicious modifications to the checkout PHP page associated with the WooCommerce plugin for WordPress to steal credit card details.
3. The skimmer uses a substitution mechanism employed in Caesar cipher to encode the malicious code into a garbled string and conceal the external domain that’s used to host the payload.
4. The attackers have been spotted misusing the legitimate WPCode plugin to inject the skimmer into the website database and performing JavaScript injections on database tables such as core_config_data on websites that use Magento.
5. Due to its prevalent use as a foundation for websites, WordPress and the larger plugin ecosystem have become a lucrative target for malicious actors, allowing them easy access to a vast attack surface.
6. It is recommended that site owners keep their CMS software and plugins up-to-date, enforce password hygiene, and periodically audit them for the presence of suspicious administrator accounts to mitigate the risk of such attacks.
