Rewterz Threat Alert – Lazarus JavaScript Skimming Campaign

Severity

High

Analysis Summary

Lazarus JavaScript Skimming Campaignis targeting eCommerce merchants in North Ameriaca. In this campaign, the attackers inject malicious JavaScript code into the websites of merchants and service providers to harvest payment information, such as billing address, account number, expiration date, and CVV2 from the checkout forms on eCommerce pages. These skimming campaigns, especially against service providers impose a greater threat to their businesses. 

The attackers compromised the content delivery network (CDN) implementation for these service providers and modified JavaScript files hosted on the CDN. The malicious code within these modified files was then integrated into the eCommerce environments of merchants using the service provider’s solutions. This enabled the attackers to harvest payment details from any eCommerce website that utilized the code of the compromised provider on their checkout pages, effectively compromising numerous eCommerce merchants with one successful code inject.
