“Suppliers can include vendors that integrate with sites to add or improve site functionality or cloud resources from which websites pull code, such as Amazon S3 Buckets. These third-parties integrate with thousands of websites” states the report.
In June, the gang made the headlines again, after infecting over 17,000 domains by targeting improperly secured Amazon S3 buckets.
Recently, IBM researchers observed one of the MG5 group 5 using malicious code to inject into commercial-grade layer 7 L7 routers.
Following a consolidated pattern of attack that is common in the hacking community, Magecart attempt to exploit vulnerabilities that the victims have yet to patch even is security updates have been released by Magento and other software vendors.
Attackers also look for new attack vectors to distribute their software skimming, such as compromising creative ad script tags to leverage digital ad networks to generate traffic to their skimmers and hit thousands of sites at once.
RiskIQ report revealed that of all malicious advertisements it has analyzed, the 17% is associated with the Magecart groups.
Below other interesting insights included in the report:
- 17% of all Malvertisements detected by
RiskIQcontain Magecart skimmers
- The average length of a Magecart breach is 22 days with many lasting years, or even indefinitely.
- Shopping platforms such as Magento and OpenCart are the lifeblood of many Magecart groups.
RiskIQhas detected 9,688 vulnerable Magento hosts. Magecartinfrastructure is vast, with 573 known C2 domains, and 9,189 hosts observed loading C2 domains.
- Because Magecart skimmers stay on websites for so long, threat actors are purchasing Magecart infrastructure that’s gone offline to assume access to these breached sites.
