GuruIncSite Malware

A new type of malware called GuruIncSite Malware which is actually a javascript injection has affected thousands of Magento based stores. The malware exploits a vulnerability in Magento or a 3rd party extension to inject a piece of javascript malware into the Magento database, which then infects any visitor to the site. The bad news is that Google has identified these domains and has categorized these online stores as blacklisted affected by the hack.

As per the Sucuri Security blog , this malware is injected in the design/footer/absolute_footer entry of the core_config_data table, but we suggest scanning the whole database for code like “function LCWEHH(XHFER1){XHFER1=XHFER1” or the “guruincsite” domain name. The attack involves the injection of malicious scripts through iframes from the domain guruincsite.com. Both an obfuscated and non-obfuscated version of the infection has been reported.

How to remove GuruIncSite Malware

  • Since this malware is mostly attaching the footer, go to the admin and Navigate to System > Configuration > Design > Footer > Miscellaneous HTML and remove the malicious code there. The hack can be identified by the presence of the code function LCWEHH(XHFER1)[…].
