The malware (named after a typo in the code) appeared in October on several e-commerce sites, including the hair treatment company Bosley and the Chicago Architecture Center (CAC). While investigating the attacker's domain (jquerycloud[.]com) a bit further and other potential victims from this campaign were uncovered some months ago. This includes Doves Farm UK, The Fruit Company, Customer Earth Promos, and - due to the file names - potentially iCanvas or TFC: Active compromise of dovesfarm.co.uk: Skimmer 1: Identifier - sClass="yeikyd" - 'dovesfarm.js' (available here ) Skimmer 2: Identifier - sClass="frydbt" - 'icanvas.js' (available here ) Skimmer 3: Identifier - sClass="bfiyad" - 'tfc.js' (available here ) Skimmer 1 - Listener: Skimmer 2 and 3 - Listener: Skimmed Data: RC4 encryption: Data collected: Credit Card Number, Card Holder Name, CVV, expiry day, mont...
