The number of compromised and fake online stores is growing, and unsuspecting users are falling victim to such sites every day. When end users attempt to purchase goods from such sites, they are giving away sensitive information such as credit card numbers. Zscaler Safe Shopping is a free Firefox plugin, which warns users when they visit one of the suspect domains. Zscaler Safe Shopping is continually updated, via the Zscaler cloud security service, whenever new compromised or fake online stores are identified.
Virtually all browsers contain blacklists to prevent users from accessing known malicious sites: Google Safe Browsing, Phishtank, etc. However, these blacklists do not generally block sites that have been compromised. Rather, they block the malicious pages that hijacked sites ultimately redirect to. This behavior is fine for most websites where you just surf and do not leave any sensitive information. However, in the case of shopping and commerce sites, where a user leaves a mailing address, phone number and credit card details, this type of blocking is not sufficient. These types of commerce attacks are successful because users often have no idea that the site they are visiting has been compromised, or is a scam built by ill-intentioned hackers.
"Attackers are constantly adjusting their tactics and traditional security controls are failing to keep up," said Julien Sobrier, senior researcher at Zscaler labs and developer of the new Safe Shopping plugin. "As blacklists have improved their detection of traditional attacks such as fake antivirus campaigns, attackers are now shifting to fake and compromised storefronts, which are not being detected by the browser."
