We're happy to release yet another free Firefox plugin to protect consumers online.
Introducing Zscaler Safe Shopping
This product has been submitted to the official Mozilla Add-ons sites, but will likely take a few weeks to be approved. In the meantime, you can download it from our site.

Why do you need Zscaler Safe Shopping?
While this is fine for most websites, assuming you simply surf and do not input any sensitive information anywhere, but would you be okay with giving your personal mailing address, phone numbers and credit card information to a website that is fully controlled by ill-intentioned hackers? The problem is, how do you know whether the sites you are visiting have not been compromised or not when your tools ignore these types of threat?
Zscaler Safe Shopping is continually up-to-date, via the Zscaler cloud security service, on compromised and fake online stores. It warns users when they visit one of the suspect domains.
A compromised store is an e-commerce website where one or several groups of hackers has full access and can add/remove/modify pages, access the database, etc. This means they can change an order form to get all shopper information, or get data directly from the store's database; they can even change a payment form and redirect you to a a phishing site.
Zscaler detects compromised online stores based on several factors that demonstrate total control by an outside party by becoming aware of:
- The presence of a backdoor that may allow anyone to control the site, as shown in the "Hot Video" pages: analysis of an hijacked site (Part III) blog;
- Spam SEO pages;
- and more.
To see a sample warning of a compromised store, go to http://compromised.example.com/ after you install the plugin.
|Zscaler Safe Shopping Warning - Compromised store|
To prevent people from using our list to find compromised sites for malicious purposes, we store the domains as a hash table, rather than as plain text list.
Recently, we highlighted the number of high profile, legitimate sites, that have been hijacked to lead to fake online stores. These stores offer up software downloads at highly discounted prices. The downloads are not blocked as malware by Google Safe Browsing, or as phishing sites by Phishtank.
We've found approximately 100 such fake stores. Those numbers are still high, with more are coming every day.

Zscaler Safe Shopping Options
You can customize Zscaler Safe Shopping via the following options:
- Whitelist: do not show a warning for a list of user supplied domains
- Blacklist download interval: how often should the plugin download the new list of compromised and fake stores
|Zscaler Safe Shopping Preferences|
In addition to the option menu, Zscaler Safe Shopping adds an icon to the status bar, at the bottom of the browser. This allows you to turn the plugin on and off with a click of the mouse, without having to restart Firefox. The icon becomes gray when the plugin is disabled.
