Requirements: Safari 5.0+
We're happy to release our first extension for Safari to protect users: Zscaler Safe Shopping. You can download it from thee Download Safari Add-On.
This behavior is fine for most websites where you just surf and do not leave any sensitive information. But would you be fine with leaving your personal mailing address, your phone number and your credit card number on a website that is fully controlled by ill-intentioned hackers? How do you know the site you are visiting has not been compromised when your blacklist ignores this type of threat?
The Zscaler Safe Shopping plugin is continually fed information regarding compromised and fake online stores. It warns you when you visit one of these domains. The list of domains is checked and updated regularly via Zscaler's cloud security service.
A compromised store is a website where one or several groups of hackers has full access to the website. They can add, remove, and modify pages, access the database, etc. This means they could change an order form to get all your shopper information, or get it directly from the store database, or change the payment form to redirect to a a phishing site, and more.
We detect these compromised online stores based on several factors that show total control by an outside party. Some of these include:
- The presence of a backdoor that allows anyone to control the site, as shown in the "Hot Video" pages: analysis of an hijacked site (Part III) blog
- Spam SEO pages
For regular users, these sites may not show any sign of being hijacked... And that's exactly what the attackers want.
To see a sample warning for a compromised store, go to http://compromised.example.com/ after you install the plugin.
To prevent people from using our list to find compromised stores for malicious purposes, we store the domains a hash table, rather than in a plain text list.
Recently, we've highlighted the number of high profile, legitimate sites, that have been hijacked to lead to fake online stores. These stores often offer up software downloads at highly discounted prices. The downloads are not blocked as malware by Google Safe Browsing, or phishing sites by Phishtank.
We've found about 100 such fake stores that are still up, and more are showing up every day.
To see the warning for a fake store, go to http://fake.example.com/ after you install the plugin.
