The privacy scares and increase in hacking attacks over the last few years have significantly improved HTTPS adoption. Between the need to show users that the application is secure and the need to comply with standards such as PCI-DSS, HTTPS adoption has pretty much broken the roof. In addition, Google's move to list sites using HTTPS higher on search results and the availability of easy to use tools to enable HTTPS has also helped.
Troy Hunt, a well-known security expert, published a blog post where he called out two online retailers for leaking sensitive user data. One of the retailers had enabled a special “feature” on their website. If an email address was submitted at checkout, while not logged in, the website still presented all the shipping details related to that account. Theoretically, this meant that anyone could submit any email address, and if it existed on the website, all the shipping information (including mobile numbers) would be displayed!
When contacted regarding this issue, the e-retailer responded –
The privacy implications of this “feature” are quite scary. It leaks user’s data very simply, without any “hacking”. Setting that aside, the misconception that turning on HTTPS alone protects the site and its users is even scarier. HTTPS only secures against eavesdropping by encrypting the traffic. It cannot protect against misconfigurations of this type. The feature may make the site easier to use, but that should have been balanced against the privacy implications and authentication should have been enabled.
User privacy implications aside, the website should have also looked at other business-impacting possibilities. A competitor could have automatically run a list of email addresses against the site, scraped all the user data, and used it for an advertising campaign. Further, the site could have broken privacy laws in their jurisdiction, leaving them open to legal action.
HTTPS adoption is a requirement for all websites and applications on the Internet today. In a time where the conversation on user privacy and data theft is front and center, it allows websites to provide easy security against many attacks and secures their users with ease. However, it is not a panacea for all types of attacks. Web application owners and users should educate themselves on the basics of web security and ensure that they are protected always.
