Tesco to be investigated over privacy concerns
Those exciting folks at The Information Commissioner's Office are going to investigate Tesco over the way they protect the privacy of their customers online.
The ICO probe comes on the back of claims from security experts who have a number of issues with the retail behemoth's website. Apparently, Tesco aren't storing your passwords properly, according to the magnificently monikered Troy Hunt. He revealed that he'd got an email from Tesco that contained his password in plain text, which means that they're probably not storing your passwords cryptographically.
There's also concerns that Tesco aren't using HTTPS (Hypertext Transfer Protocol Secure) which makes customers more vulnerable to phishing attacks and data theft.
Troy said: "HTTP is stateless so the only (practical) way a state, such as being logged in, can be persisted is by passing cookies backwards and forwards between the browser and the website. Because they’re being sent over a HTTP connection, anyone who can watch the traffic can see [those] cookies. And copy them. And hijack your session."
Tesco are adamant that their security is "robust" and claims that they're never complacent ABOUT ANYTHING EVER. We'll just have to see how this unfurls. In the meantime, it might be worth changing your Tesco password to something you only use with them.
