If you’re an 02 UK subscriber you might want to read this. Apparently when on the O2 UK network, and you’re browsing the web, your phone number might be exposed to all visited websites. O2 customer Lewis Peckover discovered that his phone number was included in the HTTP headers sent to each website he visited when connected to 3G over O2.
What are HTTP headers? It’s information exchanged between the browser and the web server before the page is loaded. You’re phone number would be included alongside information like your IP address and OS. On the bright side, the header used to send phone numbers is “x-up-calling-line-id” which isn’t normally logged by web servers, but malicious servers could have access to it easily.
This doesn’t have anything to do with Android in general, but this does affect Android users on the O2 network. I’m pretty sure this isn’t something O2 intended, and they did say they are “investigating” the issue. Hopefully it will be resolved quickly without any damage. For now, you can head over to Lewis Peckover’s site to find out if you’re affected. Just click the source link below and see if you spot your phone number among the HTTP headers. Make sure you’re not connected to WiFi, you must be on the O2 network. We’re told that not everyone is affected, but the majority are.
