Microsoft has issued a security warning about a bug that could let attackers spy on supposedly secure communications.
Called “Freak”, the bug was found in software used to encrypt data passing between web servers and web users.
Initially the flaw was thought only to affect some users of Android and Blackberry phones and Apple’s Safari web browser.
Microsoft’s warning suggests millions more may be at risk of losing data.
The monitoring group has also produced an online tool that lets people check if they are using a browser that is vulnerable to the flaw.
Apple is expected to produce a patch for the flaw next week and Google has updated its version of Chrome for the Mac to remove its susceptibility to Freak. It has yet to say what action it is taking with Android.
