LogJam encryption flaw fix will block some websites
Web-browser makers are preparing a fix for a flaw in an encryption algorithm that makes it possible to spy on supposedly secure communications.
However, the updates will mean a minority of websites will be blocked by the new software.
The “LogJam attack” was discovered by researchers at Microsoft and a number of US and French universities. They believe about 8% of the top one million HTTPS security-protected sites are made vulnerable by the flaw.
