Heartbleed: the bug that put the internet on high alert

In the spring of 2014, the internet was rocked by what security researchers are calling a "catastrophically bad" bug. Known by the dramatic name Heartbleed, the bug left the widely-used, open source OpenSSL protocol vulnerable to attacks that could put servers' private encryption keys into the hands of hackers. Major sites like Yahoo, Imgur, Flickr, LastPass, and countless others were left...

Hacker successfully uses Heartbleed to retrieve private security keys

This morning, content distribution network Cloudflare gave some hope to those affected by the Heartbleed security flaw with an announcement that the bug might not be as bad as feared. In two weeks of testing, Cloudflare said, its researchers failed to exploit the bug to steal a website's private SSL keys, which secures the data sent to users. It issued a challenge to white-hat hackers to successfully retrieve the private security keys — and unfortunately for the web, one of them succeeded.

How do you fix two-thirds of the web in secret?

When word of the Heartbleed bug first came out, news spread like a fire alarm — but it didn’t spread evenly. The vulnerability was spread across as many as two out of every three servers, which made a standard disclosure impossible. Some companies like Facebook got the news early, either from Google or OpenSSL itself, and were already patched when Monday’s news broke. Others, like Amazon and Yahoo, were left scrambling to protect...

'Trivial' mistake that caused Heartbleed crisis highlights fragility of the web

The "Heartbleed" flaw that has turned internet security upside down was added to the open-source OpenSSL protocol on New Year's Eve 2011, experts now believe. It was entered by one man — German software developer Robin Seggelmann — and a subsequent review failed to pick up on the catastrophic coding error Seggelmann had made.
