Two months ago, security experts and web users panicked when a Google engineer discovered a major bug — known as Heartbleed — that put over a million web servers at risk. The bug doesn’t make the news much anymore, but that doesn’t mean the problem’s solved. Security researcher Robert David Graham has found that at least 309,197 servers are still vulnerable to the exploit. Immediately after the announcement, Graham found some 600,000 servers were exposed by Heartbleed. One month after the bug was announced, that number dropped down to 318,239. In the past month, however, only 9,042 of those servers have been patched to block Heartbleed. That’s cause for concern, because it means that smaller sites aren’t making the effort to implement a fix.
