Bloomberg is out with a report likely to anger all those who have changed their passwords, or plan to, because of the massive Internet security breach called Heartbleed. The story says the NSA discovered the flaw almost as soon as it was introduced in the open-source protocol OpenSSL two years ago, but chose to exploit it rather than fix it. The agency made use of the glitch, and left it in place, to gather passwords and other data. What's more, the story says the NSA "has a trove of thousands of such vulnerabilities" in its arsenal. An outside expert quoted says the decision not to fix Heartbleed "flies in the face of the agency’s comments that defense comes first," and he predicts that the NSA will be "shredded" by those in the computer security field over the revelation.
