Trading in stock of medical device paused after hackers team with short seller

Trading in the stock of medical device manufacturer St. Jude Medical was halted Friday afternoon after a dramatic drop in its value. That drop was triggered by news of alleged vulnerabilities in the company's cardiac care devices. The vulnerability was disclosed not in a report by the company company, but by security researchers partnered with Muddy Waters Capital, an investment firm that had "shorted" St. Jude's stock on the information in order to profit from a drop in the stock's value.

The researchers at the security firm MedSec chose to take this route to disclosure, MedSec CEO Justine Bone said, to "ensure that St. Jude Medical responds appropriately and with urgency." The partnership with a short seller short-seller is a fundamental departure from the established approach of responsible disclosure normally taken by researchers. But it also represents an approach that bypasses the sort of legal maneuverings and threats, suppression of information, and inaction that have been experienced by researchers who have discovered vulnerabilities in other products. Researchers who discovered a vulnerability in Volkswagen electronic engine locks, for example, were forced to withhold a paper for two years through a court injunction filed by the automaker in 2012.

Muddy Waters issued a report on Thursday claiming that it had demonstrated "two types of cyber attacks against STJ implantable cardiac devices: a 'crash' that causes cardiac devices to malfunction... and a battery drain attack that could be particularly harmful to device dependent users." The report claimed that the vulnerabilities had been proven in "multiple demonstrations evidencing how hollow STJ's device security is."

I took the complete C&H out of the library a few weeks ago and realized A) whenever I'm feeling awful, chaotic overwhelmed, C&H will help; and B) I loved these books as a kid, I loved them as a teen, I loved them in my 20s, I love them in my 30s, and I will probably always love them; and C) I desperately want Bill Watterson to be my friend.

They kind of had to kill the EU if they were going to make any sort of sequel movies. There's just too much there, and not all of it is of good quality so rather than go "Okay, well that's canon, and this, and then this bits, and this series" they're able to start over fresh and take the parts from the EU that really worked and use those. It sucks, yeah, and I'm sure you're going to be just as salty, but there was no way they were going to make the EU into their movies. The books are all still there, you can still buy and enjoy them, just because something isn't canon (and considering that some of the EU was less canon than other bits, I really don't see how that in specific is the problem) doesn't mean you aren't allowed to read and enjoy it.
