Raise your hand if you subscribed to one or more of the newly launched Kardashian-Jenner websites. (We know you're out there.) Guilty? Well, you won't be pleased to hear that your contact information may be easily hacked. Yes, you read that correctly. According to TechCrunch, 19-year-old developer Alaxic Smith was poking around the back end of the websites and found an "open, unsecured API." He was able to access the first and last names of over 600,000 people who subscribed to Kylie Jenner's website and could access the same information on the other sisters' sites, as well. He posted about it on his blog, but did not release the data. "Besides being able to access this user data," TechCrunch writes, "Smith says he found he was also able to create and destroy users, photos, and videos." TechCrunch reached out to Whalerock Industries, the company that operates the websites, and received the following statement: "Shortly after launch, we were alerted that there was an open API. It was promptly closed. Our logs indicate that the author of the blog post was able to access only a limited set of names and email addresses." Even so, it's never a good sign that a website gets hacked by a 19-year-old just a few days after launching. In any case, Josh Duggar, you might still want to cancel your Kylie Jenner account — better safe than sorry.
