Snapchat bug lets hackers aim DENIAL of SERVICE attacks at YOUR MOBE
Found on The Register on Monday, 10 February 2014

A security consultant who works for Telefonica has turned up a bug in how Snapchat handles authentication tokens, which enables a denial-of-service attack against users' phones.
Sánchez claims that rather than fixing the problem or contacting him, Snapchat has blocked the accounts he used to test the vulnerability.
Not too long ago, Snapchat decided to ignore a security researcher who told them that it's possible to identify users. The bug went public and quickly a database with users was built. Everybody with a brain worth more than 10 cents would say that Snapchat should have learned a valueable lesson from that. Obviously they did not. So let's just wait a little until this new bug gets exploited too.
