  • Are you saying it is not secure to use internet at all? Never fill out forms with ssn or other sensitive personal info? The only solution presented here is to use BlueCoat's SSL Visibility Appliance. And it is not a consumer solution.

Heartbleed was discovered by Neel Mehta, an engineer at Google Security, and a team of security engineers (Riku, Antti and Matti) at Finnish security firm, Codenomicon. !!! VIEW THE INFOGRAPHIC
  7. A computer that is on a secure connection to a server will send out a request to confirm that the connection is still active. The server takes that request and stores the data. Then it returns that same packet of data. This secure connection (SSL/TSL), is called a “heartbeat.” It includes two things: a payload, and padding. HOW IT WORKS
  8. VIEW THE INFOGRAPHIC THIS IS WHERE THE BLEEDING HAPPENS Servers using the protocol do not check to confirm that the packet of data actually matches the size indicated.
  9. So, for example, if a heartbeat was sent with a single byte of data, and claimed to have 30 bytes of data. Rather than confirm that the data was only 1 byte, the server would grab not only that, but the next 29 bytes from memory as well and send it back the user. VIEW THE INFOGRAPHIC 1 byte (30 bytes) (30 bytes)
  10. VIEW THE INFOGRAPHIC Imagine what could be in those extra 29 bytes? No data is safe! Passwords Addresses Full Names Credit Card NumbersEncryption Keys *** Social Security Numbers
  11. VIEW THE INFOGRAPHIC Not only that, A malicious user could make as many heartbeat requests as they’d like. With NO TRACE being left behind.
  12. Including heavily trafficked websites such as: Facebook, Google, YouTube and Wikipedia. VIEW THE INFOGRAPHIC are using the vulnerable heartbeat extension. About 500,000 sites
