Heartbleed, LastPass, and Make Windows Faster

April 17 2014

The Heartbleed exploit explained with jellybeans, tweak Windows 7 or 8 for extra speed, manage your passwords with LastPass, and a first look at the WRT 1900AC.

Heatbleed

What is the Hearbeat?
* The problem lies in the "Hearbeart"
- It's a way to keep a SECURE TLS session alive /// to keep it from "timing out"
- The Heartbeat is a payload of arbitrary data which is sent from one end of the connection to the other, and back again.
- If the heartbeat makes the round trip intact, then both sides of the connection know that the connection is still active and still secure.

What is the Exploit?
* The exploit is in the way that OpenSSL responds to the heartbeat.
- The SENDER of the "keep alive" packet gets to decide how much arbitrary data it sends.
-- The sender sends heartbeat of a certain size, then tells the receiver how much data must be sent back
*** Here's the rub... along with that data, the sender tells the receiver (running OpenSSL) how much data should be sent back... and OpenSSL doesn't check that number with the size of the incoming data.
-- Since the SENDER decides how big the arbitrary heatbeat data will be, and because OpenSSL trusts the sender as to how much data is in that heartbeat, the SENDER can sent a heartbeat that will return data that was NOT originally sent by the sender.
-- In other words, an attacker can make the compromised system send data that was intended to be secure and private.

How is the Exploit Used?
* To use the exploit, an attacker would first establish a SSL connection to a compromised system.
* The attacker would then send a heartbeat to the compromised system with a 1byte payload
* However, the attacker tells the compromised system that it must return 64k Bytes
* The compromised system sends back a 64k heartbeat response, giving the attacker 63,999 bytes of data that is SHOULDN'T have released.
* The attacker keeps doing the attack until they have the compromised systems certificates and any other information that is in memory.

What is the impact
* If the attacker is able to steal the credentials of the compromised system, they are able to do a number of things:
1. A MITM attack on people connecting to the site -- An attack in which EVERYTHING is in the clear
2. The ability to create "spoof sites" with the authentic certificate of the compromised site

Speed Up Windows

"Remote Assistance" is a service that runs in the background of Windows 7 & 8, allows a remote "helper" to log into your computer to fix problems while you watch. Most people will never never use the service, and it can actually be a security hole.

"System Restore" is a background service that keeps track of "save points" - Theoretically it will allow you to return to one of these "healthy" save points should something happen to your OS. It's a useful feature of Windows, but it CAN'T clear viruses and it can only return to save points that is has created... meaning that it almost never gets you back to a completely healthy image.

To Turn Off these Services
1. Right click the "Computer" icon on the desktop and choose "Properties"
2. To the left of you computer's stats, you'll see "Control Panel Home" along with four shielded options. Click "Remote Settings"
3. You'll see a field for "Allow Remote Assistance Connections to this computer"- uncheck that option and click "apply".
4. Click on the "Remote Assistance" tab and look for "Protection Settings" - Select the drive on which protection in enabled and click "Configure"
5. Select the radio button to "Turn off system protection" and apply the change.

LastPass Password Manager

- After the Heartbleed security breech and just everyday use of Multi-site logins, you should be using strong passwords and different passwords for every site.
- Lastpass keeps your passwords in a Vault and helps you generate new random passwords and works on all platforms
- Your passwords are encrypted, which is only stored on your machine. That means even LastPass doesn't know your password. It's called the "Trust No One" approach
- Don't believe me? Watch Leo and Steve Gibson go into detail not only about Heartbleed but Lastpass and Trucypt
