Samsung Windows Laptop Owners Urged To Download Fix To MitM Vulnerability | Threatpost | The first stop for security news. Man In The Middle attack is a name given to particular security hacks that can allow a hacker to gain complete control of a particular machine, and install malware and spyware on the infected computer. The hacker must be on the same WiFi or computer network as the target, so these attacks are most dangerous if you use public WiFi networks, or have a shared network with persons not well known to you. I am going to assume that your family members won't be hacking you on your own network, and that your home or office WiFi network is locked down; but, if you are using Internet cafes or other public networks without an encrypted VPN, you are vulnerable. My own Samsung computer had to be patched to prevent an MITM attack recently, since Samsung was not encrypting traffic between the update software and Samsung's servers. A MITM could intercept the software requests and spoof the replies so that its malware could be installed on the Samsung computer seeking updates. Once installed, the hacker had complete control of the infected computer. So, when your computer manufacturer tells you to patch your system, do it. Be careful out there.
