A vulnerability from last century, dubbed ROBOT (Return Of Bleichenbacher’s Oracle Threat) is back and potentially impacts a number of major websites including Facebook and Paypal. ROBOT affects the handling of RSA encryption keys as they are applied to the TLS protocol. If a website uses these keys, it is possible to launch a man-in-the-middle attack by sending dodgy queries to a website which result in the session key being revealed. This allows an attacker to decrypt traffic between the web server and the browser.

Samsung's original VR9000 POWERBot was a surprisingly effective robot vacuum cleaner. The new VR9200 improves on the tried and tested formula by adding a remote control and Wi-Fi connectivity, and while it's not hugely different to the existing model, it's a little more versatile in how it can be set up and operated. If you have a small living space, and if vacuuming seems like a chore, then the POWERbot can genuinely help out with your daily cleaning duties.
