Wireless attacks on aircraft instrument landing systems

The Morning Paper

Wireless attacks on aircraft instrument landing systems Sathaye et al., no longer hold: Security was never considered by design as historically the ability to transmit and receive wireless signals required considerable resources and knowledge. In fact, today the majority of wireless systems employed in modern aviation have been shown to be vulnerable to some form of cyber-physical attacks. USENIX Security Symposium 2019.

Record IP Camera Surveillance Video With A Raspberry Pi

The Polyglot Developer

As some of you may know, I have wireless surveillance cameras around my home. Many years back I even released an Android application called SpyFi to be able to view the video feed from these cameras. Up until recently I would have these cameras upload a sequence of images to a remote FTP server every time there was motion. The problem with this is that these were only a sequence of still-images rather than video, and the server was not free or necessarily cheap.

The Paradox of Connection

Edge Perspectives

Wireless technology has made it possible for us to connect to this digital infrastructure (and to each other) regardless of where we are in the world with much less expense and effort. We are becoming more connected with each other and less connected with each other at the same time. The Big Shift that we're experiencing on a global scale is full of paradox – this is just one of many, but a particularly important paradox to acknowledge and address.
