http://www.visualcapitalist.com/comparing-bitcoin-ethereum-cryptos/ Unless you’ve been hiding under a rock, you’re probably aware that we’re in the middle of a cryptocurrency explosion. In one year, the value of all currencies increased a staggering 1,466% – and newer coins like Ethereum have even joined Bitcoin in gaining some mainstream acceptance. A major problem still exists for the layman: it’s →
https://hackaday.com/2017/09/14/bluetooth-vulnerability-affects-all-major-os/ Turn off your Bluetooth! I checked that mine was turned off after reading this: Security researchers from Armis Labs recently published a whitepaper unveiling eight critical 0-day Bluetooth-related vulnerabilities, affecting Linux, Windows, Android and iOS operating systems. These vulnerabilities alone or combined can lead to privileged code execution on a target device. The only requirement is: →
As the popularity of IoT devices grow, it’s only natural that security holes in some of the systems will become apparent. IoT Devices May Be Susceptible to Replay Attacks with a Raspberry Pi and RTL-SDR Dongle andAttack Some Wireless Devices With A Raspberry Pi And An RTL-SDR articles tell that an easy way to make a →

https://blog.filippo.io/playing-with-kernel-tls-in-linux-4-13-and-go/ Linux 4.13 introduces support for nothing less than… TLS! The 1600 LoC patch allows userspace to pass the kernel the encryption keys for an established connection, making encryption happen transparently inside the kernel. The only ciphersuite supported is AES-128-GCM as per RFC 5288. The kernel only handles the record layer, that is, it only takes care →
I visited today IoT Security Workshop at Aalto University (at Espoo Finland). Here are some slides from seminar →
http://www.osa.org/en-us/about_osa/newsroom/news_releases/2017/high-dimensional_quantum_encryption_performed_in_r/ For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement →
http://www.techrepublic.com/article/how-to-prevent-root-login-on-your-linux-servers/ If you’re overly paranoid about security (which you should be), you might want to consider blocking root logins on your Linux servers. Here’s how to do it. →

The problem, he says, is the belief that privacy and security are mutually exclusive. →
