Infected computers that are part of a botnet receive their commands through a command-and-control server. These servers are routinely dismantled by security defenders in a process known as sinkholing. A botnet was recently observed using the bitcoin blockchain to update the IP address of a command-and-control server. The attackers would send a tiny amount of cryptocurrency to a bitcoin address, and then the bots would use scripts to decode the transactions into IP addresses. It is simple for security researchers to disrupt this method, and it could be potentially costly for attackers.

A team of scientists launched a box containing four types of bacteria and fungus into the stratosphere to expose them to several hours of Mars-like conditions. The experiment found that some species of fungi could be resistant to the Martian surface if accidentally delivered by spacecraft missions. This finding has implications for human Mars missions, as mission planners will have to figure out a way to prevent organisms in our microbiomes from spreading into the Martian environment.

Flight Simulator uses data from Bing maps to generate its maps in real-time, resulting in some of the most accurate recreations of real-life places. Players can even spot their own houses when they fly over in-game. This article is a guide to building something similar, but in much lower detail and on a much smaller scale using React, Three.js, and WebGL. An interactive working example is available.
