Abstract While playing around with the Nmap Scripting Engine (NSE) we discovered an amazing number of open embedded devices on the Internet. Many of them are based on Linux and allow login to standard BusyBox with empty or default credentials. We used these devices to build a distributed port scanner to scan all IPv4 addresses. These scans include service probes for the most common ports, ICMP ping, reverse DNS and SYN scans. We analyzed some of the data to get an estimation of the IP address usage. All data gathered during our research is released into the public domain for further study.

2160p is the shorthand name for Quad Full High Definition (QFHD), a video mode planned to appear in future HDTV products.[1] It has a resolution of 3840×2160 (8.3 megapixels in the 16:9 aspect ratio) and is one of the levels of 4K resolution.[2][3][4] The number 2160 stands for 2,160 lines of vertical display resolution, while the letter p stands for progressive scan or non-interlaced. In a progressive image, the lines of resolution of the image go from the top of the screen to the bottom.
