A researcher used 420,000 compromised Internet of Things devices to capture some interesting data about the IPv4 addressable Internet space.
In a paper, an unnamed researcher described how a project to NMAP to find unprotected devices online, i.e. the Internet of Things, provided a unique window on the virtual world. By compromising each vulnerable host device, the researcher then enlisting that device to scan for other unprotected hosts. With about 100,000 compromised devices (the "Carna Botnet") the researcher claims to have scanned the entire IPv4 addressable space, many times. The project ran from between March and December, 2012 and collected 9 Terabytes of data.Read More
Attribution in cyberspace is tricky thing. The Chinese are working on a next-generation Internet that they hope will identify the source of packets no matter how obfuscated the path may be as well as provide IP addresses for all its citizens.
A paper from the Philosophical Transactions of the Royal Society details the proposed changes to the backbone of the Internet as we know it, both IPv4 and IPv6. According to New Scientist, "first up is the internet's inability to block malicious traffic as a whole. While malware can rapidly replicate and distribute itself across the net, organisations can only respond to individual instances of online aggression." That would be different under the Chinese system, which would better identify the source and allow for it to be blocked.Read More
The proclaimed “Father of the Internet,” Google VP Vint Cerf, warns that there won’t be enough IP addresses left to accommodate people and businesses connected via the Internet. What does this mean? The Internet is dependent on an internet protocol called IPv4, and when Cerf first began the experiment, he had no idea that the Internet would reach its capacity. IPv4 enables one computer to communicate with another, and until the next version of the protocol is put in place, the way that we unite over the Web will be seriously compromised.
The Sydney Morning Herald reports that,Read More
