Carna botnet
The Carna botnet was a botnet of 420,000 devices created by an anonymous hacker to measure the extent of the Internet in what the creator called the “Internet Census of 2012”.
Data collection
[edit]The data was collected by infiltrating Internet devices, especially routers, that used a default password or no password at all.[1][2] It was named after Carna, "the Roman goddess for the protection of inner organs and health".[3]
Collected data was compiled into a GIF portrait to display Internet use around the world over the course of 24 hours. The data gathered included only the IPv4 address space and not the IPv6 address space.[4][5]
The Carna Botnet creator believes that with a growing number of IPv6 hosts on the Internet, 2012 may have been the last time a census like this was possible.[3]
Results
[edit]Of the 4.3 billion possible IPv4 addresses, Carna Botnet found a total of 1.3 billion addresses in use, including 141 million that were behind a firewall and 729 million that returned reverse domain name system records. The remaining 2.3 billion IPv4 addresses are probably not used.[6]
An earlier first Internet census by the USDHS LANDER-study had counted 187 million visible Internet hosts in 2006.[7][8]
Further implications
[edit]The data provided by the Carna botnet was used by security researcher Morgan Marquis-Boire to determine in how many countries FinFisher spyware was being used. The use of such legally-gray data to conduct open source analysis raised questions for some, but Marquis-Boire expressed a belief that data is data. "I consider this more like rogue academia rather than criminal activity," he told Wired Magazine.[9]
Number of hosts by top level domain
[edit]Amongst other, Carna Botnet counted the number of hosts with reverse DNS names observed from May to October 2012. The top 20 Top Level Domains were:
| Number of hosts[10] | Top Level Domain |
|---|---|
| 374,670,873 | .net |
| 199,029,228 | .com |
