Zmap - Single Packet Network Scanner Designed For Internet-wide Network Surveys

Zmap - A Fast Single Packet Network Scanner Designed For Internet-wide Network Surveys #Designed #ethernet #fast

ZMap is a fast single packet network scanner designed for Internet-wide network surveys. On a typical desktop computer with a gigabit Ethernet connection, ZMap is capable scanning the entire public IPv4 address space in under 45 minutes. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in under 5 minutes. ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap currently has…

Scan the Entire Internet in less than an Hour with ZMAP

Zmap is an open source application that can scan the entire internet in about 45-50 minutes just from a single machine. It scans each individual IP on the internet and is much faster compared to the Nmap which does the same task in several months. Zmap, developed by a group of researchers at the University of Michigan—Zakir Durumeric, Eric Wustrow and Alex Halderman, aims at  bringing to limelight the various vulnerabilities of internet data with a view to fashioning appropriate defense measures. Nmap works by sending out signals to individual IP addresses and then awaits a reply from them and then begins to collate these results and data. This process takes quite a long time! However, Zmap sends out encoded requests on all outgoing information and decodes these requests when they are returned. Moreover it does not keep any requests that are outstanding which makes it even much faster, more than 1000 times, compared to Nmap. With Zmap researchers can accurately decipher a given data even when computers are off-line. While running Zmap on a single machine, it can potentially scan the entire IPv4 address space at a great speed of 1.4million packets per second which is over 97% of the maximum speed of gigabyte Ethernet. It does not require any kernel module or any form of specialized hardware. Moreover, the modular architecture of Zmap supports single packet probe which includes UDP scans, ICMP echo request scans, and TCP SYN scans. Read the full article

¿CÓMO ESCANEAR TODO INTERNET 3.7 MIL MILLONES DE IP’S EN POCOS MINUTOS?

¿CÓMO ESCANEAR TODO INTERNET 3.7 MIL MILLONES DE IP’S EN POCOS MINUTOS?

Profesionales de hacking ético y servicios de auditoría de seguridad informática normalmente usan escáner para revisar la seguridad. Escaneo de todas las direcciones IP en Internet no es un trabajo fácil, y si usted no tiene los recursos de un botnet, un simple escaneo puede tomar meses. Va a ser muy difícil, si usted quiere tomar una grande foto de internet porque hacer un escaneo de las redes…

Amun On Ebola Zombies

Just waiting to see if it gets demistified as another Internet hoax. If it doesn't, my only assumption shall be that it was covered up and it was a government experiment mistakenly gone public. Africa is the perfect testing ground for biological warfare testing. Zmap is a vaccine for the future masses. Africa will become desperate enough to consume whatever cure gets conjured up in the dungeon lab of neo colonialism through capitalist M.O. Africa needs saving, just not from Ebola.

Zmap scanning for Minecraft servers

The other week I found a tool called Zmap. Zmap is a tool that allows you to port scan the entire internet in a short amount of time. With a 1gbps uplink you can scan the whole internet in 45 minutes.

Disclaimer - This kind of scan is frowned upon. There are quite a few people who don't seem to like having all of their computers on their network scanned in seconds.

Testing out the tool, I found that scanning the whole internet, 0.0.0.0/0, at my home would take about 30 hours to complete. This is without any other computer on my network using the internet at all.

Onto another host! I decided to move over to another host to start the scan. With them I was able to scan the entire internet in about 3 hours. In that time I got 5 abuse complaints and then banned from that host.

Whoops.

The port I was scanning was port 25565, the default Minecraft port. I managed to get the list off of the server. The list can be found here. The list contains about one million IPs of computers with the port 25565 open.

Of course most of those IPs weren't actually Minecraft servers, or they just had the port open. After running a quick python script that I made, I made a new list with the motd, max players, current player, and IPs of all of the minecraft servers in that list. The list can be found here.

It's worth saying that this list isn't every Minecraft server. It's a lot of them though.

Getting started with zmap in Kali Linux 

At the time of posting, the only other zmap video on youtube was actually a clip of someone using zenmap /facepalm. With that I decided to whip out a quick video demonstrating everything you need to get started using zmap in Kali. Scan responsibly.
