Mirai Botnet Attackers Are Trying To Knock Liberia Offline (zdnet.com)

Zack Whittaker, reporting for ZDNet: One of the largest distributed denial-of-service attacks happened this week and almost nobody noticed. Since the cyberattack on Dyn two weeks ago, the internet has been on edge, fearing another massive attack that would throw millions off the face of the web. The attack was said to be upwards of 1.1 Tbps -- more than double the attack a few weeks earlier on security reporter Brian Krebs' website, which was about 620 Gbps in size, said to be one of the largest at the time. The attack was made possible by the Mirai botnet, an open-source botnet that anyone can use, which harnesses the power of insecure Internet of Things devices. This week, another Mirai botnet, known as Botnet 14, began targeting a small, little-known African country Liberia, sending it almost entirely offline each time. Security researcher Kevin Beaumont, who was one of the first to notice the attacks and wrote about what he found, said that the attack was one of the largest capacity botnets ever seen. One transit provider said the attacks were over 500 Gbps in size. Beaumont said that given the volume of traffic, it "appears to be the owned by the actor which attacked Dyn." An attack of that size is enough to flatten even a large network -- or as was seen this week, a small country. Update: 11/03 19:37 GMT: The title of the story (same as the ZDNet's story) was updated to mention the name of the country. The summary was updated to reflect the same, as well.

      Liberia is hugely important in world history, having adopted a Constitutional Government in 1947, although it was inhabited before then. Who took part in this mass migration? A particular group of humans in the US who were emancipated from being chattels (property) used for uncompensated labor (slavery). . . to being people under US Law. A lot of them wanted to go back at leastto their home continent, and many probably wanted to just get the hell out of the US.

      You could do with some broader perspective too. Not everyone in the World is interested in a 19th century destination for freed US slaves, even if it interests some Americans as such. In the UK here I doubt that one person in 20 could point to it on a map or even know that it is in Africa. It did have a claim to fame once as having the largest fleet of merchant ships in the world (as a flag of convenience). Land area has nothing to do with it.

      Oh, before you accuse me of narrow-mindedness, I am a bit exceptional in that I once had a Liberian GF, who claimed descent from those slaves, and said there was a lot of tension today between such descendants (who tend to form the upper classes) and the "natives" of Liberia because obviously the slaves did not neccesarily originate from Liberia. The ex-slaves were imposed on the natives by the USA in a fit of idealism; in fact it was a USA colony although that can only be whispered as the USA is supposed to be against colonialism. The capital Monrovia was named after the US president Monroe, and the flag is obviously inspired by the Stars and Stripes.

    In my opinion, this demonstrates some simple things.

    If the IoT creators cannot be bothered to properly secure their devices out of the gate, then they need to give some nonvolatile storage of some kind that can hold the files in /etc, and perhaps /home.

    It does not need to be big. 2mb would be spacious.

    Just enough that the init system can be tailored, the root password can be changed, and the cryptokeys can be regenerated and retained.

    That way somebody can honest to god actually secure their device after purchase. You know, disable that open Telnet daemon, change the default root password, and use some hard to crack 4096bit keys for SSH that aren't all over the damn net.

    They could do this the way eg, OpenWRT does it, with a pivot root. It could be reset to the "Factory insecure state" by holding in the reset button that way, preventing users from breaking it on a misconfiguration. If it would cost too much to make the devices properly secure out of the box, then at least give them enough real internal storage that mounts properly on boot, that people that DO know what they are doing can fix their fuckups after purchase, and have it stick.

    1. Re:Demonstrates some simple things by wierd_w · · Score: 3, Insightful

      Here is how you do it:

      1) The device ships in "Insecure, please rape the shit out of me!" mode, with open Telnet, and a default root password.

      2) The software that comes with the IoT device looks for this insecured bundle of filth. It then generates a random 32byte password, stores it in its local config file for the device, sets it on the device, and tells the device to generate a new crypto key pair. It then connects over the secure connection, and remotely disables the telnet port. It does all this while the user looks at pretty pictures or something.

      3) Once the device is in "Secure mode", it no longer listens on any port for telnet traffic, and does everything over SSH with the generated keys, and the random password.

      All the user has to do is "insert the damn CD into the tray and set up the device, idiot." and off they go with a secured device.

      For those of us with the inclination, we can start with the unsecured mode, manually log in via telnet, and set it up the way WE want.

    It's easy enough to do in your head - 1.1Tbps is less than half 620.Gbps. It would have had to be more than 1.24 Tbps, more than 10% larger than the claimed "upwards of 1.1Tbps", and there's no indication in the original story that it ever got anywhere near that high. Aside from satellite connections, the single fibre connection s the only way in or out. That is confirmed by the article stating that the attack was directed against one of the two companies cooperatively operating the fibre.

    One transit provider said the attacks were over 500Gbps in size.

    So from the story, it's an attack on one company, and Level 3 reported far less. In an email, Dale Drew, chief security officer at Level 3 Communications, confirmed it had "witnessed an attack against a telecommunications company in Liberia" from the Mirai botnet.

    Far less than 1.24 Tbps, and no facts cited to even make it more than 620 Gbps. There is no actual data in the article to justify the claimed size, irrespective of the bad math.
