Botnet Security The Internet

Mirai Botnet Attackers Are Trying To Knock Liberia Offline (zdnet.com) 73

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.

        I realize this is /., but I thought most people read the title and then started making accusations.

        It's also in TFS, though not in the first sentence.

        Which is better than the actual source. They don't have the country in the title, and you have to scroll past a picture and the first paragraph to see which country it is. It's also first mentioned in a picture of a Twitter post before it's actually in the article. Believe it or not, the /. posting is better than the actual source with reg

      It's not just the post: the linked article fails to name the country until the 7th paragraph.

      -- Liberia has more land area than Portugal or Hungary or Austria.

      Seems like the author of the article could use a broader perspective.

        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.

      And the article calls Liberia a "little-known country"?!? WTF?

      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

      • 1847, NOT 1947.

        Yes, that was roughly 20 years before the US Constitutional Amendment banning chattel slavery, but there were indeed some "free men" at the time. It's the source of the surname "Freeman".

The power that this botnet has is unprecedented, this is a digital Godzilla (DigiZilla?) running rampant on the streets of LIberia with the only defense some antiquated machine guns.

  • What devices are in the Mirai botnet?

  • 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.

      Sure, I bet my grandpa, who just wants a DVR to record his outdoor cameras, will be able to accomplish what you just outlined. I mean, I certainly understand that what you are describing needs to be accomplished, it is has just been proven (time and time again) that the end user isn't going to do it.

      From my armchair perspective of what's going on, these devices aren't getting exploited by some hard-to-find backdoor, they are getting exploited by having the same damn password on every device that ships. THAT

        Easy to fix. Always unique keys, always unique root passwords. Cheap and easy to implement.

Is not your problem, it's grampa problem, or marketing problem, or PHB problem, never a problem with the people that actually copy pasted the Linux on those things.

            • I don't know, by default no updated install of windows or OS X can be telnetted/ftped from the outside with any sort of "default" password. Comparison is tricky because you can't really compare a kernel+webstack+controllers with a full blown desktop OS, you are right but it does not negate my point, programmers have to apply the most basic security checks, and any company that fails to employ proper professional should be taken out of business.

        Maybe. Liberia is small potatoes, though. The bigger the ultimate target, the bigger the street cred. I seriously doubt, however, that anybody would take down an entire country of any size just for bragging rights.

    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 coo
