The three million toothbrush botnet story isn’t true.

Here’s the original source of the story: https://archive.is/2024.01.30-203406/https://www.luzernerzeitung.ch/wirtschaft/kriminalitaet-die-zahnbuersten-greifen-an-das-sind-die-aktuellen-cybergefahren-und-so-koennen-sie-sich-schuetzen-ld.2569480

It’s simply a made up example. It doesn’t exist. It starts talking about NoName Ddosia, too, which also isn’t toothbrushes.

The toothbrush thing has gone viral despite it being total bollocks.

Now NoName have picked up the fake toothbrush story as propaganda for their members.

Good job, Fortigate.

Fortigate haven’t replied to my PR question about it. Given this is several times the size of the world’s biggest botnet, you’d think they’d have any evidence.. at all.

Kudos to @BleepingComputer for doing actual journalism.

Fortinet also declined to comment to me.

It's a completely made up story, which is now being circulated as Russian propaganda.

The unlikely 3 million electric toothbrush DDoS attack

A widely reported story that 3 million electric toothbrushes were hacked with malware to conduct distributed denial of service (DDoS) attacks is likely a hypothetical scenario instead of an actual attack.

BleepingComputer
Fortigate have issued me a statement. The toothbrush DDoS story is completely made up.
I’d like to thank all the Mastodon reply guys in the thread who decided the story was real, btw, based on vibes.
Probably the best reply on one of the stories so far.
It’s now made it to YouTubers 🤣 who are doing better journalism and threat intel than.. journalists and threat intel. https://youtu.be/sVpe0ZEZ1Ho
Did a Massive Toothbrush DDOS Just Happen?

YouTube

The newspaper that had the first article about the Fortigate toothbrush botnet have updated the story and doubled down:

“The article originally said that the case "really happened like that."
This information came from the company Fortinet, which had described the case as real in the interview and proofread the article before publication. Fortinet is now correcting this statement and calling it a "hypothetical scenario". https://www.luzernerzeitung.ch/wirtschaft/kriminalitaet-die-zahnbuersten-greifen-an-das-sind-die-aktuellen-cybergefahren-und-so-koennen-sie-sich-schuetzen-ld.2569480

Cybergefahren: So schützen Sie sich

Die Zahl der Angriffe erreicht unvorstellbare Höhen, wie neue Daten der Cybersicherheitsfirma Fortinet zeigen. Welche Entwicklungen Sorgen bereiten und warum es trotzdem Anlass zur Zuversicht gibt.

@GossiTheDog While I typically dont like the German/Swiss tradition of authorizing/proofreading quotes in articles (something nobody else does as far as I know), here it clearly paid off.
@GossiTheDog Sounds like Fortinet Switzerland will soon look for someone to replace a position...
iTWire - Malwarebytes shines as bogus toothbrush attack tale swallowed by most

Security firm Malwarebytes has been one of the few companies or individuals that refused to swallow a bogus report about three million smart toothbrushes being used in a DDoS attack. A large number of so-called tech publications simply regurgitated the report which first appeared in the Swiss newspa...

@GossiTheDog

I have been literally biting all my fingers *and* my tongue (for some reason) to stop myself from going into people's posts and replying

IT'S A FAKE STORY YOU MORON. IT'S CLICKBAIT AT BEST

So far I have been strong

#Toothbrush #SmartToothbrushes

@GossiTheDog It seems appropriate that vibes are used for attribution at this point
@GossiTheDog Vibes are the best way to evaluate electric toothbrushes.
@GossiTheDog @BleepingComputer yeesh, declining to comment whilst their stock price spikes is some cynical shit. I'd like to hope this would damage trust in them but I'm not feeling that naive today.

@grimmware @GossiTheDog @BleepingComputer
You might think that Fortinet having had backdoors of their own (e.g. https://rhinosecuritylabs.com/enterprise-security/fortinet-backdoor-found-ssh-netscreen/), as well as critical RCE vulns, might affect the stock price too.

Possibly related: I've got a Fortigate 100D sitting here, unused in ages, if anyone wants to cover shipping etc.

@tim_lavoie @GossiTheDog @BleepingComputer strangely enough you're not really selling the Fortigate ;)
@GossiTheDog @BleepingComputer I’m still trying to figure out what the problem was with toothbrushes that needed fixing with an internet connection.
@GossiTheDog @BleepingComputer I am glad that I was skeptical enough when I saw the story come through yesterday and didn't amplify.... figuring the DDOS dudes would sort it out...indeed they did. I wonder how many posts from yesterday were deleted today? Lol.
@GossiTheDog Aw dang, thanks for sharing this. But the archive.is link doesn't actually let you read the story. It's obscured even in that form by other text.
@mttaggart @GossiTheDog just scroll down past the nag message.

@GossiTheDog OH NO! I thought it was so funny. Oh well.

"Sir, we've been hacked!"

"Who? The Russians? The Chinese? Aliens?"

"Three million toothbrushes."

@GossiTheDog I want to believe!
@GossiTheDog I mean, sure, it's supposedly twice the size of Mirai... but that's not a red flag or anything is it?
--edit--
Did I say twice? Probably about 5 times larger. If true, this would be one of the world's biggest known botnets, but that wasn't the headline?
@GossiTheDog suddenly smart toothbrushes are not a joke anymore (or are they even more hilarious?)

@GossiTheDog oh man I fell for it. Thanks for the fact check.

Interesting though how easily lots of people got fooled on this one. One part of this is how gullible we all are (well, not you I guess), but the other part I think is that we came to *expect* this kind of stuff to happen in a world saturated with IoT devices.

@rysiek @GossiTheDog While we're at it... can we start curbing the toothbrush-shaped routers that are Mikrotik and their UDP based speedtests, please... :-| Those are like... 10g "unsolicited inbound UDP"-as-a-Service. -.-'
@rysiek Again: is it really fake? The given article states something different: https://social.tchncs.de/@jesterchen/111886824793344385

@[email protected] But the article states: "Das Beispiel, das wie ein Hollywood-Szenario daherkommt, hat sich wirklich so zugetragen." which tanslates to "this hollywood-like scenario really happened." 🤔

Mastodon
@jesterchen seems at least sus. One source, not other confirmation.

@GossiTheDog

Saw this first upon popping on this evening, followed by multiple posts about the "toothbrush botnet" - thanks for getting the word out.

@GossiTheDog

I'm totally ok with it. I laughed so hard. Rotnet and DilDoS made my day.

@GossiTheDog the german in the archive link seems to indicate the example actually happened though.
I'm more appalled by the idea of a Java-based OS than a toothbrush-based botnet.
@GossiTheDog At this point, I can enjoy the three million toothbrush botnet story whether it's true or not, and I don't know what that says about me.

@dreadpir8robots @GossiTheDog

Some stories are too good to check. :D

@GossiTheDog It wasn't the toothbrush... was it? :D

@GossiTheDog

That won't have the impact that's needed to lead to change...

Now, when a million online personal massage devices get turned into a botnet...

That will shake up the industry. 🤪

@GossiTheDog I mean, it does sound a bit unlikely because I've seen bluetooth brushes, but certainly not ones with builtin wifi.
@monsieuricon @GossiTheDog And even if some toothbrushes had wifi, I guess very few would have them directly exposed to the internet so they could be hacked.
@rogers @monsieuricon @GossiTheDog the toothbrushes wouldn't need to be hackable from the internet. They need only be on the same LAN as a previously infected Windows PC, for example.
@hyc @rogers @monsieuricon @GossiTheDog i could absolutely believe the company itself having them load configuration from an insecure head-end service.
@hyc @monsieuricon @GossiTheDog Yes. But then it would take some time to get the number up to three million hacked devices without anyone noticing.
@hyc @rogers @monsieuricon @GossiTheDog That would suggest a) a related botnet of, let's say, one million PCs (spitballing average household size at ~3 people with a smart toothbrush per person), b) really, a much, much larger PC botnet because it's unlikely that even 1% of homes have this hypothetical brand of smart toothbrush, and c) that the additional volume of traffic from 3 million low-power devices is meaningful when you have a botnet with 100,000,000 PCs in it.

@neilcar @rogers @monsieuricon @GossiTheDog good points. A bit moot now since the whole story never actually happened.

They'd make a good persistence vector tho; no one's going to suspect them and you'd never run an antivirus on them. Reminds me of back in my Atari ST days, I w̶r̶o̶saw a virus that resided in the keyboard microcontroller. It would survive a reset and reinstall itself on the first keypress / kbd interrupt.

@hyc @rogers @monsieuricon @GossiTheDog In the hypothetical toothbrush case, I think it's much more likely that the well was poisoned -- I would posit an attack against the manufacturer's poorly-secured CI/CD pipeline, perhaps via by an unpatched Jenkins vulnerability, enabling an attacker to ship a firmware update with an embedded backdoor.

This should give us pause when we consider enabling autoupdate for our smart hygiene appliances.

@monsieuricon @GossiTheDog ah, rats, I already pleaded allegiance to the SkyNet... somebody please make it so!
