Internet of default passwords … – did it improve at all?

Posted by jpluimers on 2017/10/26

Just over a year after this got posted, I wonder what the current state of affairs is. Did it get a lot worse or just a little (as when writing this in November 2016 my guess is that it won’t get any better soon):

To repeat +Thomas Mueller ‘s words:

Internet of default passwords …
Sounds bad until you realize that it’s even worse. There are millions of devices out there that can be or have already been compromised and can get their owners into deep shit, without their owners even doing anything wrong. And keeping your virus scanner up to date won’t help at all (it doesn’t really protect your PC either, but that’s a different story).

Just watch the first 10 minutes of the video, but be warned, it might ruin your day.

Via +Joe C. Hecht:

I found this to be a superior product – If you are into security, this episode was worth a listen. I hear they are into talking about home servers too. I like that.

How to turn on your lights the Philips way

Posted by jpluimers on 2017/06/23

This was too funny to let go unnoticed: [WayBack] How to turn on the light at home, Philips Version – Kristian Köhntopp – Google+.

It was shown during [Archive.isGoogle Cloud Next 2017 in Amsterdam and immediately reminded me of The Big Bang Theory – How to turn on a lamp below.

A few notable entries from the comments:

  • Wie viele Server braucht man bei Philips, um eine Glühbirne zu wechseln?
  • Apple macht das wohl ähnlich, hier dient ein AppleTV oder ein iPad als “Bridge zur Bridge”.
  • They’re at least honest — the icon of the cloud in the upper left prominently displays a “waiting” circle animation. I also notice the use of the word “looks” rather than “works” in the title, which is probably also accurate.

This is why nobody upgrades their consumer IoT, router, etc firmware…

Posted by jpluimers on 2017/06/02

Just one example; it applies to virtually all consumer IoT and routers I know: upgrading is hard especially if it’s undocumented on how to keep your configuration.

Opinion: The Internet of Shitty Things — Kommentar: The Internet of Shitty Things | heise online

Posted by jpluimers on 2016/11/20

I translated the heading and one quote; if you want to read further in English: Google translate does a good job on the text.

HVAC thermostats, bread baskets, coffee machines: The net is full of things, which make no sense at all and nobody needs. The Internet of Things is a huge pile of shit, says Clemens Gleich.

There are no error-free systems, there are maximum undetected errors.

German original:

Heizungsthermostate, Brotkörbe, Kaffeemaschinen: Das Netz ist voll mit Dingen, die da nur Quatsch machen. Braucht kein Mensch. Das Internet of Things ist ein riesiger Haufen Scheiße, meint Clemens Gleich.

Es gibt keine fehlerfreien Systeme, es gibt maximal unentdeckte Fehler.

Rob Graham 🦃 on Twitter: “1/x: So I bought a surveillance camera https://t.co/HbmPzrZgFK”

Posted by jpluimers on 2016/11/20

Conclusions:

  1. Always put your IoT devices behind a firewall
  2. Isolate each IoT device into it’s own “world” that can communicate as little with the rest of your networks as possible
  3. Preferably isolate each set of IoT devices that do need to communicate in their LoT (Lan of Things)
  4. Use Ad-Blockers

Of course Rob tried many webcams to find a vulnerable one. And putting telnet port 23 to the open is not the best idea, but people do that or get an indirect infection by some piece of JavaScript from an Ad-Network that searches for local vulnerable devices. That’s how the internet works!

I don’t have #IoT. I have #LoT. LAN of things. 

Posted by jpluimers on 2016/10/24

Interesting thought:

I don’t have #IoT. I have #LoT. LAN of things. My gadgets have no default gateway and cannot talk to the internet. Simple. Now I’m hoping for broad supp… – Jan Wildeboer – Google+

Devices in a separate LAN (or VLAN) with no default gateway and some firewall rules to access them from your regular LAN and update them through FWUPD an open source firmware update.

Sounds like a dream? We should all make it come true!

The IoT strikes back again: half a million IoT devices killed DYN DNS for hours, but fixing this will be hard

Posted by jpluimers on 2016/10/22

Less than a month after The IoT strikes back: 650 Gigabit/second and 1 Terabit/second attacks by IoT devices within a week the IoT struck back again: an estimated half a million IoT devices was used to perform multiple DDoS attacks against Dyn Managed DNS that took around 11 hours to resolve.

Google DNS appears to

Google DNS appears to “live” near me in Amsterdam

High availability usually involves a mix of DNS TTL and/or BGP routing. That’s typically how CDN providers like Cloudflare work (it’s one of the reasons that global DNS servers like Google’s 8.8.8.8 appear near to you and over time routes – some MPLS – to it change). Short DNS TTL can help CDN, requires a very stable DNS infrastructure and is similar to but different fromFast Flux network.

Last months attacks were on a security researcher and a single ISP. The Dyn DNS attack affected even more internet services (not just sites like Twitter, WhatsApp, AirBnB and Github). So I’m with Bruce Schneier that Someone Is Learning How to Take Down the Internet.

Handling these attacks is hard as the DDoS mitigation firms simply cannot handle the sudden increase of attack sizes yet. BCP38 should be part of mitigation, but the puzzle is big and fixing it won’t be easy though root-causes of bugs change as a lot of research is in progress.

I’m not alone in expecting it to get worse though before getting better.

On the client side, I learned that many users could cope by changing their DNS servers to either of these Public DNS Servers:

  • OpenDNS 208.67.222.222, 208.67.220.220, 208.67.222.220, 208.67.220.222
    • OpenDNS does a good job of handing “last known good” IPs when they can’t resolve.
  • Google Public DNS 8.8.8.8, 8.8.4.4
  • Level 3 DNS 4.2.2.1, 4.2.2.2, 4.2.2.3, 4.2.2.4, 4.2.2.5, 4.2.2.6

Some more interesting tidbits on the progress and mitigation on this particular attack are the over time heat-maps of affected regions and BGP routing changes below.
