Endpoint Protection

Good to know that Symantec already incorporated this in their antimalware solutions. On another note, the impact of DDOS attacks has increased greatly in recent years. 10-15 years ago most of the internet was about publishing information, however, today there are so many services that we access like Office 365, Azure, Amazon services etc. so a DDOS can mean full buisness interuption for the consumers of the service not just the company that hosts the servers.

Esto no hace cuestionarnos a el rumbo que tiene que tomar la seguridad, cuando se podia pensar que la brecha de seguridad podia tener capacidad de respuesta encuentran nuevos portillo por los cuales nos podemos ver afectados.   Ese es el ciclo eterno!!!  esto no hace pensar en lo que sigue como protejo mi televisor, mis dipsitivo de trasmision al TV, o de musica, mis camara ip esto brinda un giro interesante  hacia el futuro  por  IoT, y cyual va a ser el pael de Symantec en este cambio que se esta dando y es mi parecer (nos esta tomando tarde).

A new wave of attacks involving the Mirai botnet has crippled internet access for nearly a million home users in Germany. The latest attacks used a new version of the Mirai malware (Linux.Gafgyt.B) which is configured to exploit a weakness found in routers widely used in Germany.

All great info regarding the outbreak of these IoT devices.   Since there is not a true standard on hwo these devices should be setup, the secutiry that is impmented in most of them is appauling.

No encryption, crappy default username and passwords. open ports for remote administration.

This all will just allow these botnets to just keep growing.   

Governmenets should be holding these companies who create such shoddy devices accountable for their lame security design.

"The current state of IoT security is in bad shape, and will get a whole lot worse before it gets any better. The Mirai botnet, which is powered by 100,000 IoT devices that are insecure by default, is just the most obvious and topical example.

IoT is a new and scary world.  There needs to be end user awareness provided when consumers purchase devices that are connected to the Internet.  People need to be made aware of updates and best security practices for these devices.  Maybe vendor's can push out automatic updates like they do with software products.

Remember taht things like this shouldn't be blamed on the consumer. People are told "look at this amazing device it does this service for you using the internet" and place them on their network oblivious to consequences. Many people don't understand how the internet, viruses, and hacking works exactly and they can't be expected to when these things aren't discussed approprately on a large scale in terms people can understand. Until tech manufacturers and companies begin to explain the dangers to the public and how to mitigate those factors, things like this will occur more and more.

That's very true, but it can't always be blamed on the consumer. People are told "look at this amazing device it does this service for you using the internet" and place them on their network oblivious to consequences. Many people don't understand how the internet, viruses, and hacking works exactly and they can't be expected to when these things aren't discussed approprately on a large scale in terms people can understand. Until tech manufacturers and companies begin to explain the dangers to the public and how to mitigate those factors, things like this will occur more and more.

I've already been following most of these recommendations on my home network.  I've started doing Nessus scans on my devices as well just to make sure that things are not vulnerable.

Looks like the same vulnerability has been used in the UK: http://www.theregister.co.uk/2016/12/01/hull_router_attack/ Same router brand exploited in the same way. That said, it looks like this is a management port that should have been secured by the ISP prior to being sent out to customers. Would be interesting to see if this is something that was documented.

As a security professinal we know the risks of using IoT.

The end user however doesn't share the same mindset.

Lucky for them Symantec has their back protecting them from their unknown...

Step 1 - research

Step 2 - update/patch

Step 3 - pray

Just crazy. An IoT device is basically an device that connects to the Internet. And to think that people connects it to the Internet without any protect scares me. For example, the recent case where a police officer plugs his Iomega drive and it got exposed to the Internet, leakking data of sensitive data about security investigations by Europol.

All IoT device NEED at least by default, FORCES the user to set a strong password before even allowing it out of the wild Internet. With thatm it will reduces the impact of infected devices.

Sadly, many hardware/software makers are not clued up on this. They just make it work, release it and not think abouty the long term impact. They need to act & prevent from this happening BEFORE they even started making their device!

Most of us focused a lot on the endpoint, automate the patching whenever Microsoft release hotfix on Tuesday, look like it is far from enough, the healthy PC can lose the internet connectivity if the router is attacked by the botnet. that also remind me how many companies still not run antivirus on Linux and Unix systems, maybe it is time to change,    

It's good that the router can auto download updates or this could have been a bother to fix.

Hopefully everyone will be informed how to do it or can get help

I read things like that and these warnings are fine for someone like me who is familiar with technology and the ramifications associated with its haphazard use but I always think back to someone's grandparents, or some teenager working at Best Buy who is explaining how to configure your new "Smart" microwave.  The more that these trivial devices become network aware, the more the attack surface is going to grow until we create a second, "Computer-Only" internet.  I don't see any light at the end of this tunnel.

These types of devices are being used more and more, I feel like they could easily be connected to your network without people realising the risk. I like the comment above and network discovery is probably the most important, if you don't know what you've got lurking how can you stand a chance at protecting yourself. Great article.

While step #1 is great (research what is going on with that IoT device you are looking into) I feel like many of the devices that get connected to your network are done w/o IT Security knowing or doing the research.

How many Chromecasts or SmartTVs or HVAC systems are in your network that your IT Security Team doesn't know about?

Doing the discovery in my mind is the more important thing.  I read a report that stated there are 25% more devices on the network than the Security Team knows about.  Thus Network Discovery in my mind is more important.  Understanding what is on yoru network should be a starting point

Very interesting post @Symantec!  There seems to be a big trend on IoT devices being targeted lately...

In the future, maybe we will see some kind of solution from @Symantec that prevents these devices being targeted.  :D 

Another interesting post by symantec. Good to raise awareness of the Mirai botnet, the scale of its use and devices it can effect. Scary how it uses IoT and these can often be vunerable. At least if you're runnig Symantec you can feel a bit safer.

It amazes me how many folks attach an IoT device to their network without realizing the security implications. It's also unfortunate that the vendor doesn't architect their product(s) with security in mind. Until that happens, these sorts of things will continue on. At least if you're runnig a Symantec product, you can feel a bit safer.

I am glad, Symantec is taking a tough stand against Mirai.

A DDoS attack is an aggressive sort of DoS attack, where DoS is short for denial of service.

A DoS is a bit like getting into the queue at the station to buy a ticket for the next train, only to have a time-waster squeeze in front of you and slow you down.

Mirai, as the malware is known, is badly programmed and unfinished, but that doesn’t matter.
