Great format. This is so clearly described and spoken that I listened to it a SECOND time, as a “podcast”. Thanks for going that extra “kilometer” and describing what’s on-screen.

Excellent documentation and walk through. I love your stuff.

When you showed your "Fuzzer" i totally lost it. Haven't had such a good laugh in years in this topic. But if i think about it some more, it is just about perfect. Easily accessible (but not perfect) entropy to cause spasms in badly written code. Being more or less available on any machine with and OS (no, Windows is not an OS, it's malware) means you can do preliminary tests even in absence of your "fav tools".

Glad to see you back :)

keep up the great work. sometimes people feel like so many things are common sense and dont explain the things that help people understand stuff. thank you for such a detailed video

Incredible work. I'm blown away to see this entire research from start to finish, including the thought process. Well done. I hope to one day be able to do what you do!

Awesome stuff! waiting for the 2nd video.

It's shocking how it's making unsolicited DNS queries for random domains for completely unrelated companies. Concerning. If I was watching the WAN and saw these random requests coming from a router, I'd be concerned it was compromised in some way, not operating normally with stock firmware...

conn-indicator needs to know when it has network connectivity, and the programmers chose this way to verify it. This is normal, and in this specific case quite benign in our opinion, as the DNS domains it is trying to query are well known. The mistake here was to make their own DNS parser (why TP-Link? WHY???). They could have used a shell script and standard utilities for checking connectivity, and a separate binary for controlling the LED lights! If this makes you worried, then have a look at what your phone, Windows or MacOS computer is doing for the same connectivity checks, without any user program running or any kind of user interaction, you will be VERY surprised 🙈

My Provider had a Damage in a Knot where a Car crashed in.... first the internetconnection was lost, a few Minutes....after That it was ok for a few Minutes.... then it crashed again and was a longer Time out of Order. Since that I can not connect my Handy and my TV but every other Device works as usual. One Thing is that my Handy and the TV dont find the Port anymore... How is that possible?

I feel like $20k is a paltry sum to pay hackers for a hardware (firmware?) Bug on a device sold to hundreds of thousands of people

I have no clue wtf your saying half the time but, I still watch hoping something will stick. something better than nothing, right? I love hearing the actual thought process of the hack as if you're going threw it for the first time. I like this very much.

What toolsets(s) are you using ie caller??

Seeing my exact router in this vid is funny and terrifying

TP-Link be like: - Unit testing? Nah bro, we in China trust each other

If the CPU used by a server had as its lowest-level language a managed language, say for instance a Lips CPU, where there is no memcpy and other such potentially bug-infested C code behind the Lisp code, then how would you find a vulnerability?

Nice presentation. You touched on a couple points that are just outside my full understanding. Specifically, at the segmentation fault, what makes a memory address "unmapped". Is it unmapped because it is outside the allocated stack frame? Anyway, really nice work! Thank you.

@FlashbackTeam

Жыл бұрын

Hi Matthew, glad you liked the video! You are correct. When a program starts, it allocates ("maps") memory ranges for the stack, the heap, libraries, the executable code, etc. These regions are not contiguous in memory. For example let's say a stack of 0x1000 in size, mapped in memory starting from 0x10000, which means its range is 0x10000 to 0x11000. Then we have a heap of size 0x1000, which is mapped at 0x12000 to 0x13000. In this example, if we try to access memory at 0x11001, it will cause a segmentation fault, as that memory is not mapped to either the heap or the stack. This was exactly what happened in the example in the video, albeit with different (more realistic) addresses.

Part 2 when? :D

Why KZread am recommended video this me not know but watch interesting brain capacity limited open to expansion thank you I will sub

Vendor-supplied router firmwares that use ancient kernel and code is commonly recognized to be insecure. This is why I always use OpenWRT

It seems almost impossible for a regular person to be able to protect themselves over someone accessing their computer or phone. After having all of my data stolen from a big tech company it has been so difficult to feel safe.

Thanks this was very helpful! I wonder why they used DNS instead of ICMP? Surely DNS was never intended for such things?

@khatharrmalkavian3306

Жыл бұрын

More and more places blocking ICMP these days. Moreover, even if they wanted to ping a well known CNAME, it would still require a DNS query, so just doing the query is more efficient, since it's only checking for connectivity.

I won the last 3 years WASP competition, but my method for doing this cannot be disclosed because of the damage it will cause, here is a sample of what i know: bluetooth follows the standard made by cisco on their routers where you make one the master the rest just follow. the same applies in Bluetooth yet here the clients that connect allow you root access to them as the technology defined.

It didn't occur to me until watching this video, but AI would be amazing at reverse-engineering like this. Renaming functions and variables and creating comments based on context is already so close to how AI models interpret code.
