#Reverse #engineering "fun":

HTTP-NTLM or Negotiate (same issue)...
... fails to authenticate Client1 on Server1
... authenticates Client2 on Server1
... authenticates Client1 on Server2
... fails to authenticate Client2 on Server1 when passed through Fiddler
... fails to authenticate Client1 on Server2 when passed through Fiddler

So. Fiddler and Client1 have the same issue in their HTTPS stack when talking to Server 1.

HTTP stream is equivalent, as is encrypted HTTPS seen in Wireshark.

Right now I'm working on an ssh remote tunnel reverse shell which will allow me to ssh into a remote system even if it doesn't have a static ip or port forwarding..

Every 5 minutes the remote system checks a file on the secondary system to see if it should set up the remote tunnel and send email notification.

Then I can use that tunnel to ssh into the remote system from the secondary system.

When I'm done checking the remote system I kill the tunnel process.

#ssh #remote #reverse shell

That guy hacked his air purifier, reversed part of the Android app, then the PCB, downloaded the firmware and reversed everything .. to integrate it to HomeAssistant! :o

Didn't know about MessagePack nor esp32knife.

Intel 當年的 Pentium FDIV bug 居然還有新的發現...

三十年前的 Pentium FDIV bug 居然還有新的發現冒出來：「Intel's $475 million error: the silicon behind the Pentium division bug」。

Gea-Suan Lin's BLOG · Intel 當年的 Pentium FDIV bug 居然還有新的發現...三十年前的 Pentium FDIV bug 居然還有新的發現冒出來：「Intel's $475 million error: the silicon behind the Pentium division bug」。 先快速複習當年的情況，Intel 在 Pentium 上面引入了新的除法演算法，這個演匴法用到了查表的技術，但因為 script 裡面有問題，導致表格裡面缺了五個值有錯誤，所以造成計算錯誤：「The Truth Behind the Pentium Bug (1995)」。 An engineer...

👀 Reverse Engineering and Dismantling Kekz Headphones

nv1t.github.io/blog/kekz-headp

Blog · Reverse Engineering and Dismantling Kekz HeadphonesClose to a year ago, I stumbled upon the Kekz Headphones, which seemed like an interesting approach on the whole digital audio device space. They claimed to work without any internet connection and all of the content already on the headphones itself. They are On-Ear Headphones, which work by placing a small chip (I call them “Kekz” or “Cookie”) into a little nook on the side and it plays an audio story. I was intrigued, because there were some speculations going around, how they operate with those “Kekz”-Chips. I invite you to join me on a journey into the inner workings of those headphones. We will talk about accessing the encrypted files on the device, breaking the crypto and discovering disclosure of data from customers.
