Trying to understand my modem/router - Part 2

Hey guys, I started my journey some time ago here: https://forum.tuts4you.com/topic/39557-getting-docsis-cable-modem-firmware/ My ultimate goal would be to find a remote code execution on the system. The reason you may ask, is twofold: 1. Learning 2. Being able to access the router without opening it up would be nice. But now I am much further in trying to understanding my cable modem / router but I still have so many questions unanswered... What I managed to find so far: *The router has 2 main microcontrollers (one Puma 5 chip and one Realtek chip), what I suppose is that the Puma 5 chip deals with the Modem part and the Realtek chip with th…

Motorola 68360 JTAG

Anyone got any experience working with the CPU32 or CPU32+ architecture? I'm working on a target that runs its code out of flash and swaps some data in and out of SRAM, but usually not executable code...so I have no breakpoint abilities. I'm having to reflash the target ( lengthy process ) each time I want to try a change from static analysis and it's really frustrating only being able to single step the CPU and not have it stop anywhere. I'd kill for just a single breakpoint at this point. I tried hardcoding in some stops (bgnd opcode) just as a compiler would to force the CPU into background mode to break, but the changes of the executable code are causing checksum…

As ARM these days is becoming ever so popular on embedded devices..static analysis always doesn't get it done. Here's a couple of useful tools to allow you to run some code in an IDA database if you want to emulate simple subroutines as if you were debugging them with a JTAG...without any debugging hardware. https://github.com/cseagle/sk3wldbg support: x86 x86-64 ARM ARM64 MIPS MIPS64 SPARC SPARC64 M68K This one allows you to bind python style variables to the arm assembly and run it https://github.com/36hours/idaemu Example1 This is easy function for add. .text:000000000040052D public myadd .text:000000000040052D myadd …

dumping serial SPI and I2C chips
by secursig- 0 replies
- 7.8k views
thought I would post this since it's extremely useful for working on some embedded targets. the basic principle is you use a cheap logic analyzer to intercept read requests to the chip ( usually from the microprocessor of your target ) since some designs they store special information in small chips on PCB, like serial number, password, settings, etc. after the CPU reads all the addresses its interested in over the SPI or I2C bus your logic analyzer sees the waveforms and captures the data. then this utility will convert the logic analyzer file to a binary dump of the chip by reconstructing the flash memory contents so you can see what's inside and load into IDA. very use…

CPU32 Embedded Reversing JTAG
by secursig- 0 replies
- 7.2k views
Anyone have any experience working with ABATRON BDI2000 or BDI3000 on 683XX based architecture targets? These are the ones that use the CPU32 instruction set. I also have other JTAG pods that support CPU32, but the support for it is kind of dead these days since over thing has gone the way of ARM. The ABATRON I could never do much with except use the single hardware breakpoint, dump registers and memory. Still pretty useful, but it sucks having to clear the breakpoint and re-add it every time you want to step over any call in code. Soft breakpoints are not an option usually because the target devices usually boot from a rom or bootloader in flash which of course is not di…
