You read your chips' datasheets that go in detail on pinouts and protocols. You use logic analyzers that capture signals and programmatically decode a multitude of protocols from those signals. When you don't know what are the pin

Nice to see another static analysis tool. It looks like the compilation database is only used for discovering source files, without any additional cross translation unit analysis [1]. Even if you don't plan on implementing data flow tr

The author is referring to limitations in analysing banking: > Ghidra supports the 8051 architecture but not code banking. Usually in these ISAs an I/O port or a register sets the bank number, so any processor module should be able

Which drives and parameters for the READ BUF SCSI command yielded the expected 2366 bytes per sector? I imagine that it was combined with seeks to each sector before reading from the buffer (as it would be harder to isolate multiple sectors

Nice work Dmitry, looking forward to read your next article. The later model Pixter Multimedia had the full memory space accessible via JTAG, which is how some carts and even boot ROM got dumped a while ago [1], is it the same deal with Pix

I found their ELF format specification to have a decent coverage, even if not completely exhaustive (e.g. some debug info isn't breakdown after a certain point, but it just might be incomplete rather than limitations). > Things may

Besides the implementation effort in building from scratch, it also opens you up to unknown unknowns, while the limitations of mature software are better defined. Just because Jepsen didn't test other alternatives doesn't mean the

Nice, also check these projects that target earlier versions: * Rust9x: Compile Rust code for Windows 95, NT and above: https://news.ycombinator.com/item?id=31112273 * Rust on MIPS64 Windows NT 4.0: https://news.

Without discrediting the author, as it's always cool to share these findings, was anyone actively looking for this over 27 years? A lot of the times, it just happens that someone was the first person that even bothered trying digging i

Can you elaborate on that "little more work", given that resizing on demand isn't sufficient for this use-case, and predictive scaling is also out of the question?

AWS autoscaling does not take your application logic into account, which means that aggresive downscaling will, at worst, lead your applications to fail. I'll give a specific example with Apache Spark: AWS provides a managed cluster vi

Sleep obfuscation seems to be viable because scanners only execute periodically. I'm not very familiar with Windows internals, but why don't these scanners hook the VirtualProtect calls and only then scan the associated memory reg

x/w is a gdb command to dereference and print (x) 1 word-sized data (w) at the address given by the expression. So 0x08001ea1 was the unaligned address stored at $rsp + 8, passed as argument to __lll_lock_wait.

I wonder if MAME would work as an open-source alternative for these simulations. The built-in debugger and memory views cover most of that, and it doesn't take much to write a minimal driver that messes with some input file [1]. But if

Unfortunately, there's little curation of interesting debugging case studies or "debugmes". You can try to scavenge bug trackers, but they aren't optimized for this, just a bag of itches users want to scratch. Neither ar

The implementation was not saving any of the ymm registers, you can see this in the bug report's attached patch. It also took me a while to get, because the last snippet in the writeup only highlights the ymm1 register, instead of show

Supposedly there's an easter egg in Windows CE's Solitaire [1] that has never managed to surface, beyond someone posting part of the credits text in a comment. No screenshots, videos, or any other evidence of its existence. It&#x2
