You’ll definitely get lots of login attempts. I used to have a port 22 ssh, hundreds of attempts per day.
Would be interesting to see what post login behavior was.

Wanna bet they expose SSH on port 22 to the internet on their “critical” servers? 🤣
Sure, but the author makes it sounds like thats its their standard way of doing things, which is insane.
And if you do have a misconfiguration, the rational thing is to fix that, not dump the entire platform.
If the hypervisor or any of its components are exposed to the Internet
Lemme stop you right there, wtf are you doing exposing that to the internet…

If your goal is to interrupt her usage to avoid excessive usage, would a pomodoro timer help?
I dunno if that can be setup to force lock the screen or something, but maybe its helpful? Depends if its easy to override?
That’s for the motherboard replacement, not the bootloader unlock.
They’ve already unlocked and bricked their device, so they need a new motherboard.
For free? Probably not.
Wireguard has been audited by some University groups, maybe contact one of them:
Doesn’t even startup on my box, but doesn’t crash the kernel or system either, just regular application crash
There really is 2 NSA’s, with conflicting goals. Keep Americans secure, and collect everyone elses data. Its a difficult line to walk. The first half does produce really good advice and tools, but is undermined by the second halfs image.
I fortunately never learnt Ida due to cost, so I have no idea what is missing, but ghidra was a godsend for CTFs. Suddenly reversing challenges were accessible and easy.
https://code.nsa.gov/# - Lots of useful stuff here.
Kernel shouldn’t crash, and anything running in memory will be okayish, but it definitely will get less and less stable. It won’t be possible to start new processes.
I have a Linux install on a USB SSD with a flakey connection, if I bumped the cord the root would unmount. It was fairly resilient, but graphics would slowly start disappearing. I’m fairly sure I could cleanly reboot as long as I had a terminal open, but its been a while, so maybe I’m misremembering.
Still, the overall system becomes pretty useless, so i guess its fair to call it a crash
There are rust libraries to send signals, might be better to use those rather than calling bash. eg. https://docs.rs/nix/latest/nix/sys/signal/index.html
I’m guessing if input was “”, then it would sigkill all processes? Less confident, but some functions behave slightly differently in an interactive console vs a non interactive, maybe ps
has a different format when used non interactively?
Aside, you want three backticks and a newline to get code formatting :)
Ah, that definitely would feel like a crash. Sent kill signal to cgroup accidentally? Or just iterate over all processes and signal them all?
OPs example was task management, which doesn’t require kernel modules.
Doesn’t explain OPs task management example. And won’t crash the kernel, just make things unresponsive
That won’t crash your kernel, and I was more curious about the OPs example. Task management is basically reading some files, and sending signals, it should be near impossible to crash the system.
How are you crashing your system?! Crashing program sure, but the entire system?
Ghidra. Boom, here is 90% of ida pro. Enjoy.
The malware argument is a bit weak, if your router is vulnerable to something it’ll likely be found and pwnd in a matter of minutes, so turning it off a night won’t really save you. And once a patch is released, it’ll be reverse engineered in a few hours/days, so ideally you want patches as soon as they are released.
Using your own device is usually a good idea anyway, telco stuff is usually pretty mediocre. And as soon as your device is slightly custom, it becomes a less valuable target.
There are two reasons to avoid a union:
If you are well looked after by your company and are treated fairly, there is no need to create a union.
Apple may be in this category?
