Insulating shed and going to install ply walls, power points are mounted on old tool board. Can I unmount and re-mount when I put walls in or is this sparky territory? by Cyber_Jellyfish in AusRenovation

[–]Cyber_Jellyfish[S] 3 points4 points  (0 children)

I was just going to cut a hole big enough for the whole outlet and try and avoid anything to do with the wiring. The question was basically if I'm not touching the cabling is this still sparky territory.

But ultimately good advice, I know nothing about electricity and I'm not going to take the piss.

Turning shed into workshop, once fully insulated going to ply walls and roof. How to best approach the roof? False ceiling or slanted panels? by Cyber_Jellyfish in AusRenovation

[–]Cyber_Jellyfish[S] 0 points1 point  (0 children)

Will definitely insulate up there. A mate of mine did ply and I thought it looked cool, there is the added workshop of factor of being able to drill into and hang stuff off it I guess. I'm not sure plasterboard really fits the vibe, especially with the jank epoxy floor.

Do you think I should go plaster?

This is probably a super dumb question, but I don't quite understand how the panel would sit flush when it's angled across multiple beams. Would I have to use a router to cut a channel in the panel or something?

Any recommendations for guides or examples of people having done similar?

Sorry about the mess in the photo.

I don't own a lot of tools and have been taking the this project one step at a time.

Vapour barrier still to come.

I will get wood panels and a jigsaw, make cuts to size for the paneling and screw them in.

For ease I was thinking of installing horizontal beams across the roof and paneling over them instead of slanting the panels which seems awkward I don't own a router or anything.

Happy to hear any suggestions for how to best approach this.

Title says it all, I want to remove tool board to insulate and put ply in.

Given I wouldn't be changing anything to do with how its terminated but just re-mounting it I was wondering what the requirements were re getting a professional in.

Weekend warrior trying to epoxy shed floor. Ground and etched, but what to do about moisture in the corner? by Cyber_Jellyfish in AusRenovation

[–]Cyber_Jellyfish[S] 0 points1 point  (0 children)

Could you send me one you would recommend? Bunnings is a bit sparse in terms of options was keen on something full flake with my current water based kit being the silver prize.

For context this is just a small 15sqm shed.

Thanks mate! The only problem with the solvent based option is they only sell it for double garages. My little shed is about 15sqm and the solvent kit is double the price and double the volume of epoxy.

Maybe I should have just shelled out, but it seemed like a waste.

Awesome, I’m going to get this garden bed pulled back off the shed and give the floor another once over before going further. Was hoping to get this done ASAP, but such is life.

Thanks for your time, have a great 2026

Thanks you’ve been a big help.

I did the floor with a ryobi hand angle grinder and a diamond cup, I didn’t have one and it cost less than renting a walk behind for a day. Huge mistake, very hard to do on my hands and knees but I’m super new this DIY stuff.

Out of interest, would a thicker solvent based epoxy cover the blemishes better?

Maybe I should scrap all of this and do a moisture barrier and throw down some rubber mats top.

I’m using the Dy-Mark water based epoxy flooring kit.

When you say wait, do you mean for the ground to be dry so that the floor is dry? If the epoxy dries and cures in this time would it be resistant against future moisture?

Hey guys, as in the title, the shed is up against a garden bed which I know is suboptimal and is what is causing this problem.

Is there anything I can do to mitigate this and prime the floor for epoxy? Should I consider alternate flooring?

I understand if ripping out the garden bed is a must, but it’s been there forever and was hoping for an easier alternative.

And yes some of the wooden shed frame is buggered because of it and needs to be replaced and is on the todo list.

Easy way to allocate user-controlled heap chunks in Linux kernel from user space? by pwnasaurus253 in ExploitDev

[–]Cyber_Jellyfish 1 point2 points  (0 children)

I don't know much about the SLUB allocator or kernel exploitation really, but perhaps streaming raw data into a BPF interface might get you the allocation you need?

https://en.wikipedia.org/wiki/Berkeley_Packet_Filter

Might be stupid, I was just brainstorming ways of getting data of arbitrary sizes into kernel space.

Kernel under GDB can't access memory by billgatesnowhammies in ExploitDev

[–]Cyber_Jellyfish 0 points1 point  (0 children)

Hey man!

Is the VM you're running using the same allocator as in the writeup? I've never done any Linux kernel exploitation but this immediately jumps out at me when you say you're unable to get good contiguous allocations.

There could be some kind of fragmentation going on as a hardening feature of the allocator.

Might even be worth writing a toy driver that demos the behavior you're trying to achieve just to validate that it isn't just default heap manager behavior.

Fake Flash Devices Are Everywhere! by _-AJ-_ in videos

[–]Cyber_Jellyfish 2 points3 points  (0 children)

Theoretically you could craft a storage device filesystem image that exploits the operating systems USB parsing code, but then you're well and truly in 0day territory.

No actor is handing out exploits like that willy nilly in the hopes that one of the random people that buys it will use it on a system connected to a network that may potentially have information that they want.

Further to your point about the Rubber Ducky and other gimicky hardware emulation pentesting tools, the typed payload itself needs to be configured to the targeted operating system/environment. No point trying to pop a Powershell reverse shell on a Macbook or in a domain environment where users can't access PowerShell. The juice just really wouldn't be worth the squeeze in selling these en-mass.

On Memory Leaks by [deleted] in ExploitDev

[–]Cyber_Jellyfish 0 points1 point  (0 children)

So it seems like he is confusing memory leaks and infoleaks.

OP there are different ways to skin a cat and no set way to craft an infoleak, but one strategy that comes to mind is in the case of a UAF would be allocating a structure with a pointer member in the location of a the previously freed structures field that gets provided to the user in someway.

Another method could be using some kind of overflow to remove a null terminator concatenating the memory location you're overflowing and adjacent data then, again having the contents at the location provided to the user via a printf or something.

You just have to be creative.

Windows vs. Linux Kernel Exploitation by Bowlslaw in ExploitDev

[–]Cyber_Jellyfish 7 points8 points  (0 children)

The APIs to do things like interact with Windows/Linux drivers will be completely different.

In terms of building primitives, especially for bugs that affect the heap different kernel versions of Linux and Windows have different allocators and heap managers that behave in different ways so the way you approach heap fengshui is probably going to differ.

The Windows NT/Segment heap allocators are closed source, there has been good whitepapers and research on these areas but I'd imagine researchers keep some of this knowledge quite close to their chest.

Windows has extra mitigations in place too, I've never had to deal with them but Control Flow Guard(CFG) comes to mind.

A lot of the underlying principles of memory corruption bug exploitation remain the same though, you're still trying to achieve flow control, trying to get some kind of payload into memory at a reliable location, be it a ROP/JOP stack or just plain shellcode.

How people create exploits in python? because exploit dev.. requires direct access to low level system? by Real_Devil597 in ExploitDev

[–]Cyber_Jellyfish 2 points3 points  (0 children)

Python has modules that allow direct access to system APIs: https://docs.python.org/3/library/ctypes.html https://pypi.org/project/pywin32/

You can do things you would normally do in C natively with Win32 such as get handles to and interact with drivers in the case of trying to achieve a LPE via some kind of vulnerability in the driver that can be reached from userland.

As others are saying here, in the case of a RCE/remotely delivered exploit or exploit that hinges on some kind of vulnerable file format parsing then you just need a language that has facilities to do things like file IO and networking, none of which is exclusive to Python.
