hacking: security in practice
What are some tools or methods people use to completely wipe memory.

I’m curious on what programs or methods you guys use or are the best for completely formatting sd cards, usb sticks, hard drives, and operating systems so that no data can be recovered. This includes cookies, any metadata, files, etc. say if law enforcement seized these devices they would not find anything.

Offensive Security Tool: DeepSleep GitHub Link
DeepSleep by thefLink, is a variant of Gargoyle for x64 to hide memory artifacts using ROP only and PIC. Evasive techniques take time to produce, find and create. They are the most important steps for any attack scenario. Without evasion, you cannot perform attacks. DescriptionThis tool was created to better understand how to evade memory artifacts using a Gargoyle-like technique on x64. The idea is to set up a ROPChain calling VirtualProtect() Sleep() VirtualProtect() to mark my own page as N/A while Sleeping.

Unlike Gargoyle and other Gargoyle-like implementations, this tool relied on ROP and do not queue any APC. DeepSleep itself is implemented as fully PIC, which makes it easier to enumerate which memory pages have to be hidden from scanners.

While the thread is active, a MessageBox pops up and DeepSleep’s page is marked as executable. While Sleeping, the page is marked as N/A.

This effectively bypasses Moneta at the time of writing if DeepSleep is injected and the executing thread’s base address does not point to private commited memory.

It has been verified using the Earlybird injection technique to inject DeepSleep.bin into notepad.exe

Type make and a wild DeepSleep.bin appears.
Alternatively use the precompiled DeepSleep.bin LimitationsThis was tested on 10.0.19044 N/A Build 19044

The ROPgadgets that the tool relies on might not exist in ntdll.dll in other versions of Windows. It is probably a good idea to make use of smaller and more generic ROPgadgets and to enumerate the gadgets in more dlls than ntdll.dll. DetectionThe callstack to a thread in the DelayExecution state includes unknown/tampered memory regions and additionally includes addresses to VirtualProtect(). Hunt-Sleeping-Beacons detects this.
It may be possible to apply that metric to other C2 using a different technique to wait between callbacks.

Exposed Kubernetes Clusters, Kubelet Ports Can Be Abused in Cyberattacks

Organizations must ensure their kubelets and related APIs aren’t inadvertently exposed or lack proper access control, offering an easy access point for malicious actors.
