So probably about a decade ago at this point I was working for free for a friend's start-up hosting company. He had rented out a high-end server in some data center and sold out virtualized chunks to clients.
This is back when you had only a few options for running virtual servers, but the market was taking off like a bat out of hell. In our case, we used User-Mode Linux (UML).
UML is essentially a kernel hack that lets you run the kernel in user space. That alone helps keep things separate or jailed. I'm pretty sure some of you can shed more light on it, but that's as I understood it at the time and I wasn't too shabby at hacking the kernel when we'd have driver issues.
Anyway, one of the ways my friend would on-board someone was to generate a new disk image file, mount it, and then chroot to that mount path. He'd basically use a stock image to do this and then wipe it out before putting it live.
I'm not sure exactly what he was doing at the time, but I got a panicked message on New Years Day saying that he had deleted everything. By everything, he had done an rm -fr /home as root on what he had thought was the root of a drive image.
It wasn't an image. It was the host server.
In the stoke of a single command, all user data was lost. We were pretty much screwed, but I have a knack for not giving up - so I spent a ton of time investigating linux file recovery.
Fun fact about UML - since the kernel runs in user space as a regular ol' process, anything it opens is attached to that process. I had noticed that while the files were "gone", I could still see disk usage. I ended up finding the images attached to their file pointers associated with each running kernel - and thankfully all customers were running at the time.
The next part was crazy, and I still think is crazy. I don't remember the command, but I had to essentially copy the image from the referenced path into a new image file, then shutdown the kernel and power it back on from the new image. We had configs all set aside, so that was easy. When it finally worked I was floored.
Rinse and repeat, I managed to drag every last missing bit out of /proc - with the only side effect being that all MySQL databases needed to be cleaned up.3 -
Seems like the #1 rule of thumb in hacking is
"if you can't break it, make it irrelevant".
Seems to be true because god some of these OEM recovery discs are just... awful at securing themselves. -

WhatsApp info:+12 723 328 343
Uncovering your wife's phone secrets through the skills of a adware-like ADWARE RECOVERY SPECIALIST is a delicate and potentially unethical endeavor that should be approached with great caution. These so-called "sneaky ways" often involve highly sophisticated technological methods to bypass security measures and access private communications and data without the knowledge or consent of the device's owner. A skilled web recovery specialist might utilize advanced hacking techniques, exploits in mobile operating systems, or specialized surveillance software to surreptitiously monitor your wife's online activities, read her text messages and emails, track her location, and even retrieve deleted files - all while leaving little to no trace of their intrusion. However, engaging in such invasive and underhanded practices not only violates your wife's fundamental right to privacy, but can also severely damage the trust and integrity of your relationship if discovered. Rather than resorting to these underhanded tactics, it would be far wiser to have an open and honest discussion with your wife about any concerns you may have, and work together to address them through ethical, consensual means. Building a foundation of mutual understanding and respect is essential for the long-term health of any marriage.
