Some random and ultimately pointless commentary

Someone I know worked somewhere they were told to keep confidential files on their desktops rather than the C drive. Edit - file as in data file not physical file, and desktop as in Windows desktop, not their physical desk.

When the power goes off, the decryption key field that is generated by the processor fan stops, and the HDD then loses the ability to decrypt it's magnetically stored data. (With SSD drives, it's all down to little tiny Leprechauns who live in the SATA cable)

Remind me to integrate this stuff into the drivers my 82C55 DIY IDE controller.
I have lived with several Zen masters - all of them were cats. His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Ah, that explains why I can never move a hard drive to another computer. The decryption key is specific to the unique quantum fluctuations of every computer's fan! ;) As to Leprechauns, I always new there was magic in this world!!!

Hype!! I found the only true guarantee for security here: [OneSafe Software – Official Website – Utility software for PC & Mac](https://onesafesoftware.com/software/) It makes your PC safe! But! I can see in the photos that it also makes Mac's safe! (Even if the ⌘-key is black.) :mad: What really bugs me is that frauds like this appear on big sites, in this case Yahoo! They should really be able to maintain a minimum degree of advertising hygiene.

Crazily, even after a couple minutes of no power, a good 80% of the image that had been in memory was still there and recognizable. We're talking minutes, not seconds, and not SRAM either.

Locking your computer is not an effective security method (since files are not automatically encrypted).

This is probably meant to be read "instead of anywhere else on the C drive". There is a Windows Policy to backup the desktop at power off, and restore it at power on, so this makes somehow sense. If my computer crashes at work, I will have my desktop back including all the content just by logging on a new computer.

No, they thought the desktop was some kind of special entity of the operating system that only the person currently logged on could access. They had no idea it was just a folder on the drive and the desktop an application that renders those files as icons.

I don't know what it is specific to the topic of cyber-security, but all of the training that's been foisted upon me has contained similar nonsense. This in itself would be bad, but that same training usually contains at least one dangerous bit of technically inaccurate information. Anyhow, the "currently offline" site that is "Always Online" made me burst out laughing...seriously, spittle was involved :) As I'm in the midst of some drudge work right now, the laugh was much appreciated.

Not knowing the exact situation, I might still give them the benefit of doubt and assume they were using folder redirection. You can set up folders - and the desktop is a perfectly good candidate - to be rerouted to some server share. I'm not a domain policy expert, but I'd be surprised if it couldn't be done and that some organizations are doing exactly that today.

While that may be true, I was spewing anger over the general phenomenon of malware ads on very big sites.

That's one reason why memory was so much slower back then. They used actual capacitors to retain the charge in the memory bit and apparently they had rather low leakage current so they could hold it for a while.
Leakage current has always been minuscule but the surface of the CMOS, which is the source of the "parasite capacity" used to actually store data in DRAM dropped by a huge factor, so it became relevant.

You don't necessarily need a password to get a locked running OS to do stuff for you as the current logged in user (e.g. via a USB attack), and since it can read the encrypted files... If they've enabled the full-drive encryption, and especially the encryption build into the hardware of 2.5" drives, then even if you have physical access, you're going to need the password before you can read the data on the drive if the computer is off when you get there.

So "private" information then? If it's private to me, I'm not sure it should be made "publicly" available.

I understand what you are saying, but perhaps since the latter is a proper noun (i.e., capitalized), it's not really referring to a state, thus those terms can co-mingle. :confused:
