And surely there are fools that aren't considering that their power bills will be more expensive than that and there will be some civil servant small time crooks that will try to pull this off at a government computer #-o

I used to use unused servers also, but I did have full permission at the time. 8)
One HP dual Xeon E5-2650 system was nice and good for ~280k PPD back in the day (less than half the PPD of a Vega 56 now... :-$ )

Authorized and for a good cause is the way to go. One of the cases I finalized recently was about a IT department guy who hacked (slopily) the work hours database to conceal his delays. He would get a soft reprimand for the delays, now is headed for possible dismissal #-o

Oh, I had permission, but I don't think anyone understood how much power a fleet of Pentium 4 desktops consumed under load :-$

In case you still think CCleaner is a tool worth trusting:

A user noticed that file associations were changed on the system after the installation of CCleaner, and discovered that CCleaner Browser was suddenly installed on the device and that the program had taken over file associations. The file extensions were associated with "CCleaner HTML Document" on affected systems instead of the previous application.

It's good for a laugh now that they used floppies for such a long time, but the question is, will SSDs last as long, more than 40 years?

Czech cyber-security software maker Avast disclosed today a security breach that impacted its internal network.

In a statement published today, the company said it believed the attack's purpose was to insert malware into the CCleaner software, similar to the infamous CCleaner 2017 incident

Shouldn't be a problem if it's built right. No moving parts in solid state or flash media.

Not quite as long as you think, and there are moving parts... Electrons.
5. Flash Data Retention
The level of charge in each cell must be kept within certain thresholds to maintain data integrity. Unfortunately, charge leaks from flash cells over time, and if too much charge is lost then the data stored will also be lost.


During normal operation, the flash drive firmware routinely refreshes the cells to restore lost charge. However, when the flash is not powered the state of charge will naturally degrade with time. The rate of charge loss, and sensitivity of the flash to that loss, is impacted by the flash structure, amount of flash wear (number of P/E cycles performed on the cell), and the storage temperature. Flash Cell Endurance specifications usually assume a minimum data retention duration of 12 months at the end of drive life.
http://www.ni.com/product-documentation/10126/en/

Obviously provided the drive is plugged in every few years or so, charge will be maintained. But leave any flash storage on a shelf for >10 years and there is a big risk the data will be gone.

Magnetic tape is still the best for longevity, 100+ years in a box (provided it's kept at ~20'C and max 30% humidity).
