New ransomware wipes every file larger than 128 KB (mashable.com)

For larger files, the malware generates four of these codes. But due to a programming error, it keeps overwriting each new code with the previous one in the same slot, like writing four different combinations on a single sticky note and keeping only the last one. By the time it's done, three of the four codes are gone forever. The scrambled data they correspond to is permanently unreadable for the victim, security researchers, and the attackers themselves.

They called me crazy for insisting on ensuring all of our companies files compress to 10,000 separate 64KiB xz compressed files. Well who's laughing now?!

Best part about doing this is you can get 4 files to a DD 5.25". That, alone, quadruples the speed of performing off-site backups.

Never underestimate the bandwidth of a truck full of disks doing 75 mph on the highway.

That’s a wild bus factor though

You mean if the bus gets hit by a bus?

[–] JasonDJ@lemmy.zip 7 points 1 day ago (1 children)

This is how you drove down probability.

The risks of Steve getting fatally hit by a bus are, statistically, very low.

However, there are even fewer busses getting fatally hit by other busses.

Ipsp facto, lower risk, extra 9s.

That's risk tolerance 101.

Further, your DD 5.25" could have been set up in a RAID array so you could have 3 buses full of diskettes and only need two buses to reach the destination to rebuild the whole file system.
