A fuzzy issue of responsible disclosure

> In general, plugging in a USB thumb drive for which you don't have complete confidence in the provenance of the image is dangerous

It's worse than that. My fairly new Fairphone 4 started randomly rebooting recently. I was all worried, as is usual when a £650 piece of hardware starts malfunctioning, and then I discovered that the cause was the SD card plugged into the phone, which had aged out and gone read-only (and possibly messed up its contents in other ways?) at a bad instant and had produced an ext4 fs that reliably caused a panic (well, it panicked my desktop box so I suspect the same sort of thing was happening on the phone). The provenance of this fs was perfectly normal, only ever written on two devices both of which I control: all it took to corrupt this FS image was aging hardware.

(Unfortunately I threw the card away before I remembered the existence of e2image, or I'd have sent you a nice metadata dump. Whoops...)
