I found that funny too. It sounds to me like a good way to end up with the device to analyze without being constrained by a contract or EULA prohibiting it.
IIRC "The Fucking Article". I think the expletive originally was because people "wouldn't read TFA", but eventually it just kinda became the way to refer to the article linked from a Hacker News thread.
Indeed, how convenient. If it truly did fall off the truck right while he is on a walk then there is the possibility that is a rubber duckie attack. This is basically the equivalent of leaving a USB flash drive lying around. I hope the author took the necessary precautions when reverse engineering the device. Companies like cellebrite have deep connections to certain three letter communities that staging this sort of attacks trivial.
Edit: looking up a bit more, it seems like this idiom is used to denote goods sold for cheap because they were stolen. Like "Bob is selling genuine iPhones very cheap, I fear they fell from the back of a truck".
Edit edit: I initially took it as "we won't tell how we got this", because I didn't know this idiom, but it seems several people agree with this interpretation. Not necessarily stolen, but obtained from an undisclosed source.
That isn't quite right. Although it's commonly used to describe something that's been stolen, it's more generally used to indicate that the speaker doesn't want to talk about where it came from. That's how it's been used in this article.
I thought it was an euphemism because they couldn't reveal who gave it to them. Confessing it was stolen, even as an euphemism, is too blatant to be taken seriously IMO.
