Reminds me of how you could crash a fido node by sending them some big empty files, so when they got automatically unzipped the filled of the harddrive :)
I think this kind of thing was common even a few years ago in DoS'ing mail gateways that uncompressed and scanned various archive formats. Things like really huge files when uncompressed or ridiculously deep nested directory structures.
I think most software these days is immune to such tricks, or at least has tunables to reduce the chance of such tricks causing harm.
I was doing a presentation about various bombs last year and crashed PowerPoint by copy-pasting billion laughs in a slide. Simple but extremely effective.
Not sure what is worse: that MS has Powerpoint interpreting randomly pasted XML, or that they do not have handling for excessive memory usage beyond crashing the whole program.
There was also the trick of infinitely recursive zips that kept decompressing to a copy of themselves.
Zip-bombing was such a problem for our corporate network in the late 1990s that inbound e-mail attachments were deliberately discarded for a while. Chaos ensured.
