Not a surprise there — I’m sure most of their budget goes to advertising and scare tactics, rather than actual development.

@rhmelis: That’s actually pretty awesome. I wasn’t sure if a lot of major Anti-Virus programs actually did catch them or not.

A simple concept, but interesting.

Instructions for Unzipper
1. Write a 1.
2. Write a billion billion billion 0s
3. Write another 1.
4. Rinse and repeat

Pure genius.

A lot of people will actually use hex editors, to edit the file AFTER it has been zipped up, this helps keep the filesize small when you’re creating it.

That should be of an interested further reading for people who would like to.

At least I’d hope it would lock up an AV scan. Anything that crowbars my scanner is not something even I’d be dumb enough open.

Decompression bombs have been around for a while. A lot of anti-virus programs wouldn’t recognize what it was, and if you tried to scan it, they would actually freeze up.

It’s even more fun when that is not joke but seriously unoptimized program. I had encountered app once that had some extra data packed in 10Kb zips… Which unpacked to 100+Mb each.
