One process starts another, which then starts another and another etc. until RAM/CPU is taken up. And the bad thing is, they are extremely easy to make, it only takes 2+ lines in DOS (the more lines the more new windows), or 3+ lines in BASIC* (again, the more lines the more windows) *I use a compiler/library called PureBasic Well I went looking around the internet and found out that it is what they call a ‘fork bomb’.

IE kept opening pop-ups every second. I couldn’t close the windows and they just kept opening. I probably had at least 40 pop-ups before I re-booted. Windows task manager wouldn’t even work, and my computer was running so slow that it would have taken a minute to calculate 1+1. Is there a name for this type of pop-up denial of service? it happen me to ,a week ago,and he it's right : MILITANTPLATYPUS Says: December 21st, 2007 at 9:34 am yep, adware.

BitTorrents are usually large files that are stored in tiny bits, and are stored on many computers. The torrent file (usually *.torrent) is a small file telling your torrent application where to find the bits I think. Anyway it downloads those bits and stores them in the files, then it downloads more bits. It should only hold in memory the bits that it is downloading and the .torrent file, so I don't see how torrents could be decompression bombs. I don't know how you could avoid them, just make sure you are downloading from a trusted scource. Anybody could make one with a bit of knowledge with hex-editors.

If you actually LOOKED at my EXAMPLE I showed you how compressed files are compressed. You don't NEED a 100gb file, all you need is a hex-editor or something. Then you create an empty archive. Then you write something like: 99999999999999999999999 0 and that is your huge file. It only takes 24 bytes of disc space to write, but when decompressed it takes up 93132257461547.85gb of memory (The remainder was so huge I had it shortened to .85) and if i only had 6kb of disc space i could still make a HUGE decompression bomb. And with 24kb of disc space, well, that is totally unbelievable. And there you have it, YoDavid. (BTW in my previous post i rushed and my name was misspelt. My name isn't dannt, it is Danny) I just DID!!! If you actually LOOKED at my EXAMPLE I showed you how compressed files are compressed.
