Here is a general question about Worms, Trojans and Virus's? Why hasn't there ever been one that simply deletes peoples porn? it seems like that would be the end of civilization.

Suddenly the internet has no porn and neither do you.

I hope you're kidding op, you cannot define porn from non-porn using software, I mean it is technically possible if you give parameters like skin colors in videos or moaning in the audio, but it would still require a botnet for every file that needs to be analyzed... but what's the point of deleting pr0n besides pissing people off? You need to be a uber bigot to waste this many resources and time just for deleting maybe 0,01% of the total internet porn, before the anti-viruses get updated.

Even if the world wide supply of internet porn was suddenly deleted, there are backups on disks and cd's and plus we can always make more its not that hard really..

New porn is constantly getting created and uploaded, so you'd have to infect every porn uploader to fully deprive someone of porn. If you had the power to do that why not do something more useful like get rid of all video streaming sites and start your own saying your immune to hackers

Actually since most people(idiots) categorize and seperate their porn from regular files it would be quite easy to make a file searcher hat looks for obvious folders, even easier when you account for obvious file names containing keywords.

Why? Why does anyone make viruses. For the fuck of it.

Maybe back in the day, but now, most all malware is written because people want to make money, or steal some other kind of valuable.

There are less and less "troll" malware.

Its definitely possible though, and I would certainly lmfao my fucking ass off if someone made that.

Because if you found a way to reliably detect porn vs. noporn you'd be doing something a hell of a lot more productive/lucrative than writing a prank virus.

One thing I've been wanting to write is a skin-tone detector for images.
Maybe with some vague humanoid shape function too. Although for some images humanoid shape will not help you.

As a porn filter- ever thought about just doing it by filename?
You could delete a lot of porn that way. Trawl empornium or something for a list of keywords to find, and delete everything that matches certain filename types. Like different pornsites name their files differently, and if you can find regex matches you could reasonably assume it was porn.
Or if it just has 'fuck' or 'pussy' in it then you could pretty much assume it was porn.
A list of pornstar names would help too.

This.

You would have to use some kind of machine learning technique to get a program to differentiate between a porn file and a non-porn file. It would probably take a massive amount of computing power. It would need to analyze audio and video. It'd have to detect nude bodies engaging in intercourse. And even then it might get confused with different kinds of porn.

1st step: you would need a botnet. It would have to be very reliable with thousands if not millions of nodes.

2nd step: The combined resources from the botnet would need to be used for recon. At this phase the program needs to analyze a particularly large dataset of porn videos and pictures. This is where the program "learns" what porn is.

3rd step: Testing. The program must be tested against a large database of porn. It should successfully identify porn videos and images within a reasonable margin of error.

4th step: All you have so far is a program that identifies porn. You now need to write a worm that can infect multiple platforms. You have to research different points of entry and exploits.

5th step: Testing. Test your points of entry/exploits. Test against different virus scanners.

6th step: Strengthen malware against defenses using knowledge from step 5.

7th step: Deployment.

All in all this would take years to develop. It would need a huge team and lots of money. This is on the same scale as stuxnet. It will never happen.

Here's a proposed solution:

1. Do a reverse image search and find the source of the picture.

2. Check if the websites that tend to post this picture are listed by net-nanny, is filtered by sfw google searches, and other related adult filters.

3. Using the results from #2, use a machine learning algorithm to apply weights to each technique and classify into porn or not porn.

4. Realize that a virus that deletes all pictures and videos from a person's computer will also delete all the porn from their computer and disregard 1 through 3 as a fun, but educational way to learning about machine learning.

That's actually pretty good but if we're talking about deleting ALL porn then I'd use your solution plus the machine learning solution. Have to be thorough. In my mind, the main obstacle is the money and resources needed to get this off the ground.

It would be hilarious to see people bitching about their missing porn though. I can only imagine what the dicks on Fox News would say.

just fucking delete everything, its like 5 or 6 lines, you can even make it fall from the users folder so you just focus on personal documents and can fuck everything up faster; and instead of deleting truncate, its easier, faster, and less obvious.
making so much of a fuss to look for porn makes it weaker, there is like 100 ways for it not to work

It could instead be supplied with parameters describing porn well enough to procedurally generate vast quantities of porn automatically if used differently.
