Hm... Is there any software to generate "multiple-outcome" encrypted text or other documents? It would have multiple hashes to "solve," but only one would be legitimate.

For example passw0rd would give:
Hey, there. I lost your most recent pubkey. Would you mind sending it over, again?

while a3nomalym@@kZer39jooL would give:
Hey, there. Ready to bomb X embassy in PleaseDon'tRaidMyHouse-istan?

Would be similar to Truecrypt's ability to give "fake" information with certain passwords. This could be useful as an added layer in case a PGP privkey is compromised, for example. I'd guess the initial password key(chain) would have to be given in a very private manner, like in a face-to-face kind of way, then entered with a randomly-scrambling virtual keyboard offline.

A simple XOR scheme would do the trick. I've seen the software somewhere. What it does is it can generate the required password to decrypt the desired plaintext. The password would be as long as the message. This is essentially similar to a one time pad.

You just described the zip bomb, and most modern extractors can easily detect this and not continue.

The updated method is to zip one of these giant babies, then to copy them multiple times to another zip file, then to copy those multiple times to another zip file, and you nest them very deep for a combined total size exceeding most hard drive capacities.

But, like I said, most modern archivers and extractors will detect this.

The reality is that nothing mentioned here would do what the OP wants..

.....Like the NSA is just going to run every executable they find as root/admin Roll Eyes

open a text document and add this

Code:

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

save the file with the extension .exe

This is not a malicious file but should trigger any antivirus as being malicious. "The file is a legitimate DOS program, and produces sensible results when run (it prints the message "EICAR-STANDARD-ANTIVIRUS-TEST-FILE!")."

It won't work. It's not like it's their first infected file.

If you put this string in a file and rename it to exe it will be detected as a virus by all AV:

Code:

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

From the book of old school: Create a HUGE file that just consists of one character repeated over and over (think /dev/zero piped into a 100G file). It will compress down to a few bytes when zipped, but any system expanding/decrypting it will be consuming a lot of resources.

ok I encrypted some zip bombs, some rick astley pics, some random data, and just fired off an e-mail to Virus Share asking for an invite... if I get it, then the fun begins!....

What reason did you put in for your access request?

Probably "i want to troll the NSA". VXShare is mostly full of crap, nothing useful anyways :-)

I used to keep a "virus zoo". They were all floppies locked up in a cage. I got a couple now from my office but every anti-virus can easily tag it. Pretty sure I can make some neato malware custom made trojan now that instantly nukes your drive (assuming it's windows) when executed.

I don't think this will work though, because what will happen is they will store the email and the files, but never open them or run the executables.

PS: Your plan is flawed because the NSA is not stupid enough to run potential malware in an unprotected environment, especially after you've written "there is malware attached". Also, malware is illegal, if you're doing illegal things.

Well it's more a form of protest, and also I'm assuming a lot of the process might be automated. I don't really expect them to fall for it though, it's more a "fuck you" than anything else. Also, I think they'd have an interesting time trying to show to a court that me sending an encrypted attachment to a MY friends via MY e-mail account counts as "doing something malicious" with malware.
