Virus Development

[Quik]

I like the trojan that encrypted files and charged cash for the decryption. Any Asian kid can put "^_^_^__^_^_^" in a file and be 'witty'.

But they don't all exploit a program designed to protect you!

It's all of those reasons together that make it fun :)

I'd sue him, it works the other way arround. =p

On a side note, guys, I'd apreciate it if you discussed virus development, instead of laughing at funny ones (by no means am I saying that isn't funny).

Trojans are so much more fun then viruses, but sadly easier to detect. Really the only fun I'd have with a "virus" would be if it detected when there was a window opened, and suddenly ended the process, but eh, those sorts of things are fun to do to people you dislike.

Or if it disable's control of the users mouse, that would be a hell of a lot of fun.

Do you know the proper definition of a Trojan?  I think what you're talking about is a remote-access-trojan, which is a subclass of Trojans.  A Trojan, like the Horse, is a program that looks nice but has an evil side.  It sneaks in under the guise of an innocent program, then infects the machine. 

Anyways, I was thinking.  Joe, those aren't viruses.  They're just annoyances.  By definition, a virus infects programs or files already on your computer.  Here is a definition from the "Free On-line Dictionary of Computing":

A program or piece of code written by a cracker that "infects"
one or more other programs by embedding a copy of itself in
them, so that they become Trojan horses. When these
programs are executed, the embedded virus is executed too,
thus propagating the "infection". This normally happens
invisibly to the user.

Well, I don't know if it qualifies as a program, but this infects your bootsector. =) (the latter examples, I mean)

Manual Override virus is the funniest, it stopped all the fans on your comp and made it calculate pi.

I've seen some malicious trojans that overclocked the cpu to the max and have heard stories about it burning holes in the motherboard.

[Newby]

Those sound like fun.

Still a falling under the definition of a trojan nonetheless.

But they aren't "trojans" in general, which is what you said.  And they aren't easier to detect; in fact, by the definition of a Trojan, they're harder to detect. 

Joe - you don't "infect" anything, you just overwrite.  There's a difference.

Romi/Quik - eww, user accounts shouldn't even had access to do that kind of thing, and there's a good reason :)

A remote control trojan would however, because it's obviously sending out packets, if you turn off anything else that is needs to connect to the internet to work, you can easily find out. Now if you'd answer my AIMs that would be great.

It's not "remote control trojan", the class of trojans is named "Remote Access Trojan", or "RAT". 

I don't understand what you mean by the next sentence.  I know of very few trojans or viruses (yes, viruses, virii isn't a proper word) that turn off your internet connection since they're usually trying to stay hidden. 

When I got your message you were offline so I closed the Window.  Plus, I haven't answered anybody this morning, I've spent all morning going to the store, eating breakfast, fixing my aunt's computer, helping my mom paint a room, and helping my stepdad clean the swimming pool.  I'm not exactly sitting here waiting for messages.

You also never answer any other message I send you.

And, for the remote access trojan thing, it's very easy to tell, as seen in the link below.

If you run a packet sniffer throughout the night, with every other program that needs to connect/has the ability to connect to the internet to work (i.e. Steam, AIM, MSN, Firefox, whatever), you can tell if you do have something sending out information about your computer on a regular basis, because chances are it's going to do it atleast once every so and so number of hours, and if it wants to send anything, there's going to be another IP involved, which a good packet sniffer will pick up. (Note: I never said ever it'll get rid of the trojan (remote access, don't get technical on this iago) it'll just give you some way of knowing you have one.)

That's a lot of work for trying to justify an ignorant mistake, Screenor.  Maybe you should just accept iago's right? O_o
