The Computer Virus Turns 25 in July

bl8n8r writes "In July of 1982, an infected Apple II propogated the first computer virus onto a 5-1/4" floppy. The virus, which did little more than annoy the user, Elk Cloner, was authored in Pittsburgh by a 15-year-old high school student, Rich Skrenta. The virus replicated by monitoring floppy disk activity and writing itself to the floppy when it was accessed. Skrenta describes the virus as "It was a practical joke combined with a hack. A wonderful hack." Remember, he was a 9th grader when he did this."

Script kiddie age?

Is there any information on the average age of people who have written the major viruses of the last couple decades? Has this age gone down over time?

Don't forget the Lehigh Virus

[R2.0]

I was at Lehigh when this was released. One of the first self propagating viruses, with a time delay to allow for greater infection, that was actually destructive. It was sort of a non-event to the users there; imagine my surprise when I looked it up years later and it figures prominently in virus history.

Still, sounds like something very harmless. You should see Amiga-related (not AmigaOS related as much of the population used Amiga as game console) viruses, like Saddam. I think orginal Saddam could be proud this piece of horrible software.

Then, with release of AmigaOS 2.04, we had new kind of viruses. They would spread like... er... viruses? They patched all systems calls dealing with resources loading and all your fonts, device drivers, libraries, executables was infected. I still remember Happy New Year 1996 -- it took me two days with no sleep to clean my disk. Anti-virus software that could deal with it was designed by someone who hated people. First, you passed what it should scan. Then, when process started, at every instance of virus it would start FROM THE TOP. And it would say "Oh, you have an virus. It was deleted. Continue?" You HAD to click it to start again. My Libs: directory had over 6500 shared libraries. All infected.

(Yes, I realize it was done to prevent from recursive infection. This should not be the case since all system vectors was checked all the time by the very same program.)

I think this guy was hired to do 'Allow or Cancel' component. :-)

Not the oldest.

I had an Atari 800 back in 1979. In 1980 I took a small piece of malware someone else wrote and turned it into a virus which would remain memory-resident and self-replicate. After formatting any diskette the victim inserted into the drive, it wrote a hidden file to infect any machine the disk was then used on. This was a payback for the people who were getting pirated software free and then turning around to sell it. I'm pretty sure I still have the source code for it somewhere.

I'm not claiming mine was the oldest because I'm sure someone did something similar on the old heavy iron even earlier than my little "payload" as we called then it.

1988 Morris internet worm

[peter303]

That was the first virus I remember, but its just 19 years old. It paralyzed the internet when it was released. But then the Net just had a few thousand nodes, most of them in the university. The worm was supposed to count nodes by sending a copy of itself to every entry in the host table, but the author forget to account for duplicates and circularities. So it just replicated until it filled the process spaces and internet bandwidth.

The first virus? I do not think so.

Sorry, but Creeper beat that Apple II virus by about 10 years.

Furthermore http://www.viruslist.com/en/viruses/encyclopedia?c hapter=153310910 states that such ideas and programs already started in the 40s and 50s.
