WannaCry and the malware hall of fame

The WannaCry worm has wrought havoc around the globe for days however it is not the primary to unfold so far, so quick. The history of Technology and the online has been often punctuated with the aid of outbreaks and infections.

The Morris worm

In 1988, simply because the internet was once starting to capture on, computer science pupil Robert T Morris was once desirous about simply how large it had grown. He wrote a small software that travelled around, logging the servers it visited.

Bugs in his code made it scan the net very aggressively so each server ended up operating a couple of copies of the worm. Every replica used up just a little bit of processing power so the servers regularly slowed to a halt.

The scanning visitors clogged the net making it nearly unusable. It took days to scrub up the an infection.

Mr Morris was caught and located responsible of computer fraud and was once fined $10,050 (£7,785).

These Days, he’s a pc scientist on the Massachussetts Institute of Know-how (MIT).

The Morris worm has one peculiar parallel with WannaCry. Mr Morris was once the son of the NSA’s chief scientist and the WannaCry worm is according to code stolen from the NSA.


In May Just 2000, thousands and thousands of Home Windows customers discovered never-ending copies of an e mail bearing the topic line ILOVEYOU of their inboxes.

It spread up to now and so fast thanks to the booby-trapped file attached to it. Opening the file fired up the small software it contained which sent a copy of the identical message to the entire addresses present in a victim’s address guide.

It was once additionally helped to spread as a result of all these messages perceived to come from someone a recipient knew. And the topic line made people curious too.

ILOVEYOU rattled around the globe for almost two weeks racking up greater than 50 million infections. High-profile victims included the CIA, Pentagon and UK Parliament.

Philippine college students Reonel Ramones and Onel de Guzman have been found to be the creators of ILOVEYOU. They escaped prosecution because there were no computer misuse regulations within the Philippines at that time.

Code Purple

Energetic in July 2001 and named after the fizzy pop being inebriated through the researchers who discovered it, this worm targeted web servers running Microsoft IIS device.

It led to severe disruption and many web pages, small businesses and bigger companies have been knocked offline for a while.

No-one has ever been named as Code Crimson’s creator although on servers it compromised it displayed a message suggesting it originated in China.

Like Wannacry, Code Purple exploited a recognized Computer Virus and caught out servers that had no longer been updated with a patch.

SQL Slammer

This worm emerged in January 2003 and used to be so virulent that it is believed to have slowed down visitors across your entire net because it unfold.

Slammer was a tiny application, roughly 376 bytes, that did little more than create random internet addresses and then send itself to those locations. If it hit a computing device working a vulnerable version of Microsoft’s SQL server, that machine bought contaminated and then began spraying out more copies looking for more victims.

The slowdown was because of net routers struggling to deal with the huge amounts of traffic Slammer generated whereas in the hunt for out new hosts.

Once More, a patch used to be to be had for the Trojan Horse it exploited however many people had no longer applied it despite it being available for six months.


This Home Windows electronic mail worm from January 2004 is believed to carry the current file for spreading quickest – infrequently stunning given that it used to be reputedly created with the aid of skilled spammers.

It labored so well thanks to a artful little bit of social engineering. The Email bearing the worm was designed to appear to be an error message. This fiction used to be aided by using the message’s attachment which purported to hold a duplicate of The E-mail that did not arrive.

Opening the attachment kicked off the malicious code that re-despatched the identical message to everybody in a victim’s handle ebook.


November 2008 saw the appearance of this virulent worm which hit up to 15 million servers running Microsoft software. It ran rampant and caught out hospitals, governments, the military and lots of companies.

The outbreak was so dangerous that Microsoft offered a $250,000 reward for any knowledge resulting in the identification of the worm’s creator. No-one has ever been recognized as its originator.

A patch closing the loophole it exploited used to be launched with the aid of Microsoft a couple of month after it regarded. Even as of late, 10 years on, information traffic generated with the aid of machines contaminated with Conficker ceaselessly flip up.
