From the first amateur hackers in the 80s till 2011 when international cyber sabotage is a reality, viruses have illustrated the frightening potential of human ingenuity. Here’s a brief look back how computer viruses have evolved through the most important outbreaks of the last 25 years.
The first PC virus
1. Brain, 1986
More than a decade before anyone had ever heard of Napster, the first PC virus was designed to fight piracy. The author who came up with the word “cyber,” William Gibson called Brain “basically a wheel-clamp for PCs.”
Basit and Amjad Alvi created and marketed medical software in Lahore, Pakistan. They were interested in two things. First, they wanted to check the multi-tasking functionality in the new DOS operating system (so-called “TSR” systems). Secondly, they wanted to see if there are security vulnerabilities in DOS compared to other operating systems such as Unix.
When they realized that DOS was quite vulnerable, they had the idea to write a snippet of software that would monitor how the software and the floppy disks move around. Brain spread virally via 3 1/4-inch disks, and within weeks, the Alvi’s had to change their phone numbers.
25 years after the creation of first PC virus, in early 2011, F-Secure’s Mikko Hypponen went to Lahore, Pakistan to visit the address in the code. He found the Alvi brothers still there, running a successful business. The following video includes the first video interview Amjad and Farooq have given about Brain ever.
Some early fun
Most of the early viruses were variations of the same theme: “Gotcha!” Users knew they’d been infected because that was exactly the point. Like a digital pie in the face.
2. Stoned, 1987
Created by a high school student in New Zealand, Stoned was supposed to be harmless. It simply displayed the message “Your PC is now Stoned!” on your screen. However, as the first virus that infected a PC’s boot sector, Stoned established that viruses could control a computer’s function from the moment it turned on. Bob Dylan should be proud.
3. Form, 1990
Form became one of the most widespread viruses ever. On the 18th of each month, it produced a clicking sound from the PC’s speaker whenever a key was pressed. Annoying, but harmless.
Other variations on this early innocent sort of “gotcha” virus included V-Sign, which displayed a V on your screen. The Walker virus showed an elderly man walking across your screen. Elvira scrolled text in the “A long time ago, in a galaxy far, far away” style a la Star Wars. And then there was Joshi. Every year, on the Joshi’s birthday, this eponymous virus displayed a birthday message. The machine refused to boot up until the user typed “Happy Birthday Joshi.”
4. Michelangelo, 1992
Michelangelo would override everything on a hard drive on specified dates. A variation of Stoned with much crueler intentions, Michelangelo was probably the first computer virus that made international news.
5. VCL, 1992
Virus Creation Laboratory made it easy to whip up a malicious little program by automating virus creation using a simple graphical interface.
Early MS-DOS and PC-DOS viruses did some damage to PCs, usually intentionally, but virus writers soon began to actively seek to wreak havoc by actively disabling computers.
6. Happy99, 1999
Happy99 was the first email virus. It greeted you with “Happy New Year 1999” and emailed itself to all contacts in your address book. Like the very first PC viruses, Happy99 did not cause any real damage, though it did spread to millions of PCs around the world.
7. Monkey, 1993
A distant relative of Stoned, Monkey secretly integrated itself into data files and spread seamlessly. It was the early ancestor of a rootkit, a self-concealing program, and it prevented booting from a floppy disk. When it was removed improperly, Monkey prevented any sort of booting at all.
Upgrading to Windows
In the early 90s, viruses became macro viruses and took on Microsoft’s new OS, Windows. Written in the same languages as applications like Microsoft Word, macro viruses appeared in late 1995. In just three months, they became the most common virus type in the world.
8. Concept, 1995
The first virus that infected Microsoft Word files, Concept became one of the most common viruses in the world because it could infect any OS that could run Word. Share the file, share the virus.
9. Melissa, 1999
Allegedly named after a female exotic dancer familiar to the virus writer, Melissa combined a virus and an email virus. It infected a Word file then emailed itself to all contacts in the user’s address book and became the first virus to span the globe in only hours. Melissa combined the jokey motivations of the early virus writers with the destructiveness of the era. This virus inserted comments from “The Simpsons” into users’ documents. Not so bad. But Melissa could also send out confidential information without the users’ notice. D’oh!
Not long after Melissa, Microsoft virtually eliminated macro viruses by changing how its Visual Basic macro language works within Office applications.
Crashing the network
Before firewalls, computer worms generated huge amounts of network traffic, disrupting systems by pure volume. These worms generally did not affect individual users but they could rock the infrastructure of both private businesses and governments.
10. Code Red, 2001
The first worm that spread without requiring any user interaction at all and thus spread around the world in minutes, Code Red hid from detection and carried out various functions on a cycle. On Days 1-19, it spread itself. From the 20th to the 27th, it launched Denial of Service attacks on various addresses including the White House. And from the 28th day till the end of the month, it rested.
10. Loveletter, 2000
The computer worm that broke millions of hearts, Loveletter is still one of the biggest outbreaks of all time. It spread via email attachment and overwrote many of the crucial files on the PCs it infected. This outbreak was an incredible successful attempt at social engineering. Using the promise of love, it convinced millions to open the attachment, causing an estimated $5.5 billion in damage worldwide. Guess there are a lot of people out there looking for a little love.
12. Slammer, 2003
Network worms require just a few lines of code and vulnerability to spark real world trouble. Slammer took down Bank of America’s ATM network and 911 services in Seattle. Even the air traffic control system was not immune.
13. Sobig, 2003
Sobig was a quick improvement on Fizzer (see below). Some versions waited for a couple of days after infecting a machine before turning affected machines into e-mail proxy servers. The result? Massive spam. AOL alone reported stopping more than 20 million infected messages on one day.
14. Mydoom, 2004
Mydoom spread over email and the Kazaa Peer-to-Peer (P2P) network. It set new records but was old school in the sense that the motive wasn’t monetary. Mydoom executed Distributed Denial-of-Service attack on one particular website and opened a backdoor on infected computers, which left the machine open to remote access.
15. Sasser, 2004
Sasser came in through a vulnerable network ports and slowed or crashed networks from Australia to Hong Kong to the UK.
Money. Money. Money.
In the last decade, the motive for virus writing has become obvious: Money. The technology still tends to be variations on a theme, but modern virus writers utilize advanced user psychology and social engineering to draw users into traps that they’d probably been warned about several times.
16. Fizzer, 2003
Fizzer was the first virus designed to make money. It arrived as an infected attachment. Once opened, it took over infected computers and forced them to send spam.
As the real-world impact of viruses was felt in the early 90s, business, government, software makers and the Internet security industry put fires out and collaborated to minimize threats. Virus writers, too, evolved to avoid detection, creating advanced malware that could even be programmed to be patient.
17. Cabir, 2003
The first mobile phone virus in history, Cabir targeted Nokia smartphones running the Symbian operating system. It was spread via Bluetooth and proved that whatever shape PCs evolve into, they will be targeted.
18. SDBot, 2003
SDBot was a Trojan horse that bypassed normal security to secretly control a computer. It created a backdoor that allowed the user to do several things including sniff for passwords and the reg codes of games like Half-Life and Need for Speed 2.
19. Haxdoor, 2005
Haxdoor was another Trojan horse that sniffed for passwords and other private data. Later variants had rootkit capabilities. Even Brain used techniques to cloak itself, but Haxdoor employed far more sophisticated methods. A modern rootkit can turn a computer into a zombie computer that can be controlled without the user’s knowledge, sometimes for years.
20. Sony BMI, 2005
In 2005, one of the biggest record companies in the world had the same idea that the Alvi brothers had in 1986: Use a virus to prevent piracy. On its audio CDs, it included a music player program and a rootkit that controlled how the owner could access the audio tracks. The result was a media firestorm and a class-action lawsuit that ended with Sony offering users money and free downloads.
Computer viruses have had real world effects for decades, but in 2010 a computer virus may have changed the course of history.
In November of 2010, Iranian President Mahmoud Ahmadinejad confirmed that a cyber attack had indeed caused problems with their nuclear centrifuges. And in January of 2011, Russia’s ambassador to NATO said that Stuxnet could cause a “new Chernobyl.”
21. Stuxnet, 2010
An unusually large Windows worm—about a 1000% larger than the typical computer worm, Stuxnet most likely spread through USB device. It infects a system, hides itself with a rootkit and sees if the infected computer is connected to a Siemens Simatic factory system. If the worm finds a connection, it then changes the commands sent from the Windows computer to the PLC Programmable Logic Controllers, i.e., the boxes that actually control the machinery. Once running on the PLC, it looks for a specific factory environment. If this is not found, it does nothing.
F-Secure Labs estimates that it would take more than 10 man-years of work to complete Stuxnet. This complexity and the fact that it could be used to impair the ability of a centrifuge to enrich uranium while providing no monetary gain suggest that Stuxnet was probably developed by a government—though which government is unclear.
22. Storm Worm, 2007
Machiavelli said it’s better to be feared than loved. Seven years after Loveletter, Storm Worm capitalized on our collective fear of bad weather and first spread generally via an email message with the subject line “230 dead as storm batters Europe.” Once the attachment was open, a Trojan backdoor and a rootkit forced the PC to join a botnet. Botnets are armies of zombie computers that can be used to, among other thing, send out tons of spam. And this one sucked in ten million computers.
23. Mebroot, 2008
Mebroot was a rootkit built to hide from the rootkit detectors that quickly became part of many Internet security suites. It is so advanced that if it crashes a PC, Mebroot will send a diagnostic report to the virus writer.
24. Conficker, 2008
Conficker quickly took millions of computers all over the globe. It exploits both flaws along with Windows and weak passwords along with several advanced techniques. Once a system is infected, further malware can be installed and the user is even prevented from visiting the website of most Internet security vendors. More than two years after it was first spotted, more computers are infected by the worm every day. F-Secure’s Chief Research Office Mikko Hypponen has said that in many ways Conficker is still “a great mystery.”
25. 3D Anti Terrorist
This trojanized “game” targets Windows Mobile phones and was spread via freeware sites. Once installed, it starts making calls to expensive numbers leaving you with large charges. This strategy of hijacking a mobile app or cloaking a malicious app is still new, but it’s likely to one of the main ways the virus writers will attack mobile devices.
Where are we 25 years after Brain?
In 2011, a PC running an updated version of Windows 7 is quite secure, especially when running updated security software. Now that we know more about viruses, we know how to fight them, and ideally prevent them. So, hopefully, in 25 years viruses will have gone the way of macro viruses and we won’t have to make a new list.
Many techie terms in the headlines lately. Supercookies, supertrackers, HTTP headers and X-UIDH. If you just skim the news you will learn that this is some kind of new threat against our privacy. But what is it really? Let’s dig a bit deeper. We will discover that this is an issue of surprisingly big importance. Cookies are already familiar to most of us. These are small pieces of information that a web server can ask our browser to store. They are very useful for identifying users and managing sessions. They are designed with security and privacy in mind, and users can control how these cookies are used. In short, they are essential, they can be a privacy problem but we have tools to manage that threat. What’s said above is good for us ordinary folks, but not so good for advertisers. Users get more and more privacy-aware and execute their ability to opt out from too excessive tracking. The mobile device revolution has also changed the game. More and more of our Internet access is done through apps instead of the browser. This is like using a separate “browser” for all the services we use, and this makes it a lot harder to get an overall picture of our surfing habits. And that’s exactly what advertisers want, advertising is like a lottery with bad odds unless they know who’s watching the ad. A new generation of supercookies (* were developed to fight this trend. It is a piece of information that is inserted in your web traffic by your broadband provider. Its purpose is to identify the user from whom the traffic comes. And to generate revenue for the broadband provider by selling information about who you really are to the advertisers. These supercookies are typically used on mobile broadband connections where the subscription is personal, meaning that all traffic on it comes from a single person. So why are supercookies bad? They are inserted in the traffic without your consent and you have no way to opt out. They are not visible at all on your device so there is no way to control them by using browser settings or special tools. They are designed to support advertisers and generate revenue for the mobile broadband provider. Your need for privacy has not been a design goal. They are not domain-specific like ordinary cookies. They are broadcasted to any site you communicate with. They were designed to remain secret. They are hidden in an obscure part of the header information that very few web administrators need to touch. There are two ways to pay for Internet services, with money or by letting someone profile you for marketing purposes. This system combines both. You are utilized for marketing profit by someone you pay money to. But what can and should I do as an ordinary user? Despite the name, this kind of supercookies are technically totally different from ordinary cookies. The privacy challenges related with ordinary cookies are still there and need to be managed. Supercookies have not replaced them. Whatever you do to manage ordinary cookies, keep doing it. Supercookies are only used by some mobile broadband providers. Verizon and AT&T have been most in the headlines, but at least AT&T seems to be ramping down as a result of the bad press. Some other operators are affected as well. If you use a device with a mobile broadband connection, you can test if your provider inserts them. Go to this page while connected over the device’s own data connection, not WiFi. Check what comes after “Broadcast UID:”. This field should be empty. If not, then your broadband provider uses supercookies. Changing provider is one way to get rid of them. Another way is to use a VPN-service. This will encapsulate all your traffic in an encrypted connection, which is impossible to tamper with. We happen to have a great offering for you, F-secure Freedome. Needless to say, using Freedome on your mobile device is a good idea even if you are not affected by these supercookies. Check the site for more details. Last but not least. Even if you’re unaffected, as most of you probably are, this is a great reminder of how important net neutrality is. It means that any carrier that deliver your network traffic should do that only, and not manipulate it for their own profit. This kind of tampering is one evil trick, throttling to extort money from other businesses is another. We take neutrality and equal handling for granted on many other common resources in our society. The road network, the postal service, delivery of electricity, etc. Internet is already a backbone in society and will grow even more important in the future. Maintaining neutrality and fair rules in this network is of paramount importance for our future society. Safe surfing, Micke PS. The bad press has already made AT&T drop the supercookies, which is great. All others involved mobile broadband providers may have done the same by the time you are reading this. But this is still an excellent example of why net neutrality is important and need to be guaranteed by legislation. (* This article uses the simplified term supercookie for the X-UIDH -based tracker values used by Verizon, AT&T and others in November 2014. Supercookie may in other contexts refer to other types of cookie-like objects. The common factor is that a supercookie is more persistent and harder to get rid of than an ordinary cookie.

It's like a press conference anyone can join from anywhere. And even if you don't have a question, you can upvote the ones you don't like and downvote the ones you do. President Obama did one. Snoop Dogg/Snoop Lion did one. An astronaut did one from outer space. And our Mikko Hypponen will sit down for his second Reddit AMA on December 2 at 9 AM ET. If you have something you've wanted to ask him about online security, great. If not, here are five resources that document some of Mikko's more than two decades in the security industry to prod you or prepare you. 1.

If you like sailing and tall ships, I can recommend this podcast about Pam Bitterman’s book Sailing to the far horizon. It’s a great story about the last years of the community-operated ship Sofia, covering both a lot of happy sailing and the ship’s sad end in the early eighties. But this is not about hippies on a ship, it’s about how we record and remember our lives. In the podcast Pam tells us how the book was made possible by her parents saving her letters home. Perhaps they had a hunch that this story will be written down one day. Going on to state that e-mails and phone calls wouldn’t have been saved that way. That’s a very interesting point that should make us think. At least it made me think about what we will remember about our lives in, say, twenty years? We collect more info about what we are doing than ever before. We shoot digital pictures all the time and post status updates on Facebook. We are telling the world where we are, what we are doing and what we feel. Maybe in a way that is shallower than letters home, but we sample our lives at a very granular rate. The real question is however how persistent this data is? If we later realize we have experienced something unique enough to write a book about, have our digital life left enough traces to support us? Pam wrote the book about Sofia some twenty years later. A twenty year old paper is still young, but that’s an eternity in the digital world. Will you still be on the same social media service? Do you still have the same account or have you lost it. Does the service even exist? And what about your e-mails, have you saved them? How are your digital photos archived? You may even have cleaned up yourself to fit everything into a cheaper cloud account. Here’s something to keep in mind about retaining your digital life. Realize the value of your personal records. You may fail to see the value in single Facebook posts, but they may still form a valuable wholeness. If you save it you can choose to use it or not in the future. If you lose it you have no choice. Make sure you don’t lose access to your mail, social media and cloud storage accounts. That would force you to start fresh, which usually means data loss. Always register a secondary mail address in the services. That will help you recover if you forget the password. Use a password manager to avoid losing the password in the first place. Redundancy is your friend. Do not store important data in a single location. The ideal strategy is to store your files both on a local computer and in a cloud account. It provides redundancy and also stores data in several geographically separated locations. This is easy with younited because you can set it to automatically back up selected folders. Mail accounts have limited capacity and you can’t keep stuff forever. Don’t delete your correspondence. Check your mail client instead for a function that archives your mail to local storage. Check your social media service for a way to download a copy of your stuff. In Facebook you can currently find this function under Settings / General. It’s good to do this regularly, and you should at least do it if you plan to close your account and go elsewhere. Migrate your data when switching to a new computer or another cloud service. It might be tricky and take some time, but it is worth it. Do not see it as a great opportunity to start fresh and get rid of "old junk". If you are somewhat serious about digital photography, you should get familiar with DAM. That means Digital Asset Management. This book is a good start. Pam did not have a book in mind when she crossed the Pacific. But she was lucky and her parents helped her retain the memories. You will not be that lucky. Don’t expect your friends on Facebook to archive posts for you, you have to do it yourself. You may not think you’ll ever need the stuff, just like Pam couldn’t see the book coming when onboard Sofia. But you never know what plans the future has for you. When you least expect it, you might find yourself in a developing adventure. Make yourself a favor and don’t lose any digital memories. Safe surfing, Micke
