The Life of Mikko Hyppönen


Mikko Hyppönen entered the world of cybersecurity in 1991 when the internet was just beginning to play a role in the lives of everyday people.

Back then, he was a security researcher at F-Secure (then called Data Fellows), a Finnish company known for developing the world’s first heuristic antivirus software. He developed the company’s research lab, becoming its chief research officer in 1999.

Hyppönen in 2003: The Year of the Virus

Hyppönen rose to international fame in August 2003, when he and his team at F-Secure identified and took down numerous pieces of sophisticated, widespread malware.

That year, Hyppönen says, was the worst in virus history, and August was its worst month.

The Blaster Worm

The chaos began on August 11 with the Blaster worm, which exploited a security hole in Windows XP and could spread automatically to any vulnerable computer with an internet connection. Blaster hijacked its victims to conduct a DDoS attack against the Windows Update website, consuming system resources so heavily that many infected computers began rebooting uncontrollably.

Within hours of Blaster’s release, Hyppönen’s team had identified it. They coordinated with other antivirus companies to warn users about the worm and urged them to download Microsoft’s official security patch.

The Welchia Worm

Computer worm

The following week, a new worm emerged: Welchia, a “helpful worm” designed to spread itself to as many computers as possible, remove the Blaster worm, and install security patches to prevent reinfection.

But Welchia was coded to clog up networks, caused random reboots, and interfered with enterprise IT functions. Many rail systems on the US’s east coast were disrupted, as were Air Canada’s check-in system and countless personal computers.

Hyppönen and his team worked quickly to create a tool to stop the Welchia worm, then put it online as a free download.

But another appeared as soon as that problem was dealt with, and this was the worst of them all.

The SoBig.F Worm

In January of 2003, Hyppönen identified a new email worm. It spread via an infected email attachment, lay in wait for a short time, and then surreptitiously downloaded more malicious files: keyloggers, backdoors, and spam servers.

Hyppönen called it the SoBig worm and quelled its spread quickly by instructing email providers to block all emails from the SoBig email address. But new worm variants continued to pop up throughout the year, each one more sophisticated than the last.

On August 19, after a long week dealing with Blaster and Welchia, one of Hyppönen’s researchers spotted another SoBig variant for the first time.

The team named it SoBig.F, and Hyppönen immediately saw it was leagues apart from its predecessors. It could spread so quickly as to seem unstoppable, and it was scheduled to download an unidentified program in three days’ time.

Within a few hours, Hyppönen had written and released a program to detect and remove SoBig.F from infected computers. But there were still hundreds of thousands of vulnerable users, each sending and receiving thousands of spam emails — and imminently set to experience an even worse infection.

Hyppönen and his team spent the next several days reverse engineering the worm, eventually identifying its 20 originating servers around the world. They then tried to get ISPs and governments to shut those servers down before they could begin serving the malicious download.

Ultimately, 19 of the 20 servers were shut down, and the remaining server was so bogged down with traffic that it never executed its payload. Hyppönen, having saved millions of computers from an unknown fate, was hailed as a cybersecurity hero.

Hyppönen Goes Global

Hyppönen Goes Global

Throughout the 2000s and 2010s, Hyppönen continued his work with F-Secure. But he also saw his newfound fame as an opportunity to educate the populace about cybersecurity.

Hyppönen began traveling around the world, giving presentations to militaries, industry groups, students, and the general public. These ranged from highly technical keynotes at hacker conventions to lectures at Stanford University to TED talks.

Additionally, Hyppönen began offering personal advice to governments facing cybersecurity threats in the US, Europe, and Asia.

In 2007, he was named one of PC World’s 50 Most Important People on the Web. That same year, he joined the advisory board of the International Multilateral Partnership Against Cyber Threats (IMPACT), an UN-backed cybersecurity alliance.

By 2011, Hyppönen wrote columns and articles for the New York Times, CNN, Scientific American, and other world-renowned publications. Several of them addressed the then-unknown origins of Stuxnet, the ultra-sophisticated malware that attacked Iran’s nuclear plants, with Hyppönen correctly surmising that the US government created it.

His profile grew even higher that year when he debuted his documentary, “Brain: Searching for the First PC Virus in Pakistan,” to global acclaim. The film chronicled his trip to Pakistan to meet and interview the creator of Brain, widely considered the world’s first computer virus.

Hyppönen’s Law


As the Internet of Things expanded rapidly in the 2010s, Hyppönen recognized it as a cybersecurity nightmare. Smart lightbulbs, appliances, sensors, accessories, and other gadgets were generally poorly secured, causing a huge spike in IoT malware attacks.

This prompted Hyppönen to issue a cautionary tweet in 2016: “Hyppönen’s Law: Whenever an appliance is described as being ‘smart,’ it’s vulnerable.”

His clear, succinct message — and the seriousness of its implications — again brought Hyppönen’s name to the headlines. The Law took hold so strongly that it formed the basis of Hyppönen’s 2021 book, “If It’s Smart, It’s Vulnerable.”
