Strengthening cybersecurity with the help of ethical hackers

At an exhibition hall in Helsinki, a hacker who calls himself ‘The Mask Guy’ sits down at his PC alongside a group of fellow computer experts, who all start feverishly hacking away at a KONE test monitoring system. Their goal is very clear – to beat KONE’s defenses and bring that system to its knees.

These talented and often anonymous computer whizzes come from different walks of life, but they share a common passion – to find ways to break into connected devices, services, and embedded systems, no matter how secure their administrators may believe they are.

But what is different about this crowd is that they are known in the cyber community as ‘white hat’ or friendly hackers – ethically-driven computer pros. Their motivation, be it for pleasure, profit, or prestige, is to probe for weaknesses in connected systems and thereafter collaborate with their owners to help make them more secure to keep out the bad guys, the ‘black hats’.

It’s for this reason that corporations, cybersecurity professionals, and ethical hackers have gathered at the annual Disobey Nordic Security Event in Helsinki to share expertise and take part in challenges. At the ‘Capture the Flag (CTF)’ competition, co-sponsored by KONE, white-hat hacker teams will race to find a vulnerability in a KONE test monitoring system and exploit it, allowing the company to gain ever-deeper insights and stay one step ahead of attackers.

For the hackers, events like Disobey are not only a chance “to raise awareness of security,” says ‘The Mask Guy’, but also to socialize with and work alongside other “ethically driven, positive and collaborative people”.

Ethical hacking is a necessity in today's world as cyberattacks led by hostile or “black hat” hackers have rocketed.

Research by Check Point Software Technologies tells us that between 2020 and 2021, cyberattacks on corporations increased by 50 percent. What’s more, the cost of cyberattacks is growing – for companies and ultimately for their customers, with the average cost of a data breach estimated at $4.35 million in 2022.

As products and services become increasingly connected, customers need more than ever before the peace of mind that companies are taking all possible measures to protect themselves and their customers against hostile actors.

“Unethical hackers have a number of vectors in which to attack any company – especially those that do not invest and continuously improve their security practices,” explains Laura Kankaala, Threat Intelligence Lead at Finland-based F-Secure, a paragon within the cybersecurity industry and periodic consultant to KONE.

“They will come at you through a vulnerable web application, a misconfigured cloud service, a poorly protected identity, untrained staff who fall victim to e-mail phishing attacks, or in cases where the company has not enforced basic security settings such as multi-factor authentication across a company’s IT services.”

Kankaala, an experienced ethical hacker in her own right, likens successful cybersecurity to a puzzle comprised of many pieces. These traditionally include a company’s own IT pros, top-notch security consultants, proven internal policies and training. But more recently, warming-up to friendly hackers who will play on your team has become an invaluable tool in the box.

“Even then it’s essential to understand that keeping the unethical and criminal hackers at bay results from a comprehensive cybersecurity plan, and still the plan itself is not a destination but rather a continuous journey,” adds Kankaala.

Back at the Disobey CTF challenge, ethical hacker ‘The Mask Guy’, – who uses a pseudonym due to his day job as an Internet of Things expert at a large cybersecurity firm – conspires with his team to employ any and every trick in their book to hack into the KONE demo system and seize control of it first in order to win the competition.

Looking over these hackers’ shoulders is Dominik Koehler, Senior Application Security Expert at KONE, who smiles to himself at the clever coding and impressive problem-solving going on.

“KONE has always taken cybersecurity and the threat that hackers pose very seriously,” Koehler says. “We want to continuously improve our products and one of the ways we can do this in the security area, is to directly engage with the white hat community through our bug bounty program. To build bridges between the white hat community and our internal stakeholders is a very good way to establish closer collaboration.”

“The Disobey event provides a perfect venue to build those bridges.”

Such bug bounty programs have not only become commonplace among organizations in the private and public sector in recent years but are now considered an emerging best practice to ensuring robust cybersecurity. Indeed, formalized training and certifications are now being offered such as the EC-Council’s Certified Ethical Hacker program as well as a three-course certificate program at the University of Washington in the US.

But Koehler makes clear that there is no substitute to having your own team of crack cyber specialists inside the company, too.

“Historically, a traditional organization specializing in systems such as KONE might not have been the obvious choice for cybersecurity professionals seeking employment. However, this perception is shifting. With our heightened online presence across products and services, ensuring robust cybersecurity has escalated to a critical priority. This drives our commitment to attract exceptional cyber expertise in the field.”

KONE’s commitment to cybersecurity was recognized in 2023 when it became the first in the industry to gain the IEC 62443 cybersecurity certification for its DX class elevators, and ISO 27001 certification for its digital services, including KONE 24/7 Connected Services.

So, the question remains … did ‘The Mask Guy’ and his team of white hats succeed, or did the KONE demo system’s cyber fortress hold?

“Yeah … we captured the flag,” deadpans ‘The Mask Guy’. “It wasn’t easy, but our team did find a way to get root access to the system.”

And with it, first-place winner of the 2023 Disobey CTF competition.

For KONE, the route that the hackers found into the system provided valuable cybersecurity insights that can be made use of in future.

“It was a great learning experience for us,” Koehler points out, “and our event demo monitoring system’s cyber resilience held up well - for most of the time.”

“For KONE, the experiences we shared at Disobey helped to engage directly with the white hat hacker community and serve as a framework for us to collaborate more closely going forward to build better cybersecurity in our products and services for our customers,” adds Koehler.
