Cybersecurity threats are no longer confined to large corporations or critical infrastructure. New data from YouSee shows that Danish households are increasingly targeted by cybercriminals. In 2025 alone, YouSee’s internet routers blocked more than 336 million instances of harmful content across over 500,000 homes in Denmark.
The figures highlight a sharp rise in both the number and sophistication of cyberattacks, largely driven by the growing use of advanced artificial intelligence by cybercriminals.
AI Is Changing the Nature of Cybercrime
On average, YouSee routers with built-in security blocked more than 650 attack attempts per household during 2025. These attacks are not only more frequent but also increasingly personal and convincing.
According to YouSee CEO Christian Morgan, artificial intelligence now plays a central role in cybercrime. AI tools make it easier to create realistic phishing websites, emails, and messages—even for criminals who neither speak Danish nor operate from Denmark. Many of today’s attacks are highly automated, giving hackers new opportunities to tailor scams at scale.
From Digital Vandalism to Financial Crime
The motivation behind cyberattacks has also shifted in recent years. Where attacks once focused primarily on causing digital damage—such as deleting files or disabling devices—modern cybercrime is increasingly driven by financial gain.
Today, attackers typically aim to steal personal data, gain access to sensitive information, or directly extract money from victims. Artificial intelligence has made these attacks both more effective and more profitable.
Smart Homes Expand the Attack Surface
Danish homes are more connected than ever before. Smart speakers, baby monitors, door cameras, robot lawn mowers, EV chargers, and other connected devices have become part of everyday life, but they also introduce new security risks.
YouSee’s data shows that each household has an average of 12.6 devices connected to its router. Any connected device can potentially be tracked, compromised, or infected. If cybercriminals gain access to a single smart device, they may be able to move deeper into the home network, steal personal information, deploy ransomware, or use household devices as part of a botnet for DDoS attacks.
What YouSee Routers Blocked in 2025
- Tracking attempts (approximately 59%)
Blocking tracking cookies and similar technologies that collect personal data for profiling, resale, or surveillance. - Fake websites (approximately 40%)
Blocking fraudulent websites posing as trustworthy sources in an attempt to steal passwords, credit card details, or other sensitive information. - Device takeover attacks (under 1%)
Blocking attacks aimed at taking control of unsecured IoT devices such as smart doorbells or appliances, which can then be used to access other devices or participate in coordinated cyberattacks.
Built-In Protection for Everyday Use
YouSee’s internet subscriptions include routers with built-in security that automatically protect all devices connected to a household’s Wi-Fi network. Suspicious and untrustworthy websites are blocked by default as soon as the router is switched on, requiring no manual setup by users.
Practical Advice for a Safer Digital Life
Authorities recommend a number of basic precautions to improve digital safety. These include protecting personal digital identities such as MitID, using long and unique passwords for each service, thinking carefully before clicking on links, and avoiding the sharing of sensitive personal information.
Users are also advised to be cautious when using open or unsecured Wi-Fi networks and to consider additional protection, such as VPN services, when accessing important digital services.
As Danish homes continue to become more digital, the data from YouSee makes one thing clear: cyber threats are rising rapidly, and home networks have become a critical frontline in the fight against cybercrime.
