Irish households are facing a growing cybersecurity threat emanating from seemingly innocuous smart home devices, including low-cost Android TV boxes often referred to as “dodgy boxes.” A recent surge in cyberattacks, including what is believed to be the largest Distributed Denial of Service (DDoS) attack ever recorded, has highlighted the vulnerability of these devices and the potential for widespread compromise.
Security researchers at Grant Thornton Ireland have warned that millions of these poorly secured devices globally have been infected and are now under the remote control of cybercriminals. The attacks are largely attributed to a botnet known as Kimwolf, comprised primarily of compromised Android-enabled televisions and streaming devices. The scale of the threat extends beyond entertainment systems, encompassing a broader range of low-cost Internet of Things (IoT) gadgets increasingly prevalent in Irish homes.
The DDoS attack, which occurred late last year and lasted just 34 seconds, targeted multiple platforms and demonstrated the disruptive potential of a network of infected devices. While the immediate impact was relatively short-lived, the incident serves as a stark warning about the future capabilities of attackers leveraging compromised home devices. Some estimates suggest as many as 400,000 Irish households may be using these vulnerable “dodgy boxes.”
The risk isn’t simply about disruption of service. Once attackers gain access to a home network through a compromised device, they can exploit that access in multiple ways. Howard Shortt, Cybersecurity Partner at Grant Thornton Ireland, explained that attackers can use compromised devices as part of a botnet to launch further attacks, or quietly profile household activity to facilitate more targeted phishing scams. Many people don’t realise that a low-cost Android TV box in their sitting room or a cheap smart lightbulb can be compromised in seconds,
Shortt stated.
The profiling process involves observing network traffic patterns to build a detailed understanding of a household’s habits and preferences. This information is then used to craft highly believable phishing messages. For example, an attacker might pose as a streaming provider, prompting a user to review a show they recently watched – a tactic designed to bypass typical security skepticism. This level of personalization significantly increases the likelihood of a successful phishing attack.
The vulnerabilities exploited by cybercriminals typically involve default passwords, outdated software, and unpatched security flaws in internet-connected devices. The ease with which these devices can be compromised is particularly concerning, given the often-limited technical expertise of the average consumer. The Irish Examiner reported on , that the public is being advised to take basic security precautions.
Grant Thornton Ireland recommends several steps to mitigate the risk. These include changing default passwords on all smart devices and routers, ensuring software is up-to-date, and purchasing devices only from reputable brands and legitimate vendors. This last point is crucial, as lower-cost devices are often manufactured with minimal security considerations.
The issue extends beyond individual consumer risk. The compromised devices can be leveraged to launch attacks against businesses and critical infrastructure, highlighting the interconnectedness of cybersecurity threats. The Irish Times noted that tapping into unsecured devices allows hackers to potentially spy on occupants and expose them to more targeted scams.
The warning comes at a time when smart home adoption is rapidly increasing, with consumers embracing a wider range of connected devices for convenience and automation. While these devices offer numerous benefits, they also introduce new attack vectors that require careful consideration. Newstalk highlighted the increasing risk, stating that dodgy boxes are even dodgier than you might think!

The recent cyberattack underscores the need for greater awareness among consumers and manufacturers alike. Consumers must prioritize security when purchasing and configuring smart home devices, while manufacturers have a responsibility to build security into their products from the outset. The potential consequences of inaction – ranging from financial loss to widespread disruption – are simply too significant to ignore.
The incident also highlights a shift in the cybersecurity landscape, with individuals increasingly becoming targets. Traditionally, cybersecurity efforts have focused on protecting workplace technology, but the proliferation of connected devices in the home has blurred the lines and expanded the attack surface. As Shortt noted, cyber threats are no longer limited to workplace equipment.
The Independent.ie reported that the attack by the Kimwolf botnet occurred in . The professional services firm has warned that everyday home technology is susceptible to being compromised by sophisticated hacking efforts. The warning from Grant Thornton and other security experts serves as a critical reminder that even seemingly harmless devices can pose a significant cybersecurity risk.
