The risks of unsupported IoT tech

The article discusses the significant cybersecurity risks posed by outdated Internet of Things (IoT) devices that have reached the end of their product lifecycle, known as end-of-life (EOL). Once devices are deemed EOL, manufacturers halt their support, including software updates and security patches, exposing users to vulnerabilities that cybercriminals can exploit. This situation transforms obsolete devices into attractive targets for hackers who can gain control over them and utilize them for various malicious activities, such as spying or integrating them into large networks of compromised devices, known as botnets.

Estimates suggest there are approximately 17 billion IoT devices worldwide, with a potential third becoming obsolete within five years. This could result in about 5.6 billion devices becoming increasingly vulnerable as manufacturers cease support. Such devices can be easily hijacked to form botnets, making it possible for hackers to conduct significant cyberattacks, including data theft and the distribution of malware.

A notable example is the Mozi botnet, which compromised hundreds of thousands of IoT devices and used them for a multitude of harmful purposes. Vulnerable devices, including smart cameras, can be exploited for surveillance, with attackers gaining remote access without prior knowledge of the device’s credentials. This underscores that the lack of manufacturer action on older devices leaves users at heightened risk.

Despite the dangers associated with EOL devices, many users hesitate to upgrade, opting instead to continue using outdated products out of a lack of awareness or financial constraints. However, this behavior can result in severe security vulnerabilities. As a response, some users are repurposing old devices for non-internet-connected uses, such as utilizing an old tablet as a smart home controller. While this can mitigate risks, security remains a concern, especially if these devices are ever connected to the internet again.

The challenge posed by outdated devices extends beyond their immediate use; even discarded devices can harbor sensitive personal information that could be harvested by malicious actors. Hence, securely disposing of old electronics is critical, not only from a security standpoint but also for environmental reasons.

Botnets, bolstered by outdated devices, can facilitate distributed denial-of-service (DDoS) attacks and other nefarious activities. Efforts to dismantle botnets typically require coordinated action from law enforcement and cybersecurity professionals. However, the resilience of such networks means they can reestablish themselves after being disrupted, leading to ongoing security challenges.

The broader implications of IoT devices in the realm of cybersecurity warrant careful consideration. As malicious actors devise more sophisticated strategies to exploit vulnerable devices, maintaining security and privacy becomes paramount. The article emphasizes the importance of keeping devices updated and replacing those that cannot be secured.

In conclusion, the growing trend of outdated IoT devices poses serious cybersecurity risks. To safeguard against potential cyber harm, users should be proactive about device maintenance and secure disposal, recognizing the implications of using unsupported technology in an increasingly connected world.
