Your smart home devices may unknowingly be involved in a cybercrime network.

      Smart home devices and gadgets have become standard in numerous contemporary households. Security cameras monitor entryways, streaming devices enhance television experiences, and interconnected appliances continuously share data online. While many individuals express concern over companies gathering excessive user information, an increasing cybersecurity threat indicates consumers may face an even more significant issue.

      Security researchers caution that some internet-connected devices might harbor concealed software backdoors or critical security vulnerabilities that permit unauthorized access to home networks. In certain instances, these devices could inadvertently turn a household internet connection into a means for cybercriminals without the owner's awareness.

      How compromised smart devices are exploited

      A number of the affected devices are associated with what are referred to as residential proxy networks. These services redirect internet traffic through genuine household connections, making online activities seem as if they are coming from an average home instead of a data center, VPN service, or dubious network.

      Residential proxies have legitimate applications, such as testing websites or advertisements across different regions. The issue arises when consumers unwittingly become part of these networks.

      A recent investigation by the Wall Street Journal revealed that some digital picture frames and streaming boxes appeared to feature software that automatically linked them to residential proxy services. Security experts mentioned in the report suggest that certain manufacturers may be compensated to include this software prior to the devices reaching consumers.

      Once connected, the device can inconspicuously relay internet traffic for third parties. Researchers monitoring various test devices noted activity related to gambling sites, cryptocurrency platforms, adult content, and attempts to access online accounts.

      Why this poses a concern for consumers

      Permitting outsiders to direct traffic through a household internet connection raises privacy and security issues. Criminal activities carried out via a residential proxy can seem to originate from an unsuspecting home. Security researchers indicate that these networks have been associated with fraud, ticket scalping, advertising fraud, and account misuse.

      The situation can escalate further when attackers gain direct access to vulnerable devices. Researchers have discovered indications of hackers persistently attempting to reach internet-connected gadgets, occasionally incorporating them into extensive botnets employed to execute distributed denial-of-service attacks (DDoS). Industry estimates suggest that tens of millions, and possibly hundreds of millions, of devices globally could be at risk.

      Steps to safeguard yourself

      Consumers can mitigate their risk by purchasing devices from reputable manufacturers, keeping firmware updated, and steering clear of exceptionally cheap products from unknown brands. Experts also advise avoiding unverified apps and sideloaded software, which may introduce malware into smart devices. Establishing smart home devices on a separate guest network can help limit potential damage if a device is compromised and prevent attackers from accessing phones, laptops, and other sensitive devices on the same network.
