FBI in Smart Device Security Warning: The FBI has been forced to post a public service announcement about the danger of unprotected IoT devices that might harm us.
In other sign of the growing threat that were posted by compromised smart devices, the update was claimed just last week that the attackers were using them as their proxies to maintain their online anonymity and obfuscate the network traffic.
Which enables them to click fraud, trade illegal goods, send spam emails, and mask their internet browsing. IoT devices can also be conscripted into botnets which will be rented out, sold or used directly for credential stuffing and other attacks, the alert claimed.
The FBI in Smart Device Security warned the individuals about several warnings signs to users’ smart devices that may have been taken over: this results in very huge internet usage, high ISP bills, slow or inoperable devices, unusual outgoing DNS queries and traffic and slow internet connections.
Everything from your routers and NAS devices to DVRs, Raspberry Pis, and even smart garage doors openers could be at risk.
“Devices in developed nations are particularly attractive targets because they allow access to many business websites that block traffic from suspicious or foreign IP addresses. Cyber actors use the compromised device’s IP address to engage in intrusion activities, making it difficult to filter the regular traffic from malicious traffic,” the notice continued.
“Cyber actors typically compromised devices with weak authentication, unpatched firmware or other software vulnerabilities, or employ brute force attacks on devices with default username and passwords.”
The risk have occurred from insecure consumer IoT devices which have been long been known — ever since the Mirai botnet DDoS-ed string of big-name sites back in 2016. As with an estimated 20.4 billion connected ‘things’ in operation by 2020, the threat continues to rise.
That‘s why the British Standard Institution Launched a kitemark initiative earlier this year, in a bid to improve the baseline security of products which helped the buyers to better the indentify the smart devices so that they can trust to be reliable and secure.
The FBI warned the users to reboot the devices regularly, and change the default log-ins, usa AV, ensure they are up to date with patches, and isolate IoT devices from other network connections.
