Issues with passwords and authentication
Device manufacturers hardcoded default passwords to streamline end-user setup. Unfortunately, the end user usually forgets to change the password as they don’t realize the dangers of default passwords.
Insecure hardware. Something as simple as plugging in a USB driver on an IoT device can infect systems with malware.
Privacy and data leaks
IoT devices communicate with one other as well as with end users which, ironically, is one of the biggest issues as it surrenders control. While device security is important, data transmission security is also crucial.
Unpatched vulnerabilities
Frequently, we see users avoid system patches. Patches deliver security enhancements that protect networks against newly discovered vulnerabilities but when not applied, cyberattackers have a field day.
Remote employees and hybrid work
With COVID-19, many organizations now work remotely. Company-owned devices are in employees’ homes where security is not ideal and less robust than an organization’s office network.
Hybrid working models make things easier for cyberattackers as they can exploit smart devices, wearables, tablets, speakers and more.
Data interception
Hackers will intercept communication channels between systems to exfiltrate data. Many IoT devices are not encrypted and attackers can easily steal data like login credentials without needing to decrypt them.
Outdated devices
Unsupported, deprecated or outdated devices allow cyberattackers to compromise entire networks. From unreliable system customizations to the use of third-party software or hardware, attackers exploit the vulnerabilities of devices.
