![]() ![]() IoT device ransomware attacks typically don’t encrypt data for a ransom. RansomwareĮven though most IoT devices don’t hold sensitive information, ransomware can still affect them. They might even change the information transferred between IoT devices and servers to gain access to private data or the system. They can get private, sensitive data this way. Man-in-the-Middle (MITM) AttacksĬybercriminals can take advantage of gaps in IoT devices’ network communication protocols. Many of these devices had weak passwords and outdated software, making it easy for hackers to get access and take over. The malware that infected the IoT devices gave rise to the botnet’s name, Mirai. This affected well-known media outlets like Reddit, Netflix, Twitter, and CNN. Huge portions of the Internet were down due to this one attack. The Mirai botnet attack occurred in 2017, where cybercriminals used a massive IoT botnet to interfere with Dyn, a DNS service provider. It resembles an army of compromised devices that collaborate to attack other networked systems.Īttackers can direct these infected devices to tasks like overwhelming a network with data or sending spam using a botnet. However, if they take over many IoT devices, they can build a “botnet.” Botnet Attacksīecause Internet of Things devices lack the robust security measures of more advanced computers, they are vulnerable to malware attacks.Ī single IoT device infected by an attacker doesn’t cause much damage. Before we show you how to protect IoT devices from hackers, here are some of the common IoT security threats you should know: 1.
