Mirai Botnet is a notorious example of an IoT attack that targeted devices like DVRs, IP cameras, and routers. The attack involved compromising these devices using default or easily guessable credentials, turning them into “bots” that could be controlled remotely. These bots were then used to launch Distributed Denial of Service (DDoS) attacks, overwhelming websites and online services with traffic.

Why was it successful?

• Weak Default Credentials: Many IoT devices come with weak or default passwords that are easily guessable, making them vulnerable to brute-force attacks.
• Lack of Security Updates: IoT manufacturers often neglect to provide regular security updates, leaving devices exposed to known vulnerabilities.
• Large Attack Surface: The sheer number of IoT devices connected to the internet creates a massive attack surface for malicious actors.

Red Flags to Look Out For: When considering using IoT-enabled devices, be aware of these red flags:

• Lack of Security Features: Check if the device has features like strong password requirements, encryption, and regular security updates.
• Default Credentials: Avoid using default passwords and change them to something strong and unique.
• Unknown Manufacturers: Be cautious of devices from lesser-known manufacturers, as they may have lower security standards.
• Limited Support: Ensure that the manufacturer provides ongoing support and security updates for the device.

By being aware of these red flags and taking steps to protect your IoT devices, you can significantly reduce the risk of falling victim to attacks like Mirai Botnet.
