Brute Force Password Attack | Repeated attempts to guess passwords to gain access. | Use strong, complex passwords. |
1. Physical Attacks
Physical attacks occur when an attacker gains direct access to an IoT device. By tampering with hardware, they can extract sensitive data or install malicious software. Protect devices in secure environments to prevent these attacks.
2. Encryption Attacks
Encryption attacks target weak or improperly implemented encryption protocols. Hackers can decrypt sensitive data being transmitted across IoT devices, leading to data breaches. Ensure robust encryption standards to mitigate this risk.
3. DoS (Denial of Service)
In a Denial of Service (DoS) attack, hackers flood an IoT device with excessive traffic, rendering it unusable. This attack can disrupt services or make critical devices unresponsive. Network security measures can help defend against DoS.
4. Firmware Hijacking
Firmware hijacking occurs when attackers infiltrate IoT firmware, manipulating it to control device behavior. This can compromise an entire system. Regular updates and firmware integrity checks are essential safeguards.
5. Botnets
Botnets are networks of compromised IoT devices controlled by hackers. They are often used for large-scale attacks, such as Distributed Denial of Service (DDoS). Securing IoT devices with strong authentication reduces the risk of botnets.
6. Man-in-the-Middle
In this attack, hackers intercept communication between IoT devices and networks. By modifying or eavesdropping on the data, they gain access to sensitive information. Use encryption and authentication to secure data transmission.
7. Ransomware
Ransomware targets IoT devices by encrypting files or locking users out until a ransom is paid. It can cause operational shutdowns. Backups and regular security scans are key to avoiding ransom demands.
8. Eavesdropping
Eavesdropping attacks happen when hackers secretly listen to communications between IoT devices. By intercepting this data, they can steal personal or sensitive information. Encrypting communications is a simple yet effective defense.
9. Privilege Escalation
