Common Internet of Things Security Vulnerabilities in a Connected World

By CIOReview | Tuesday, May 28, 2019

FREMONT, CA: In an era where advanced technologies like internet, hotspot, and Internet of Things (IoT) has penetrated every sphere of life, security is getting compromised. Despite the several advantages that smart technologies and IoT have offered, there remain loopholes which result in a possible cyber attack resulting in enormous damage to property and life.  IoT security threats such as DDoS, ransomware, and social engineering can steal critical data from organizations and people. Take a look at some of the menacing IoT vulnerabilities.


It is a network that combines various systems to take control of a system and distribute malware remotely. Cyber attackers control botnets using  Command-and-Control-Servers to steal confidential data, acquire online-banking data, and execute cyber attacks like DDoS and phishing. Timely check on the network operations and data exchanges help in mitigating dangers caused by botnets.

Denial of Service

A denial-of-service (DoS) attack deliberately tries to cause a capacity overload in the target system by sending multiple requests, and attackers aim to slow down or disable service to hurt the reputation of businesses and affect their revenue. Firewalls act as a weapon against DoS.

Man in the Middle

Hacker breaches the communication channel between individual systems to intercept messages among them. Attackers can send wrong messages among them and gain control over their communication. Dynamic encryption methods help to overcome this attack.

Identity and Data Theft

Confidential information such as personal details, credit and debit card credentials, and email addresses are stolen. Hackers can attack IoT devices such as smart watches, smart meters, and smart home devices to gain additional data. Use of sophisticated monitoring systems can combat such attempts. 

Social Engineering

Social engineering manipulates people into giving up their sensitive data, including passwords and banking details. It is simpler to execute in case of IoT devices that collect volumes of personally identifiable information. Strict policy updates can prevent such information leakages.


In this attack, a hacker uses malware to encrypt data that may be required, for business operations, and the attacker will decrypt the data only after receiving a ransom.
