For example, CISOs could limit access to IoT devices to only systems within the corporate network on a specific IP address and block everything going out except that communication. 192.168.10.18 - Vunerable to SSH Brute Force. security threats and potential attacks [2,3]. Like Mirai, this new botnet targets home routers like GPON and LinkSys via Remote Code Execution/Command Injection vulnerabilities. Take, for example, the Mirai botnet, which infected millions of consumer devices such as IP cameras and home routers to launch a distributed denial of service attack that was able to cripple major websites such as Netflix, Twitter, and Reddit. However, when botnets are misused for malicious purposes, they can be very dangerous. In their report, the team states that DDoS attacks from a botnet with 30,000 infected devices could generate around $26,000 a month. It will always be in a malicious hacker’s interest that the victim isn’t aware of the infection so that the botnet stays available for the longest time possible. Geographical distribution of detection — Statistical data of related malware samples from around the world. Furthermore, it had been proved that network devices were also affected.

These are some popular botnets that are used for perpetrators more frequently. The proliferation of IoT devices which can be more easily compromised than desktop computers has led to an increase in the occurrence of IoT based botnet attacks. In order to mitigate this new threat there is a need to develop new methods for detecting attacks launched from compromised IoT devices and differentiate between hour and millisecond long IoTbased attacks. coordinated together to perform of hijacked devices (robots) access to.
