![]() ![]() Further manual dynamic analysis can be done under Qemu virtual machine, but that is out of the topic subject of this blog post. Virus total results of the captured malware sample: and it is yet another clone of Mirai botnet strain. C2 server details of botnet that dropped sample Shell interaction after successful login attempt with default creds This is solid proof I wanted to suggest that the internet is a wild jungle and this is how often you get attacked. More tweaks may require to capture more samples. I was able to capture one sample, although note that this not an effective honeypot setup on default settings. You can test your connection over telnet port and see if data is being logged or not. You can visit honeypot UI on and admin credentials will be in config.yaml After that run create_docker.sh it will setup everything for you. Let’s get hacked on default creds with honeypotĬlone GitHub repository and setup docker on your cloud instance. For this let’s use any cloud provider so we can have public IP, I used Linode. Let’s do a small experiment by quickly spinning up the telnet IoT honeypot to see how quickly we can get compromised. ![]() Also not to forget the recent Silex botnet attack which permanently damaged/bricked IoT devices with default credentials, as part of a joke from a 14-year-old threat actor. It seems due to some awareness about this situation over the years numbers have reduced. And as a troll, it changed the hostname of these devices to HACKED-ROUTER-HELP-SOS-DEFAULT-PASSWORD as a warning to the device owner. This is an old report I had created almost 2 years ago, basically, a botnet was targeting Ubiquiti and MikroTik routers via default credentials. I have a habit of creating shodan reports to keep track of botnet infections in popular devices. It is a popular search engine for IoT devices both white hat and black hat hackers use it to understand security trends among exposed devices and even collect IP addresses having specific types of vulnerabilities. Let’s have look at the Shodan case study. And that is how most probably the creator of Mirai botnet created a password list for most common guessable and default creds to conduct brute force attacks on open telnet ports on the entire internet. ![]() Let’s say if you configuring an IP camera in your home and the default username: admin and password: admin for device management interface over the network.Īnd this information can be easily found by visiting the user manual of the product available online. Many times when you configure an IoT device, in the initial stages of setup you will be given a default setup of credentials to work with. Yes, all of the IoT botnet malware gains access to IoT devices and network switches via password brute force attacks. When it comes to finding scenarios of exploitation of this OWASP IoT vulnerability top 10 most common thing that comes into my mind is botnets. And today we will explore the oldest and most common mistake which is a weak password configuration in these smart internet-connected devices. In the last blog we had explored OWASP IoT Top 10 vulnerabilities overview, now we will explore the impact of each of these OWASP vulnerabilities on IoT technologies and product development.
