We identified a new exploit kit we named Novidade that targets home or small office routers by changing their Domain Name System (DNS) settings via cross-site request forgery (CSRF), enabling attacks on a victim’s mobile device or desktop through web applications in which they’re authenticated with. Once the DNS setting is changed to that of a malicious server, the attacker can execute a pharming attack, redirecting the targeted website traffic from all devices connected to the same router.Read More
In our research Exposed and Vulnerable Critical Infrastructure: Water and Energy Industries, we not only found exposed industrial control system (ICS) human machine interfaces (HMIs) but also pointed out how these systems were at risk. This risk is corroborated by the active interest in water and energy ICSs shown by different kinds of cybercriminal groups.Read More
Already a vital part of the critical infrastructure of the internet, satellites are set to take on a more significant role with the emergence of 5G cellular network technology and the continuing expansion of the internet of things (IoT). While terrestrial networks handle peak load well, disaster handling and critical infrastructure scenarios are served well by satellites, which are unaffected by most ground-based events. Ensuring the security of satellites, therefore, acquires even greater importance and warrants more initiatives to that end.Read More
Even before the term IoT was coined, we had the routers at the gateway, most of the time publicly exposed on the internet. In the context of the IoT, the router is perhaps the most important device for the whole infrastructure. All traffic goes through it and it allows for the provision of many services, such as Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), content filtering, firewalls, and Voice over Internet Protocol (VoIP), to all connected devices, including computers, smartphones, and IP cameras. If an attacker is able to compromise the router, every device connected to it can be affected. And that’s what a hacking group in Brazil just did.Read More
If there is anything to be learned from the massive attacks that have been seen on connected devices, it is that the internet of things (IoT) is riddled with vulnerabilities. We have seen this time and again with how botnets are created from system weaknesses and have harnessed poor basic security to disrupt many devices and services.
In the past year, we embarked on a closer look at the security of IoT devices around the world. We chose devices that are available in different Amazon regions and are widely used in the Japan market, and tried to find out whether remote code execution (RCE) is possible. What we ended up finding out was more than that.Read More
