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
Already, current cellular network technologies such as 3G and 4G allow fast wireless communication. But the next evolution, 5G, is set to afford even faster connections along with greater reliability. Touted as the next generation of mobile internet connectivity, 5G will offer speeds of the order of several gigabits per second (Gbps), with average download rates expected to be about 1 Gbps. While its improvements over previous generations will doubtless be most apparent in smartphones and other widely used internet-enabled mobile devices, 5G is also likely to benefit the internet of things (IoT) since it can very well provide the infrastructure the IoT needs to carry and transfer massive amounts of data.Read More
Using our IoT Smart Checker, a tool that scans networks for potential security risks, we looked into home and other small network environments and the vulnerabilities that connected devices usually encounter. Our findings homed in on known vulnerabilities, IoT botnets with top vulnerability detections, and devices that are affected.
From April 1 to May 15, we observed that 30 percent of home networks had at least one vulnerability detection. A detection would mean that we found at least one connected device being accessed through a vulnerability in the network. Our scanning covered different operating systems (OSs), including Linux, Mac, Windows, Android, iOS, and other software development kit (SDK) platforms.
We recently found similar Mirai-like scanning activity from Mexico with some being done via the exploitation of CVE-2018-10561 and CVE-2018-10562, two vulnerabilities that are specific to Gigabit Passive Optical Network (GPON)-based home routers.Read More
Crime follows the money, as the saying goes, and once again, cybercriminals have acted accordingly. The underground is flooded with so many offerings of cryptocurrency malware that it must be hard for the criminals themselves to determine which is best. This kind of malware, also known as cryptomalware, has a clear goal, which is to make money out of cryptocurrency transactions. This can be achieved through two different methods: stealing cryptocurrency and mining cryptocurrency on victims’ devices surreptitiously (without the victims noticing), a process also known as cryptojacking. In this post, we discuss how these two methods work, and see whether devices connected to the internet of things (IoT), which are relatively underpowered, are being targeted.Read More
