We analyzed another Mirai variant called “Miori,” which is being spread through a Remote Code Execution (RCE) vulnerability in the PHP framework, ThinkPHP. Aside from Miori, several known Mirai variants like IZ1H9 and APEP were also spotted using the same RCE exploit for their arrival method. The aforementioned variants all use factory default credentials via Telnet to brute force their way in and spread to other devices.

Smart Protection Network (SPN) data and observations from Managed Detection and Response (MDR) for the North American region show the persistence of older threats and tactics: delivery methods such as spam emails are still going strong, while ransomware attacks have seen a renewed vigor alongside newer threats such as cryptocurrency mining malware in the third quarter of 2018.
However, the prevalence of these older threats should not be misconstrued as a sign that threat actors are resting on their laurels. In fact, it should be taken as proof that they are constantly improving proven tools and techniques to get ahead in the never-ending cat-and-mouse game between cybercriminals and security providers.

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.
