New Sophisticated Botnets Discovered

New cyber-storm clouds are gathering. Check Point Researchers have discovered of a brand new Botnet evolving and recruiting IoT devices at a far greater pace and with more potential damage than the Mirai botnet of 2016.
While some technical aspects lead us to suspect a possible connection to Mirai, this is an entirely new and far more sophisticated campaign that is rapidly spreading worldwide. It is too early to guess the intentions of the threat actors behind it, but with previous Botnet DDoS attacks essentially taking down the Internet, it is vital that organizations make proper preparations and defense mechanisms are put in place before an attack strikes.
Unlike the aforementioned IoT botnets, this one tries to be more stealthy and persistent once the device is compromised, and it does not (yet) do the usual stuff a botnet does like DDOS, attacking all the devices connected to the internet, or, of course, mining cryptocurrencies.
The infection chain starts with a telnet attack on the weak credentials of targeted devices followed by execution of an initial shell script. This script looks quite different from typical scripts that IoT malware uses in that it is far more sophisticated.
By looking into the logs, it seems that someone actually ran DirBuster-1.0-RC1, trying to figure out what is going on. Brute force DirBuster is used to guess directories/filenames on the web server and generates a large number of requests. It is quite unfortunate if this scan originated from a researcher as there are more elegant approaches in the case of a sophisticated malware like Torii.
Threats are becoming more sophisticated, incorporating emerging technologies, advanced cryptography, and resilient infrastructure to resist surveillance and disruption. Modifications to banking trojans support stealing bank credentials and website cookies to impersonate victims, searching hard disks for specific files, granting threat actors remote access to a computer, and allowing threat actors to exfiltrate stolen information or download additional malware. Cybercriminals are also expanding beyond traditional banking botnets to evolve new attack vectors. CTU researchers observed an increase in persistent attacks targeting specific organizations to compromise financial accounts, illustrating use of a delivery method that was previously used only in advanced persistent threat (APT) attacks. With banks continuously moving to the mobile platform for payment and banking applications, cybercriminals' interest in targeting mobile banking services has increased. Attacks on mobile banking platforms, as well as advancements in bypassing advanced authentication mechanisms like two-factor authentication (2FA) and transaction authentication numbers (TANs), evolved in 2015.
While most banking botnets that were active in 2014 continued their operations in 2015, Shifu, Corebot, and Reactorbot emerged as new additions. Increased activity from Qadars, Tinba, Gozi ISFB, and Gozi Neverquest reflected a consistent market for banking fraud, and the reemergence of Ramnit and Bugat v5 after takedowns showed the cybercriminals' resilience. A search for other revenue streams led to a steady shift in 2015 from botnet-driven infections to ransomware. Ransomware provides threat actors with a straightforward and direct revenue stream and does not require infrastructure maintenance.
The botnet-as-a-service model has grown increasingly popular. Threat actors rent subsets of their botnets for malicious activities such as distributed denial of service (DDoS) attacks, click fraud, cryptocurrency mining, and targeted attacks. Mobile botnets are also used for DDoS attacks, click fraud, and impersonation attacks. However, there is still a strong demand for the standalone botnet-as-a-kit service because it allows threat actors to maintain full control of the malware, infrastructure, and operatio
