Windows Server Endpoint Preparation for All Supported Versions Similar methods are required for the various operating systems, and they are grouped accordingly. вЂњTheir scale and advanced design suggest that the authors are well versed in cybersecurity and that these tools might be reused in future campaigns.вЂќ And, вЂњAs most of the features are designed just to hide its presence, relay communication, and provide backdoor access, we believe that these tools are used mostly to maintain an infrastructure which serves some other, unknown, malicious purposes.Syslog - Malwarebytes Endpoint Security CEFД®ndpoint configuration changes must be implemented to facilitate installation of a Malwarebytes managed client to those endpoints. Another thing worth noting from the documentation are comments in the conclusion section stating, In regards to the Rootkits, the disclosure states that all current samples of the malware target kernel versions 2 6 32-696 el6 x86_64 and 3 10 0-229 el7 x86_64, which are older kernels from the RedHat Enterprise Linux system, however despite them being older it should be noted that a large number of production servers may still be using older systems and kernels to maximize stability, or simply as bad practice from lazier systems administrators of the вЂif itвЂ™s not broken, donвЂ™t fix itвЂ™ mindset. The documentation goes into explicit detail about how the backdoors function, what commands they utilize, and how they collect and store information necessary to function. The method in which these modified packages and applications are being distributed to victims is currently unknown.Д®SET has also disclosed that they have discovered three backdoors as part of the malware, using the Asio library from Boost.

The malware contains applications that likely have been modified at the source code level and rebuilt to perform malicious actions not existent in the original versions, such as collecting sensitive data by using modified functions such as auth_password from the sshd package. We managed to find only one active C&C server, which mostly just maintained connectivity via custom heartbeat commands and did not provide any updates on explicit requests.вЂќ We conducted several internet-wide scans that imitated initial communication of its network protocols targeting the observed non-standard ports in order to identify C&C servers and victims. None of the C&C servers used in samples uploaded to VirusTotal were active at the time of writing, indicating that they could have been disabled due to the upload. The documentation also gave some insight into the cautious measures taken by the operators of the malware, вЂњWe believe that its operators are overly cautious since almost all samples seen use different, unique C&C servers with varying non-standard ports The authors use mostly C/C++ and various third-party libraries such as Boost, Poco and Protobuf. Rootkits вЂ“ kernel-mode components that mostly hide and disguise their presence, assist with updates,.Backdoors вЂ“ user-mode components serving as the main point of communication for its operators.Trojanized applications вЂ“ otherwise legitimate binaries that are altered to load further components,Д¬ollect data, or conduct other malicious activities.The malware is able to collect credentials, and also acts as a proxy server by the use of advanced designed components that can be placed into three categories, according to the ESET release:

The malware family given the name FontOnLake, uses custom modules providing remote access to infected systems, using a rootkit to conceal the infection. Documentation released by internet security company, ESET, on October 7 th, has given details to what was lesser known malware family that emerged this past May, including details that are very relevant to the Linux world, especially those using older RedHat Enterprice Linux systems for production servers.
