The group has altered from its earlier.NET malware to really brand-new variations composed in C++. In this new variation, there are 2 clusters of variants, named:-.
Off of.NET, Onto C++.
There are some Kevin samples that were being shipped with an interaction channel that conveys information with the C&C as part of HTTP traffic. These variants are expected to accomplish a command file from rejoinders to HTTP GET demands that are provided to the server.
Since this trojan doesnt have any particular approach to communicate to a command-and-control (C2) server, so, it may be an extremely new method to do proxy traffic between internal network clusters..
Kevin variant, DNS protocol, and HTTP protocol.
The Kevin variant appears to explain a brand-new branch of development that is revealed in the groups arsenal. The primary motive of this variation is to facilitate an interaction channel that usually moves arbitrary commands that are to be executed by the implant.
Apart from the Kevin variation, the James variation is based upon a PDB course that is practiced in its samples. This variant accepts only one conflict in its command line and all of its samples are 32-bit ones.

Rotating on the C2 server utilized in the PowerShell scripts drove them to numerous unique implants that are composed in C++. And all these implants were utilized by the hazard actors simultaneously toward targets in Tunisia..
The security researchers of Kaspersky Lab has detected some finding and reported it at the VirusBulletin VB2021 conference earlier this month, where they have linked the attacks to a group tracked as Lyceum.
The hacking group Lyceum is starting the big attack and is still active, thats why the professionals highly suggested the companies to stay alert and always have regular examinations that will help them to discover this type of attack.
The DNS protocol is normally utilized to talk over DNS constructs domains that are published as part of either an A record or TXT type questions. And it likewise sends out data to the server by placing it within the domain.
These threat stars are popular for striking business that deal with energy and telecommunications sectors throughout the Middle East in early 2018.
Moreover, all its questions reading the DNS are performed by utilizing the DnsQuery_A() API rather than executing a subprocess of the nslookup energy.
These were the names that are present on the systems and were used to compile the malware. The brand-new DanBot versions, support comparable customized C2 protocols tunneled over DNS or HTTP, much like the old one.
The variants that have been found till now share an equivalent operation model and the communication channel is used to drop files in addition to commands to execute or directions to transform the malwares configuration..
The Lyceum danger group (aka Hexane) once again started an attack, however this time they have a weird variation of a remote-access trojan (RAT). This time they are using the PowerShell scripts and.NET RAT to deploy keylogger on the targeted Windows system and steal credentials.
The more the security specialists examined the attack, they discovered many crucial information about the functions that distinguish the attack from the other.
