The group has altered from its earlier.NET malware to very new variations composed in C++. In this new variant, there are two clusters of variants, called:-.
These were the names that exist on the systems and were used to put together the malware. The brand-new DanBot variations, assistance comparable custom C2 procedures tunneled over DNS or HTTP, just like the old one.
The variants that have actually been found till now share a comparable operation model and the interaction channel is utilized to drop files together with commands to carry out or instructions to change the malwares setup..
Off of.NET, Onto C++.
The Kevin alternative appears to explain a really new branch of development that is shown in the groups toolbox. The primary motive of this variation is to assist in a communication channel that usually transfers arbitrary commands that are to be carried out by the implant.
There are some Kevin samples that were being shipped with a communication channel that conveys data with the C&C as part of HTTP traffic. These variants are anticipated to achieve a command file from rejoinders to HTTP GET demands that are released to the server.
Apart from the Kevin version, the James variant is based upon a PDB path that is practiced in its samples. This alternative accepts just one conflict in its command line and all of its samples are 32-bit ones.
All its queries reading the DNS are performed by utilizing the DnsQuery_A() API rather than carrying out a subprocess of the nslookup energy.
Kevin variation, DNS protocol, and HTTP protocol.
The Lyceum hazard group (aka Hexane) once again started an attack, but this time they have an unusual 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.
Turning on the C2 server used in the PowerShell scripts drove them to different distinct implants that are written in C++. And all these implants were utilized by the threat stars simultaneously towards targets in Tunisia..

The more the security experts examined the attack, they discovered numerous essential details about the features that distinguish the attack from the other.
The security researchers of Kaspersky Lab has spotted some finding and reported it at the VirusBulletin VB2021 conference previously this month, where they have actually connected the attacks to a group tracked as Lyceum.
The hacking group Lyceum is starting the big attack and is still active, thats why the specialists strongly recommended the companies to stay alert and always have routine checkups that will assist them to find this kind of attack.
Because this trojan doesnt have any specific approach to communicate to a command-and-control (C2) server, so, it may be a brand-new way to do proxy traffic between internal network clusters..
Nevertheless, these danger actors are popular for striking business that deal with energy and telecom sectors across the Middle East in early 2018.
The DNS protocol is typically used to talk over DNS constructs domains that are released as part of either an A record or TXT type inquiries. And it also sends information to the server by placing it within the domain.
