Lyceum Hackers Stealing Credentials Windows By Deploy Keylogger Using PowerShell Scripts & .NET RAT

The Kevin alternative appears to describe a very new branch of advancement that is revealed in the groups toolbox. The main motive of this version is to facilitate a communication channel that normally moves arbitrary commands that are to be carried out by the implant.

The DNS procedure is usually utilized to chat over DNS constructs domains that are published as part of either an A record or TXT type questions. And it also sends out information to the server by inserting it within the domain.

Considering that this trojan doesnt have any specific approach to interact to a command-and-control (C2) server, so, it may be an extremely brand-new way to do proxy traffic in between internal network clusters..

Malware implant.

James variation.

The variants that have been discovered till now share a comparable operation model and the interaction channel is made use of to drop files together with commands to carry out or directions to change the malwares configuration..

The Lyceum threat group (aka Hexane) once again started an attack, but this time they have a strange variant of a remote-access trojan (RAT). This time they are utilizing the PowerShell scripts and.NET RAT to deploy keylogger on the targeted Windows system and take qualifications.

Kevin version, DNS protocol, and HTTP protocol.

The more the security experts examined the attack, they discovered lots of crucial information about the features that identify the attack from the other.

The hacking group Lyceum is initiating the big attack and is still active, thats why the professionals strongly advised the business to stay alert and always have routine examinations that will assist them to identify this kind of attack.

The group has changed from its earlier.NET malware to extremely new variations composed in C++. In this brand-new variation, there are 2 clusters of variants, named:-.

These were the names that are present on the systems and were utilized to put together the malware. The new DanBot variants, support comparable custom-made C2 protocols tunneled over DNS or HTTP, simply like the old one.

Off of.NET, Onto C++.

These risk actors are well-known for striking business that deal with energy and telecom sectors throughout the Middle East in early 2018.

All its questions reading the DNS are performed by using the DnsQuery_A() API rather than executing a subprocess of the nslookup utility.

Rotating on the C2 server utilized in the PowerShell scripts drove them to various unique implants that are composed in C++. And all these implants were utilized by the hazard stars simultaneously toward targets in Tunisia..

The security researchers of Kaspersky Lab has spotted some finding and reported it at the VirusBulletin VB2021 conference previously this month, where they have connected the attacks to a group tracked as Lyceum.

Apart from the Kevin variant, the James variant is based on a PDB course that is practiced in its samples. However, this alternative accepts only one dispute in its command line and all of its samples are 32-bit ones.

There are some Kevin samples that were being delivered with a communication channel that conveys information with the C&C as part of HTTP traffic. These variations are anticipated to achieve a command file from rejoinders to HTTP GET requests that are released to the server.
