Manufacturing Companies Targeted with New Lumma and Amadey Campaign

The manufacturing industry has long been a target of cybercriminals. While data encryption has been a prevalent tactic in recent years, threat actors are now increasingly focusing on stealing sensitive information and gaining control over critical infrastructure.

One of the latest campaigns on record involves the use of Lumma and Amadey malware.

Campaign Uses Fake LogicalDOC URLs

This campaign heavily leverages Living Off the Land (LOLBAS) techniques to deliver malware as part of its operations.

Threat actors distribute phishing emails with URLs leading targets to download LNK files disguised as PDFs. These files are accessed via a domain name masquerading as one belonging to LogicalDOC, a service for managing documentation widely utilized in the manufacturing industry.

Attack Involves Scripts to Aid Infection

The malicious LNK file, once activated, initiates PowerShell via an ssh.exe command. Following a chain of scripts, a CPL file is downloaded from berb[.]fitnessclub-filmfanatics[.]com as a ZIP archive.

The malware utilizes both PowerShell and Windows Management Instrumentation (WMI) commands to collect detailed information about the victim’s system. This includes:

Data such as language settings
Antivirus software
Operating system versions
Hardware specifications

This reconnaissance allows attackers to tailor subsequent attacks and enhances their credibility when sending follow-up malicious emails within the targeted organization.

DLL Sideloading Ensures Evasion

Attackers run malicious code in memory without leaving traces and abuse standard Windows tools to blend in with regular system activities. The downloaded ZIP file contains several malicious files used to carry out DLL sideloading.

Key Objective

The primary purpose of this attack is to:

Steal important information with Lumma Stealer
Maintain control over the infected systems with Amadey Bot

Aattackers gain the ability to continuously monitor and manipulate their targets, which poses a significant threat to manufacturing businesses.

Why Businesses Need to Pay Attention

For manufacturing companies, the consequences of such attacks can be severe and include:

Theft of intellectual property
Disruption of operations
Financial losses and compliance violations

Understanding and preparing for these threats is crucial for protecting valuable assets, maintaining operational integrity, and ensuring the safety of employees and customers.

Analysis of the Attack with ANY.RUN Sandbox

To proactively identify malicious files belonging to this and other malware attacks, analyze them in the safe environment of ANY.RUN’s Interactive Sandbox that offers:

Real-time Insights: In-depth view of malicious activities as they occur.
Interactivity: Test threat responses in a live system.
Comprehensive Reporting: Detailed reports on IOCs, malware families, and more.

*Analysis of a malicious LNK file inside ANY.RUN’s Sandbox*

By uploading a malicious LNK file to the sandbox and executing it we can observe how the entire chain of infection plays out.

View analysis session

*ANY.RUN detects activities related to malicious and suspicious process*

First, the .lnk file initiates SSH, which starts PowerShell.

*Mshta is utilized to download a payload from remote server*

PowerShell then launches Mshta with the AES-encrypted first-stage payload that it decrypts and executes.

*Attack uses Emmenhtal loader to faciliate infection*

PowerShell executes an AES-encrypted command to decrypt and run Emmenhtal.

*Suricata IDS is used in ANY.RUN to identify Amadey-related traffic*

Emmental leads to system infections with Lumma and Amadey as a result.
