The provided source data contains no information about free samples, promotional offers, no-cost product trials, brand freebies, or mail-in sample programs. Instead, the data consists of technical analysis reports detailing malicious software behavior, network indicators, and registry modifications. These reports reference specific executable files, registry keys, and external URLs associated with security threats. The analysis indicates that the software in question engages in activities such as modifying Windows services, altering software policy settings, and communicating with domains flagged as malicious by reputation engines. There is no mention of legitimate consumer offers, brand promotions, or sample distribution programs in the provided context.
Malicious Software Behavior and Registry Modifications
Analysis of the provided data reveals specific behaviors associated with the executable wscript.exe. This file is observed creating and modifying critical Windows registry keys, which is a common tactic used by malware to establish persistence or alter system configurations.
Registry Access and Modifications
The data details extensive registry access by wscript.exe, targeting keys related to system services and certificate policies. These actions are classified under specific MITRE ATT&CK techniques.
- System Service Modifications: The executable modifies the
HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP\PARAMETERSregistry key. This activity is associated with MITRE ATT&CK technique T1047 (Windows Service) and T1112 (Modify Registry). Modifying these keys can allow an attacker to manipulate network settings or ensure the malware runs automatically upon system boot. - Software Policy Settings: The executable creates multiple keys under
HKCU\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATESandHKLM\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES. These keys relate to Certificate Authorities (CA), Certificate Revocation Lists (CRLs), and Trust Lists (CTLS). Modifying these policies can potentially allow an attacker to bypass security warnings, intercept encrypted traffic (Man-in-the-Middle attacks), or trust malicious certificates. The specific paths include:HKCU\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CAHKCU\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CA\CERTIFICATESHKCU\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CA\CRLSHKCU\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CA\CTLSHKLM\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CAHKLM\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CA\CERTIFICATESHKLM\SOFTWARE\POLICIES\MICROSOFT\SYSTEMCERTIFICATES\CA\CRLS
These modifications suggest an intent to compromise the integrity of the system's trust mechanisms and ensure the software remains active.
Network Indicators and External Systems
The source data includes a list of URLs and IP addresses identified as malicious by reputation engines. These artifacts are often used by malware for Command and Control (C2) communications, data exfiltration, or downloading additional payloads.
Malicious Domains
The analysis reports that several domains were flagged by reputation engines. The detection rates vary, but the presence of these domains indicates a potential threat.
- kitaair.com: Flagged by 5 out of 76 engines (6% detection rate) and 4 out of 77 engines (5% detection rate).
- a.8xcornwall.com: Flagged by 2 out of 76 engines (2% detection rate).
- gdpronline.sk: Flagged by 2 out of 77 engines (2% detection rate).
- hotdsk.com: Flagged by 7 out of 77 engines (9% detection rate).
The data indicates that these domains are associated with external systems identified as malicious. The specific context of how these domains are used is not detailed, but their inclusion in the report suggests they are contacted by the malicious software.
Potential Debugging and Analysis Evasion
One of the provided chunks mentions that the software "Possibly checks for known debuggers/analysis tools." This behavior is a characteristic of malware designed to evade detection by security researchers and automated analysis systems. If the software detects that it is running in a virtual environment or is being analyzed, it may alter its behavior or terminate to avoid revealing its malicious capabilities.
Summary of Findings
The provided source material focuses exclusively on the technical analysis of a security threat. It details the modification of Windows registry keys to manipulate system services and certificate policies. It also lists external domains that have been flagged as malicious by reputation engines. The data does not contain any information regarding consumer offers, free samples, or promotional programs.
