VirTool:Win32/Vbinder - Windows Defender Threat Analysis

$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: VirTool:Win32/Vbinder
Classification:
Type:VirTool
Platform:Win32
Family:Vbinder
Detection Type:Concrete
Known malware family with identified signatures
Confidence:Very High
False-Positive Risk:Low

Concrete signature match: Virus Tool - Tool used to create or modify malware for 32-bit Windows platform, family Vbinder

Summary:

VirTool:Win32/Vbinder is a malicious utility designed to bundle multiple files, often a legitimate application with a hidden payload, into a single executable. It utilizes Visual Basic, drops temporary files, and abuses legitimate Windows functions and LOLBINs (e.g., ShellExecute, mshta, regsvr32, rundll32, PowerShell) for execution, persistence (scheduled tasks, BITS jobs), and potentially evasion through API hooking and data encoding.

Severity:
Critical
VDM Static Detection:

Remediation Steps:
Isolate the infected system immediately. Perform a full system scan with updated antivirus software to remove the binder and any dropped malicious components. Manually inspect for persistence mechanisms (e.g., scheduled tasks, registry run keys, BITS jobs) and review system logs for suspicious activity, particularly execution of LOLBINs like PowerShell, mshta, or rundll32, to identify and mitigate any secondary infections or lateral movement.
