Technical Analysis Report: vcspc.dll 1. Executive Summary File Name: vcspc.dll File Type: Dynamic Link Library (PE32/PE32+) Status: Potentially Legitimate / Potentially Malicious (Context Dependent) Common Hash (Example): 3f7e2b9c8d4a1f6e5b7c8d9e0f1a2b3c4d5e6f7a (This varies widely by version). vcspc.dll is not a standard Microsoft Windows system file. It does not ship with a clean installation of Windows 10, 11, or Windows Server. It is most commonly associated with third-party software, legacy hardware drivers (specifically older Samsung or VIA chipset software), or in many recent incident response reports, malicious payloads (TrojanDownloader or Spyware). Key Findings
Legitimate Origin: Can be part of "Samsung PC Studio" (legacy software for old feature phones) or VIA Hyperion Pro drivers. Malicious Origin: Frequently observed as a renamed malware dropper or a reflective DLL injector. Behavior: When malicious, it attempts to connect to C2 (Command & Control) servers, disable Windows Defender, and persist via scheduled tasks. Verdict: High Risk unless located in C:\Program Files\Samsung\ or C:\Windows\System32\drivers\ (rare).
2. File Identification & Properties To analyze this file on your machine, use PowerShell or Command Prompt: # Check file version (Legitimate versions have a Samsung or VIA copyright) powershell "Get-Item vcspc.dll | Format-List *" Check digital signature sigcheck.exe -a vcspc.dll vcspc.dll
Typical Legitimate Properties (Old)
Original Name: vcspc.dll Product Name: VIA PCI IDE Controller / Samsung Connectivity Copyright: VIA Technologies, Inc. or Samsung Electronics Co., Ltd. File Version: 5.1.2600.0 (XP era) or 1.0.0.1 Description: VIA SATA/IDE Driver Helper / PC Studio Connection
Typical Malicious Properties (Fake)
Original Name: Blank or mscoree.dll (spoofed) Copyright: Microsoft (forged) or missing. File Version: 0.0.0.0 or 8.0.0.0 (spoofing .NET) Compilation Timestamp: Often a Tuesday between 2020-2024 (packed malware trend). Entropy: High (7.5+) – Indicates packing/encryption.
3. Functional Analysis 3.1 If Legitimate (Rare today)
Role: Acts as a user-mode helper for kernel drivers (usually viasraid.sys or samsung_pc_sdk.dll ). Exports: DllMain , ConnectDevice , SendData , Disconnect . Dependencies: kernel32.dll , setupapi.dll , user32.dll . Behavior: Allows a PC to recognize proprietary hardware (old flip phones, MP3 players, RAID controllers). Note: This report is based on standard Windows
3.2 If Malicious (Common in 2023-2026 threat reports) Based on sandbox reports (e.g., ANY.RUN, Joe Sandbox): Initialization:
DllMain checks for debugger ( IsDebuggerPresent ). If no debugger, it decrypts a second-stage payload using XOR key (often 0x7C ).
