Jps_Virus_Maker

Overview

JPS Virus Maker (cataloged across security software as HackTool:Win32/JPSVirusMaker, Tool:Win32/JPS, and Constructor.Win32.JPS) is a classical GUI-based virus creation kit and malware generator from the early 2000s cybercrime era. Similar to Senna Spy and VBSWG toolkits, JPS Virus Maker allowed novice cybercriminals to generate custom Windows trojans and destructive script payloads by selecting pre-configured options (such as disabling Windows Task Manager, formatting floppy drives, modifying desktop registry policies, and injecting backdoor ports) without writing code.

Indicators of Compromise

Public indicators drawn from CISA advisories and vendor reporting. These are historical and intended for retrospective threat hunting; current campaigns may use different infrastructure. SystemHelpDesk adheres to responsible disclosure and does not host live samples.

File hashes (SHA-256, sample)

Cryptographic hashes serve as reference indicators for triage and detection rules. In accordance with responsible threat intelligence disclosure, this catalog indexes reference metadata and does not host or distribute live malware binaries.

Delivery vectors

• Underground hacker forums and malware repository archive packages
• Peer-to-peer file-sharing networks packaged as hacking utility collections

Persistence mechanisms

• HKLM\Software\Microsoft\Windows\CurrentVersion\Run\JPSMakerPersistence
• Registry policy modification disabling Task Manager and Regedit

Tiered Detection Rules (Cisco CAIRN Model)

Modern threat detection requires multi-layered rule engineering. We classify detections into three operational tiers based on signal fidelity:

rule MALWARE_WIN_JPS_VIRUS_MAKER_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Jps_Virus_Maker"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "jps_virus_maker" ascii wide nocase
        $s2 = "hacktool:win32/jpsvirusmaker" ascii wide nocase
        $s3 = "tool:win32/jps" ascii wide nocase
        $s4 = "constructor.win32.jps" ascii wide nocase
        $s5 = "win32/jps.constructor" ascii wide nocase
        $s6 = "jpsvirusmaker.tool" ascii wide nocase
    condition:

Containment & Response Steps

Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.

1. Quarantine and delete all instances of the JPS Virus Maker generator toolkit from the filesystem.
2. Scan endpoints for any compiled output binaries generated using the toolkit and eliminate them.
3. Restore disabled registry administrative policies using administrative group policy overrides.
4. Audit file servers and shared network drives for generated dropper executables.

What to Avoid

Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.

1. Do not execute software downloaded from underground malware author forums or hacking repositories.
2. Avoid disabling antimalware protection to run compiled hacktools or generators.
