Suspicious
Unsigned JAR installer shows process injection and direct-IP contact despite zero engine detections.
f384ff363b4fbf522f…6208da89b7The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
The complete absence of engine detections, including 17 tier-1 clean reports, is a strong safe signal. However, the sandbox captured three offensive MITRE techniques and direct-IP C2 behaviour that triggered high-severity heuristics. Being unsigned with no signer history removes the usual trust anchor for installers. Medium prevalence and clean dropped children prevent a malicious call, but the behavioural mismatch keeps the file in mixed-signals territory.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines: 0 malicious detections, 17 tier-1 clean reports
behaviour.offensiveTechniques: T1055, T1543.002, T1562.001
behaviour.contactedIps: 162.159.36.2 (direct IP, no DNS)
signing.verified: false (unsigned JAR)
triggeredHeuristics: MalwareTips.Synth.ProcessInjection (high severity)
- Zero detections across 65 reporting engines
- 17 tier-1 engines reported clean
- No malicious dropped children
- Medium prevalence across 27 submitters
- Unsigned JAR with no signer history
- Sandbox observed T1055 process injection
- Direct-IP contact without DNS resolution
- Persistence indicators via T1543.002
Treat as untrusted until the behavioural signals can be attributed to legitimate mod-loader activity; do not execute on production systems without isolation.
What this file does
What it attempted when executed in an isolated sandbox
High concern: Hides inside another running program to evade antivirus.
High concern: Downloads more malware onto your PC.
High concern: Installs itself as a Windows service to stay running.
High concern: Tries to disable or bypass your security software.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Checks whether it's being watched in a sandbox before acting.
Moderate concern: Checks which security software you have installed.

What to do now
We couldn't fully clear this file. Treat it with caution.
Don't run it unless you're certain it came from a source you trust.
Check where you got it — an email attachment or a random download link is a red flag.
If you're unsure, delete it. You can always re-download a clean copy from the official source.
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence"C:\Program Files\Java\jre-1.8\bin\javaw.exe" -jar "C:\Users\<USER>\Desktop\runtime.jar"Sample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

Safety FAQ
Common questions about Jenny-Mod-Installer-26.2.jar, answered from the scan data above.
- Jenny-Mod-Installer-26.2.jar is suspicious — treat it as unsafe until you're sure. 0 of 74 antivirus engines flag it, which isn't a strong consensus but is enough to be cautious. Don't run it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- Jenny-Mod-Installer-26.2.jar is a software installer, about 31.8 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- None — all 74 antivirus engines we queried report Jenny-Mod-Installer-26.2.jar as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Jenny-Mod-Installer-26.2.jar: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original Jenny-Mod-Installer-26.2.jar file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- The SHA-256 hash of Jenny-Mod-Installer-26.2.jar is f384ff363b4fbf522f2dd8a814d08567093d332a141fc025452bf56208da89b7, and its MD5 is b2b3698fa9ec71b3d2a1927162196ad6. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on July 20, 2026. Because a file's hash never changes, the identity of Jenny-Mod-Installer-26.2.jar is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
