Is MalachiTemp.zip safe?
ZIP archive containing MSILHeracles binaries flagged by seven tier-1 engines as PUA/GameHack.
Seven tier-1 engines label the contents as unwanted or MSILHeracles variants; sandbox shows two offensive MITRE techniques but no malicious verdict. Medium prevalence and no malicious children keep the file in mixed-signals territory.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Seven tier-1 engines label the contents as unwanted or MSILHeracles variants; sandbox shows two offensive MITRE techniques but no malicious verdict. Medium prevalence and no malicious children keep the file in mixed-signals territory.
The sample is a ZIP that extracts multiple .NET DLLs executed via rundll32. Engines converge on the MSILHeracles / UnwantedX family with seven tier-1 detections, yet the family consensus is only two engines and the labels are PUA-oriented. Sandbox recorded persistence and anti-debug techniques but returned no explicit malicious verdict. Ten dropped children were clean and no host-reputation data exists for the single direct-IP contact.
What We Detected
29 of 74 engines flagged the archive; 7 tier-1 engines returned malicious results, primarily naming MSILHeracles or UnwantedX PUA. Sandbox execution showed two offensive MITRE techniques (T1543.002 Create Service, T1562.001 Impair Defenses) and direct-IP contact to 162.159.36.2.
Threat Behavior
The archive drops ten DLLs that are subsequently loaded by rundll32. No malicious child files were identified and no domain-based C2 was observed. Prevalence is medium with 86 unique submitters.
What To Do Now
Do not execute the archive on production systems. If the files are required for legitimate development or research, run them only in an isolated virtual machine with current security software enabled.
Where this verdict could be wrong1 caveat
- contactedHosts is null — no complete host-reputation result available for IP 162.159.36.2.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No malicious dropped children
- Medium prevalence across 86 sources
- No brand-mismatch or adversarial filename
- 7 tier-1 engines flag the contents
- Offensive MITRE techniques observed in sandbox
- Direct-IP contact without domain context
Treat as potentially unwanted software; keep endpoint protection enabled and avoid execution outside controlled environments.

What this file does
Observed actions and their security significance
High concern: Created or modified a system service, which can keep code running.
High concern: Attempted to impair or bypass security controls.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Moderate concern: Checks which security software you have installed.
Note: Collects details about your system.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
