Is SubtitleEdit-Windows-x64-Setup.exe safe?
Unsigned installer shares imphash with five prior OfferCore samples but triggers zero engines.
The file is unsigned and its imphash matches five previously seen OfferCore droppers, yet none of the 75 engines flagged it. Sandbox activity shows process injection (T1055) and direct-IP traffic, but no complete contacted-host reputation result was available reputation data is available.

Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer from the developer's official site or an official app store.
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.
The file is unsigned and its imphash matches five previously seen OfferCore droppers, yet none of the 75 engines flagged it. Sandbox activity shows process injection (T1055) and direct-IP traffic, but no complete contacted-host reputation result was available reputation data is available.
Zero engine detections normally point to clean, but the exact imphash has been tied to OfferCore malware five times in the last two weeks. The installer is unsigned, newly submitted, and exhibits process-injection behaviour in the single sandbox run. Contacted-host reputation was not completed, leaving the direct-IP traffic inconclusive. The combination of strong RAG malicious matches and absent detections creates mixed signals that warrant suspicion rather than a clean or malicious verdict.
What We Detected
75 engines scanned the file; none returned a malicious or suspicious result. The executable is unsigned despite being an installer. Its import hash exactly matches five prior samples that our analysis previously linked to the OfferCore downloader family.
Threat Behavior
One sandbox execution recorded MITRE technique T1055 (process injection) and direct-IP connections to 20 addresses. No domains were observed and no malicious verdict was issued by the sandbox itself. Host-reputation cross-check data is unavailable.
What To Do Now
Do not run the installer until additional reputation sources or a second sandbox run with host reputation can be obtained. Keep endpoint protection enabled.
Where this verdict could be wrong1 caveat
- All 75 engines returned undetected; no tier-1 or low-trust malicious labels present.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections across 75 engines
- No malicious sandbox verdict
- No malicious child files
- Unsigned installer
- Exact imphash match to five OfferCore droppers
- Process-injection technique observed in sandbox
- Newly submitted file (0 days)
Treat as suspicious; obtain additional sandbox runs with host reputation or wait for further prevalence data before execution.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Note: Collects details about your system.
Note: Loads extra code modules while running.
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
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
EvidenceC:\Windows\System32\RuntimeBroker.exe -EmbeddingThe 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.
