Is ProcessRunner.dll safe?
No antivirus engine detected this unsigned executable, but 21 YARA matches and runtime mappings for process injection and defense impairment warrant caution.
All 75 antivirus engines avoided flagging the sample, including 17 tier-1 products, and its observed domain had no adverse cache classification. However, the unsigned executable matched 21 community YARA rules and produced runtime mappings for process injection and defense impairment, so the evidence remains materially mixed.

Before using
Do not use it until the source and publisher can be verified independently.
If you already used it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

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.
All 75 antivirus engines avoided flagging the sample, including 17 tier-1 products, and its observed domain had no adverse cache classification. However, the unsigned executable matched 21 community YARA rules and produced runtime mappings for process injection and defense impairment, so the evidence remains materially mixed.
The strongest reassuring evidence is the 0/75 detection result, with all 17 reporting tier-1 engines silent. One completed sandbox run did not issue a malicious conclusion, the inspected child was not identified as malware, and the sole observed domain was fully checked without an adverse cache match. Against that, 21 YARA rules matched, including rules associated with script injection and debugger checks. Runtime evidence also mapped activity to T1055 and T1562.001, although those mappings do not establish intent or a specific injection implementation. Because the executable is unsigned and lacks trusted publisher history, the static and runtime concerns cannot be confidently attributed to a known legitimate vendor.
What We Detected
No antivirus product among 75 engines flagged the file, and all 17 reporting tier-1 engines returned no detection. The executable is unsigned and has no publisher-history evidence. It nevertheless matched 21 community YARA rules, including CP_Script_Inject_Detector and several debugger-check patterns.
Threat Behavior
One completed sandbox run mapped activity to process injection (T1055) and impairment of defenses (T1562.001), alongside several common application techniques. The sandbox did not produce a malicious conclusion. The sole observed domain, assets.msn.com, was covered by the host-reputation check without a malicious or suspicious cache match, and the inspected dropped child was not identified as malicious.
What To Do Now
Keep endpoint protection enabled and avoid loading the DLL on a production system until its source and expected purpose are verified. If it came from an untrusted download, quarantine it and obtain a fresh copy from the software vendor's official channel.
Where this verdict could be wrong3 caveats
- The 0/75 engine result, including 17 tier-1 engines without detections, weighs strongly against established malware.
- behaviour.hasMaliciousSandboxVerdict=false, droppedChildren.hasMaliciousChild=false, and the one observed host had no cached malicious or suspicious classification.
- similarHashes shows 1/1 prior verdict 'safe' for this imphash (matchKind=imphash, signerCoMatch=false), but an imphash-only collision is weak support.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines reported a detection
- All 17 reporting tier-1 engines returned no detection
- No malicious sandbox verdict
- No malicious dropped child identified
- The sole observed host was fully checked without an adverse cache classification
- Unsigned Windows executable with no established signer history
- 21 community YARA rules matched
- Runtime mapping to process injection technique T1055
- Runtime mapping to defense-impairment technique T1562.001
- Anti-debugging and long-sleep indicators
Keep security protections enabled and quarantine the file unless its origin and purpose can be verified. Test only in an isolated environment if operational validation is necessary.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Transferred a file over the network; malware can use this to fetch additional payloads.
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.

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.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't use it unless you're certain it came from a source you trust.
- Recovery step 02
Check where you got it — an unexpected attachment or a random download link is a red flag.
- Recovery step 03
Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
