Is polarity-meq-0.1.5-windows-system.exe safe?
Possible process injection and LSASS-related activity raise concern, but only 2 of 75 engines flagged the unsigned file and no high-trust consensus exists.
The strongest concerns are the T1055 process-injection mapping, LSASS-related activity, and lack of a verified signature. However, only 2 of 75 engines detected it, all 17 reporting tier-1 engines were clean, and neither the sandbox verdict nor external research sources supplied decisive malware confirmation.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

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 strongest concerns are the T1055 process-injection mapping, LSASS-related activity, and lack of a verified signature. However, only 2 of 75 engines detected it, all 17 reporting tier-1 engines were clean, and neither the sandbox verdict nor external research sources supplied decisive malware confirmation.
Two of 75 engines flagged the executable with generic malicious or obfuscation labels, while all 17 reporting tier-1 engines remained clean. Runtime evidence maps activity to T1055 and records LSASS-related process activity, which is concerning but does not prove credential dumping by itself. The file is unsigned and only four days old, leaving no established publisher history to offset those concerns. One direct IP was observed, but no complete host-reputation result is available because the contacted-host check was not saved. Similar-imphash files have unfavorable prior outcomes, although the lack of signer co-matches makes installer-framework collision a material limitation. No malicious sandbox verdict, malicious dropped child, strong family consensus, or external research match establishes a specific malware family.
What We Detected
DeepInstinct and Skyhigh flagged the file, producing 2 detections across 75 engines. Skyhigh used the generic label ObfuscatedPoly, while no tier-1 engine identified malware and no family consensus formed. The executable is unsigned and has no publisher history.
Threat Behavior
The completed runtime observation mapped activity to MITRE T1055 and recorded LSASS-related process activity. These are meaningful warning signs, but the saved evidence does not prove a specific injection method or confirmed credential theft. The file also contacted 162.159.36.2 directly; because contacted-host reputation was not checked or saved, that connection cannot be characterized as benign or malicious. Two dropped children were inspected without a malicious child finding, but both individual outcomes remain unknown.
What To Do Now
Do not run the file on a production or personal system until its source and expected publisher can be independently verified. Keep endpoint protection enabled, quarantine the file if it has already been downloaded, and investigate any execution for unusual LSASS access or injected processes.
Where this verdict could be wrong5 caveats
- All 17 reporting tier-1 engines were clean, including BitDefender, ESET-NOD32, Kaspersky, and Fortinet.
- behaviour.hasMaliciousSandboxVerdict=false, so the completed sandbox did not issue a malware verdict.
- droppedChildren inspected 2 hashes and hasMaliciousChild=false, although both child verdicts remain unknown.
- externalIntel.malwareBazaar.hit=false and externalIntel.yaraify.ruleCount=0 provide no researcher-curated corroboration.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false do not support the generic obfuscation label.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 2/75 engines reported malicious results.
- tier1Malicious=0, with all 17 reporting tier-1 engines clean.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false.
- Runtime evidence includes MITRE T1055 process-injection mapping.
- LSASS-related activity triggered MalwareTips.Synth.CredentialDumper.
- The Windows executable is unsigned and has no signer history.
- A direct IP connection to 162.159.36.2 lacks a completed reputation check.
- Three similar-imphash records previously received malicious outcomes.
- The file was first observed only four days ago.
Quarantine the executable and verify its download source, expected publisher, and hash before use. If it already ran, keep protection enabled and inspect the endpoint for LSASS access and process injection.

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: Reads your Windows user-account details.
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.

MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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\svchost.exe -k NetworkService -pSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe 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.
