Is RecFlareSetup.exe safe?
Only 2 of 75 engines flagged this unsigned installer, but a T1055 runtime mapping and absent publisher authentication warrant caution before execution.
The detections are limited and generic: 2 of 75 engines flagged the file, while all 17 reporting tier-1 engines remained silent. However, the executable is unsigned and recently observed, and one sandbox mapped activity to T1055 process injection, so its exact source and hash should be verified before use.
2557c79fe1a0bd5355…f4ef3448d59fd0Recommended next actions
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.
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 detections are limited and generic: 2 of 75 engines flagged the file, while all 17 reporting tier-1 engines remained silent. However, the executable is unsigned and recently observed, and one sandbox mapped activity to T1055 process injection, so its exact source and hash should be verified before use.
Two of 75 engines produced generic detections, with no tier-1 family agreement. The completed sandbox did not return a malicious verdict, but it mapped one activity to MITRE T1055, which is unusual enough to retain concern. The executable is unsigned and has no established publisher history, weakening confidence in its identity. All six contacted domains were covered by the host-reputation check without malicious or suspicious results, and none of seven inspected children was identified as malicious, although their individual verdicts remain unknown. The imphash history trends concerning, but all five matches lack signer co-matches and may reflect a shared installer framework rather than a common payload.
What We Detected
DeepInstinct and Skyhigh flagged the sample, giving 2 detections among 75 engines. Skyhigh used the generic label “ObfuscatedPoly,” while no tier-1 engine identified a malware family. The file is an unsigned Windows installer first observed three days before this analysis.
Threat Behavior
One completed sandbox run mapped activity to MITRE T1055, associated with process injection, but the sandbox itself did not issue a malicious verdict. The sample downloaded components from GitHub and interacted with Steam infrastructure. The host-reputation check covered all six contacted domains and found no malicious or suspicious hosts; seven dropped children were inspected without a malicious finding, though their individual classifications remain unknown.
What To Do Now
Obtain the installer only from the project's official release channel and compare its SHA-256 value with a developer-published checksum. Keep endpoint protection enabled, and avoid running the file if its origin or hash cannot be authenticated.
Where this verdict could be wrong4 caveats
- All 17 reporting tier-1 engines were clean, and only 2/75 engines produced generic detections.
- The completed sandbox did not issue a malicious verdict, and droppedChildren.hasMaliciousChild=false.
- The filename and observed installer activity align with a public RecFlare installer project, but the file is unsigned and the exact hash was not independently authenticated.
- The prior imphash matches include an OffLoader sample, but signerMatchesSubject=false on every match, so a shared installer framework may explain the collision.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- All 17 reporting tier-1 engines remained clean
- Only 2 of 75 engines flagged the sample
- No malicious sandbox verdict was recorded
- All six contacted domains were covered with no malicious or suspicious host findings
- No malicious dropped child or external-intelligence hit was found
- Unsigned Win32 executable with no verified publisher identity
- MITRE T1055 process-injection mapping in one sandbox
- Two generic tier-2 antivirus detections
- First observed only three days before analysis
- Five imphash-related prior files include four concerning assessments and one OffLoader finding
- All seven dropped-child classifications remain unknown

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: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
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.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Reads your Windows user-account details.
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.

Detection sources at a glance
The available sources did not agree on a named threat category.
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.

What to do now
We couldn't fully clear this file. Treat it with caution.
- Recovery step 01
Don't run 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
If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Get a fresh copy from the developer's official site or an official app store.
- Recovery step 04
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.
