Is mm.exe safe?
Only Trapmine flagged this long-established file with a generic machine-learning label, though packing, T1055 activity, and unchecked IP reputation warrant ordinary caution.
Only 1 of 75 engines flagged the sample, and that detection came from low-trust Trapmine rather than a tier-1 engine. Its long prevalence history and lack of a malicious sandbox verdict favor a false positive, although packing, T1055 activity, and incomplete IP-reputation coverage leave some residual uncertainty.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Only 1 of 75 engines flagged the sample, and that detection came from low-trust Trapmine rather than a tier-1 engine. Its long prevalence history and lack of a malicious sandbox verdict favor a false positive, although packing, T1055 activity, and incomplete IP-reputation coverage leave some residual uncertainty.
The antivirus result is dominated by non-detections: only Trapmine flagged the file among 75 engines, using a generic machine-learning label, while no tier-1 engine detected it. The file has also circulated since 2010 across 148 sources, which is difficult to reconcile with a newly emerging unidentified threat. One completed sandbox recorded activity mapped to T1055 and external IP contacts, while static analysis found likely packing and high-entropy code. Those findings are concerning but are not corroborated by a malicious sandbox verdict, a malicious dropped child, a named malware family, or external intelligence. Because host-reputation coverage was not saved, the no complete contacted-host reputation result was available or malicious from this evidence.
What We Detected
Trapmine was the only engine among 75 to flag the executable, assigning the generic label “suspicious.low.ml.score.” No tier-1 engine detected it, and there was no family consensus or confirmed hacktool label. The file is unsigned, but it has been observed since 2010 and submitted by 148 distinct sources.
Threat Behavior
One sandbox run mapped activity to MITRE T1055, associated with process injection, and recorded several external IP contacts. Static PE inspection also found high-entropy code and likely packing. However, the sandbox did not issue a malicious verdict, and neither of the two inspected dropped children was confirmed malicious. A complete reputation check was not available for the contacted hosts, so the no complete contacted-host reputation result was available.
What To Do Now
Obtain the executable from its original trusted source and verify its hash before running it. Keep endpoint protection enabled; if the file's origin or purpose is unclear, test it in an isolated environment or avoid execution.
Where this verdict could be wrong3 caveats
- The unsigned executable is likely packed, and the sandbox evidence maps activity to T1055 process injection.
- The sample contacted external IP addresses, but contactedHosts=null means no complete reputation result is available for those contacts.
- The sole similar-hash result was suspicious, although it is only an imphash match without signer co-matching and therefore may reflect a packer or framework 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.
- Only 1/75 engines detected the sample
- engines.tier1Malicious=0
- The sole detection was a generic low-trust Trapmine label
- No malicious sandbox verdict or confirmed malicious child
- Observed since 2010 across 148 sources
- Unsigned Win32 executable
- Likely packed with high-entropy code
- Sandbox evidence mapped activity to MITRE T1055
- External IP contacts lack a complete reputation cross-check
- One prior imphash-only match received a suspicious assessment
Use only a copy obtained from a trusted original source and keep endpoint protection enabled. If provenance cannot be established, avoid running it or evaluate it in an isolated environment.

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.
Evidence"C:\Users\<USER>\AppData\Local\Temp\software.exe"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.

Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
