Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
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.
All 75 engines returned clean results. The file is signed by Microsoft Corporation and matches five prior safe verdicts from the same signer. Sandbox and child-file checks show no malicious indicators.
Zero malicious detections across the full engine set, including 17 tier-1 engines, removes any detection-based risk. The verified Microsoft signature and 100 % safe historical samples for this signer provide strong provenance. Five similar hashes previously classified safe under the same signer reinforce the pattern. The single heuristic trigger for direct-IP traffic points only to Apple infrastructure no complete contacted-host reputation result was available. No dropped malicious children or malicious host contacts exist.
What We Detected
75 antivirus engines scanned the 6.9 MB Apple package; none flagged it. The package carries a valid Microsoft Corporation code-signing certificate that our trusted-publisher list recognizes. Historical samples signed by the same certificate have a 7-of-7 clean record.
Threat Behavior
Sandbox execution produced only ambient system calls and contacted Apple infrastructure IPs for certificate validation. Ten child files were created; none matched known malware. No persistence mechanisms or offensive MITRE techniques were observed.
What To Do Now
The package can be considered safe for installation. Keep endpoint protection enabled and download future Microsoft software only from official channels.
- Verified Microsoft Corporation signature
- Zero engine detections across 75 scanners
- Consistent safe history for this signer
Install with confidence; the evidence indicates the file is a legitimate Microsoft software package.
Coverage & freshness

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
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
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.
