Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The installer has a verified Microsoft Corporation signature, long-standing prevalence, and no detections among 74 antivirus engines.
No antivirus engine detected the file, including all 17 reporting major antivirus engines. Its signature verifies to Microsoft Corporation, a curated trusted publisher, and 21 of 22 historical samples associated with that signer were assessed as benign. The exact file has circulated since 2010 and accumulated 64,289 submissions from 3,684 sources, which strongly supports an established Microsoft redistributable. Because the contacted IP addresses did not receive a complete saved reputation check, the network evidence remains unresolved rather than confirmed benign.
What We Detected
The file is a Windows Installer signed with a verified certificate belonging to Microsoft Corporation. None of the 62 antivirus engines that checked it detected malware or suspicious content, and all 17 reporting major antivirus engines were silent. The sample has also been widely observed since 2010, with 64,289 submissions across 3,684 sources.
Threat Behavior
One sandbox run installed Microsoft XNA and DirectX components and did not produce a malicious sandbox verdict. These findings are not corroborated by antivirus detections, malicious files it created, or researcher YARA rules. The sandbox contacted multiple IP addresses, but no complete host-reputation result is available because that cross-check was not saved.
What To Do Now
Prefer a copy obtained from Microsoft or a trusted game distributor, and verify that the digital signature remains valid before installation. Keep security software enabled, particularly if the installer came from an unofficial mirror or an unexpected download.
Where this verdict could be wrong4 caveats
- The sandbox's offensive-technique list includes T1055, T1485, T1486, T1543.003, T1548, and T1562.001, although the completed sandbox issued no malicious verdict.
- One of our behaviour rules reports apparent targeting of the Windows password store, but this rule is not corroborated by engine detections or a malicious sandbox verdict.
- One of our behaviour rules reports direct-IP contacts; the missing contacted-host reputation result means no complete reputation cross-check is available for those addresses.
- The signer-history record includes 1 malicious result among 22 historical Microsoft-signed samples, so signer identity is strong but not absolute evidence.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/62 antivirus engines detected the file.
- Verified signature from Microsoft Corporation.
- Microsoft matched the curated trusted-publisher list.
- Observed since 2010 with 64,289 submissions from 3,684 sources.
- No malicious child was found among 10 inspected dropped files.
- Sandbox rules mapped activity to and five other offensive MITRE techniques.
- Multiple direct-IP contacts lacked a complete saved host-reputation cross-check.
- The installer is old and may contain legacy components even though its signature verifies.
