Is UPDFSetup.exe safe?
No engine detected malware, the installer carries a verified signature, and the limited runtime concerns lack malicious corroboration, though one contacted IP remains unchecked.
All 75 antivirus engines produced no detection, including 17 tier-1 engines, and the executable is validly signed by Superace Software Technology Co. One sandbox observed two offensive-associated techniques and direct-IP traffic, but issued no malicious verdict; the contacted IP did not receive a complete reputation check.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines produced no detection, including 17 tier-1 engines, and the executable is validly signed by Superace Software Technology Co. One sandbox observed two offensive-associated techniques and direct-IP traffic, but issued no malicious verdict; the contacted IP did not receive a complete reputation check.
The strongest evidence is the complete absence of detections across 75 antivirus engines, with all 17 tier-1 participants reporting no detection. The executable is validly signed by Superace Software Technology Co., and no brand conflict was identified, although there is no historical signer record. One completed sandbox run recorded T1134 and T1562.001, but it produced no malicious sandbox verdict or persistence indicators. Ten dropped files were inspected without a malicious child finding, though their individual verdicts remain unknown. A low-severity heuristic noted direct traffic to 162.159.36.2, and no complete host-reputation result is available. The five similar-file results are weak counter-evidence because they share only an imphash and do not match this signer.
What We Detected
No malware or suspicious detections were reported among 75 antivirus engines, including 17 tier-1 engines. The executable has a verified signature from Superace Software Technology Co., and the available metadata shows no signer-to-brand mismatch. No malware family was identified by external research intelligence.
Threat Behavior
One completed sandbox run observed T1134 and T1562.001 alongside common installer activity, but it did not issue a malicious sandbox verdict or record persistence indicators. The sample contacted 162.159.36.2 directly; because the host-reputation cross-check was not completed or saved, that endpoint cannot be described as clean. Ten dropped files were inspected without a malicious-child finding, although their individual classifications remain unknown.
What To Do Now
Use a copy obtained from the publisher's official download channel and verify that Windows still reports the signature as valid before installation. Keep endpoint protection enabled and rescan if the signature changes, the installer came from an unofficial source, or unexpected network or system activity appears.
Where this verdict could be wrong5 caveats
- T1134 and T1562.001 can be associated with token manipulation and impaired defenses, so their appearance deserves caution despite the absence of a malicious sandbox verdict.
- The sample contacted 162.159.36.2 directly, and contactedHosts=null means no complete reputation cross-check is available for that endpoint.
- signing.signerStats.found=false, so the verified certificate is not backed by established historical sample statistics.
- All 10 dropped-child verdicts are unknown; hasMaliciousChild=false therefore does not establish that each child is benign.
- similarHashes contains 5/5 prior suspicious results, but all are imphash-only matches with signerMatchesSubject=false and different filenames.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines reported a malicious or suspicious detection.
- All 17 tier-1 engines reported no detection.
- The signature for 'Superace Software Technology Co.' is verified.
- behaviour.hasMaliciousSandboxVerdict=false after one completed sandbox run.
- droppedChildren.hasMaliciousChild=false across 10 inspected children.
- Sandbox observed offensive-associated techniques T1134 and T1562.001.
- Direct-IP traffic to 162.159.36.2 lacks a completed host-reputation cross-check.
- signing.signerStats.found=false provides no established publisher history.
- The 10 dropped children have unknown individual verdicts.
Install only if the file came from the publisher's official channel and its signature remains valid. Keep endpoint protection enabled and rescan if any source or signature detail differs.

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
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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.
