Detection & Forensics
Consensus, attribution, signatures, code structure, prevalence, and identity.
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.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
This file appears low risk based on the evidence available now.
Open it only when its sender or download source is one you independently trust.
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
Keep your antivirus and Windows updates switched on so you stay protected.
