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
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence"C:\Windows\system32\rundll32.exe" "C:\Users\<USER>\AppData\Local\Temp\Qt5Core.dll",#1The 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. 10 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.
