Detection sources at a glance
The available sources did not agree on a named threat category.
This legacy report does not record whether the independent reference checks completed.
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\shell.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.
