Safe
This is a legitimate signed installer for Stremio media software, showing clean scans and expected installation behavior despite minor heuristic flags.
67a71645bd213a8d80…f4f7ef3e77The verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
With zero malicious detections from high-coverage scans, including 17 tier-1 engines reporting clean, this file lacks any engine-based threat signals. It is properly signed by Smart Code OOD and matches the behavior of a standard InnoSetup installer for the popular Stremio application, including drops to the expected program directory. Triggered heuristics for process injection and direct IP contact are consistent with installer unpacking and multicast/Cloudflare resolutions, not C2. Medium prevalence and no malicious runtime indicators further support safety.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

YARA + heuristic rules that fired
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
EvidenceC:\Windows\Explorer.EXESample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.
