Suspicious
Signed Outbyte Camomile installer flagged as PUA/grayware by DrWeb and CrowdStrike, with process injection and direct IP behavior, but contacts vendor site and lacks strong malware consensus.
3d3dbd5885ff6e931f…220d232db0The 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.
Low detection count (2/71) dominated by PUA/grayware labels aligns with security-tool-like filename and classifier heuristic. Verified signature from Outbyte, a known optimizer vendor, but limited signer history raises mild concern. Behavioral signals like T1055 injection and direct IPs are suspicious yet contextualized by legitimate vendor contacts and no malicious runtime outcomes. Absence of tier-1 malware consensus, clean children/hosts, and medium prevalence support PUA over threat. Overall mixed signals warrant caution without clear malicious intent.
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.
Evidence"C:\Users\<USER>\Desktop\outbyte-camomile-setup.exe"Sample contacted 2 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.
