Unsigned security-software-named EXE triggers only low-tier engines and direct-IP heuristic, matching AV-on-AV false positive with all tier-1 engines clean.
dfb3d004af508f27f4…37ac62bdfbThe 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.
The detection profile shows minimal flags from non-tier1 engines with generic labels, a hallmark of heuristic false positives on security tools. Filename 'AiDefend.exe' and analysis flags confirm security software resemblance. Behavioural signals like direct Cloudflare IP contact trigger a heuristic but align with common app patterns, lacking offensive MITRE or sandbox malice. Unsigned status and rarity add minor risk, but clean tier1 consensus and no corroborating intel outweigh them.
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
One or more medium-severity heuristic rules matched. Not definitive, but the patterns match known malware behaviour.
Sample 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.

Section entropy & packers
Section-level entropy and packer detection from the PE header. Nothing suspicious here — entropy is within the normal range for unpacked code.
How often this file shows up in the wild
Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.
