MKXP-Z game engine; 0/71 engines malicious; heuristic triggers (process injection, direct-IP contact) are benign for multimedia frameworks; 368-day prevalence with no tier-1 consensus.
1b9921a4fef0ee9128…836ca07d7aThe 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.
This file is MKXP-Z, an open-source Ruby-based game engine runtime. Despite two heuristic triggers — process injection (T1055) and direct-IP C2 contact — the universal clean verdict from 17 tier-1 engines (Avast, BitDefender, Kaspersky, ESET, Fortinet, and others) combined with 368 days of prevalence across 918 submitters indicates the heuristic patterns are benign. Game engines legitimately use process injection for DLL loading and rendering, and contact CDN IPs for asset delivery. No malicious sandbox verdict, no malicious dropped children, and no malicious contacted hosts in our cache further support a clean classification. The community comment tags are researcher annotations without engine corroboration.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines: 0/71 malicious; tier1Malicious=0 across Avast, BitDefender, Kaspersky, ESET, Fortinet, Ikarus, DrWeb, Emsisoft, GData, F-Secure — universal tier-1 clean consensus
triggeredHeuristics: 'MalwareTips.Synth.ProcessInjection' (T1055) and 'MalwareTips.Synth.DirectIpC2' fired, but these are heuristic evidence, not verdicts; no tier-1 engine corroboration
prevalence: common_old (918 submitters, 1307 submissions, 368 days) — widely distributed established file with no mass-escalation to malicious
behaviour: 1 offensive MITRE (T1055), 8 ambient, no malicious sandbox verdict, no malicious dropped children, no malicious contacted hosts; contacted IPs include private ranges and CDN infrastructure
filename 'mkxp-z.exe' is open-source game engine (MKXP-Z Ruby runtime); community tags reference #exeinfection #coinminer but are researcher annotations, not engine detections
- 0/71 engines malicious; universal tier-1 clean verdict
- 368-day prevalence (1,307 submissions) without escalation
- No malicious sandbox verdict, no malicious dropped children
- Contacted IPs include private ranges and known CDN infrastructure
- Filename matches known open-source game engine (MKXP-Z)
- Process injection (T1055) observed — but benign for game engines
- Direct-IP C2 contact (11 IPs, zero DNS) — but consistent with CDN asset delivery
- Unsigned executable — but common for open-source projects
- Community tags reference #coinminer and #qakbot — but no engine consensus
This file is safe to use if obtained from the official MKXP-Z repository. The heuristic triggers reflect legitimate game engine behaviour (process injection for rendering, CDN contact for assets), not malware activity. If you downloaded it from an unofficial source, verify the source and consider re-downloading from the official project.

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%SAMPLEPATH%\Game.exeSample contacted 11 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
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
