Suspicious
Unsigned ZIP with process-injection and direct-IP C2 behaviour but zero engine detections.
2ca6e62003b09355ec…2f1f0dcc2aThe 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.
Zero malicious detections across 67 engines including 17 tier-1 engines rules out a strong malware consensus. However, the sandbox recorded T1055 process injection via rundll32 loading of dropped DLLs and direct-IP contact to three addresses without DNS resolution, both flagged by our synthesis heuristics. The file is unsigned, has only medium prevalence, and no prior similar-hash verdicts exist. These contradictory signals — clean engine results versus clear offensive behaviour — prevent a definitive safe or malicious classification.
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:\Windows\system32\rundll32.exe" "C:\Users\<USER>\AppData\Local\Temp\Trinity/vcruntime140.dll",#1Sample contacted 3 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.

Safety FAQ
Common questions about Trinity.zip, answered from the scan data above.
- Trinity.zip is suspicious — treat it as unsafe until you're sure. 0 of 75 antivirus engines flag it, which isn't a strong consensus but is enough to be cautious. Don't opened or extracted it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- Trinity.zip is a compressed archive, about 44.7 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- None — all 75 antivirus engines we queried report Trinity.zip as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Trinity.zip: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original Trinity.zip file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- The SHA-256 hash of Trinity.zip is 2ca6e62003b09355ecbb71cb1e7afc8e1123bb56a9b2e1d8f606772f1f0dcc2a, and its MD5 is ac63afc3ba37dc2a2bfd53937e53b158. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on July 11, 2026. Because a file's hash never changes, the identity of Trinity.zip is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
