Suspicious
Nuitka-compiled Python archive with process-injection and direct-IP contact patterns; weak tier-1 consensus and legitimate infrastructure contact suggest mixed signals.
c766dfdaa774a80a4b…804e20696eThe 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 sample exhibits offensive MITRE techniques (T1055 process injection, T1543 system process modification) and contacted external IPs without domain resolution, which are typically malware indicators. However, the evidence is ambiguous: ESET's single tier-1 flag lacks consensus (16 other tier-1 engines clean), the contacted IPs are public infrastructure used for certificate validation, and the dropped DLLs are standard Python runtime libraries. The Nuitka compiler and obfuscation (AGen suffix) suggest intentional packing, but this is common in legitimate penetration-testing and system-administration tools. No malicious sandbox verdict, no external intel corroboration, and no confirmed malicious children weigh against a malicious verdict. The weak tier-1 consensus combined with ambiguous C2 indicators places this in suspicious territory rather than malicious.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
ESET-NOD32 (tier-1) flags 'Python/Packed.Nuitka_AGen.MO suspicious application' — named family with obfuscation marker, but only 1/17 tier-1 engines agree (no strong consensus)
triggeredHeuristics: ProcessInjection (T1055, rundll32 + DLL loading) and DirectIpC2 (4 external IPs, zero domains) — both offensive patterns
Contacted IPs are public infrastructure (8.8.8.8 Google DNS, 104.18.38.233 Cloudflare, 162.159.36.2 Cloudflare, 172.64.149.23 Cloudflare) and OCSP certificate-validation URLs — not typical malware C2
Dropped children (10 files) all unknown verdict; no malicious children confirmed; no malicious sandbox verdict recorded
No external intel corroboration (YARAify=0 rules, CIRCL=no hit, MalwareBazaar=no hit); medium prevalence (6 submitters, 7 submissions) suggests emerging or niche tool
- 16 of 17 tier-1 engines reported clean — weak malicious consensus
- Contacted IPs are public infrastructure (Google DNS, Cloudflare) — not typical malware C2
- No malicious sandbox verdict recorded
- No external intel corroboration (YARAify, CIRCL, MalwareBazaar)
- No confirmed malicious dropped children
- Process injection via rundll32 (T1055) — payload smuggled into legitimate process
- Direct-IP contact without domain resolution — bypasses reputation-based blocklists
- Nuitka obfuscation (AGen suffix) — intentional code packing
- Unsigned binary — no publisher verification
- Generic tier-2 and low-trust detections — may indicate heuristic false positives
Treat this file as suspicious and avoid execution unless you can verify its origin and purpose from a trusted source. If already executed, monitor for unexpected process-injection activity or network connections to unfamiliar hosts. Consider submitting the sample to your security team for manual analysis.

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\libcrypto-1_1.dll",#1Sample contacted 4 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. 3 of 74 antivirus engines flag it (family: nuitka), 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 42.7 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.
- 3 of 74 antivirus engines flagged Trinity.zip, 3 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- 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.
- Trinity.zip is flagged as malicious (family: nuitka). Engines attribute it to the nuitka family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
- The SHA-256 hash of Trinity.zip is c766dfdaa774a80a4bcdfddf679ec2a09d8b372fe03c7e5b13e165804e20696e, and its MD5 is 3f7734d235366be39fcdb2c575ba8962. 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.
