Malicious
This unsigned binary exhibits suspicious process token manipulation and direct-IP communication, characteristic of malicious activity rather than legitimate software behavior.
4c46067b1f88d5cc05…03cf8c8183The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
Our analysis identifies the file as unsigned, which immediately increases the risk profile. The behavioral report confirms the use of T1134, a technique used to manipulate process tokens, alongside the creation of a DLL in a sensitive system path. Furthermore, the direct-IP communication detected by our heuristics is a common tactic used by malware to evade domain-based security controls. While the engine detection count is low, the combination of these specific offensive behaviors provides a clear signal of malicious activity.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

What this file does
What it attempted when executed in an isolated sandbox
High concern: Sets itself to run automatically every time you start your PC.
Moderate concern: Obfuscates or packs its code to avoid detection.
Moderate concern: Scans through your files and folders.
Moderate concern: Checks whether it's being watched in a sandbox before acting.
Moderate concern: Connects out to 3 servers on the internet.
Note: Collects details about your system.
Note: Loads extra code modules while running.
Translated from the file's technical behaviour during analysis. It never ran on your device.
Threat context
How trojans work
A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.
What to do now
This file is dangerous. Treat it as harmful and remove it.
Don't open or run this file. Delete it from your Downloads (or wherever you saved it), then empty the Recycle Bin.
If you already opened it, disconnect from the internet and run a full scan with your antivirus — Windows Security, built into Windows, is sufficient.
If you typed any passwords while it was open, change them from a device you trust.
In future, only download software from the official website or an official app store.

YARA & heuristic rule matches
One or more medium-severity heuristic rules matched. Not definitive, but the patterns match known malware behaviour.
Sample 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 fffx301.exe, answered from the scan data above.
- Yes — fffx301.exe is malicious, so do not run it, and delete it. 2 of 74 antivirus engines flag it (family: fitin). It behaves as a trojan — malware disguised as something harmless to trick you into running it. If you've already run it, see the removal and recovery steps below.
- fffx301.exe is a Windows executable program, about 7.5 MB. Our analysis identifies it as malicious (family: fitin) — a trojan — malware disguised as something harmless to trick you into running it. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
- 2 of 74 antivirus engines flagged fffx301.exe, 2 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- 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 fffx301.exe: 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 fffx301.exe 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.
- fffx301.exe is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the fitin 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 fffx301.exe is 4c46067b1f88d5cc05a82eca5ada04ddc2f877724686863858238303cf8c8183, and its MD5 is e975468efe5cd3a89f119237c46d1980. 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 17, 2026. Because a file's hash never changes, the identity of fffx301.exe 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.
