Where this verdict could be wrong1 caveat
- If this hash is a polymorphic-collision with a legitimate build, the MB label would be misleading — but MB curation makes this extremely rare.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- MalwareBazaar confirmed family: confirmed malware

What this file does
Observed actions and their security significance
High concern: Used an input-capture technique that can record credentials or keystrokes.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Moderate concern: Checks which security software you have installed.
Note: Inspects your network configuration.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file 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.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.

- INDICATOR_SUSPICIOUS_EXE_RawGitHub_URL
- maldoc_find_kernel32_base_method_1
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.

Complete recovery guidance and answers for the next decision.
What to do now
This file is dangerous. Treat it as harmful and remove it.
- Recovery step 01
Don't use this component. Quarantine this component with your antivirus, then repair or reinstall the parent software from its official source. Do not delete or replace the component manually.
- Recovery step 02
If you already used it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.
- Recovery step 03
From a different, clean device, change the passwords on your important accounts (email and banking first) and turn on two-factor authentication.
- Recovery step 04
Reinstall the parent software from the developer's official site instead of replacing this component by itself.
