Is mod_generator.exe safe?
Unsigned 36 MB executable with one sandbox run showing T1486 and three low-trust detections.
Three low-trust engines flagged the file while tier-1 engines stayed silent. The binary is unsigned, wrote ten dropped children, and executed T1486 in a single sandbox run with no malicious verdict returned.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Three low-trust engines flagged the file while tier-1 engines stayed silent. The binary is unsigned, wrote ten dropped children, and executed T1486 in a single sandbox run with no malicious verdict returned.
The detection pattern is low-trust only, which normally leans safe, but the unsigned status, T1486 technique, and medium prevalence leave the file in mixed-signal territory. No tier-1 consensus, no sandbox malice verdict, and no external-intel hits prevent a malicious call. The absence of contacted-host reputation data and RAG history further limits certainty.
What We Detected
Three low-trust engines (APEX, Bkav, McAfeeD) reported malicious labels; 72 engines did not. The file is a 36 MB unsigned Win32 EXE that extracted ten runtime files and executed T1486 (data encrypted for impact) in one sandbox session without triggering a malicious verdict.
Threat Behavior
Static analysis shows high-entropy sections but no known packer. Sandbox activity was limited to writing temporary DLLs and creating a mutex; no C2 domains or malicious child processes were observed. No external-intel sources (CIRCL, MalwareBazaar, YARAify) returned hits.
What To Do Now
Keep endpoint protection enabled. Do not run the file on production systems until additional sandbox runs or code-signing verification can be obtained. Consider submitting the sample to more sandboxes for broader coverage.
- tier-1 engines silent
- no malicious sandbox verdict
- no malicious dropped children
- unsigned executable
- T1486 technique observed
- medium prevalence with no prior verdicts
Treat as untrusted; run additional sandbox analysis before any execution on sensitive systems.

What this file does
Observed actions and their security significance
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
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: Communicates over the network in a non-standard way.
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.
