Is AutoPlay.exe safe?
Single low-trust detection on a 17-year-old Adobe-signed binary with YARA hits and MITRE process-injection techniques.
One low-trust engine flags the file as Trojan.Generic.hetyo while 17 tier-1 engines remain silent. The binary is signed by Adobe, yet it exhibits process-injection, service-creation and defense-evasion techniques and triggered four YARA rules from the research community.

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.
One low-trust engine flags the file as Trojan.Generic.hetyo while 17 tier-1 engines remain silent. The binary is signed by Adobe, yet it exhibits process-injection, service-creation and defense-evasion techniques and triggered four YARA rules from the research community.
The engine profile shows only low-trust flagging, which normally points to a false positive, but the presence of three offensive MITRE techniques and four YARA matches outweighs that signal. The Adobe signature is verified, yet the certificate is revoked and the file is 17 years old, reducing signer trust. Prevalence is high, but the combination of direct-IP traffic, process injection and YARA detections keeps the file in mixed-signals territory.
What We Detected
1/75 engines (Jiangmin) labels the sample Trojan.Generic.hetyo; 17 tier-1 engines report clean. The binary carries a verified Adobe signature whose certificate has since been revoked.
Threat Behavior
Runtime evidence shows MITRE techniques T1055 (process injection), T1543.003 (service creation) and T1562.001 (defense evasion). Four community YARA rules fired, including one targeting APT29 WINELOADER. The sample contacted 17 external IPs without domain resolution.
What To Do Now
Do not execute the file. Keep endpoint protection enabled and submit the sample to your security vendor for further analysis.
Where this verdict could be wrong1 caveat
- communityComments contain 2 'NO_THREAT' verdicts from FileScan.IO alongside 3 'SUSPICIOUS' — mixed third-party researcher opinions.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Verified Adobe signature
- 17 tier-1 engines report clean
- High historical prevalence
- Three offensive MITRE techniques observed
- Four YARA rules matched by community researchers
- Certificate revoked
- Direct-IP network traffic without domain resolution
Treat the file as suspicious; block or quarantine until additional vendor analysis is available.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Used an input-capture technique that can record credentials or keystrokes.
High concern: Created or modified a system service, which can keep code running.
High concern: Changed an auto-start location that can make code run after sign-in or restart.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Runs hidden system commands (script or shell).
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.

The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
Evidence"C:\Users\<USER>\Desktop\software.exe"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.
