Verdict Suspicious

Analyzed , 2 months ago

Is SteamDaddy.exe safe? Treat it as suspicious.

The signer has no history and the file was first seen on Aug 19, 2026.

Why Suspicious? 3 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't run it until you know where it came from

Treat as suspicious; isolate and analyze further before any execution on production systems.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Not sure what to do?

Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

The combination of a ML detection from a major antivirus engine, offensive MITRE techniques, and access to the Windows password store creates a mixed but concerning signal. The majority of major antivirus engines remained silent and no sandbox verdict was malicious, yet the unknown signer and short history (submitted shortly before Aug 22, 2026) prevent a clean classification. No external intelligence or prior similar-hash verdicts exist to resolve the ambiguity.

Where this verdict could be wrong2 caveats
  • 15 major antivirus engines reported it clean and 1 major antivirus engine flagged it — majority of major antivirus engines did not flag.
  • No sandbox returned a malicious verdict despite offensive MITRE techniques observed.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

  • Note: Read basic details of the test computer, such as its Windows version.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as recording keystrokes; no keylogging was confirmed.

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

I already downloaded and ran SteamDaddy.exe — what should I do?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
Is SteamDaddy.exe digitally signed?

How up to date is this analysis of SteamDaddy.exe?
This report reflects the scan on Aug 22, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
