Verdict Malicious
Is sims-
6 of the 70 antivirus engines that checked it flag the file, including Microsoft major detection HackTool:Win64/Malgent!MSR.
Read the whole reasonShow less
Moderate evidence · Several antivirus engines agree.
Treat as malicious; delete the file and scan the system for any persistence mechanisms left behind.
What to do now4 steps
This is a hacking tool. It is risky to keep and run, but finding it is not by itself a sign that the device is infected.
What to do
Don't run it unless you got it on purpose for security testing on systems you own. Delete it, then empty the Recycle Bin.
If you didn't put it on the device yourself, delete it and run a full antivirus scan: something else may have brought it.
Tools like this often come with cracked or pirated software. If it came that way, treat the whole download as unsafe and scan everything it installed.
If you already ran it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.
If you opened or installed it
Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

Chapter 02
Why we think so
3 points against it and 2 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The signer 'Sims4Updater' has no prior reputation and the import-table fingerprint matches prior suspicious samples.
Microsoft's major detection plus Gridinsoft's matching label satisfy hacktoolConfirmed criteria. Observed MITRE techniques T1055, T1485, are offensive and corroborated by sandbox data. The signer lacks any historical samples, weakening any benign interpretation. Files built with the same import table previously received suspicious verdicts, and no external-intel or file it created evidence contradicts the malicious signals.
What We Detected
6 of the 70 antivirus engines that checked it report malicious, one of them major (Microsoft). The sample is signed by an unknown 'Sims4Updater' entity with an invalid certificate.
Threat Behavior
The binary contacted two raw IP addresses and wrote multiple PyInstaller-extracted files. No malicious files it created were dropped and external-intel sources returned no hits, but the offensive techniques alone meet hacking tool criteria.
What To Do Now
Do not execute the file. Keep security software enabled and remove the sample. If the file was downloaded from an official Sims 4 mod site, report the link to the site administrators.
Where this verdict could be wrong1 caveat
- The file is widely seen but new with 1312 submitters may indicate legitimate distribution despite offensive techniques.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No malicious files it created
- No external-intel corroboration
- Major antivirus engine labels it a confirmed hacking tool
- Unknown signer with no reputation history
- Direct-IP network traffic without domain context

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Checked whether it was running on a test computer.
Note: Read the user name of the test computer.
Note: Listed the programs running on the test computer.
Note: Deleted files or logs during the test run (installers often clean up after themselves).
Note: Talked to servers over the internet during the test run.
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: Showed activity a sandbox rule links to file encryption; no ransomware behaviour was confirmed.
Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
Threat context
How hacking tools are used
Hacking tools are programs that can switch off security software, test passwords or attack other computers. Security professionals use them on purpose; criminals also bundle them with malware.
Bottom line:Keep it only if you installed it on purpose, and check how it got onto the device if you didn't.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

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.
