Is FreeRIP_setup.exe safe?
Unsigned NSIS installer flagged by three tier-1 engines as PUA with LSASS access observed in sandbox.
Three tier-1 engines label the file as YTDDownloader PUA or Siggen32; sandbox shows LSASS access and direct-IP traffic. No malicious children or known-bad hosts detected, yet the file remains unsigned with offensive MITRE techniques.

Before installing
Do not install it until the source and publisher can be verified independently.
If you already installed it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Download a fresh installer 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 tier-1 engines label the file as YTDDownloader PUA or Siggen32; sandbox shows LSASS access and direct-IP traffic. No malicious children or known-bad hosts detected, yet the file remains unsigned with offensive MITRE techniques.
The combination of tier-1 PUA detections, LSASS credential-dumping behaviour, and unsigned status outweighs the clean child and host checks. Medium prevalence and long history reduce immediate risk but do not clear the behavioural red flags. Direct-IP C2 heuristic is inconclusive because host reputation coverage is incomplete.
What We Detected
Three tier-1 engines (DrWeb, ESET-NOD32, Microsoft) flag the sample as YTDDownloader PUA or Siggen32. Sandbox execution recorded LSASS access and four offensive MITRE techniques (T1485 data destruction, T1547.001 persistence, T1548 privilege escalation, T1562.001 defence evasion).
Threat Behavior
The installer writes multiple NSIS helper DLLs, creates several mutexes, and initiates outbound connections to 15 IPs without domain names. No dropped children were flagged malicious and none of the four inspected contacted hosts appear in our malicious cache.
What To Do Now
Do not run the installer. If already executed, review installed programs for FreeRIP and inspect autoruns for persistence entries. Keep endpoint protection enabled and consider a full malware scan of the affected system.
Where this verdict could be wrong2 caveats
- contactedHosts.inspected=4 covers only 4 of 15 distinct IPs; no complete host-reputation result available for remaining IPs
- similarHashes matchKind=imphash(signerCoMatch=false) is framework collision, not strong similarity
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- medium prevalence, 2652-day history
- no malicious dropped children
- no complete contacted-host reputation result was available
- unsigned executable
- LSASS access observed
- tier-1 PUA detections
- direct-IP outbound traffic
Treat as unwanted software; avoid installation and remove if present.

What this file does
Observed actions and their security significance
High concern: Used an input-capture technique that can record credentials or keystrokes.
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.
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.
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.

Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
Sandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe 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.
