Is utorrent_installer 3.6.0.exe safe?
uTorrent installer signed by Rainberry Inc but flagged by 6 tier-1 engines as OfferCore PUA with credential-access behaviour.
Six tier-1 engines and four agreeing on the OfferCore family label this file malicious. Sandbox shows credential dumping and browser theft techniques, yet the file is signed by the legitimate uTorrent publisher and contacts only clean infrastructure.

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.
Six tier-1 engines and four agreeing on the OfferCore family label this file malicious. Sandbox shows credential dumping and browser theft techniques, yet the file is signed by the legitimate uTorrent publisher and contacts only clean infrastructure.
The strong tier-1 consensus on OfferCore combined with offensive MITRE techniques T1003 and T1555.003 outweighs the clean signer and lack of malicious no complete contacted-host reputation result was available precedents but two suspicious ones. The file is common and old, reducing the chance of a brand-new threat, but the credential-access behaviour remains a clear risk factor.
What We Detected
16 of 76 engines flagged the sample; 6 tier-1 engines converged on the OfferCore PUA family. Sandbox execution recorded 13 offensive MITRE techniques including credential dumping (T1003) and browser credential theft (T1555.003). The binary is signed by Rainberry Inc and verified, but the signer has no prior history in our database.
Threat Behavior
The installer drops multiple temporary files, creates persistence via rsSyncSvc, and contacts 17 external no complete contacted-host reputation result was available. No malicious children were dropped and no known-malicious infrastructure was reached. However, the observed access to browser credential stores and wallet files is consistent with adware/PUP monetization rather than benign installation.
What To Do Now
Do not run the file if the goal is a clean uTorrent installation. Prefer the official standalone torrent client from the vendor site or a package manager. Keep endpoint protection enabled; the PUA classification itself is the actionable signal.
Where this verdict could be wrong2 caveats
- contactedHosts.inspected=17, maliciousHosts.length=0 — no complete contacted-host reputation result was available contacted.
- droppedChildren.hasMaliciousChild=false, 10 children inspected with no malicious verdicts.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Signed and verified by Rainberry Inc (uTorrent publisher)
- no complete contacted-host reputation result was available or dropped children
- Common and old prevalence (448 sources)
- Strong tier-1 consensus on OfferCore PUA family
- Sandbox shows credential dumping and browser theft techniques
- 13 offensive MITRE techniques observed

What this file does
Observed actions and their security significance
High concern: Accessed operating-system credential data, which can expose saved passwords.
High concern: Created or modified a scheduled task, which can provide persistence.
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
High concern: Created or modified a system service, which can keep code running.
High concern: Configured an event-triggered execution mechanism.
High concern: Changed an auto-start location that can make code run after sign-in or restart.
High concern: Searched files or settings where passwords and keys may be stored.
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.

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.
