Is BBRWSetup.EXE safe?
One high-trust worm detection and runtime injection-related techniques raise concern, but broad engine disagreement and absent independent intelligence prevent firm family confirmation.
Three of 75 engines flagged this unsigned installer, with Ikarus naming Alcaul and Zillya naming Viking. Runtime evidence mapped process injection and token manipulation, but the sandbox did not issue a malware finding, most high-trust engines remained silent, and no external intelligence source corroborated either family.

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.
Three of 75 engines flagged this unsigned installer, with Ikarus naming Alcaul and Zillya naming Viking. Runtime evidence mapped process injection and token manipulation, but the sandbox did not issue a malware finding, most high-trust engines remained silent, and no external intelligence source corroborated either family.
The strongest detection is Ikarus's Alcaul label, supported loosely by Zillya's different Viking worm label and Google's generic detection. The single completed runtime observation mapped T1055 and T1134, which are offensive techniques and materially increase concern. However, only 3 of 75 engines flagged the file, there is no strong tier-1 family consensus, and the sandbox did not return a malicious finding. The executable is unsigned and recently observed, so there is no verified publisher identity or established signer history to offset those concerns. Similar-file history includes one malicious and one suspicious result, but both are imphash-only links without signer co-matching and therefore cannot establish identity. No complete contacted-host reputation result is available, although the recorded run listed no network contacts.
What We Detected
Three of 75 antivirus engines flagged the executable. Ikarus identified Email-Worm.Win32.Alcaul, Zillya identified Worm.Viking.Win32.22518, and Google returned a generic detection; the differing labels and tier1FamilyConsensus.strong=false mean the proposed worm family is not firmly established.
Threat Behavior
One completed sandbox run mapped T1055 process injection and T1134 access-token manipulation. These are significant offensive techniques, although the sandbox itself did not issue a malware finding. Six child files were inspected, but every child remains unclassified, so they neither confirm nor clear the parent. No complete contacted-host reputation result is available; the recorded execution contained no domains, IPs, or URLs to cross-check.
What To Do Now
Do not run the file on a production system unless its origin and expected publisher can be independently verified. Keep endpoint protection enabled, quarantine the executable, and obtain a fresh installer directly from the vendor's official release channel before proceeding.
Where this verdict could be wrong5 caveats
- Only 3/75 engines detected the sample, while 16 of 17 reporting tier-1 engines did not flag it.
- behaviour.hasMaliciousSandboxVerdict=false, and the completed sandbox labeled its run clean despite mapping T1055 and T1134.
- externalIntel shows no CIRCL, MalwareBazaar, or YARAify hit, although absence may reflect intelligence-coverage gaps.
- peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false, providing no static indication of packing or unusually entropic code.
- The two similar-hash links are imphash-only matches without signer co-matching, so shared build tooling could explain the overlap.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 3/75 engines reported a detection.
- 16 of 17 reporting tier-1 engines did not flag the sample.
- behaviour.hasMaliciousSandboxVerdict=false.
- No CIRCL, MalwareBazaar, or YARAify match was found.
- peAnalysis indicates neither likely packing nor high-entropy code.
- Ikarus identified Email-Worm.Win32.Alcaul.
- Zillya independently applied a Viking worm label.
- Runtime evidence mapped T1055 process injection.
- Runtime evidence mapped T1134 access-token manipulation.
- The executable is unsigned and has no signer history.
- The file was first observed only one day before analysis.
Quarantine the file and verify its source before execution; prefer a newly downloaded copy from the publisher's official channel. Keep antivirus and endpoint protection enabled.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
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.
Moderate concern: Scans through your files and folders.
Moderate concern: Checked the environment for virtualisation or analysis tools.
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
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
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.
