Is OTP Bot Builder.rar safe?
No antivirus engine identified the archive, but an unclassified extracted executable and observed defense-impairment technique make execution inappropriate without further verification.
All 76 antivirus engines avoided flagging this archive, and the completed sandbox run did not produce a malicious verdict. However, it extracted an executable that remains unclassified and recorded defense-impairment technique T1562.001, so the contents should not be run on a normal system.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 76 antivirus engines avoided flagging this archive, and the completed sandbox run did not produce a malicious verdict. However, it extracted an executable that remains unclassified and recorded defense-impairment technique T1562.001, so the contents should not be run on a normal system.
The antivirus results are strongly favorable: 0 of 76 engines detected the archive, including no tier-1 detections. One completed sandbox run did not return a malicious verdict, and no malicious child was established. However, the run recorded T1562.001, and the extracted builder executable received no completed child verdict. No curated external-intelligence source corroborated malware, while contaminated community annotations were not relied upon. These mixed findings support caution rather than treating the archive as established benign software.
What We Detected
The RAR archive received 0 detections from 76 antivirus engines, with all 18 reporting tier-1 engines returning it as undetected. CIRCL, MalwareBazaar, and YARAify supplied no corroborating hit. Community annotations alleged an infostealer connection, but the comment field was marked as containing instruction-like contamination, so those claims were downweighted and were not accepted as proof.
Threat Behavior
One completed sandbox run extracted builder.exe and recorded MITRE technique T1562.001, which concerns impairing defenses. The sandbox did not issue a malicious verdict, no persistence indicators were recorded, and no network contacts appeared in the observed run. The extracted executable remains unclassified, however, and no complete contacted-host reputation result is available.
What To Do Now
Do not execute the archive's contents on a normal or production system. Keep endpoint protection enabled, obtain the software from a verifiable source, and separately scan or analyze the extracted executable in an isolated environment before considering use.
Where this verdict could be wrong3 caveats
- T1562.001 indicates possible impairment of defenses, an offensive behavior that is not explained by the antivirus results.
- The extracted builder.exe child has no completed child verdict; droppedChildren.rollup.unknown=1 leaves the archive's principal executable incompletely assessed.
- Five communityComments associate the hash with Stealerium, but commentInjectionSuspected=true and no engine, sandbox verdict, or external-intelligence result independently corroborates that family.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/76 antivirus engines reported a detection.
- All 18 reporting tier-1 engines returned undetected.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false.
- CIRCL, MalwareBazaar, and YARAify returned no hits.
- behaviour.offensiveTechniques includes T1562.001.
- The archive extracts builder.exe, whose child verdict remains unknown.
- The filename indicates an OTP bot-building utility with unclear provenance.
- No complete contacted-host reputation result is available.
- Community annotations allege Stealerium, although those annotations are contaminated and uncorroborated.
Avoid running the archive or its extracted executable unless its origin and purpose can be independently verified. Keep security protection enabled and use an isolated analysis environment for any further testing.

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: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Collects details about your system.
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.
