Is 67 Client.jar safe?
Zero detections across 75 engines and no malicious children or sandbox verdict despite one offensive technique.
The file triggered no antivirus detections and produced no malicious dropped children or sandbox verdict. A single offensive MITRE technique (T1055) was observed, but without corroborating signals this remains a low-risk profile.

Before opening or running
Open or run it only when its publisher and download source have been independently verified.
If you already opened or ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
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.
The file triggered no antivirus detections and produced no malicious dropped children or sandbox verdict. A single offensive MITRE technique (T1055) was observed, but without corroborating signals this remains a low-risk profile.
All 75 reporting engines returned clean results, including 17 tier-1 engines. Sandbox analysis recorded T1055 process injection but returned no malicious verdict and no malicious no complete contacted-host reputation result was available. The file is brand-new and rare, yet the complete absence of detections and external-intel hits outweighs the single offensive technique.
What We Detected
75 engines scanned the JAR; none flagged it malicious or suspicious. Sandbox execution showed typical Java runtime behaviour plus T1055 process injection, but no malicious verdict or C2 traffic.
Threat Behavior
no complete contacted-host reputation result was available contacted, no malicious children dropped, and no external-intel hits from CIRCL, MalwareBazaar or YARAify. The single offensive technique is not corroborated by other signals.
What To Do Now
Keep antivirus enabled. If the file originates from an untrusted source, exercise normal caution; otherwise the evidence supports safe classification.
Where this verdict could be wrong1 caveat
- T1055 process-injection technique observed in sandbox; while not proof of malice, it is an offensive MITRE technique that requires scrutiny.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 engines malicious
- no malicious dropped children
- no external-intel hits
- rare_new prevalence
- T1055 process-injection technique observed
The file can be considered safe for normal use; continue running endpoint protection.

The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open or run it only when its publisher and download source have been independently verified.
- Recovery step 02
