Is meteor-client-26.2-25.jar safe?
No antivirus engine identified malware, and the lone sandbox produced no malicious conclusion, although several offensive-technique mappings justify retaining normal endpoint protections.
None of 75 antivirus engines flagged this JAR, including all 17 tier-1 engines, and one completed sandbox run produced no malicious conclusion. The T1055, T1543.002, and T1562.001 mappings remain cautionary, but they lack corroboration from engine detections, malicious children, network contacts, or external intelligence.

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.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
None of 75 antivirus engines flagged this JAR, including all 17 tier-1 engines, and one completed sandbox run produced no malicious conclusion. The T1055, T1543.002, and T1562.001 mappings remain cautionary, but they lack corroboration from engine detections, malicious children, network contacts, or external intelligence.
The strongest evidence is broad engine agreement: 0 of 75 engines raised a malicious or suspicious detection, including 17 tier-1 engines. One completed sandbox run did not produce a malicious conclusion and recorded no contacted domains, IPs, or URLs. Static and runtime mapping nevertheless associated the sample with T1055, T1543.002, and T1562.001, so the behavior is not entirely routine. Those mappings are not corroborated by malicious dropped children, YARA rules, known-malicious intelligence, or antivirus family labels. The file also received 212 submissions from 194 sources in five days, indicating broad recent circulation rather than an isolated sample. Host-reputation checking was not saved, and all seven dropped-child verdicts remain unknown, which limits confidence.
What We Detected
None of 75 antivirus engines flagged the JAR, and all 17 tier-1 engines reported no detection. External intelligence also supplied no MalwareBazaar hit, CIRCL match, or YARAify rule match. The sample has circulated broadly for its age, with 212 submissions from 194 sources within five days.
Threat Behavior
One completed sandbox run produced no malicious conclusion and recorded no contacted domains, IP addresses, or URLs. It mapped activity to T1055, T1543.002, and T1562.001, including possible process injection and defense impairment, but these mappings do not by themselves establish hostile intent. Seven dropped files were inspected without a malicious child being identified; however, their individual verdicts remain unknown. No complete contacted-host reputation result is available because the host cross-check was not saved.
What To Do Now
Use the file only if it came from the expected project or distribution channel, and keep antivirus and endpoint protection enabled. If the source is unfamiliar, verify its SHA-256 and obtain a fresh copy from the official publisher before execution.
Where this verdict could be wrong3 caveats
- The runtime mapping includes T1055 process injection, T1543.002 system services, and T1562.001 impairment of defenses; these capabilities warrant caution despite the absence of engine detections.
- contactedHosts=null means no saved host-reputation cross-check is available, though behaviour.contactedDomains, contactedIps, and contactedUrls were empty.
- All seven dropped children have unknown individual verdicts, so droppedChildren.hasMaliciousChild=false does not establish that those files are benign.
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 antivirus engines reported malicious or suspicious findings.
- All 17 tier-1 engines reported no detection.
- behaviour.hasMaliciousSandboxVerdict=false after one completed sandbox run.
- No domains, IP addresses, or URLs were recorded during the sandbox run.
- No MalwareBazaar, CIRCL, or YARAify hit was present.
- Runtime evidence mapped possible process injection to T1055.
- Runtime evidence mapped system-service activity to T1543.002.
- Runtime evidence mapped possible defense impairment to T1562.001.
- The file was first observed only five days ago.
- No complete contacted-host reputation cross-check is available.
- All seven dropped-child verdicts remain unknown.
Keep endpoint protection enabled and obtain the JAR from the expected official distribution channel. Avoid running it if its source or hash cannot be independently verified.

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.
