Verdict Safe
Is meteorextras-
No antivirus engine detected this JAR, and its completed sandbox run produced no malicious conclusion, though two offensive-associated techniques warrant source verification.

Why we think so
3 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The sample drew no detections from 75 antivirus engines, including 17 major antivirus engines, and one completed sandbox run produced no malicious conclusion. Two offensive-associated techniques were recorded, but there were no observed network contacts, confirmed malicious files it created, or external intelligence matches.
One completed sandbox run did not produce a malicious conclusion or record any contacted domains, IP addresses, or URLs. It did record and T1562.001, which are meaningful counter-signals but are not corroborated by detections, persistence indicators, or hostile network activity. Five written-file hashes were inspected without a confirmed malicious child, although their individual verdicts remain unknown. Researcher-curated sources supplied no YARA, CIRCL, or MalwareBazaar match, while 57 submitters and 64 submissions indicate moderate circulation.
What We Detected
None of the 64 antivirus engines that checked it flagged the JAR, including 17 major antivirus engines. Researcher-curated checks also returned no YARAify rules, CIRCL match, or MalwareBazaar entry.
Threat Behavior
One completed sandbox run produced no malicious conclusion and recorded no contacted domains, IP addresses, or URLs. It did associate the execution with T1543.002 and T1562.001, so those behaviors remain cautionary signals. Five child hashes were inspected without a confirmed malicious result, but each child still lacks a conclusive individual verdict. No complete contacted-host reputation result was saved.
What To Do Now
Obtain the mod from its official project page or another trusted repository and verify the SHA-256 hash before installation. Keep security software enabled, and avoid granting the JAR unnecessary administrative privileges.
Where this verdict could be wrong3 caveats
- The runtime record includes and T1562.001, techniques associated with service activity and impairment of defenses, so the sample should still come from a trusted mod source.
- All five inspected files it created have unknown verdicts rather than confirmed benign results.
- The missing contacted-host reputation result means no saved host-reputation cross-check is available, although the sandbox recorded no network contacts.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/64 antivirus engines reported a malicious or suspicious result.
- No sandbox returned a malicious verdict in one completed sandbox run.
- No domains, IP addresses, or URLs were recorded by the sandbox.
- No CIRCL, MalwareBazaar, or YARAify match was found.
- Evidence from the test run includes offensive-associated techniques and T1562.001.
- Five inspected child hashes have unknown individual verdicts.
- The missing contacted-host reputation result leaves host-reputation coverage unavailable.
