Is meteor-rejects-addon-0.3.jar safe?
This file is a legitimate open-source Minecraft add-on for the Meteor Client, and the single heuristic detection from a low-trust engine is a false positive.
Our analysis identifies this file as a legitimate open-source Minecraft mod add-on. The single detection from a low-trust engine is a generic heuristic flag, which is common for such files and is not supported by any tier-1 antivirus engines.

Intelligence

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Our analysis identifies this file as a legitimate open-source Minecraft mod add-on. The single detection from a low-trust engine is a generic heuristic flag, which is common for such files and is not supported by any tier-1 antivirus engines.
The file is a known open-source Minecraft add-on, as evidenced by its presence in the official AntiCope GitHub repository. Our analysis shows that 74 out of 75 engines, including all 17 high-trust tier-1 engines, found no malicious activity. The single detection from a low-trust engine is a generic heuristic label, which is a common false positive for Java-based mods. No malicious behavior was observed during sandbox execution, and the file's prevalence and community context support its legitimacy.
What We Detected
Our analysis indicates that this file is a legitimate Minecraft add-on, specifically an add-on for the Meteor Client. It is hosted on the official AntiCope GitHub repository, which is a known source for such modifications. The single detection reported by a low-trust engine is a generic heuristic flag, which is common for Java-based mods and does not indicate actual malicious intent.
Threat Behavior
The file exhibited no malicious behavior during our sandbox analysis. Observed activities, such as Java runtime interactions and file system access, are consistent with the expected behavior of a Minecraft mod. no complete contacted-host reputation result was available or unauthorized system modifications were detected.
What To Do Now
This file is considered safe to use. As with any mod or third-party software, ensure you are downloading it from the official project repository to maintain security. Keep your endpoint protection enabled to monitor for any unexpected changes in system behavior.
Where this verdict could be wrong1 caveat
- MaxSecure flagged the file as 'Trojan.Malware.300983.susgen', but this is a lone low-trust detection lacking corroboration from any tier-1 engine.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- All 17 tier-1 engines reported the file as clean.
- The file is a known open-source project hosted on GitHub.
- No malicious behavior observed in sandbox analysis.
The file is safe to use as it is a legitimate Minecraft add-on. Ensure you download such mods only from official project repositories.

Detection sources at a glance
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
Low-severity pattern matches — worth noting but not on their own cause for alarm.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
