Is manifest.json safe?
No engine among 75 flagged this small JSON manifest, and independent threat-intelligence checks found no family, signature, or matching research rule.
The 699-byte JSON manifest received no malicious or suspicious detections from 75 engines, including no flags from 17 tier-1 products. No external threat-intelligence matches or heuristic warnings were present, although runtime and contacted-host evidence were unavailable.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The 699-byte JSON manifest received no malicious or suspicious detections from 75 engines, including no flags from 17 tier-1 products. No external threat-intelligence matches or heuristic warnings were present, although runtime and contacted-host evidence were unavailable.
The file is a 699-byte JSON manifest, not a directly executable PE binary. None of 75 engines reported a malicious or suspicious result, and all 17 reporting tier-1 engines returned no detection. MalwareBazaar, CIRCL, and YARAify supplied no corroborating threat match, while no heuristic rule fired. Code signing is not meaningful for this file type, so the absence of a signature carries no negative weight. No sandbox execution or complete contacted-host reputation check is available, but the substantial static evidence contains no identified threat signal.
What We Detected
The sample is a 699-byte JSON manifest. None of 75 antivirus engines flagged it as malicious or suspicious, including Microsoft, Kaspersky, BitDefender, ESET-NOD32, Avast, and other tier-1 products.
Threat Behavior
No malware family, malicious signature, research rule, brand mismatch, or fired heuristic was identified. Runtime behavior was not observed because no completed sandbox result is available, and no comprehensive contacted-host reputation check was saved.
What To Do Now
No removal action is indicated by the available evidence. If this manifest belongs to a larger application or extension, assess the complete package and verify its source because a benign-looking configuration file does not establish the safety of every accompanying component.
Where this verdict could be wrong2 caveats
- behaviour=null, so there is no completed runtime observation to confirm how an application might consume this manifest.
- contactedHosts=null, so no complete host-reputation cross-check is available.
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 reported a malicious or suspicious result.
- engines.tier1ReportedClean=17 and engines.tier1Malicious=0.
- externalIntel.malwareBazaar.hit=false.
- externalIntel.yaraify.ruleCount=0.
- triggeredHeuristics contains no fired rules.
- No completed sandbox runtime observation is available.
- No complete contacted-host reputation cross-check is available.
No action is needed for this manifest alone. If it came with software or an extension, scan and verify the complete package before installation or use.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when its sender or download source is one you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
