The reasoning behind this verdict

Analyst conclusion

None of the 61 antivirus engines that checked it flagged this JSON file, including all 17 major antivirus engines that returned a result. It is a plain data file, likely a cached copy of sync data. It did not match any malware database or researcher rule.

Where this verdict could be wrong2 caveats
  • The file is rare and was first seen on Oct 16, 2026, so it has little reputation history. For a plain data file that is common and not a risk on its own.
  • The reference-database lookup failed, so that corroborating source is unavailable for this file.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Is deltasync[1].json safe?

How many antivirus engines detected deltasync[1].json?
None of the 61 antivirus engines that checked it flag deltasync[1].json. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of deltasync[1].json?
The SHA-256 fingerprint of deltasync[1].json is d1dfa8fa3ef65237c51c98f5c02138428806d8e526e4909c2c5582b1a913cc25, and its MD5 is 9116abe3fb546f40ddf0fb4baf8822eb. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to open deltasync[1].json?
We found nothing harmful in deltasync[1].json. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of deltasync[1].json?
This report reflects the scan on Oct 16, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
