Files signed by Blue Century Software Co., Ltd

Blue Century Software Co., Ltd

Blue Century Software Co., Ltd is a digital signature publisher name observed in ThreatInfo records. This page groups 18 signed files and shows whether those files are currently classified as clean, undefined, or detected.

A digital signature can help identify a publisher, but it does not always prove that a file is safe. Certificates may be abused, stolen, expired, or attached to modified installers, so the file hash and detection status should be checked together.

Certificate review summary

Use the file hashes to verify this signature

ThreatInfo groups the signed files above so you can compare exact hashes and detection labels. A signature name alone is not enough to decide whether a file is safe.

Recommended checks

  • Open any matching file report and compare the MD5 hash.
  • Confirm the file path and download source before trusting the binary.
  • Run a GridinSoft scan if the signed file appears unexpectedly.
