What our analysis found
ІІТ Користувач ЦСК-1. Бібл. підп. (web-р.), used by 800,000 people, showed no malicious code in Extension Auditor's review. It was last updated in December 2022.
Analyst notes
The extension acts as a bridge between web pages and a locally installed digital signature application via native messaging. No outbound network requests, data exfiltration, or tracking are present. All data handling is local. The ML model likely flagged the extension due to innerHTML usage, base64 encoding, and broad content script injection—all of which are required for the extension's legitimate purpose. The manifest mismatch (bundled manifest v2 with tabs permission and broad content_scripts vs. CWS summary showing manifest v3 and limited host_permissions) is likely a listing artifact and not malicious intent.
