Is Symantec Authentication Client Extension safe?
Symantec Authentication Client Extension relays PKI commands from any web page to a locally installed native messaging host.
The extension injects a content script on every website (<all_urls>) that listens for CustomEvents dispatched by page JavaScript, then forwards those events to a background script which connects to the Symantec PKI Client native messaging host. Because the content script applies to all sites without restriction, any web page can trigger PKI and authentication operations on the user's locally installed Symantec Authentication Client. The extension also injects a detectable DOM marker into every page, allowing any in-page script to confirm whether the extension is installed.
