Why does lsass.exe access the network?
While investigating lsass.exe with the GlassWire network security monitor on our devices based in Austin, TX USA we found a connection to a server controlled by a popular web browser called Opera am4.autoupdate.opera.com. This network activity appears to be normal behavior because we learned that lsass.exe is used to check website certificates and validate them. lsass.exe is also used to revoke bad website certificates. On our testing computer we had the Opera web browser installed.
