When using WebEx, I get a continuous stream of messages from my firewall telling me that various hosts are attempting to access CiscoSparkPlugin.bundle on my computer. I'm asked whether to block or allow the connection. Looking at the hosts/ip addresses that are attempting this inbound connection shows that they are from all over the US, some in domains like ca.sfba.comcast.net or ca.ibone.comcast.net, or ip addresses like 23.30.207.42 and lots of others. These popups from my firewall are incessant. I've blocked all of these that have occurred, but I keep getting more (from different hosts). Some of these are even from webex.com, which may be legitimate, but since I don't know what CiscoSparkPlugin.bundle is, and can't find out much about this component, I'm leery about allowing any of these inbound connections.
Can someone explain what CiscoSparkPlugin.bundle is, and why I'm getting all these inbound connection requests? And whether I should allow or block them? I'm tempted to block all inbound connections to this component, but if I do, what will I break?
