Rogue Elasticstack, replacing all protocols with Elasticstack

edit

I was capturing traffic through ethernet, when all of a sudden every single packet coming through turned into protocol Elasticstack, and all the fields appeared to be encrypted. I dont have Elasticstack. I contacted Elasticstack regarding this issue, they told me to reach out to Wireshark. So since you dont have any contact information at your company Wireshark, I feel this is the best place to start. Please explain to me what would cause this to happen. If packets never lie, then there might be something of value to learn from this. Thankyou.
