# Flash Bulletin: Emotet Epoch 1 Changes its C2 Communication

**[cofense.com/flash-bulletin-emotet-epoch-1-changes-c2-communication/](https://cofense.com/flash-bulletin-emotet-epoch-1-changes-c2-communication/)**

Cofense March 15, 2019

We are currently noticing a change in the way that the Emotet botnet, specifically the epoch
1 variant, is communicating with the C2. In past versions, the client would typically perform a
GET request with data contained in the cookie value. As of approximately 11pm UTC on
March 14, this changed. The clients have begun to perform HTTP POSTs to what appear to
be their C2s. The URI’s contacted contain variable words in the paths. We are seeing form
data passed with a name variable and data. This change will break researchers as well as
certain detection technologies while they scurry to retool. We will continue to track this
change and analyze what this means. Further details to come.
