NOTES:

• Today's post has two different Angler EK infections delivered by the EITest campaign.
• These two examples happened 16 minutes apart (one at 13:42 and the next at 13:58 UTC).
• The same Angler EK domain delivered a different payload each time.  First was Gootkit, and the second was Ursnif.
• Background on the EITest campaign can be found here.
