Attacked by powerful actors.
No resources.
High political value.
No knowledge.
Not their goal.
Trust
Privacy
Help NGOs/CSOs from the University.
Stratosphere Project
Apply Machine Learning to detect malicious behaviors in the network by respecting the privacy.
Analyzes large amounts of malicious and normal flows
Stratosphere Project
Largest Academic Botnet Dataset for Research: CTU-13
+130 Published Labeled Malware Datasets.
Verified Normal Traffic from hosts in the University.
Privacy and Performance
Model the behavior of each connection
Stratosphere Project
Each flow has features that define its state.
Each state is assigned a letter.
Detect the malicious behaviors by analyzing the letters
Stratosphere Project
Markov Models
Neural Networks
Behavior of the Host
From the letters create a Markov Chains behavioral model
Stratosphere Project
Obtain the behavior of all the connections
Stratosphere Project
The models of malicious behaviors are stored and grouped.
Detect similar behaviors in unknown networks.
