We use anonymized flow data collected from a 10Gbps backbone link to discover and analyze malicious flow patterns. Even though such data may be rather difficult to interpret, we show how to bootstrap our analysis with a set of malicious hosts to discover more obscure patterns. Our analysis spans from simple attribute aggregates (such as top IP and port numbers) to advanced temporal analysis of communication patterns between normal and malicious hosts. For example, we found some complex communication patterns that possibly lasted for over a week. Furthermore, several malicious hosts were active over the whole data collection period, despite being blacklisted. We also discuss the problems of working with anonymized data. Given that this type of privacy-sensitive backbone data would not be available for analysis without proper anonymization, we show that it can still offer many novel insights, valuable for both network researchers and practitioners. |
