This page provides supplemental information, mainly about the inter-publisher dataset, for the paper Catching Worms, Trojan Horses and PUPs: Unsupervised Detection of Silent Delivery Campaigns , by BumJun Kwon, Virinchi Srinivas, Amol Deshpande, and Tudor Dumitraş.
Beewolf is a system for detecting silent delivery campaigns from Internet-wide records of download events. The key observation of the system is that the downloaders involved in these campaigns frequently retrieve payloads in lockstep. In a more detailed manner, when downloaders across the Internet are instructed to conduct a campaign, they will access a set of DNS domains to retrieve the payloads. This access typically happens in a short time window, and forms the key observation behind Beewolf. After a period of inactivity, the same downloaders will request additional payloads from a set of fresh domains.
By detecting these set of downloaders and domains in locksteps, we can discover unique business relationships from the underground economy. The inter-publisher graph above represents such relationships, by connecting those publishers which appear in the same lockstep.
Beewolf employ The Internet-wide records of download events, collected from the WINE platform. Then the system produces a list of locksteps, which are a set of downloaders and domains. In order to identify the writer(publisher) of the downloader, we query VirusTotal. Afterwards, we identify the publishers involved in a same delivery campaign. More detals on our collection and analysis can be found in our recent NDSS publication.
We are making our data available to the security community; we hope you will find it useful. The inter-publisher graph above is generated based on the publishers within the top 13 PUP-PPI locksteps (ranked by the maliciousness). The data used to produce the above inter-publiser graph can be found [link]. We are willing to share the full inter-publisher relationship detected by Beewolf.
