Abstract: A system and method for performing full-stack blockchain analytics is disclosed. For example, blockchain analysis system comprises a blockchain operation module which integrates with the blockchain network and contains the data source that contains a plurality of blockchain data. The analysis system further comprises a blockchain analysis module that parses and analyzes the blockchain data. Additionally, the system comprises a blockchain tag module that determines a plurality of customizable tags based on the blockchain data and external data sources, and defines a low-level query interface that integrates customizable tags as objects into the blockchain data. The analysis system also comprises a blockchain search module that receives a blockchain search request, maintains a plurality of search indexes and a plurality of user-specific data, and determines a blockchain search result based on the blockchain search request and a plurality of tagged and untagged blockchain data.

Abstract: The main objective of Certificate Transparency (CT) is to detect mis-issued certificates or rouge certificate authorities. It has been observed that phishing sites have been increasingly acquiring certificates to look more legitimate and reach more victims, thus providing an opportunity to predict phishing domains early. The present disclosure provides systems and methods for early detection of phishing and benign domain traces in CT logs. The provided system may predict phishing domains early even before content is available via time-, issuer-, and certificate-based characteristics that are used to identify sets of CT-based inexpensive and novel features. The CT-features are augmented with other features including passive DNS (pDNS) and domain-based lexical features.
