In this post we explore a large collection of Sender Policy Framework (SPF) records to see what they might tell us about global email sending trust relationships and how they relate to email security providers. If you’re interested in discovering more interesting papers like these, use the method I outlined “short links” format was inspired by O’Reilly’s Four Short Links series.

Each of them uses machine learning or enables ML (i.e. Lastly, if you’re interested in discovering more interesting papers like these, use the method I outlined “short links” format was inspired by O’Reilly’s Four Short Links series.Ī short listing of cyber security data science research papers I’ve discovered recently.
Please see Auxiliary Loss Optimization for Hypothesis Augmentation for DGA Domain Detection. In a previous post, I also shared details on several models that are capable of effectively detecting dictionary DGA domains as well.
A Word-Level Analytical Approach for Identifying Malicious Domain Names Caused by Dictionary-Based DGA Malware. A Novel Detection Method for Word-Based DGA. Inline Detection of Domain Generation Algorithms with Context-Sensitive Word Embeddings. Dictionary Extraction and Detection of Algorithmically Generated Domain Names in Passive DNS Traffic. A Word Graph Approach for Dictionary Detection and Extraction in DGA Domain Names. Real-Time Detection of Dictionary DGA Network Traffic using Deep Learning. Below are a small sample of rovnix domains from Unit42’s blogpost. These domains may appear legitimate at first glance and are often able to evade blacklisting as well as traditional DGA detections based on entropy or counts of consonants vs vowels. Dictionary DGAs are algorithms seen in various malware families (suppobox, matsnu, gozi, rovnix, etc.) that are used to periodically generate a large number of domain names that use pseudo-randomly concatenated words from a dictionary. In this short blog, I share seven papers that focus on detecting Dictionary Domain Generation Algorithm (DGA) domains, A.K.A.
