Behavioral profiles for advanced email features

Thomas Karagiannis, Milan Vojnovic
2009 Proceedings of the 18th international conference on World wide web - WWW '09  
We believe that our results provide significant insights towards informed design of advanced email features, including those of social-networking type.  ...  We highlight various novel threshold behaviors and provide support for existing hypotheses such as that of the least-effort reply.  ...  This would be of interest for an advanced email service, complemented with socialnetworking features. Future work may study other prediction models for email replies.  ...

EmailProfiler: Spearphishing Filtering with Header and Stylometric Features of Emails

Sevtap Duman, Kubra Kalkan-Cakmakci, Manuel Egele, William Robertson, Engin Kirda
2016 2016 IEEE 40th Annual Computer Software and Applications Conference (COMPSAC)  
The approach first builds probabilistic models of both email metadata and stylometric features of email content.  ...  Spearphishing is effective because it is fundamentally difficult for users to distinguish legitimate emails from spearphishing emails without additional defensive mechanisms.  ...  compare an incoming email against the behavioral profile extracted for the sender.  ...

Reading Between the Lines: Content-Agnostic Detection of Spear-Phishing Emails [chapter]

Hugo Gascon, Steffen Ullrich, Benjamin Stritter, Konrad Rieck
2018 Lecture Notes in Computer Science  
Based on these traits, we develop a method capable of learning profiles for a large set of senders and identifying spoofed emails as deviations thereof.  ...  Spear-phishing is an effective attack vector for infiltrating companies and organisations.  ...  These targeted attacks are more advanced than regular phishing or spam campaigns, as they are individually adapted to the environment and behavior of the victim.  ...

A Behavior-Based Approach to Securing Email Systems [chapter]

Salvatore J. Stolfo, Shlomo Hershkop, Ke Wang, Olivier Nimeskern, Chia-Wei Hu
2003 Lecture Notes in Computer Science  
The Malicious Email Tracking (MET) system, reported in a prior publication, is a behavior-based security system for email services.  ...  EMT includes a variety of behavior models for email attachments, user accounts and groups of accounts. Each model computed is used to detect anomalous and errant email behaviors.  ...  EMT is also being extended to include the profiles of the sender and recipient email accounts, and their clique behavior, as features for the supervised learning component.  ...

Goal-oriented Email Stream Classifier with A Multi-agent System Approach

Wenny Hojas-Mazo, Mailyn Moreno-Espino, José Vicente Berná Martínez, Francisco Maciá Pérez, Iren Lorenzo Fonseca
2021 International Journal of Advanced Computer Science and Applications  
The need to automate the email stream management increases for reasons such as multifolder categorization, and spam email classification.  ...  The behavior of agents was taking from an existing classifier.  ...  For example, features selection is intended to identify only those features with the highest discriminatory capacity to improve classifier performance [6] .  ...

2008 Proceedings of the 13th international conference on Intelligent user interfaces - IUI '08  
Both problems use the same underlying email classification system and task specific features. Each task is evaluated for both single-user and cross-user settings.  ...  We present two prediction problems under the rubric of Intelligent Email that are designed to support enhanced email interfaces that relieve the stress of email overload.  ...  Profiles were constructed for each Enron user from emails not in the evaluation corpus.  ...
