whitepaper Emerging Trends in Fighting Spam26/03/08 Symantec
  Spam has been a serious problem for email administrators and users alike for more than five years, growing from one in six emails in 2002 to approximately three out of four emails today. This white paper focuses on the problems caused by image spam, as well as other spammer techniques for delivering content through existing spam-blocking defenses. The paper also discusses Symantec’s approach to solving the problem of image spam, botnets and other threats.  sponsored by
whitepaper Thwarting E-mail Spam Laundering2008-12-01 Association for Computing Machinery
  Laundering e-mail spam through open-proxies or compromised PCs is a widely-used trick to conceal real spam sources and reduce spamming cost in the underground e-mail spam industry. Spammers have plagued the Internet by exploiting a large number of spam proxies. The facility of breaking spam laundering and deterring spamming activities close to their sources, which would greatly benefit not only e-mail users but also victim ISPs, is in great demand but still missing. This paper reveals one salient characteristic of proxy-based spamming activities, namely packet symmetry, by analyzing protocol semantics and timing causality. Based on the packet symmetry exhibited in spam laundering, the paper proposes a simple and effective technique, DBSpam, to online detect and break spam laundering activities inside a customer network.

whitepaper Cisco 2008 Annual Security Report: Highlighting Global Security Threats and Trends2008-12-01 Cisco Systems
  There was an enormous amount of activity related to data and online security during the past year. Although no single, overwhelming attack - such as the spread of Melissa, Slammer, or Storm malware in previous years - turned into the signature security event of 2008, the need for increased security protection and continued vigilance remains. Threats that combine one or more online elements - the Web, spam, malware, and botnets - continue to grow in number and sophistication. For greater effectiveness, criminals are more and more often targeting specific individuals or groups and exploiting legitimate websites and other trusted entities and systems.

whitepaper Learning to Detect Spam: Naive-Euclidean Approach2008-11-29 University of Aizu
  A method is proposed for learning to classify spam and non-spam emails. It combines the strategy of the Best Stepwise Feature Selection with a classifier of Euclidean nearest-neighbor. Each text email is first transformed into a vector of D-dimensional Euclidean space. Emails were divided into training and test sets in the manner of 10-fold cross-validation. Three experiments were performed, and their elapsed CPU times and accuracies reported. The proposed spam detection learner was found to be extremely fast in recognition and with good error rates. It could be used as a baseline learning agent, in terms of CPU time and accuracy, against which other learning agents can be measured.

whitepaper A Phased Framework for Countering VoIP SPAM2008-11-29 Korea Information Security Agency
  VoIP spam will become severe problem preventing from generalization of VoIP service. For the purpose of presenting multi-leveled anti-spit framework, they divided VoIP service domain into three independent domains as an outbound, an intermediary, and an inbound domain. The proposed framework enables administrator to establish anti-spit policies in each domain. In outbound domain, the framework focuses on detecting and preventing spammers. The focus in intermediary domain is to block forged SIP message using sender policy framework. The framework enables victims to directly report spam contents they received to administrator. They showed that the multi-leveled anti-spit framework is enough to mitigate spam attacks.

whitepaper Spam Filtering With Several Novel Bayesian Classifiers2008-11-11 Institute of Electrical and Electronics Engineers
  This paper presents spam filtering with three novel bayesian classification methods: Aggregating One-Dependence Estimators (AODE), Hidden Naïve Bayes (HNB), Locally Weighted learning with Naïve Bayes (LWNB). Other four traditional classifiers: Naïve Bayes, k Nearest Neighbor (kNN), Support Vector Machine (SVM), C4.5 are also performed for comparison. Four feature selection methods: Gain Ratio, Information Gain, Symmetrical Uncertainty and ReliefF, are used to select relevant words for spam filtering. Results of experiments on two corpora show the promising capabilities of bayesian classifiers for spam filtering, especial for that of AODE.

whitepaper Artificial Immune System for Collaborative Spam Filtering2008-11-10 Ecole Polytechnique Federale de Lausanne
  Artificial Immune Systems (AIS) use the concepts and algorithms inspired by the theory of how the human immune system works. This paper presents the design and initial evaluation of a new artificial immune system for collaborative spam filtering. Collaborative spam filtering allows for the detection of not-previously-seen spam content, by exploiting its bulkiness. Their system uses two novel and possibly advantageous techniques for collaborative spam filtering. The first novelty is local processing of the signatures created from the emails prior to deciding whether and which of the generated signatures will be exchanged with other collaborating antispam systems. This processing exploits both the email-content profiles of the users and implicit or explicit feedback from the users and it uses customized AIS algorithms.
