Emerging Trends in Fighting Spam | 26/03/08 | 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 Symantecs approach to solving the problem of image spam, botnets and other threats. | sponsored by![]() |

Best Practices in Using Reputation-Based Anti-Spam Services for Email Security | 2009-02-01 | Cisco Systems |
| One of the most efficient, least costly and, remarkably, most effective anti-spam techniques is IP reputation filtering. An incredibly inexpensive technique for the anti-spam gateway, IP reputation filtering can be used to identify 80 percent (or more) of spam without even looking at message content. IP reputation services have become a best practice for any anti-spam gateway. This white paper discusses the origins of IP reputation services; test results on Cisco IronPort's own reputation service, SenderBase; best practices in using reputation services; and the ROI of reputation services.

Fighting Spam With the NeighborhoodWatch DHT | 2009-01-19 | university of maryland |
| This paper presents DHTBL, an anti-spam blacklist built upon a novel secure Distributed Hash Table (DHT). They show how DHTBL can be used to replace existing DNS-based Blacklists (DNSBLs) of IP addresses of mail relays that forward spam. Implementing a blacklist on a DHT improves resilience to DoS attacks and secures message delivery, when compared to DNSBLs. However, due to the sensitive nature of the blacklist, storing the data in a peer-to-peer DHT would invite attackers to infiltrate the system. Typical DHTs can withstand fail-stop failures, but malicious nodes may provide incorrect routing information, refuse to return published items, or simply ignore certain queries. The NeighborhoodWatch DHT is resilient to malicious nodes and maintains the O(logN) bounds on routing table size and expected lookup time.

Towards Automating Malware Classification and Characterization | 2009-01-01 | Seewald Solutions |
| Spam has become a problem of global impact. Most spam messages are currently sent out by captured machines organized in bot networks, which are infected with malicious software and are therefore under direct control of spammers. The connected explosion of automatically generated new malware variants has manual analysis at a great disadvantage, while classical automated analysis systems have problems keeping up with the diversity of new variants. Here, the paper proposes using machine learning approaches to learn global (i.e. malware intent) and local (i.e. specific functionality) malware properties based on behavioral traces of malware recorded in virtual environments, and tests them on a small corpus. Initial results are somewhat promising, so they also discuss areas for improvement as well as current and future challenges.

Using Visual Features for Anti-Spam Filtering | 2009-01-01 | University of California |
| Unsolicited Commercial Email (UCE), also known as spam, has been a major problem on the Internet. In the past, researchers have addressed this problem as a text classification or categorization problem. However, as spammers' techniques continue to evolve and the genre of email content becomes more and more diverse, text-based anti-spam approaches alone are no longer sufficient. This paper proposes a novel anti-spam system which utilizes visual clues, in addition to text information in the email body, to determine whether a message is spam. They analyze a large collection of spam emails containing images and identify a number of useful visual features for this application. They then propose using one-class Support Vector Machines (SVM) as the underlying base classifier for anti-spam filtering.

Spam Filtering Using a Markov Random Field Model With Variable Weighting Schemas | 2009-01-01 | University of California |
| This paper presents a Markov Random Field model based approach to filter spam. Their approach examines the importance of the neighborhood relationship (MRF cliques) among words in an email message for the purpose of spam classification. They propose and test several different theoretical bases for weighting schemes among corresponding neighborhood windows. Their results demonstrate that unexpected side effects depending on the neighborhood window size may have larger accuracy impact than the neighborhood relationship effects of the Markov Random Field.

Stopping Spam by Extrusion Detection | 2009-01-01 | University of Cambridge |
| End users are often unaware that their systems have been compromised and are being used to send bulk unsolicited email (spam). This paper shows how automated processing of the email logs recorded on the "Smarthost" provided by an ISP for their customer's outgoing email can be used to detect this spam. The variability and obfuscation being employed by the spammers to avoid detection at the destination creates distinctive patterns that allow legitimate email traffic to be distinguished from spam at the source. Some relatively simple heuristics result in the detection of low numbers of "False positives" despite tuning to ensure few "False negatives".
