Most are not. ● Few are transparent as to listing and delisting criteria. ● Few have good IPv6 coverage. ● Useful as a first pass to cut down on spam passing to the rest of the filtering stages. www.roaringpenguin.com Domain Reputation ● Also typically implemented by DNSBLs. ● Reactive. ● Low to moderate hit rate. ● May be applied to sending domain and/or to domains of URLs in the message body. www.roaringpenguin.com Domain Reputation - 2 ● Spammers often register throwaway domains as sending domains. ● Idea: Penalize messages from “newly-seen” domains. ● CanIt 10.1.7 tracks domains seen across all CanIt installations and permits you to (mildly) penalize mail from only-recently-seen domains. www.roaringpenguin.com Authentication: SPF ● SPF (Sender Policy Framework) is a mechanism whereby domain owners can declare which machines may send email on their domains’ behalf. ● For arbitrary domains, an SPF “pass” is a mild spam indicator! ● Spammers are better at setting up SPF than many legitimate administrators. www.roaringpenguin.com Authentication: SPF - 2 ● SPF is useful for trusted domains (banks, PayPal, eBay, etc.) ● Adding points on SPF “fail” or “softfail” is useful. ● Subtracting points on SPF “pass” for arbitrary domains is dangerous. ● Subtracting points on SPF “pass” for trusted domains is useful.

Dabei müssen häufig persönliche und vertrauliche Daten über das Internet versendet werden. Diese sind ein attraktives und lukratives Ziel für Online-Kriminelle, die heute international organisiert und professionell strukturiert zusammen arbeiten. IT-Kriminalität ist für die Angreifer ein lohnenswertes Geschäft bei vergleichsweise niedrigem Risiko. Identitätsdiebstahl und Angriffe mit Schadprogram- men unterschiedlichster Art gehören bei der Nutzung des Internets zu den ernstzunehmenden Bedrohungen für alle Anwender.

It is not only fundamental, but also a must. Users may become impatient when mails were delayed, not to mention failed to access their emails. – Imagine we meet the situation of power failure or cut of water supply 3 Architecture of a Simple Mail System Consists of the following components – MTA - Mail transfer agent Sending and forwarding emails Server end – MDA - Mail delivery agent Delivering emails to recipients’ mailbox Server end – Pop3/Imap4 Daemons For users to download their mailboxs Server end – MUA - Mail user agent Reading and composing emails 4 Client end Architecture of a Simple Mail System Protocols Used for Mail System Protocols – For computer programs to communicate with each other – Similar to languages that human beings speak SMTP – Simple Mail Transfer Protocol – Too simple to provide any “advanced features” Authentication Authorization POP3 – Post Office Protocol version 3 – Simple IMAP4 – Internet Message Access Protocol version 4 – Fully compatible with internet message standards, e.g. MIME. – Allow messages to be accessed from more than one computer. – Provide support for online, offline, and disconnected modes. 6 – Multiple and share folders.

Acknowledgements I thank Raphael Reischuk for his tireless effort and for the immense amount of time he invested in me and the project. His enthusiasm motivated me throughout the project. He taught me countless things and was more friend than supervisor. I thank hYuuBluei for giving me the opportunity to write this thesis. I cost hYuuBluei and its employees a lot of time and nerves. I am thankful for their patience and for being so understanding. ii Abstract Social engineering, the act of manipulating people into committing actions ben- eficial to an attacker (and most likely detrimental to the manipulated target), is as old as time itself and is likely to remain a dangerous threat to organizations and individuals alike | especially today, in times where information is more valuable than ever before. In order to better understand the implications of social engineering, this thesis constitutes research on social engineering in the context of an internation- ally operating organization. More specifically, the thesis presents the planning and execution of various social-engineering attacks that were performed over the course of approximately two months. All attacks were conducted without any insider knowledge about the targeted organization.

Post-acceptance tests involve instead a and deployed in the past decade, their impact and effectiveness number of local tests, such as the use of a classifier on the is not always clear. In particular, on top of the most common email body. content- and sender-based anti-spam techniques, two minor approaches are popular among system administrators to cope While the most popular techniques have been widely with this annoying problem: greylisting and nolisting. These studied in previous research [3]–[5], [11], [18], [22], [23], techniques exploit known features of the Simple Mail Transfer [28], [29], [35], [36], [38], the effectiveness of other minor Protocol (SMTP) protocol that are not often respected by spam bots.

  • Lecture Notes for Web Security 2019 Part 5 — E-Mail Security Martin Hell
    Lecture Notes for Web Security 2019 Part 5 | E-mail Security Martin Hell This chapter will discuss some different security aspects of emails. In order to understand these aspects, it is necessary to understand the SMTP protocol, i.e., how emails are sent from one user to another, and what the messages look like. 1 The SMTP Protocol SMTP (Simple Mail Transfer Protocol) is the most common protocol used to transfer emails. It was first defined in RFC 821 [6], which was obsoleted by RFC 2821 [4], which was again obsoleted by RFC 5321 [5]. The email architecture consists of several building blocks, see Figure 1. • MUA - Mail User Agent. This is the source and target of emails and is responsible for delivering the email to the MSA. Typical examples are Eudora, Outlook, Pine and Kmail. • MSA - Mail Submission Agent. This receives the message from the MUA and delivers it to the MTA. This is usually implemented together with the MTA instead of being a standalone program. The MSA can implement security checks on the email, e.g., checking that it is not spam, before sending it to the MTA. Message submission uses TCP port 587 and is discussed in RFC 4409 [3]. • MTA - Mail Transfer Agent. This is the building block that implements the SMTP protocol. It is responsible for both sending and receiving mes- sages. When the destination has been reached, the MTA at the end host sends the message to the MDA. Examples of MTAs are sendmail, postfix, qmail and Microsoft's Exchange Server. • MDA - Mail Delivery Agent.

A BotNet consists by means of the IRC protocol. typically of about 20,000 PCs. It is guessed, that worldwide 50 mio PCs Source: "Threat Update: Botnets" by Lukas Feiler are available through BotNets Current Filter Approaches (1) .... Sample: port-87-234-35-12.static.qsc.de; p50805008.dip.t-dialin.net • Rejection during TCP connection phase; in particular DNS lookups: • Legitimate senders have to a have a A-Record maybe bad for dial-in users • Legitmate senders have to have a MX Record for the domain common practice for most of the cable net provider • Qualified senders have additional DomainKeys/SPF in place still not common; only for big players; a lot of overhead • RBL and OpenRelay lookups (bye, bye ORDB) may be poisend (requires additional whitelists) more-or-less static IPs only Ä Since BotNet PCs connect typically through cable nets/DSL (see above: QSC, t-online) those means don't help much Current Filter Approaches (2) ....
