Handling unwanted email Almost entirely based on a presentation by Brian Candler What are the main sources of junk email? · Spam Unsolicited, bulk email Often fraudulent ± penis enlargement, lottery scams, close relatives of African presidents, etc. Low response rate => high volume sent · Viruses, Trojan horses Infected machine sends out mails without the owner 's knowledge · Malicious bounces These are called ªcollateral spamº or ªJoe-jobsº Junk mail is sent with forged MAIL FROM Accepted by some intermediate MTA, but later it bounces Bounces go to innocent third party 1 What are the costs? · Important messages can be accidentally discarded The more junk, the higher the risk · Wasted time Deleting junk Setting up and maintaining ®lters Checking discarded mail for false positives · Wasted bandwidth and disk space Especially for users on modems Viruses and spam attachments can be large · Annoyance, offence, even fraud There are no easy answers! 2 Where can you ®lter? · At the end-user hosts ✓ Each client has full control and customization ✓ Distributes the processing cost ✗ Client must still download each message · On the ISP's mail server ✓ Easier for users ✓ Sometimes can be rejected before receiving the body ✓ Saves disk space on the server ✗ Hard to make ¯exible for users to customize The Joe-job problem · Don't accept a message and then bounce it later If its sender is forged, we are creating a Joe-job · Much better to reject at RCPT TO or DATA stages A real MTA sender will create a bounce Spamware will ignore the rejection · For -
DMARC — Defeating E-Mail Abuse
CERT-EU Security Whitepaper 17-001 DMARC — Defeating E-Mail Abuse Christos Koutroumpas ver. 1.3 February 9, 2017 TLP: WHITE 1 Preface E-mail is one of the most valuable and broadly used means of communication and most orga- nizations strongly depend on it. The Simple Mail Transport Protocol (SMTP) – the Internet’s underlying email protocol – was adopted in the eighties and is still in use after 35 years. When it was designed, the need for security was not so obvious, and therefore security was not incor- porated in the design of this protocol. As a result, the protocol is susceptible to a wide range of attacks. Spear-phishing campaigns in particular can be more successful by spoofing (altering) the originator e-mail address to imper- sonate a trusted or trustworthy organization or person. This can lead to luring the recipient into giving away credentials or infecting his/her computer by executing malware delivered through the e-mail. While raising user awareness on how to avoid e-mail fraud is recommended, the Verizon Data Breach Investigations Report indicates that more needs to be done. The DBIR report reveals that 30% of all phishing e-mail messages were opened by the recipients and with 12% clicked on the content and executed malicious code. The median time for the first user of a phishing campaign to open the malicious email is 1 minute, 40 seconds. The median time to the first click on the attachment was 3 minutes, 45 seconds. These statistics highlight the risk for an organization on the receiving end of spear-phishing e-mails. -

You can read more of Brian’s content here on the SocketLabs website. ©2019 SocketLabs 2 Executive The Edward Snowden leaks of 2013 opened many peoples’ eyes to the fact that mass surveillance was possible by Overview intercepting and spying on email transmissions. Today, compromised systems, database thefts, and technology breaches remain common fixtures in news feeds around the world. As a natural response, the technology industry is rabidly focused on improving the security and encryption of communications across all platforms. Since those early days of enlightenment, industry experts have discussed and attempted a variety of new strategies to combat “pervasive monitoring” of email channels. While pervasive monitoring assaults can take many forms, the most prominent forms of interference were man-in-the-middle (MitM) attacks. -
