New Spam?

Here's an email I received today. It reports I've been signed up for a mailing list and asks me to unsubscribe if I didn't sign up for the mailing list. Legitimate mailing lists tell you to ignore the message and do nothing if you didn't sign up. It looks like the mailing agent belongs to h24-71-223-11, who I guessed was 24.71.223.11. That IP resolves to h24-71-223-11.cg.shawcable.net. That machine is offering a mail server on port 25:

220 pd2mi3so.prod.shaw.ca -- Server ESMTP (iPlanet Messaging Server 5.2 HotFix1.18 (built Jul 28 2003))

However, that mail server doesn't allow mail relay.

I think the system which originated the email is (h0000864f50cd.ne.client2.attbi.com [24.62.13.114]).

A message from Yahoo! Groups wouldn't originate from a home AT&T user. The mailer agent is interesting too -- "Synapse, which is a synchronous TCP/IP library for Delphi, Kylix,
FreePascal, and C++ Builder," according to my friend John Ward. He also says "this was some tool written to be a dedicated, non-threading mass mailer due to its synchronious nature, probably a command line tool, written for either Windows or Linux."

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Image
Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...

  I've completed the TaoSecurity Blog book series . The new book is  The Best of TaoSecurity Blog, Volume 4: Beyond the Blog with Articles, Testimony, and Scholarship .  It's available now for Kindle , and I'm working on the print edition.  I'm running a 50% off promo on Volumes 1-3 on Kindle through midnight 20 April. Take advantage before the prices go back up. I described the new title thus: Go beyond TaoSecurity Blog with this new volume from author Richard Bejtlich. In the first three volumes of the series, Mr. Bejtlich selected and republished the very best entries from 18 years of writing and over 18 million blog views, along with commentaries and additional material.  In this title, Mr. Bejtlich collects material that has not been published elsewhere, including articles that are no longer available or are stored in assorted digital or physical archives. Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technica...
