Collecting Cybercrime Data: Can Signal Spam Be a Piece of the Puzzle?

The gathering of coherent data on cybercrime is a problem most countries haven't found a solution for. So far. In 2011 it is a well known fact that spam, cybercrime and botnets are all interrelated. The French database Signal Spam may be a significant part of the solution to gather, analyse and distribute data on spam, phishing, cybercrimes and botnets, but also be a forum in which commercial mass e-mail senders and ISPs can work on trust. more

Facebook’s New Messaging Platform

On Monday, Facebook announced that they were introducing a new messaging platform. Facebook is careful to point out that this is not a replacement for email; it is not email, so they claim. So what is it? This messaging platform is basically a way to talk to people outside of Facebook from Facebook... Essentially, independent of the platform, you can still use the feature. It's kind of like everything Java promised in the 1990's -- it runs on Windows, the Mac or Unix. more

Why It Doesn’t Matter That the Virginia Anti-Spam Law was Struck Down

If the headlines are to be believed, spam is now entirely legal in Virginia and anyone can send whatever they want without any fear of reprisal, ever. Looking beyond the headlines, it appears that the Virginia Supreme Court's ruling in AOL's case against formerly convicted spammer Jeremy Jaynes declares that the Virginia anti-spam law violates the Constitutional protection of anonymous speech, and thus is null and void. more

Reputation and “The Cloud”

As Reddit recently learned it's not a great idea to use the Amazon EC2 cloud to host mailservers. There are a number of reasons for this, most of them related to the reputation of mail coming from EC2 servers. When you're using machines in the cloud, changing IP addresses is as simple as initializing a new server. Spammers discovered this almost as soon as the EC2 cloud became public. more

Email Vendors: Time to Build in DMARC

DMARC is extremely useful, yet I've heard some vendors are putting their implementations on hold because of the IETF DMARC working group. You really shouldn't wait though -- it's been in wide use for nearly three years, enterprises are looking at DMARC for B2B traffic, and the working group charter is limited in it's scope for changes. Let's compare this to a similar situation in the past. more

The Security Problem with HTML Email

Purists have long objected to HTML email on aesthetic grounds. On functional grounds, it tempts too many sites to put essential content in embedded (or worse yet, remote) images, thus making the messages not findable via search. For these reasons, among others, Matt Blaze remarked that "I've long thought HTML email is the work of the devil". But there are inherent security problems, too (and that, of course, is some of what Matt was referring to). Why? more

Logjam, Openssl and Email Deliverability

RHEL6/Centos6 (and presumably RHEL7/Centos7) machines with the latest openssl packages now refuse SSL connections with DH keys shorter than 768 bits. Consider RHEL6 sendmail operating as a client, sending mail out to a target server. If the target server advertises STARTTLS, sendmail will try to negotiate a secure connection. This negotiation uses openssl, which will now refuse to connect to mail servers that have 512 bit DH keys. The maillog will contain entries with "reject=403 4.7.0 TLS handshake failed". more

AOL Has a Security Hole, and It’s Our Problem

Two weeks ago I wrote about Yahoo's unfortunate mail security actions. Now it's AOL's turn, and the story, as best as I can piece it together, is not pretty. Yahoo used an emerging system called DMARC, which was intended to fight phishing of often forged domains like paypal.com. A domain owner can publish a DMARC "reject" policy which, oversimplifying a little, tells the world that if mail with their name on the 'From:' line didn't come from their servers, it's not from them so you should reject it. more

Deliverability Emergencies from the ISP Side of the Desk

I recently read an interesting blog post over at Word to the Wise, about Delivery Emergencies. Laura Atkins makes the point that many email emergencies are a result of poor planning, or an error on the part of the sender... Fortunately, most people grow out of their college fraternity phase, and the same applies to most email senders. As folks become aware of industry standards and best common practices, they adapt their mailing paradigms to what is expected of them by receivers, and recipients. more

Dave Crocker and John Levine Discuss Current Dealings With Spam (Video)

During the M3AAWG meeting in Brussels earlier this year, Dave Crocker and John Levine were asked to step into an impromptu video studio and talk about how email has changed over the past several decades and whether we are any closer to resolving the spam problem. more

Phishers Increasingly Targeting SaaS and Webmail Services, APWG Reports

According to the latest report from Anti-Phishing Working Group (APWG) while the total number of conventional, spam-based phishing campaigns declined in 2018, users of software-as-a-service (SaaS) systems and webmail services are increasingly targeted. more

Remembering the Good Times

The most effective early email-borne viruses didn't need botnets. They didn't change your computer settings, or steal your login credentials. And they somehow convinced regular users to help them spread. The first warnings about the Good Times virus began to appear in November of 1994, and by December the warnings were seen all over as people did what the warning said, and forwarded it to all their friends. There was another outbreak the following March... more

Facebook and PGP

Facebook just announced support for PGP, an encrypted email standard, for email from them to you. It's an interesting move on many levels, albeit one that raises some interesting questions. The answers, and Facebook's possible follow-on moves, are even more interesting. The first question, of course, is why Facebook has done this. It will only appeal to a very small minority of users. Using encrypted email is not easy. more

Privacy Rules to Change in the EU, But What If ...?

In a presentation EU Commissioner Viviane Reding gave a preview of the new Privacy regulation her DG is preparing. As she states, privacy rules need to be brought up to date and harmonized. With all 27 member states having the same rules and tools to enforce, a company only will deal with one privacy commissioner... So, what if we, for the sake of this blog, take this initiative towards spam and cyber crime. What would this do to spam enforcement? more

Implementing Natural Language Processing in Your SMB Organization: Now or Never!

If you have already adopted AI in your small or mid-size organization, congratulations. If not, the urgency of adopting should be a top priority. You will become a laggard and most likely obsolete given the supercycle of innovation we are currently in. Implementing AI is quite different from other organization-wide strategies because it involves highly specific characteristics and expert resource pools that SMBs might not be able to access. more
