People are your weakest link

Social engineering is a long standing way to compromise security. Chunkhost reports today that they discovered accounts being compromised through social engineering of Sendgrid support. While the compromise did not work it was a close call. The only thing that saved the targeted customers was their implementation of 2 factor authentication. We know many of […]

Target breach started from email

According to Brian Krebs the compromise of Target’s POS system probably originated with a phishing attack against one of Target’s vendors. This attack compromised credentials of the HVAC vendor and possibly allowed the hackers entrance into Target’s systems. Interestingly, Brian mentions Ariba, a company I’ve been forced to deal by a large customer of ours. […]

Michele Bachmann Announces She’s Done

U.S. Representative Michele Bachmann (R-Minnesota) announced today that she’s not going to seek re-election in 2014. Last time around, the race between her and Minnesota businessman Jim Graves was very close. Mr. Graves lost by a very narrow margin. Graves had already announced his intention to take on Ms. Bachmann again next year. As the news […]

Password security

Many of us have lots of accounts on various networking sites, but how much attention do we pay to password security? If you haven’t heard, someone managed to compromise the Associated Press’ twitter account today. Not only was the account compromised, but they put out a fake tweet claiming that there were explosions at the […]

Services, abuse and bears

A couple weeks ago I wrote a post about handling abuse complaints. As a bit of a throwaway I mentioned that new companies don’t always think about how their service can be abused before releasing it on the unsuspecting internet. Today’s blog post by Margot Romary at the Return Path In the Know blog reminds […]

Get a helmet

There’s been a lot of interesting reaction to Steve’s security post yesterday. A lot of people seem upset that we have pointed out one of the ways that ESPs may be getting compromised. Complaints range from the message being overly simplistic, through to complaints that we just don’t understand how much of an issue security […]

I know your customers’ passwords

Go to your ESP customer login page and use “View Source” to look at the HTML (under “Page” on Internet Explorer, “Tools->Web Developer” on Firefox, and “View” on Safari). Go on, I’ll wait. Search for the word autocomplete. If it says something like autocomplete=”off” then your web developers have already thought about this security issue. […]

Browsers, security and paranoia

MAAWG is coming up and lots of us are working on documents, and presentations. One of the recent discussions is what kind of security recommendations, if any, should we be making. I posted a list of things including “Don’t browse the web with a machine running Windows.” Another participant told me he thought my recommendation […]

Is any data safe?

Today another major retailer announced their customer files were compromised. This company had clearly implemented some security that kept hackers from getting too much information. Passwords were hashed and credit card numbers were kept on a separate server, which does signal that the company designed with security in mind. Nevertheless, personal information was compromised. Is […]

Are you ready for the next attack?

ESPs are under attack and being tested. But I’m not sure much progress in handling and responding to the attacks has been made since the Return Path warning or the Epsilon compromise. Last week a number of email marketers became aware that attacks against ESPs and senders were ongoing. The shock and surprise many people […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments
