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 our customers individually and personally, and are still careful about changing contact addresses and passwords. With larger customer bases, it’s vital that every person in the change follow security processes.

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 exhibited prompted my Spear Phishing post on Friday.
The first round of phishing went out on Wednesday, by Friday they were coming from a different ESP. Whether this was a compromised ESP customer or employee it doesn’t matter. ESPs should have reaction plans in place to deal with these threats.
It’s been months since the first attacks. This is more than enough time to have implemented some response to reports of attacks. Yet, many people I talked to last week had no idea what they should or could be doing to protect themselves and their customers.
Last time the attacks were publicly discussed I was frustrated with many of the “how to respond” posts because few of them seemed to address the real issue. People seemed to be pushing agendas that had nothing to do with actually fixing the security holes. There were lots of recommendations to sign all mail with DKIM, implement 2 factor authentication, deploy validation certificates on web properties, or adhere to sender’s best practices.
None of those recommendations actually addressed the gaping security hole: Humans.

Brian Krebs wins the Mary Litynski award

A little late, but I’ve been in sessions most of today. M3AAWG announced this morning that Brian Krebs won the 2014 Mary Litynski award. This award is given to people who work tirelessly to make the internet a better place.
I first had the pleasure of listening to Brian give the keynote address at a MAAWG conference many years ago. His ability to infiltrate some major spam operations and online forums for criminals is amazing. He’s also had retaliation attempts, including being SWATed and having heroin delivered to his house.
If you get a chance to hear Brian speak, I strongly encourage you to do so. His knowledge is outstanding and his speaking style is entertaining. I’ve learned a lot from Brian over the years and I’m pleased he won this award and that M3AAWG recognized his contribution to stopping abuse online.

First spam to Epsilon leaked address

This morning I received the first two spams to the address of mine that was compromised during the Epsilon compromise back in April. Actually, I received two of them. One was the “standard” Adobe phish email. The other was similar but referenced Limewire instead of Adobe.
