Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn’t provided any information as of yet as to what is going on.
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 is, through to complaints that we’re not pointing out that some ESPs actually are secure. Some people have even provided counter examples of how simple it is to compromise any company, so why are we picking on ESPs.
Security is a problem any company faces. Some industries are bigger targets than others, and ESPs have really jumped up the target list. ESPs are getting lists stolen. ESPs are getting reputations stolen.
There’s one ESP I know for a fact that has lost multiple customer lists 3 times. Three companies I get email from are hosted there. When all three of those tagged addresses started getting spam, the only logical assumption was that the ESP was compromised. Again. Those are companies I want to hear from, though, and I changed addresses on their sites after every breach. What’s distressing, though, is the total lack of response from either the customer or the ESP to my notices about the breaches. To be fair, the problem seems to have stopped more recently.
Silence and refusal to address an issue is a big problem. An address I gave a company on the Only Influencers list was stolen (I’m not going to say leaked because I actually trust them to not have violated their privacy policy) sometime back in early 2011. I didn’t notice right away because my spam filters were catching the mail, but eventually the spammers managed to get one into my inbox. When I saw it, I started checking and realized that address had been compromised a long time ago. I notified the company, with as much history of the address as I could. I ended my message with:
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.
And that problem is security.
Much of what marketing does is build profiles of customers by collecting huge amounts of data on every customer. That data collection is facilitated by compliant customers that provide all sorts of personal data just because they’re politely asked by a retail clerk.
There will always be people who comply with data requests, but I expect more customers to be wary of sharing information at the register.
I’m not the only one, a recent NY Times blog post from one of their security researchers: Stop asking me for my email address. She discusses how much information companies ask for and how complacently consumers hand it over without asking about security.
