Ashley Madison Compromise

Last month Brian Krebs reported that the Ashley Madison database was compromised. Ashley Madison is a dating site that targets married folks who are looking to have affairs. Needless to say, there is a lot of risk for users if their data is found on the released data. Today what is supposedly the Ashley Madison data was released.
The release of this data can have some significant impacts on the site members. Of course there’s the problem of credit card numbers being stolen, but that’s something most of us have to deal with on a regular basis. But there can also be significant relationship repercussions if/when a spouse discovers that their partner has registered on a site to have affairs.
When I first heard of the compromise I wondered if they had my data. You see, they have one of my spamtraps on their unsubscribe list. It just so happened that I visited an unsubscribe link, hosted by Ashley Madison (http://unsub.ashleymadison.com/?ref=2). This was during the time when I decided to unsubscribe from all the spam coming into one of my spamtraps. Is my email address going to be a part of this data dump? If my email address is there, what name do they have associated with it? This is the trap that gets mail addressed to multiple other people. Maybe it’s my email address but their name. Are they at risk for relationship problems or legal problems due to my attempt to unsubscribe?
Of course, Ashley Madison had no incentive to make sure their data was correct. In fact, they were sued for faking data to entice paying members. How much of the released data is false and will there be real harm due to that?
I expect in the next few days someone (or multiple someones) will put up a website where those of us who are curious can search the data. I just hope that people realize how much of the data is likely to be false. Even Arstechnica cautions readers from jumping to conclusions.

Assuming the download turns out to be authentic, people should remember that it was possible for anyone to create an account using the name and e-mail address of other individuals. That means an entry for a given individual doesn’t automatically prove the person was behind it.

Still. There are probably a lot of people worried about this release of data.

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 to not use a windows machine to browse the web was over the top and paranoid. It may be, but drive by malware attacks are increasing. Visiting big sites may not be enough to protect you, as hackers are compromising sites and installing malware to infect visitors to those sites. Some ad networks have also been used to spread malware.
Criminals have even figured out how to install malware on a machine from email, without the recipient having to click or open attachments.
Avoiding the internet from a machine running Windows is a security recommendation I don’t expect many people to follow, but I do not think security and anti-virus software is enough to protect people from all of the exploits out there.
Of course, there are a lot of reasons that one might be forced to use a particular browser or operating system. For instance, I was on the phone with my bank just today to ask if they supported Safari. They say they do, but there are some things that just don’t work. The customer service rep said that they recommend Internet Explorer to all their users. She then suggested I switch browsers. No thanks, I’ll deal with the broken website.
Compromises are a major threat, and criminals are spending a lot of time and money on creating ways to get past current security. No longer is “not clicking on malware” enough to protect users. When a security clearinghouse is compromised and used as a vector for a targeted attack against Google, none of us are safe. When a security company is compromised, none of us are safe.
I realize my recommendation to avoid browsing the web on a Windows based machine is more wishful thinking than practical. I also know that other browsers and operating systems will be targeted if enough people move away from currently vulnerable operating systems. And I know that a simple, offhand suggestion won’t fix the problem.
As someone who’s been online long enough to see the original Green Card spam I know that online dangers evolve. But I can’t help thinking that most of us aren’t taking the current threats seriously enough.

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.

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 me that it’s not always new companies that don’t think about abuse potential before launching services.
