Email address as identity

A few months ago I was talking about different mailbox tools and mentioned email addresses are the keys to our online identity. They are, email addresses are the magic key that authenticates us and opens access to different accounts.
The bad guys know this too. The Justice department recently announced a plea deal related to compromised email accounts. The individual in question gained access to faculty, staff and student email accounts. They then used access to these accounts to access Facebook, iCloud, Google, LinkedIn and Yahoo accounts.

Mediapost published an article this week referencing a survey performed at this year’s BlackHat conference.

Of 250 hackers polled, 32% said that accessing privileged accounts was the easiest and fastest way to get at sensitive data.
The second most effective route to data, cited by 27%, was access to user email accounts.

Email accounts are the keys to the kingdom. Protecting them is a vital part of protecting yourself online.

Compromises and phishing and email

Earlier this month, Sendgrid reported that a customer account was compromised and used for phishing. At the time Sendgrid thought that it was only a single compromise. However, they did undertake a full investigation to make sure that their systems were secure.
Today they released more information about the compromise. It wasn’t simply a customer account, a Sendgrid employee’s credentials were hacked. These credentials allowed the criminals to access customer data, and mailing lists. Sendgrid has a blog post listing things customers should do and describing the changes they’re making to their systems.
Last month it was Mandrill. Today it’s Sendgrid. It could be anyone tomorrow.
Security is hard, there’s no question about it. Users have to have access. Data has to be transferred. Every user, every API, every open port is a way for a bad actor to attempt access.
While it wasn’t said directly in the Sendgrid post, it’s highly likely that the employee compromise was through email. Most compromises go back to a phish or virus email that lets the attacker access the recipient’s computer. Users must be ever vigilant.
We, the email industry, haven’t made it easy for users to be vigilant. Just this weekend my best friend contacted me asking if the email she received from her bank was a phishing email. She’s smart and she’s vigilant, and she still called the number in the email and started the process without verifying that it was really from the bank. She hung up in the transaction and then contacted me to verify the email.
She sent me headers, and there was a valid DMARC record. But, before I could tell her it wasn’t a phishing email, I had to go check the whois record for the domain in question to make sure it was the bank. It could have been a DMARC authenticated email, but not from the bank. The whois records did check out, and the mail got the all clear.
There’s no way normal people can do all this checking on every email. I can’t do it, I rely on my tagged addresses to verify the mail is legitimate. If the mail comes into an address I didn’t give the sender, then it’s not legitimate – no matter what DMARC or any other type of authentication tells me. But most people don’t have access to tagged or disposable addresses.
I don’t know what the answers are. We really can’t expect people to always be vigilant and not fall for phishing. We’re just not all present and vigilant every minute of every day.
For all of you who are going to tell me that every domain should just publish a p=reject statement I’ll point out DMARC doesn’t solve the phishing problem. As many of us predicted, phishers just move to cousin and look alike domains. DMARC may protect citi.com, but citimarketingemail.com or citi.phisher.com isn’t.
We’ve got to do better, though. We’ve got to protect our own data and our customer’s data better. Email is the gateway and that means that ESPs, with their good reputations and authentication, are prime targets for criminals.

Post-mortem on the Spamhaus DOS

There’s been a ton of press over the last week on the denial of service attack on Spamhaus. A lot of it has been overly excited and exaggerated, probably in an effort to generate clicks and ad revenue at the relevant websites. But we’re starting to see the security and network experts talk about the attack, it’s effects and what it tells us about future attacks.
I posted an analysis from the ISC yesterday. They had some useful information about the attack and about what everyone should be doing to stop from contributing to future attacks (close your open DNS resolver). The nice thing about this article is that it looked at the attack from the point of view of network health and security.
Today another article was published in TechWeekEurope that said many of the same things that the ISC article did about the size and impact of the attacks.
What’s the takeaway from this?

The Cyber and The Security

Cybersecurity has been on my mind lately. There is a lot of bad stuff going on, from giant dDOS attacks, to subscription bombing, to the ongoing low level harassment that some people have to deal with on a daily basis. I’ve written a lot about how I think marketers are going to have to step up and stop being a conduit for abuse. I do believe this. There are a lot of different issues to discuss but there are also many, many different stake holders in the issue of cybersecurity.
I’ve been on multiple calls with different groups over the last few weeks discussing the implications of the subscription attack and how it was carried out. The majority of my focus is email and how to protect senders from becoming a conduit for abuse. Other folks participating on the call are looking at what abuse is out there and how to stop it or minimize it.
One thing that came up on a recent call is that the bulk of dDOS traffic that took Brian Krebs’ website down was from various Internet of Things devices. Security cameras, DVD players, televisions, lightbulbs and other connected devices were part of the problem. It’s a huge issue, and one that cannot simply be mitigated by just ISPs and providers. But convincing individuals to secure their lightbulbs can be a challenge, we can’t even protect their computers completely. Convincing companies to stop providing default usernames and passwords or using the same keys for every device is another challenge.
These are big issues that we’re going to have to deal with.
Last night, with 100 million of my virtual friends and a small group of local ones, I watched the first Presidential debate. Part of the debate was about cyber security. To misquote Vice President Biden, “Cybersecurity is a big freaking deal.” We have nation states, and groups with the resources of nation states, conducting covert operations online. We have hacking, compromises, bonnets and other malicious activity occurring every, single day. And, the more complex the site and the more users it has the more likely it is to be compromised. Cybersecurity is a critical part of national security and our own individual security. We must take it seriously and we must address it.
Now, I’ll be honestI don’t think there is a solution to the problem. I think, though, that there are hundreds of things we can do as individuals, as companies, as nations, as volunteer organizations, as NGOs and as coalitions to solve different parts of the problem. We all need to think about what it is and who’s doing the bad stuff.
It’s common to think of hackers as lonely boys in basements who have too much time and too little to do. Back in the ancient days of the spam wars some folks referred to them as “chickenboners“: beer drinking rednecks who ate fried chicken and threw the bones on the floors of their trailers. The reality even then, though, was that many spammers ran businesses and made a lot of money. Admittedly, the descriptions of how the business was run are cringe inducing and full of illegal activity.
Now, much of the hacking is actually organized crime outside the US. This makes it hard to address successfully through legal channels.
It’s all very complicated. But I think we can agree security is a big deal. We are all part of the solution, by securing our sites and our personal devices. We’re also part of the solution by paying attention to the larger issues and events going on around us.
