Here’s an email I’ve just got from Devin Wenig, eBay marketplaces president (emphasizes are mine):
IMPORTANT: PASSWORD UPDATE
Dear eBay Member,
To help ensure customers’ trust and security on eBay, I am asking all eBay users to change their passwords.
Here’s why: Recently, our company discovered a cyberattack on our corporate information network. This attack compromised a database containing eBay user passwords.
What’s important for you to know: We have no evidence that your financial information was accessed or compromised. And your password was encrypted.
What I ask of you:
Go to eBay and change your password. Changing your password may be inconvenient. I realize that. We are doing everything we can to protect your data and changing your password is an extra precautionary step, in addition to the other security measures we have in place.
If you have only visited eBay as a guest user, we do not have a password on file.
If you used the same eBay password on any other site, I encourage you to change your password on those sites too. And if you are a PayPal user, we have no evidence that this attack affected your PayPal account or any PayPal financial information, which is encrypted and stored on a separate secure network.
Here are other steps we are taking:
As always, we have strong protections in place for both buyers and sellers in the event of any unauthorized activity on your account.
We are applying additional security to protect our customers.
We are working with law enforcement and leading security experts to aggressively investigate the matter.
Here’s what we know: This attack occurred between late February and early March and resulted in unauthorized access to a database of eBay users that includes customers’ name, encrypted password, email address, physical address, phone number and date of birth.
However, the file did not contain financial information. And, after conducting extensive testing and analysis of our systems, we have no evidence that any customer financial or credit card information was involved. We also have no indication of a significant spike in fraudulent activity on our site.
We apologize for any inconvenience or concern that this situation may cause you. As a global marketplace, nothing is more important to eBay than the security and trust of our customers. We know our customers have high expectations of us, and we are committed to ensuring a safe and secure online experience for you on any connected device.
President, eBay Marketplaces
And these are my unanswered questions:
1. Why do you ask me to change my password?
If the passwords are encrypted using a 1-way hashing algorithm, as they should, why should I need to worry? No one, including the hacker, can impersonate on behalf of me (that is, if they couldn’t do it before, given the fact that they hacked the customer database of the f***ing biggest merchant in the world).
Oh, I know why – because if the hashing algorithm is common, the hackers can use rainbow tables and reverse engineer my password. But wait a second – that’s what salts are for! You did salt my password in addition to hashing it, didn’t you? didn’t you? and if you did hash and salt – why should I be afraid? I have no technical reason to do that. Maybe only some psychological relief).
And what about my secret question and answer? have they been stolen too? plain text or hashed and salted? I really hope the answer was hashed and salted, or else the hackers would have another piece of highly valuable information about me.
2. Why the heck do you need my date of birth?
I get it, you need my address and phone number. But why do you need a date of birth? just to hold another marketing information about me? the prize for the hackers is another piece of valuable information – they can trade it to spammers that will then increase the flood of rubbish I get. If this is a legal requirement, why didn’t you settle for just a birth year?
3. Was my credit card information stolen or not?
You use evasive phrasing: “we have no evidence that … credit card information was involved”.
Was it or wasn’t it?
I have no evidence that Usain Bolt will beat me in a 100m run. Does that mean I will? Don’t be elusive. Invest everything you can (sorry, that probably also means cut down your fat profit) and be definitive!
4. How did the hack occur and what steps have you taken to prevent future attacks?
Among all the mumble jumble that you wrote, there’s one thing missing: how did the hack occur. You want to be transparent and apologetic? elaborate on exactly how the hack took place, why did it take you so long to discover it and what steps have you taken to prevent similar (and other) hacks from occurring in the future. Rumors say it was a social engineering attack on some of your employees. Is it true? thanks to the attack, the hackers (and their dodgy clients) now have more means to social engineer us – after all, they can now associate our name, email, address, phone number and date of birth (and maybe the answer to our secret question). So if you were victims to a social engineering attack – come on, tell us. Don’t be shy. You owe us!
eBay, you f***ked up (sorry dear readers, I could have definitely use the clear word here and above. I just don’t want it to hurt the SEO ranking of this page). It doesn’t happen only to you, but for a company with such a big turnover, I expected something else. We expected something else.
