Recently Ebay’s database has been compromised by a group of cyberhackers. This records as the second largest database breach in history with over 140 million users compromised.
We weak link in this cyberattack were the employees. The attackers were able to get access to Ebay employee credentials and were able to access the corporate network, which granted them access to the database.
Ebay and Paypal urged customers to change their password because the encrypted version of the password were leaked along with the customer’s names, dates of birth, addresses, and security questions.
Database is on sale
Now either the hacker or someone pretending to be him is selling the 140 million user database on pastebin. The hacker provided a 3,000 row extract from the database with names, addresses, phone numbers, and dates of birth as proof. However, Ebay denied that the extracted database was authentic. According to an Ebay spokesperson
“The published lists we have checked so far are not authentic eBay accounts.”
Security experts used the 3,000 row extract to try and identify and narrow down the source of the extract. Here are some of the offers on pastebin for the compromised database:

Ebay has confirmed that the database rows provided is not authentic but can we really trust that? Security experts are trying to narrow down and identify the source of the attack. One UK cyber security company – Digital Shadows – cross referenced the leaked data with Facebook and confirmed that the names are real, even if they might not have come from Ebay.
We need a third party to either confirm or deny that the 3000 rows did or did not come from Ebay. Ebay might deny the authenticity of the database but for all we know it could simply be a business move to minimize the severity of the situation.
The compromise of the 140 million user database is a serious issue from the perspective of identity theft. Even though Ebay is not putting importance on the data that was stolen, the consequences of the attack may be felt far ahead in the future.
This attack is the second largest of the type in history. Some customers are concerned about their information landing in the wrong hands:
I am concerned that not only have they lost my email, username and password, but according to their website the loss includes home address, phone number and date of birth. This is serious from an identity theft perspective
The only item that the hacker’s are missing is mother’s maiden name and then they gain sufficient information to impersonate an individual and deal with financial institutions.
While the password’s were also hacked in the attack they were encrypted and hashed so the real passwords did not show up. However, if the hacker’s obtain the private and public keys to the password they could potentially derypt the hashes and reveal the real passwords. The biggest problem with this is that many users use the same password for different accounts, so if the hackers know your password to Ebay they may be able to access your Facebook, Twitter, Bank Accounts, etc.
According to Ebay’s twitter:
So this time we got lucky and if you are an Ebay customer than you shouldn’t need to worry about your other accounts with the same password getting compromised. However, just to stay on the safe side I would change the passwords to your other accounts because we do not know what the cyber attackers are capable of.
