Following their major database breach, Zappos leadership is doing the right thing by what seems to be quickly and clearly communicating what data was accessed and what was not - there are no unexplained delays or confusion on their part about the event. It's like another Aurora moment in my book, when Google extraordinarily opened up about their breach while the other 30-odd Aurora-breached major corporations did the opposite, aggressively maintaining NDA's to hide their Aurora incidents and hide their heads in the sand. Zappos reset 24 million customers' passwords and emailed all of them about the problem last night.

It's the end of 2011 as we know it, and Microsoft feels fine finishing out the year with a handful of out-of-band holiday patches. This round is important not because the vulnerabilities directly impact massive numbers of customers and their online behavior on Windows laptops, tablets, and workstations, but because ASP.NET maintains vulnerable code enabling easy DoS of hosting websites, authentication bypass techniques, and stealth redirections to other websites (most dangerously those sites hosting phish and hosting client side exploits and spyware). All of this could curdle your eggnog in the coldest of weather.

Several Eastern European banks have started notifying their customers in the beginning of last week that their cards have been blocked and will be replaced with new ones. Most of the banks did not give out any more details about what happened, and in many cases even failed to notify their customers prior to actually blocking their cards. Is it just another day in the payment processing business? Based on the rushed response from banks and the lack of information surrounding the case, I would say no.
It all started one week ago after the state-owned Romanian bank CEC Bank blocked ~17,000 cards in response to a security breach at one of VISA’s European payment processor.
The reaction of other banks followed soon. The Romanian branch of ING Bank also confirmed to have blocked compromised cards, but didn’t put out a number. They say they’ve only blocked a few cards, but are closely monitoring the situation.
A few days later, Serbian banks also started blocking thousands of cards for security reasons. Raiffeisen Bank, Komercijalna and Societe Generale confirm they have been informed by VISA about some of their customer’s cards being compromised. Very similar to what happened in Romania.
Rumors indicate the European branch of an electronic payment services provider, Euronet Worlwide, to be the source of this breach. This information has been going around Romanian business media (1, 2) – and though it hasn’t been confirmed officially, it would explain why customers from different banks in different countries were affected.
It’s very hard to assess the severity of this security breach, as the banks’ reaction to these events was very mixed. Some banks proceeded immediately to blocking and replacing all affected cads, while others decided to monitor the situation more closely.
Currently, it’s very hard to get a full picture of what is going on, but as it usually happens, these are unlikely to be isolated incidents. Actually, these stories could be just the tip of the iceberg. If you have recently received such a notification from your bank, we’d like to hear from you, especially if it’s outside Serbia and Romania.
Meanwhile, make sure to follow these 3 basic steps to make sure you don’t become a victim of credit card fraud:
