LivingSocial, the daily deals site owned in part by Amazon, has suffered a massive cyber-attack on its computer systems, which an email — just sent to employees and obtained by AllThingsD.com — said resulted in “unauthorized access to some customer data from our servers.”

The breach has impacted 50 million customers of the Washington, D.C.-based company, who will now be required to reset their passwords. All of LivingSocial’s countries across the world appear to have been affected, except in Thailand, Malaysia, Indonesia and the Philippines, as LivingSocial units Ticketmonster and Ensogo there were on separate systems.

One positive note in a not-so-positive situation: The email sent to employees and customers noted that neither customer credit card nor merchant financial information was accessed in the cyberattack.

This is the latest big data breach in the consumer Internet space, which has seen troublesome incursions into some high-profile companies recently, including Zappos, LinkedIn and Evernote.

When asked for comment on the email, a LivingSocial PR spokesman confirmed the attack and that 50 million customers were impacted.
