Every player of Wargaming.net's Wold of Tanks is asked to change their password as soon as possible; this is because PlaySpan, the system Wargaming uses to conduct real money transactions in this game, has been hacked.
This means that over two million account details have been leaked online, including email addresses, user IDs and encrypted passwords. A leak on credit card information has not been mentioned, yet, there is never enough security, so at least a password change should be done by users.
PlaySpan's response against this hack was to shut down the Marketplace and lock user accounts, until they've conducted an investigation.
"When PlaySpan detected the breach, we immediately shut down the hacker's access to our systems and took steps to protect our customers' PlaySpan accounts. We then commenced a comprehensive forensic analysis and are working with law enforcement to investigate the crime.
We sincerelyapologize for any frustration or invonvenience this incident has cause our customers. We know PlaySpan's business depends on consumer trust. Security is a top priority for us, and we are redoubling our efforts to strengthen PlaySpan's overallsystem security."
Since this situation occurred, Wargaming America has released an official statement as well
"Wargaming is aware of the recent security issue with PlaySpan, which affected user accounts associated with its Marketplace store, including user name, email addresses, and encrypted passwords. This affects World of Tanks players only if they used their Marketplace accounts to purchase PlaySpan Ultimate Game Cards through uPay. Wargaming urges players to change their user information and passwords if they are identical on both PlaySpan and on Wargaming.net/WorldofTanks.
Players who do not have common user information for both are at no security risk, and in addition, no financial data was compromised in the security breach.
Everyone at Wargaming apologizes for this inconvenience."
