We have decided to terminate the support for MtGox Legacy API early, after one of our user reported a hacking attempt on his MtGox account.
We believe it is unlikely that the password leak came from our platform, since even site admins need specific and global bot updates to get access to that data, which is stored encrypted and not sent to the client browser.
As the new API does not require your password, and can be limited to trading only, we thought it is a safer move to completely disable the legacy bot right now, and delete the related user data.
Existing legacy users were notified by email and invited to register a new bot for the most recent API.
In the mean time, we will be reviewing the site's security and let you know of any upgrades.
