Just noticed this under "Current travel information":
Current information concerning
www.lufthansa.com
Lufthansa recommends all customers with Lufthansa accounts to change their passwords as a precautionary measure, should they be used on other sites as well. Users who log in with their Miles & More number and PIN are not subject to this recommendation.
Not really much information in there, but usually these type of requests point to some breach of the integrity of the website...anybody has more information?
