Berlin - The publishing house that issues Donald Duck and Mickey Mouse comic books in Germany alerted fans on Tuesday that its website had been hacked and data on thousands of users stolen, reported German media.

“Unfortunately we have to tell you that, as near as we can tell, a hacker attack Monday meant that data entered (at the site) has landed in the hands of unknown people,” noted the website of Lustigen Taschenbuch (LTB), or Funny Pocketbooks.

The paper reported that 24,000 users might have been affected. Data affected includes passwords and personal data. Users were urged via email to change their passwords, especially if they use the same password at other sites.

LTB has published more than 400 paperback anthologies of the adventures of the Disney characters since 1967. Fans used the website to discuss the comics and the characters. - Sapa-dpa
