Users who logged on to the website for Dublin City’s light-rail service on Thursday morning received a message that said: “You are hacked”

The message hackers posted to Luas.ie

“some time ago I wrote that you have serious security holes," the hackers posted, “you didn't reply"

The hackers also went on to demand a ransom: "You must pay 1 bitcoin in 5 days otherwise I will publish all data and send emails to your users."

Currently, one Bitcoin is worth about $3,844.

On Twitter, Luas said that their IT department took the site offline in order to correct the issue, which could take at least a day.

Luas representatives added that the website hack should not affect Luas service through Dublin City, and that users can still access information via social media and helplines.
