Solution**:
From the description, we can see this challenge is about the series *Mr. Robot*. When E Corp is attacked by fsociety, Elliot finds a suspicious DAT file during his attempt to stop the DDoS attack.
During the Ferris wheel scene in Coney Island, Mr. Robot shows the IP address of Terry Colby on paper and asks Elliot to add his IP address into that DAT file.
