ThiefNet is a website that the Cooper Gang uses to sell their stolen loot for coins, and then use those coins to buy new power-ups to use in the field. It also has a chat room in which Bentley met Penelope and Dimitri Lousteau contacted the gang for help with obtaining his grandfather's scuba gear.
Sly 2: Band of ThievesEdit
First introduced after completing the mission "Bug Dimitri's Office," this in-game website allows you to buy a vast amount of power-ups. When you pickpocket loot from a guard, you can go back to your Safehouse and sell that treasure for a set amount of coins.
Sly 3: Honor Among ThievesEdit
In Sly 3: Honor Among Thieves, ThiefNet returned with several other features in the game. Loot is now immediately sold upon stealing, so the "Sell" tab has been removed. There is also a chat room which Bentley used to contact with Penelope.
Sly Cooper: Thieves in TimeEdit
ThiefNet also appears in Sly Cooper: Thieves in Time. In addition to new power-ups, the user interface is noticeably different. Power-ups can be bought for all members of the Cooper Gang, including Carmelita Fox. Unlike in previous games, buying power-ups is done with a single press, and power-ups remain displayed on the list after purchase. The version numbers of Bentley's hacking tools—System Cracker, Alter Ego and Spark Runner—are shown on the left side of the screen.
