You can Hack Portals of any color to acquire items such as Resonators, XMP Bursters, and more. While you can hack any Portal, the quality of receiving items you receive depends on whether the Portal is neutral or controlled by one of the Factions. Friendly Portals yield the most inventory, so hack them often. Also, be warned: When you Hack Enemy Portals, they may attack you and reduce your XM reserves.
- Move towards a Portal till it’s within your action range.

- Select HACK
- And receive items from that Portal.
