Online Heists for GTA V are one of the long awaited features of the game. Fans have been patient with Rockstar, despite few details about the modes. Earlier this year, Rockstar had promised information about the heists feature, and recently had to issue an apology due to being unable to make good on that promise.
Leave it to the GTA Online Community to discover new details. Apparently, a group of YouTubers have discovered files in the GTA V source code that may detail the GTA Online Heists.
The alleged heists details list a number of different missions. These include a Prison Van Rescue, Drop off hooker, Funeral, Territory Takeover, Gang Initiation, Cop Territory, Ornate Bank Heist, and an FIB Heist.
Numerous YouTube channels have done a break down on the leaked data. You can find an especially concise one here. Though the original leak comes from YouTuber, DomisLive. Both outline what GTA V Online fans could potentially expect when Rockstar finally releases Online Heists for the game.
While this is far from actual confirmation from Rockstar themselves, the information on this page and in the YouTube videos should be taken with a grain of salt.
