I recently bought GTA V - got a good deal (£23.50) on Greenman Gaming for the PC 'Megalodon Edition' (comes with an $8,000,000 Shark Card). It's a Rockstar Social Club version, not Steam. All installed and registered fine, no issues at all. Began playing GTA V Online. Noticed I had $8,000,000 to spend in-game.
Five minutes later I got notification that not only had I just been 'paid' $500,000 for 'security services' (remember, I had only just started playing this game), but I then started receiving a huge cash transaction which continued for about five minutes. When it had stopped I checked my bank balance -
£42,500,000!
I have no idea how this happened - I have no cheats, no trainers, no mods, etc installed - just the vanilla game as it was installed by the official Rockstar launcher. I'm pretty sure I was the very fortunate beneficiary of a 'cash drop' by a hacker - apparently the game is riddled with them (and I later spotted in the live chat people asking for cash drops). I just happened to be in the right place at the right time.
I went out and immediately bought a $1,000,000 luxury penthouse apartment, two hi-end sports cars and the biggest luxury yacht available ($8,000,000 including helicopter). Then I saved my game.
$32million left in the bank. THUG LIFE!
