Curio Vendor Moogles All Gone...

This specific exploit couldn't be accessed vanilla, and had a hard limit on how much money you can extract by programmatically buying -> zoning -> selling, less than 10k gil per full character (inventory+sack+case+satchel) per zone. This made it a very low impact exploit. Still free infinite gil, but the rate at which it's created is minor, and it's evident that they preferred to spend dev time on more impactful things.

FFXI is clearly receiving more funding and dev time than it has received in a long time, thus it makes sense that they finally have the dev time for smaller things.

That, or the exploit they fixed was a different one, significantly more impactful than what Byrth explained in his post.

EDIT: I misremembered how much monies it was

It was ~700 gil profit per max potion and 320 max potions per zone, so it should have been about 220k/zone, right?

Max Potions have been on the NPC for ages and this vulnerability has been there the whole time, so my guess is that they only addressed it because someone was programmatically exploiting it.

Potions, that’s what it was. I remember now being in the medecine as that’s the only menu I really interacted with at the moogle. I don’t use addon, so not sure the difference but bought some and sold some many days later in adoulin and noticed the difference, but it wasn’t this bad.

There’s more out there, SE should offer a bug bounty, even if it’s just a title

Does packet injecting the sale to guild npc bypass limits?
