Preheat oven to 350°F and line a baking sheet with parchment paper.
Arrange the beef rib fingers onto the prepared baking sheet, making sure that each piece is not touching.
In a small bowl, mix together the vinegar, Worcestershire sauce, and white sugar until combined.
Brush the mixture over the beef rib fingers.
In another small bowl, mix together the dry rub ingredients until combined. Sprinkle the dry rub evenly over the beef rib fingers.
Bake in preheated oven for 15-20 minutes or until cooked through and golden brown on top.
Remove from oven and let cool slightly before serving.
