https://minecraft.fandom.com/wiki/Piglin_Brute

Piglin brutes attack players, wither skeletons, and withers within 16 blocks and are not distracted by golden items or blocks. They also attack any mob that attacks any piglin, or piglin brute, either by accident or purposefully. Examples include retaliation for attacks by snow golems and iron golems. Other mobs that accidentally shoot another piglin or piglin brute cause the piglin brute to become hostile toward that mob.
