臧聲zāng — to stash, hold; gives the sound (the root behind 藏, 臟)
A cowrie (貝, goods of value) plus 臧 (zāng) for the sound — wealth that was taken and stashed: 贓物 (stolen goods), 貪贓 (graft), 分贓 (split the loot). 臧 is the root that also gave 藏 (to store) and 臟 (the organs tucked inside); here it names what is held wrongly.
