Suspicious unknown transactions???

Need some input on a .90cent deposit that I received this morning around 9am EST. It’s from an unknown wallet that had $1995.59 worth of USD and they sent the same .90cent deposit to another 1400 addresses. Why would someone send this small monetary transaction to this many random wallets? The transaction has been pending for hours now. If this transaction doesn’t clear soon would it affect me depositing funds into my wallet if it’s pending? Any help is appreciated
