Why do you think those peers are malicious? The blockchain is over 150 GB. Those peers are probably syncing the blockchain.
Bitcoin Core does not think those peers are malicious, otherwise it would have disconnected and banned them itself. It has its own ban criteria which is much more than just bandwidth usage and strange versions (the version isn't even a criteria). This criteria includes things like receiving invalid blocks and transactions, receiving a lot of malformed messages, etc. Downloading a lot of blocks is not evidence of malicious behavior.
