If the spam is actually being sent from the Google group, Google should
deal with it.
On the other hand, if it's just mail that cleverly spoofs the google
group as the sender, the originator's IP address should be somewhere in
the Received: headers, and it should be possible to detect the
difference between these and real Google groups email in a SpamAssassin
rule.
Or, if as you say elsewhere they all have a header like
> List-Unsubscribe: <mailto:googlegroups-manage+30218623922+unsubscribe at googlegroups.com>,
> <https://groups.google.com/group/azovwave2/subscribe>
You should be able to get that with a spamassassin rule like
header RULE_NAME List-Unsubscribe =~ /subscribe>$/
