So, what exactly do you think would be a proper reaction here?
Hisbollah is de facto a state actor in Lebanon. Lebanon is doing nothing against a group whose declared goal is the destruction of Israel, including shooting unguided rockets into civilian areas.
Now, how would you address that? Unless you have any idea how else to solve this, you’re simply talking out of your ass.
By tracking who sent what to whom?
If you know the phone number of a Hisbollah member and they send messages to a set of pagers, these are likely Hisbollah pagers. If you do that to several phone numbers, you get a pretty comprehensive list of members. You don’t need to know, where exactly they are. That’s simply not relevant.
And again: if it’s a supply chain attack, you don’t even need these contacts. Just a single entry point into the supply chain of the organization.
