I could be totally off beam with this, but this is giving me the same vibes as the weird Star of David mass graffiti in Paris a few years ago.
That was an overnight appearance of blue & white striped Stars of David sprayed on random buildings across Paris.
It caused alarm but had no clear meaning – so the public had to come up with their own meanings (pro-Israel, anti-Israel, identifying Jewish people though not on Jewish-occupied buildings...).
A Moldovan couple claimed to have been approached by someone who heard them speaking Russian and asked them to spray the graffiti for money. French intelligence services suspect it was a Russian dezinformatsiya operation to cause disruption for the sake of disruption.
Star of David graffiti in Paris - the Russian connection

Quoting sources in the investigation, Le Monde said the cut-price modus operandi - using poorly-paid proxy freelancers - was typical of today's Russian intelligence, which was hit hard by the expulsion of spies from Western capitals after the outbreak of the Ukraine war.
As for the purpose of Operation Star of David, like all dezinformatsiya it seems to have been to sow confusion and anxiety. The fact that the symbol could be either pro- or anti-Israeli made it all the more interesting: that way both sides would be suspicious.
