Received dust to a btc address that i Iast used in 2019

Hey, I received bitcoin dust on an address i last used in 2019, when moving funds to change from the hold format to the bc1 format. the address had 1 transaction sometimes in 2019 for this purpose and now i received a second one in april from this address: bc1qls0rn38632pterjj444sdnqmqp6cljc667l6us

Looking at block explorer it seems like this wallet is doing thousands of theses dust transactions. Now I imagine that it is some kind of tracking for future attack possibly? This address of mine hold what many would call a significant amount of btc. What can I do to mitigate any tracking or attack vector? Thanks.
