There are other stacks around that have NSS or external DLLs in it, like bp-d346618c-faa1-464a-8dce-fccb32150205 or bp-4b088253-ca56-47a1-b826-f108c2150205 but all those stacks seem to come from HTTP connections.

At least some part of the URLs seem to point to Indonesian sites so that might have some connection:
