I'm curious of anyone else has seen such patterns and if they've
discovered any particularly negative results as a consequence of the
probes.

Yeah. It's a trojan.  Its goal in life is to search out open proxies and
report back to the author when it finds one.   It's called RingZero.

I've seen a new variant of this signature that includes 1080/tcp.  It may
be a new version, or it may be just someone manually looking for open proxies.
