Port 6379 is the default port for Redis, an in-memory data store.

Where 6379 fits
Why 6379 is special
Redis was designed for trusted networks and historically shipped with no authentication, so an exposed 6379 was for years a direct route into a server rather than merely a data leak. Later versions bind to localhost by default, which is a fix at the level of the default rather than the protocol.

6 × 1,000 + 3 × 100 + 7 × 10 + 9 × 1 = 6,379. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Redis was built for use inside a trusted network and long shipped without authentication, so an exposed 6379 offered command execution rather than merely data. Later versions bind to localhost by default — a fix at the level of the default rather than the protocol.
