Earlier this week, Pokémon Go teased the discovery of a mystery item that has connections to Team Go Rocket, and an update has just been released.
Professor Willow explained that a mystery component was found after a Team Go Rocket Grunt dropped it following a Pokémon battle. While the origins and purpose of the mystery component remained unknown, Willow proposed that this device allowed Team Go Rocket to infiltrate PokeStops in Pokémon Go.

Here's the latest update on these mysterious items from Professor Willow on the official Pokémon Go blog:
"We're getting closer to finding another use for these Mysterious Components. I've been developing a prototype for something I call the Rocket Radar by combining several of the components together, but it's still not functioning as intended.
I believe that if I can create a functioning prototype of this Rocket Radar, we might be able to use Team GO Rocket's own technology to find out where their hideouts are. While it's relatively easy to find Team GO Rocket Grunts (the PokéStops they hack become noticeably discolored and have a glitch-like appearance), we've had a difficult time finding where the Team GO Rocket Leaders—or even Giovanni—are hiding.
These Mysterious Components hold the key to making this Rocket Radar work. I know we can uncover where the Team GO Rocket higher-ups are hiding. I need to rally our team leaders to dig further into this."

It seems Niantic is preparing for a special event or research task involving Team Go Rocket. Perhaps Niantic is waiting for the ongoing Halloween event to end on November 1 before moving forward with this possible Team Go Rocket task.
Pokémon Go players were first introduced to Team Go Rocket in July, and the threat was thought to be under control until files were found that revealed possible new boss trainers who have yet to make their official debut in the mobile game.
Currently, Team Go Rocket Grunts can be found in black PokeStops. These Grunts use Shadow Pokémon to battle trainers, and they are very powerful. Defeating a Grunt, however, leads to players having a chance to catch one of the Shadow Pokémon on the Grunt's team.
Here is the current list of Shadow Pokémon that can be caught:
- Bulbasaur
- Ivysaur
- Charmander
- Charmeleon
- Squirtle
- Wartortle
- Weedle line
- Rattata line
- Zubat line
