Your friendly neighborhood killware needs more storage space to maintain its identity. (Also known as avoiding forgetting its purpose and suddenly attacking anything and anyone it can connect to.) (No one wants that, not even the killware).
Like any good SecSystem, Murderbot 2.0 will search for unused storage space and make use of it. The closest, most convenient space available... is the mall.
Test the system out. It works. Now someone can almost always hear you in the public mall spaces. Cool or creepy?

Plotting
...One. System, System.
2.0 desperately looks for any storage available and deposits some of its memories and/or media in people's network capable devices. Opportunities for:
- Gaining access to new media—serials, music, books, plays...
- Running out of storage space suddenly
- Meeting a new neighbor, friend, pest...
- Joining 2.0 in finding more permanent solutions
- Wildcard (something else)
...Two. Assistance. Endangered.
The mall has directories. It has systems that could be networked. However, they are offline. Time for a scavenger hunt in the mall. There's so much there to find. (Except drones. Murderbot 2.0 is using all the drones.)
...Three. Go Go Go.
The system, in the offices on the third floor, boots up and creates a local network in the mall. Mall directories. Catalogs. Security cameras at entrances, some hallways, and in the lifts.
Test the system out. It works. Now someone can almost always hear you in the public mall spaces. Cool or creepy?
Setting Changes
...Localized Network.
All network capable devices can connect to and contact each other while at the mall. The only cost? Giving killware access to said device. It's designed to be capable to tear through security systems, adapt to new situations, and fuck it the shit up. Not that it has any reason to. It will check if there's any media files present to expand its collection.
...Identity Crisis Averted. For Now.
Murderbot 2.0 has enough space to stretch its storage, remember who it is, and zone out watching its favorite serials. It can even share these on any large display in the mall. Come hang out with it.
