A potential threat

Tenno,

We’ve received reports that a suspicious being has been spotted in Missions across the Solar System.

A mysterious figure has been lurking in the shadows, watching Tenno as they proceed through Missions. Security cameras have caught this figure trailing Tenno on Jupiter, Eris and Europa -- with reports of new locations being added by the hour.

It is unknown whether this figure is a threat. It has been exhibiting the strange behavior of re-stocking lockers, crates and storage containers with Health and Credits once Tenno have cleared the area. For the meantime, it is requested that you stay alert and report any strange behavior near storage containers.

Beware and proceed with caution, Tenno. The Stocker is among us.

*Update! We have just received a clear image of The Stocker:
