Some security applications (e.g. Rubrik) may detect a threat or vulnerability on vCenter Server appliances that hold a file like the following:
/var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/snapshots/<X>/fs/usr/bin/toybox
The scans flag this "toybox" tool as a potential threat.
vCenter Server appliances which contain these "toybox" files, return the following when running find . -name "toybox" from the /var/lib/ directory:
root@vcenter[ /var/lib ]# find . -name "toybox"
./containerd/io.containerd.snapshotter.v1.overfs/snapshots/2/fs/usr/bin/toybox
./containerd/io.containerd.snapshotter.v1.overfs/snapshots/23/fs/usr/bin/toybox
vCenter Server 7.x
The "toybox" file is a binary tool used by vCenter/vSphere to manage and reduce the size of container (Docker) images.
The scan can be safely ignored.
"toybox" files on vCenter Servers is expected and by design.
