Anything blacklisted by Livegrid = Suspicious Object. That's the name they use for it, like UDS for Kaspersky's Cloud.
Looking at the behavior on VT, it seems that this sample is something that will be detected by a lot of AVs when the sample is run but I'm not sure of course, since it also seems to load a vulnerable driver. The relation tab shows two vulnerable drivers, one of which is detected by ESET only. The other one is also an old one but not detected by well-known AVs at this time.
