What does it mean when the hash for an application shows as a long chain of zeroes/0s, or when this message is seen for an Event?
Origin: The file with hash 0000000000000000000000000000000000000000000000000000000000000000 was detected by Confer
An all zero hash indicates a System process or thread running within the kernel level of the Operating System (OS), and there is not an actual file to be hashed. This will typically show when a System process/thread is performing some work either on the endpoint or over the network.
Blacklisting or otherwise blocking such a hash will have a negative impact on normal Operating System functionality, and should not be done
A hash of all zeroes can also be called a synthetic hash
