A shared value says the hosts were set up alike, not that one operator runs them.

Of these, 40 are listed under an earlier value and 13 are past the 40 hosts shown.

JA4X template · 420 other hosts · 417 listed

These hosts’ certificates share one JA4X template, which points to the same certificate tooling. It is not evidence of a single operator.

Of these, 40 are listed under an earlier value and 380 are past the 40 hosts shown.

Cobalt Strike watermark · 42 other hosts · 42 listed

The watermark identifies the Cobalt Strike licence a beacon was built with. Cracked and leaked builds share watermarks widely, so it is not evidence of a single operator.

Of these, 7 are listed under an earlier value and 35 are past the 40 hosts shown.
