    •And: &h2=1&h3= is hardcoded, as is: BHI06233

    This is most likely a victim ID Marker which is common in this type of malware so that they can remember who they popped. They will also use victim names as 3rd level subdomains for their C2 callbacks.

    Based on public reporting this trojan was specifically built to target and compromise Baker Hughes International.

    The only recognizable name is from Microsoft called Orsam, so if you got detection on your network with this your f****d by APT.

      Yes, I think BHI06233 is probably a way to identify the victim (i.e. an individual or company), or a grouping of victims.
