They would need less believable stories and to impersonate interns, subcontractors, etc. The pattern in the attacks could be extremely brazen, like impersonation of the editor themself or a higher position colleague to resist social checks. Pretty strange for a long term editor to have few paths to themselves within their own publisher. (Since each attempt to gain a new connection in the publisher risks someone noticing the email address is a fraud of their own company and cause revocations.) If the attack is 100 or 1000 times less effective it is probably written off as a complete waste of resources.
