Some observations about Russian #APT29, after dealing with them for years (my views, not my employer's):
#APT29 has used generic phishing emails, like "efax notification". They work on gullible users and hinder identification as targeted attack.

In my experience, once an attacker is tipped off to a response, a few things can happen. What happens likely depends on where they are in their mission, mission priority, tolerance for being publicly identified, etc. It also likely depends on how badly they think they're burned.
A victim identifying a phishing doc or phishing backdoor doesn't necessarily mean the op is blown. In fact, it may give the victim a false confidence if they found the initial infection but didn't follow lateral movement. Same if an attacker loses a couple of implants out of many
However, trying to remove large numbers of implants and missing some, CURLing all of their C2 from your network, uploading several post-exploit backdoor samples to VT, discussing the intrusion in email, etc. - those are things that are more likely to elicit a response.
