Since Mr. Hands is extremely secretive and protected for the most part (partly by CDPR writers) from direct analysis of his personal information, I think now the open data about him that can be found in Cyberpunk is mostly exhausted. Anything we could find in direct access, we plus minus have already found. So it is now likely that if we want to learn anything about this colorful character, we will now have to move from “indirect” methods of data collection to “completely indirect”, or “indirect-indirect” methods. This borders on intellectual insanity, of course, but what to do?
This brings into focus two interesting characters that are related to Hands (if not by the lore of the game, then at least logically).
One of these characters is Sandra Dorsett. The other character is so in the shadows, and so closed and peculiar, that I don't even know if I should talk about him here - perhaps he deserves a separate topic.
So, Sandra:
This girl, like many in Night City, lives a double or even triple life.
On the first level, she is an arrogant, yet vulnerable and frightened corporate girl, whom V and Jackie rescue from the Scavengers' lair at the very beginning of the game.
Next, she appears as a talented netrunner, infiltrating closed areas of Cyberspace in an attempt to ferret out the secrets of the Night Corporation.
And on the third level, she is a cunning, clever and cruel agent of the New United States Intelligence Agency, the curator of a huge network of netrunners operating clandestinely in Night City.
She, or her accomplices attack a Netwatch patrol outside of Night City, and take out a Watch agent with the call sign “Gacut”. The Watch agents' computer reveals both the extent of Sandra's espionage activities and a long list of agents affiliated with her and working under her command in Night City.
This network is (possibly!) worth searching for additional data on Hands. Well, there's a reason why the CDPR lists all those agents with approximate locations where they could be found, right? Otherwise it would just be a great prank.
Hands, I believe, is much more secretive and experienced than Sandra - working in the secret departments of corporations has taught him a lot. It's hard to expect him to make the mistake of leaving open data about sepba. However, Sandra is younger, less experienced (as apparently are most of her employees), more impulsive, and easy to make mistakes. I don't rule out the possibility that Hands' data could be extracted from her intelligence network.
As can be seen from the above data, this particular assignment of Sandra is more concerned with the activities of Netwatch, while Mr. Hands tries not to get involved in confrontation with this organization, and even on the contrary, attracts mercenaries (V) to help the Watch in its work. In any case, however, Sandra's netrunner group data can be extremely useful.
(I only ask that you understand me correctly - I've gone through Cyberpunk 6 or 7 times with different endings, and I won't be the person to go through the game again, aiming specifically at finding these netrunners and their data. Well if someday there will be an ardent Cyberpunk fan endowed with a strong will and enthusiasm, this forum post might help him in his quest, who knows ))).
