To unlock this achievement, you need a minimum of 3 daemons uploaded. The first cyberdeck you receive through story progression is the Militech Paraline. It has two base ram, four buffer size and two slots. The main concern for this achievement is the buffer size. Four really doesn't cut it. Visit a ripperdoc and look for a cyberdeck with a higher buffer size. I found the Biotech MK.3 with 10 base base ram, 7 buffer size and 5 slots for 25k eddies.
Now for the daemons, go to the character tab and select INTELLIGENCE then the BREACH PROTOCOL tab. Put a point in MASS VULNERABILITY AND BIG SLEEP. You will have one daemon unlocked by default with the cyberdeck. This puts us at three daemons.
Now it's time to get the achievement. Use BREACH PROTOCOL on enemies or cameras. Make sure there are several enemies along with cameras and other breachable stuff nearby. There should be three rows underneath SEQUENCES. If there are less, then move on till you get three. Once you have three, go to https://cyberpunk-hacker.com/
and input the information being requested. 1. Buffer size 2. Enter Code Matrix 3. Enter Sequences. It will solve the best path for you.
Here are screen grabs of the solver and what the solved problem looks like. I couldn't figure out how to insert screen grabs unless they were Xbox screenshots.https://imgur.com/gallery/UGsz1gE
