Data signatures
General
Finding the sites
Winter Nexus data-hacking signatures spawn in systems affected by volatile ice storms in HS, LS and NS.
LS sites are assumed to be the most valuable ones, followed by NS and then HS.
Exactly 30 minutes after a site despawns (shortly after hacking), a new signature respawns in the same system.
Unlocking the 2nd canister
In all sites, there's a 2nd canister that only can be hacked if a specific item (from Yoiul LADs) has been deposited into Sansha's Stormfield Projector.
In HS sites a Cryostatic Estimator is required to unlock the 2nd canister
In LS sites a Cryostatic Nullifier is required to unlock the 2nd canister
In NS sites a Cryostatic Suppressor is required to unlock the 2nd canister
