L'ho cercata anche io e ho trovato questa interpretazione su reddit che sembra filare:
Cyprus National Bank host several of their servers in Virtual Realty's datacentre in NYC. It's possible that the Deus Group instructed the bank to do just this.
When Elliot and Darlene broke into the Virtual Realty datacentre, they used a system administrator's credentials to encode a smartcard that would allow them to log into the server. It's common in high-security environments to use smart-cards instead of passwords (for instance, the NHS in the UK use smart card authentication to access patient records), and Windows directly supports this. This entire hack would have been unfeasible without physical access to the card printer.
At some point in the day, Darlene changes the administrative password for the database user 'sa' (server administrator). It's revealed that the bank is using Microsoft SQL Server as a backend. It looks like this particular server might not be the central client database, but a secondary database used by the banking application software. This is because the phone numbers are stored as a one-way hashed string in the database, so given a row from the database it would be very difficult to find the original phone number. This would be very unusual in your live customer database, which probably can't be accessed physically at the Virtual Realty datacentre.
In a previous episode, Elliot asks Darlene to get access to the SS7 network. SS7 is the signalling network that is basically the backbone of mobile networks. Data sent over the network is not encrypted except between cell towers and phones, so any provider on the network can read any data sent over it. It's safe to assume Darlene didn't have time to do this, which is why we see Elliot panicking over the cell tower access and why he phishes an employee for their login. This gives Elliot immediate engineering-level access to the provider, and this particular cell tower, which allows him to view all the traffic that passes over it. This gives us a list of phone numbers and IMSI numbers in the local area, allowing him to get whiter0se's cell number and IMSI.
Darlene drops a collection of devices outside the building in NYC. This contained a Raspberry Pi, and either an ISMI catcher or a Software Defined Radio. This effectively creates a fake mobile base station. Because the signal of this station is (reportedly) stronger than the 'real' base station, devices start to connect immediately. What makes this hack particularly effective is that mobile devices will always connect to a base station with the strongest signal, as they are required to by the GSM and LTE specifications.
To identify the Deus Group members, Darlene runs a script that takes every phone number connected to the fake cell tower and checks to see if it exists in the "Accounts" database of Cyprus National Bank. This allows her to determine every account controlled by a member of the Deus Group, and then store the IMSI number needed to intercept calls and SMS. The IMSI number is essentially the identifier used by a SIM card to prove its identity. Without high level engineering access to a mobile firm, it's very difficult to recover an IMSI for a subscriber. As Elliot gained SS7 access after his phishing attack, the pair can now spoof their phones.
Darlene's code to initiate bank transfers is interesting. Essentially, it is a looping script that emulates a browser connecting to an online banking website. What's interesting is that every time the script runs, it uses the same browser cookie, which is essentially the security token used to identify the logged in user. I think it's implied that they have authenticated to the online banking system as a member of banking staff, which probably bypasses the internal security. This is probably Olivia's boss, as it's confirmed that the boss has permission to make transfers on those accounts.
As Darlene has full employee-level banking access, the account she used had the permissions to transfer these huge sums provided that the client provided a MFA token.
We only see one interaction of Darlene's code run on screen, and it transferred at least $140 billion from a single account. This looks like an internal transfer, as the account numbers shown are relatively simple (transfer from 1292829 to 1918893).
