From a very reliable source...
***The Reg uncovered that the person responsible worked offshore***
-The "subtle" error in updating batch scheduling software was made by an experienced, UK-based person.
-But with no-one in the UK left with a proper overview of the entire system, when the shit hit the fan India was instantly and completely overwhelmed, and had no idea where to start or who to contact.
-RBS Group pulled everyone in and stopped all other project work. People called out of retirement, past contractors etc were all contacted and many are still working 24 hour shifts. Triage was needed, with NatWest prioritised (most customers)
-But here is the scary bit.
Only three of the 4 main banks had had the update applied (NatWest, Ulster North and Ulster South). Had RBS itself also had the software, then the situation would in all likelihood have not been recoverable. Think about that.
This will. I am assured, rumble on for months and the opportunities for fraud are gigantic.
