Spectre meanwhile 'breaks the isolation between different applications' – 'it allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets.The individual California State Colleges were brought together as a system by the Donahoe Higher Education Act of 1960. This allows a program to access the memory, and also the secrets, of other programs and the operating system.'

Meltdown, Google explains, 'breaks the most fundamental isolation between user applications and the operating system.

Meltdown primarily affects Intel processors, while Spectre affects Intel, AMD and ARM processors. Read next: IBM 'had not seen evidence' of rigorous testing ahead of TSB migration disasterĪt the start of 2018, Google researchers revealed CPU hardware vulnerabilities called Meltdown and Spectre had affected almost all computers on the market. The Financial Times reports that the Spanish banking group is now considering selling TSB. TSB claimed that the problem was resolved later that day, but the debacle will further rupture the bank's relationship with parent company Sabadell. In July, TSB was still working its way through the backlog of complaints, when another outage struck, locking customers out of their online accounts once again. Immediately after the new system was switched on, many customers experienced problems logging in, while others were shown details from other people's accounts or inaccurate credits and debits on their own. Customers remained locked out of their accounts two weeks after the initial outage.

The problems arose from TSB's move to a new banking platform following its split from Lloyds Banking Group. Millions of TSB customers were locked out of their accounts after an IT upgrade led to an online banking outage.Ī planned system upgrade was expected to shut internet and mobile banking services down for one weekend in April 2018, but ended up causing months of disruption.
