The company said it found that the intruders had compromised accounts as far back as December 1, close to two weeks before its systems detected a “large volume” of failed logins to customer accounts on December 12. It’s why two-factor authentication, which Norton LifeLock offers, is recommended, as it blocks attackers from accessing someone’s account with just their password. In a notice to customers, Gen Digital, the parent company of Norton LifeLock, said that the likely culprit was a credential stuffing attack - where previously exposed or breached credentials are used to break into accounts on different sites and services that share the same passwords - rather than a compromise of its systems.

Thousands of Norton LifeLock customers had their accounts compromised in recent weeks, potentially allowing criminal hackers access to customer password managers, the company revealed in a recent data breach notice.
