The Information Commissioner’s Office, the independent supervisory authority for data protection in the UK, has fined 23andMe, a genetic testing service, £2.31 million following an investigation into a cyber attack that happened in 2023.
Between April and September 2023, an attacker carried out a credential stuffing attack, which exploited reused login credentials that were stolen from previous unrelated cyber attacks. Credential stuffing is when login details, usually stolen from another breach, are tried on different services, relying on users reusing the same passwords.
