In February 2014, Tesco faced a significant security breach when customer account information was compromised due to a hacker attack. This event highlighted Tesco's history of poor online security and raised concerns about the protection of sensitive customer data.
How many accounts were compromised?
The breach impacted data related to approximately 2,000 individuals.
What data was leaked?
The data exposed in the breach included email addresses, passwords, and reward program balances of affected Tesco customers.
How was Tesco hacked?
In the 2014 Tesco breach, hackers compiled data from other web services, testing email and password combinations from high-profile hacks against Tesco's website. Over 2,000 customer usernames and passwords were posted online, leading to unauthorized access to personal details and Tesco Clubcard vouchers.
Tesco's solution
In response to the 2014 data breach, Tesco took several measures to secure its platform and prevent future incidents. The company deactivated the affected online customer accounts and contacted all potentially impacted customers, advising them to change their passwords to something unique and secure.
How do I know if I was affected?
Tesco notified customers believed to be affected by the breach. If you're a Tesco customer and haven't received a notification, you may visit HaveIBeenPwned, a platform that monitors data breaches and can notify individuals if their data has been disclosed in recognized data leaks.
What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the breached account. Make sure the new password is strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
Enable Two-Factor Authentication (2FA): Activate 2FA on the breached account and consider enabling this additional security feature on all other important online accounts to significantly reduce the risk of unauthorized access.
