However, it is this very habit that puts users at risk when online accounts get compromised. Since most users need to maintain online accounts, password security has long been a much ignored issue as most users do not want the burden of having to create and remember multiple passwords. This incident should serve as a reminder for all users to pay attention to their online security habits, especially when it comes to their online credentials. In addition, it has voided unencrypted security questions and answers to invalidate any attempts to use the stolen credentials. However, the company was quick to notify potentially affected users and has required victims to change their passwords. Unsurprisingly, Yahoo is coming under a lot of scrutiny as the hack happened so long ago and had gone unnoticed even after the investigation of the 2014 hack. Unfortunately, the passwords included that were leaked were secured with an encryption algorithm that could be easily cracked. They also stressed that financial data is not stored in the system that was compromised. Yahoo has yet to determine how the data of 1 billion users were stolen, but added that it appears no payment information such as credit card numbers and bank account details, or even unencrypted passwords were included in the hack. This attack involves user names, email addresses, telephone numbers, hashed passwords using the MD5 algorithm, and encrypted and unencrypted security question and answers found to have been stolen in 2013. ![]() According to Chief Information Security Officer, Bob Lord, it appears that the incident is likely distinct from the breach disclosed three months ago. This larger figure pales in comparison to a previous incident that announced last September, where 500 million accounts were stolen back in 2014. Yahoo disclosed Wednesday, December 14, that it had suffered yet another breach in August 2013 that exposed over 1 billion accounts.
