The recent news of the Yahoo breach and leak of hundreds of millions of passwords, names, dates of birth, and other
personal information has led to headlines across the country. Understandably, given Yahoo’s popularity, people are worried. Especially as a summer dominated by news of leaks, hacks, and foreign intelligence agencies with nefarious agendas comes to an end.
Given that reports suggest that the initial breach of this data occurred in 2014, one of the primary concerns about this type of data dump are password reuse attacks, where cybercriminals take previously compromised credentials and use them to break into accounts on other platforms where the victim used the same username/password combination. It’s only a matter of time before criminals use the credentials leaked in the Yahoo breach to attempt to compromise other accounts, such as financial accounts or social media profiles.
