American retailer Target Corp. has reportedly revealed that cyber criminals who launched the mega data breach, compromising data of about 110 million customers, used a vendor's credentials to exploit the system.
According to Fox News, a Target spokeswoman revealed that hackers used credentials they stole from one of its vendors, but declined to reveal what type of credentials were stolen.
The December credit card data breach on Target is touted as one of the biggest hack attacks in the history that left customers' details including names, phone numbers, and postal and e-mail addresses exposed, affecting up to one-third of the US population.
