Hackers gain access to data at major e-marketing company
Servers at Epsilon, the world's largest permission based email marketing service, have been breached, affecting customers of a wide range of major brands. While mostly only e-mail addresses have been harvested in this hack, it should not be dismissed as a minor threat. Possession of these addresses along with associated business names allows to target customers who expect communication from these companies, making phishing attacks more likely to be successful.
An incomplete list of businesses whose customers' e-mail addresses may have fallen into the wrong hands can be viewed here.
One of the affected businesses, US Bank, already informed its clients about this on Saturday, April 2nd.
