Customers of Verizon Communications were victims of a large-scale data breach that exposed email addresses.
Someone hacked into online marketer Epsilons email system, exposing names and/or email addresses of customers of roughly 50 companies, including Verizon, Reuters reported.
Epsilon has assured us that the information exposed was limited to email addresses, and that no other information about you or your account was exposed,” Verizon said in an email to a customer.
Epsilon revealed last week that a subset of its clients customer data, specifically email addresses and/or customer names, was exposed as a result of unauthorized entry into its email system. Epsilons parent corporation, Alliance Data Systems Corp., today reaffirmed that the data breach was limited to email addresses and/or customer names and that no personally identifiable information, such as social security or credit card numbers, was compromised.
Dallas-based Alliance Data said it is working with federal authorities and outside forensics experts to investigate the matter.
The company urged all consumers to take appropriate precautions and be vigilant with regard to opening emails and/or accessing links sent by unknown sources.”
On its website, Epsilon states that it is the worlds largest permission-based email marketing provider, sending over 40 billion emails annually.”
