Verizon EnterpriseVerizon Enterprise Solutions, which is the business branch of the wireless telecommunications giant, has been called upon more than once in recent years to help fortune 500 companies respond to data breaches, but now it’s facing a breach of its own. According to cybersecurity analyst Brian Krebs, a prominent member of an underground cybercrime forum recently put the data of approximately 1.5 million Verizon Enterprise customers up for sale. It’s important for people to know that no Verizon Wireless customer data was exposed. This breach is limited to the customers of Verizon Enterprise, though that is still certainly worth concern — especially considering approximately 97% of Fortune 500 companies use the company for their IT services.

What information is available about this breach?

So far, while Verizon has acknowledged the existence of a vulnerability and says it is notifying customers, little information is known about exactly how the breach happened. The company did assure that no Customer Proprietary Network Info (CPNI) — which is the specific information about the types of services customers use and how they use them — or similar data was accessed. It’s worrisome, nevertheless, to see a company which is often at the forefront of the response in the event of a data breach be successfully infiltrated itself. In addition to selling the whole lot of customer data for $100,000 (or in chunks of 100,000 records for $10,000), the cybercriminal responsible is also selling information about weaknesses in Verizon’s website.

What can Verizon Enterprise customers do?

Unfortunately, since there isn’t much concrete information yet as to the exact nature of the breach, customers who are concerned about their business and employees are left waiting to be contacted. You can try to contact Verizon Enterprise for more information and check the website for any updates that might be posted at a later date. In general, breaches take a little time to be investigated before an official announcement is made or restitution is offered.

Has there been a breach like this before?

This isn’t the first time a wireless provider has been in the news for a data breach — last April, a breach involving AT&T customer service call centers exposed the names and social security numbers of thousands of customers, and a breach of credit bureau Experian reported in October was responsible for exposing the personal information of 15 million T-Mobile customers and applicants. As always, these data breaches are a reminder that virtually no Internet-connected service is untouchable for cybercriminals, so consumers need to be careful with their information and regularly keep tabs on what’s going on in the security sphere.
