Verizon Enterprise Services
After a report emerged from security journalist Krebs in March, Verizon Enterprise Services announced that it had been the victim of a data breach that affected more than a million of its enterprise customers. The breach allowed hackers to collect information on an estimated 1.5 million enterprise clients, including basic contact information. Verizon said no customer proprietary network information or other data was accessed. It is not clear what the exact cause of the breach was, but Verizon said it had recently found and fixed a vulnerability in its enterprise client portal used by the hacker to collect the information. Partners at the time said the breach highlighted concerns around telecom providers, who pose an attractive target to hackers as they hold an extensive amount of customer information.
