The company confirmed to Krebs that it discovered and fixed a vulnerability on its enterprise portal, but not before an attacker got through and stole basic contact information. Verizon didn't elaborate on how the hacker got in, but the spokesperson said that "no customer proprietary network information (CPNI) or other data was accessed or accessible."

If only basic contact info was stolen, those customers won't have to worry about identity theft or credit card fraud. However, the real worry here is that this could be a source for targeted attacks/phishing that turn into the next cryptolocker or leaked W-2 mess.
