Dive Brief:

• Last week, hackers posted the contact information for around 1.5 million Verizon Enterprise Solutions customers, according to a report by KrebsOnSecurity. 
• A hacker in an online cybercrime thread offered to sell the entire data set for $100,000, but also gave potential buyers the option to purchase sets of 100,000 records for $10,000 each. 
• The hackers also offered to sell information about security weaknesses for Verizon's website. 

Dive Insight:

In the data breach, hackers targeted the branch of Verizon dedicated to helping its customers recover from data breaches. Though the company said no proprietary network information or other data was accessed, the breach has the potential to seriously damage Verizon Enterprise's reputation. 

Some recent reports have also said Verizon may be considering selling its enterprise business. In November reports surfaced that the company was exploring how to structure a sale as it continues to shift its focus to mobile services and connected devices.

Verizon Enterprise reportedly works with 99% of Fortune 500 companies, so many of those enterprises could find themselves the victims of targeted attacks or phishing scams, KrebsOnSecurity reports. 

“Verizon recently discovered and remediated a security vulnerability on our enterprise client portal,” said in a statement to KrebsOnSecurity. “Our investigation to date found an attacker obtained basic contact information on a number of our enterprise customers.”
