The Rockville, Md.-based landscape services firm Brightview, formerly called The Brickman Group, said an employee fell for a phishing scam and sent the personal information of about 700 workers to an unknown party.

The incident took place on Feb. 4, 2016, when a Brightview employee received and answered an email from an unknown source requesting “specific personal information of our team members” to include first, middle and last name, job title and division, employee ID, status, hourly rate, last date paid, annual salary, home address, date of birth, and Social Security number, said Eric Robinson, Brightview's chief human resources officer, in a letter to employees.

No banking information or credit card data was included in the data dump.

Robinson stated the company's computer system was not hacked and the event was caused strictly by human error.
