On Sept. 21, Flint, Michigan-based MRO supplies distributor Shively Brothers, Inc. announced notice of an incident involving potential unauthorized access to personal information of certain individuals.

Shively Brothers on Feb. 10 identified “irregular activity within its computer network,” according to a news release.

In response, the company said it immediately took steps to “secure its environment” and launched an investigation to determine the nature and scope of the incident. Shively Brothers determined that between Feb. 7and Feb. 10, an unauthorized actor gained access to certain Shively Brothers computer systems and potentially accessed and/or acquired certain files stored on accessed computer systems.

The company said it then undertook a “comprehensive review of the contents of the accessed files to identify whether they contained any sensitive information and to whom it relates.” Shively Brothers began notifying impacted individuals in April as it identified impacted individuals.

Near the end of June, the company said the detailed review was complete, and Shively Brothers began “taking steps to send the final notices to any additional individuals whose information was potentially accessed or acquired.”

“The type of information identified varies by individual,” the company said in a staement. “The investigation determined the following types of information was potentially accessed or acquired: name and one or more of Social Security number, driver’s license or government-issued identification number, financial account information and medical/health insurance information. Shively Brothers mailed letters to potentially affected individuals for whom it maintains an address.”

“Shively Brothers encourages potentially impacted individuals to remain vigilant against incidents of identity theft and fraud, to review account statements, and to monitor their credit reports for suspicious activity,” the company said.
