BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.

To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.

To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.

Banner Health suffers massive cyberattack

Banner Health suffers massive cyberattack

Banner Health is contacting 3.7 million individuals whose personal information may have been accessed in a cyberattack that started on systems that process credit card payments for food and beverage purchases at Banner locations.

The breach then expanded to include patient and health plan information.

The health system, with locations in Alaska, Arizona, California, Colorado, Nebraska, Nevada and Wyoming, first learned of the attack on July 7, a company statement said. Around June 23, the attack began to target data from credit cards, including the card holders' names, card numbers, expiration dates and verification codes.

By July 13, an investigation revealed that the attackers “may have gained unauthorized access to patient information, health plan member and beneficiary information, as well as information about physician and healthcare providers,” the statement said. “The patient and health plan information may have included names, birthdates, addresses, physicians' names, dates of service, claims information, and possibly health insurance information and social security numbers.”

Banner announced Wednesday that it is mailing letters to 3.7 million patients, health plan members and food services customers about the attack. The health system has also hired a computer forensics firm, contacted law enforcement officials and is taking steps to prevent further attacks.

A list of the outlets that were affected can be found here.
