Hospital officials said they were recently informed of the safety incident at cyberspace hit Blackbaud Inc., which works with many healthcare institutions and systems, hospitals and academic institutions across the country.
"Stamford Hospital uses Blackbaud software to assist in the management of communications and fundraising activities by donors or potential donors," the statement said.
Stamford is one of many hospitals in the area reported to be affected by data breach in Blackbaud. The Greenwich Hospital said some of its information may have been leaked as a result of the breach, including Nuvance Health, which includes Danbury, New Milford, Norwalk and Sharon.
On July 16, Stamford Hospital received a warning of an attack ransomware suffered by Blackbaud between 7 February and 20 May. During the violation, the criminals in cyberspace received a copy of some of Blackbaud's fundraising data for the hospital.
Blackbaud finally paid the ransom and the data was recovered. However, it is not entirely certain that they have not been leaked to an illegal forum.
Stamford Hospital conducted a review of the data affected by infringement and found that most of the information was related to demographics and charity.
It also found that some sensitive patient information may have been compromised, such as doctors' names or treatment departments. However, credit card information or bank accounts or social security numbers were not affected.
"Given the facts, Stamford Hospital does not believe that there are any steps that members of our donor community need to take to protect their information regarding this incident. However, Stamford Hospital is evaluating appropriate remedial measures to mitigate the risk of similar events in the future. "
These measures could include a reassessment of the hospital agreement with Blackbaud, the removal of sensitive data from the database of the company and the retraining of employees regarding the collection of information, the statement said.
