Philadelphia-based real estate company Brandywine Realty Trust (NYSE: BDN) last week fell victim to a ransomware attack that disrupted some of its business applications.
In a filing with the US Securities and Exchange Commission (SEC) on Monday, the real estate investment trust revealed that the incident occurred on May 1 and involved unauthorized access to portions of its IT environment.
The attackers, the company says, deployed file-encrypting ransomware on a portion of its internal corporate systems, disrupting business applications that support certain operations and corporate functions, such as the financial and operating reporting systems.
“Upon detecting the unauthorized occurrences, the company promptly initiated its previously established response protocols and began taking steps to contain, assess and remediate the incident, including beginning an investigation with leading external cybersecurity experts, activating its incident response plan, shutting down some systems and notifying law enforcement,” the real estate company says.
Brandywine Realty Trust also notes that the incident has been contained and that it has started restoring the impacted IT systems. The company’s real estate operations have not been affected and the incident has not had a material impact on operations yet.
The company says it has evidence that the attackers have exfiltrated certain files from the compromised systems, but has yet to determine the extent of the data breach and whether any personal information was stolen.
“As the investigation of the incident is ongoing, the full scope, nature and impact of the incident are not yet known,” Brandywine Realty Trust says, adding that it does not believe the attack will materially impact its financial condition or results of operations.
One of the largest publicly traded real estate companies in the US, Brandywine Realty Trust invests in office buildings in Philadelphia, Austin, Texas, and Washington, D.C.
