Hacking Incidents Reported by Chippewa County and Frideres Dental
The Chippewa County Human Resources Division in Wisconsin has recently discovered that the laptop computer of an employee has been compromised and 25-35MB of data was stolen from the device, including information protected under HIPAA. Access to the device was gained through a remote access application, which was downloaded to the device on February 28, 2023. An unknown individual then used the application to access the computer. The employee noticed the access on March 1, 2023, and alerted the IT department, which was able to block further access. According to Chippewa County officials, the unauthorized individual had access to the device for approximately 5 minutes, during which time files were exfiltrated. The investigation confirmed that the breach was limited to one device. It is unclear how the remote access application was downloaded to the device, but it is suspected that this was a drive-by download after the employee inadvertently clicked a link in a phishing email or on a website, or via a website pop-up. The files were reviewed, and it was confirmed that 7 of the copied...
KillNet Hacktivist Group Continues to Target U.S. Healthcare Organizations
The pro-Russian hacktivist group KillNet has continued with its attacks on healthcare organizations in the United States in retaliation for U.S. Congress’s support for Ukraine, and on January 28, 2023, the group launched its biggest wave of Distributed Denial of Service (DDoS) attacks to date – a coordinated attack on more than 90 healthcare organizations in 48 U.S. states. 55% of the targets were healthcare systems with at least one hospital and lone hospitals with Level I trauma centers. The increase in activity has prompted the Health Sector Cybersecurity Coordination Center (HC3) to issue a new Analyst Note about the group, which describes its latest activities, the tactics, techniques, and procedures observed in the recent attacks on the healthcare and public health (HPH) sector, and provides recommended mitigations to defend against and reduce the severity of the group’s attacks. The group has been active since at least January 2022 and has been actively targeting countries that have pledged support for Ukraine following the Russian invasion, especially NATO countries....
99% of Hospitals Use Website Tracking Code That Transmits Data to Third Parties
New research indicates virtually all U.S. hospitals have been using tracking software on their websites that captures visitor data, including health information, and transfers that information to third parties. The study – published this month in Health Affairs – was conducted by researchers at the University of Pennsylvania. They used the 2019 American Hospital Association (AHA) Annual Survey to identify hospitals and narrowed their study to nonfederal acute care hospitals with an emergency department, which were not ambulatory surgery centers or freestanding long-term care facilities – The websites of 3,747 U.S. hospitals were assessed in the study. The researchers used an open-source tool called WebXray to identify third-party tracking code and recorded data requests on the hospital websites over a 3-day period in 2021. The researchers also recorded cookies and data stored on browsers that would allow visitors to the websites to be tracked across the Internet. They found that 98.6% of the hospitals used at least one type of tracking code on their websites that...
Healthcare CISOs Undervalue Dark Web Intelligence
The dark web is extensively utilized by cybercriminals and is therefore a rich source of information… information that can be leveraged by organizations to improve their cyber defenses. The dark web is used by cybercriminals to buy and sell malware, leak sensitive data, and share vulnerabilities and techniques, techniques and procedures that can be used in cyberattacks, and utilizing that data can help organizations to gain an understanding of the threat actors that are targeting their organization, and how attacks are likely to occur. Dark web intelligence is used by organizations in many industries, but the healthcare industry lags behind other sectors in the use of dark web intelligence. According to a recent survey conducted for Searchlight Cyber, 80% of large enterprises across all industry sectors utilize dark web intelligence as part of their security strategy, with the finance sector leading in the adoption of dark web intelligence with 85% of financial organizations gathering data from the dark web. Yet only 57% of healthcare organizations use dark web intelligence to...
Tallahassee Memorial Healthcare: Patient Data Stolen in Cyberattack
Tallahassee Memorial Healthcare (TMH), a non-profit health system serving patients in North Florida and South Georgia, experienced a cyberattack in late January that forced it to operate under emergency downtime procedures for around two weeks. According to the TMH breach notification, unusual system activity was detected on February 3, 2023, and its systems were secured. A third-party cybersecurity firm was engaged to investigate the breach and determined that unauthorized individuals had access to its systems between January 26 and February 2, 2023, and exfiltrated files during that time. Cyberattacks such as this often involve ransomware, although it is unclear if ransomware was used in this attack. TMH did not share further information on the exact nature of the attack. The review of the stolen files has now been completed and affected individuals started to be notified about the incident on March 31, 2023.
