Chicago Accountancy Firm Discovers Data was Stolen in December 2020 Ransomware Attack
The Chicago, IL-based accountancy firm Bansley and Kiener LLP has announced it was the victim of a December 2020 ransomware attack that saw certain files within its systems encrypted. The attack only caused temporary disruption, and it was possible to restore all encrypted systems from backups and rapidly return to normal operations. The attack occurred on December 10, 2020, and the subsequent investigation into the incident found no evidence of data theft and confirmed that the breach had been fully contained. However, Bansley and Kiener said in a December 3, 2021 data breach notification letter that the firm learned on May 24, 2021, that the attackers had exfiltrated some files from its systems, and those files contained sensitive client information. A third-party cybersecurity firm was engaged to assist with the subsequent investigation and while it was not possible to confirm the specific types of information that had been accessed and exfiltrated, on August 24, 2021, the investigation confirmed the names and Social Security numbers of some individuals may have been obtained by...
PHI of 750,000 Patients of Oregon Anesthesiology Recovered Following Ransomware Attack
On July 11, 2021, Oregon Anesthesiology Group discovered it was the victim of a ransomware attack. Files on its systems had been encrypted which prevented access to its servers and patient data. Following the attack, its IT infrastructure was reconstructed and offline data backups were used to promptly restore the affected files. A digital forensics firm was engaged to investigate the breach and it was confirmed that patient and employee information had been compromised, with the affected parts of its network found to contain files that included names, addresses, dates of service, diagnosis and procedure codes and descriptions, medical record numbers, insurance provider names, and insurance ID numbers. Employee data potentially compromised in the attack included names, addresses, Social Security numbers, and other information contained in W-2 forms. The forensic investigation revealed that once the hackers had gained access to its network, they data-mined administrator credentials which allowed them to access encrypted data on its network. The FBI told Oregon Anesthesiology Group...
Planned Parenthood Los Angeles Facing Class Action Lawsuit Over October 2021 Ransomware Attack
Planned Parenthood Los Angeles (PPLA) is facing a class action lawsuit over a ransomware attack that was discovered on October 17, 2021. The cyberattack exposed the protected health information of more than 409,759 patients. In the notification letters sent to affected individuals on November 30, 2021, PPLA explained that its systems were breached on October 9, 2021, and the hackers had access to files containing PHI until October 17, when they were ejected from the network. The files on the affected systems contained names, addresses, birth dates, diagnoses, treatment, and prescription information, and some files were exfiltrated from its network prior to file encryption. PPLA said it has found no evidence to suggest patient data has been misused. A PPLA patient whose PHI was exposed in the data breach has taken legal action over the incident. The lawsuit was filed in the U.S. District Court of Central California and alleges the patient, and class members, have been placed at imminent risk of harm as a result of the theft of their sensitive health data, which included electronic...
Learnings from a Major Healthcare Ransomware Attack
One of the most serious healthcare ransomware attacks occurred in Ireland earlier this year. The Health Service Executive (HSE), the Republic of Ireland’s national health system, suffered a major attack that resulted in Conti ransomware being deployed and forced its National Healthcare Network to be taken offline. That meant healthcare professionals across the country were prevented from accessing all HSE IT systems, including clinical care systems, patient records, laboratory systems, payroll, and other clinical and non-clinical systems which caused major disruption to healthcare services across the country. Following the attack, the HSE Board commissioned PricewaterhouseCoopers (PWC) to conduct an independent post-incident review into the attack to establish the facts related to technical and operational preparedness and the circumstances that allowed the attackers to gain access to its systems, exfiltrate sensitive data, encrypt files, and extort the HSE. Cybersecurity Failures that are Common in the Healthcare Industry PWC’s recently published report highlights a number of...
Max-Severity Apache Log4j Zero-day Vulnerability Extensively Exploited in the Wild
A maximum-severity vulnerability has been identified in Apache Log4j, an open-source Java-based logging library used by many thousands of organizations in their enterprise applications and by many cloud services. The vulnerability, dubbed Log4Shell and tracked as CVE-2021-44228, is serious as they come, with some security researchers claiming the flaw is the most serious to be discovered in the past decade due to its ease of exploitation and the sheer number of enterprise applications and cloud services that are affected. The vulnerability can be exploited without authentication to achieve remote code execution and take full control of vulnerable systems. The vulnerability affects Apache Log4j between versions 2.0 to 2.14.1, and has been fixed in version 2.15.0. The advice is to ensure the upgrade is performed immediately as a proof-of-concept exploit for the flaw is in the public domain, extensive scans are being performed for vulnerable systems, and there have been many cases of the flaw being exploited in the wild. Some reports suggest the improper input validation bug has been...
