Medical Associates of the Lehigh Valley in Pennsylvania (MATLV) has announced that it recently fell victim to a sophisticated ransomware attack on its network. The attack was detected on July 3, 2022, and immediate action was taken to contain the attack and prevent further unauthorized access to its network. Third-party forensics specialists were engaged to assist with the investigation and determine the nature and scope of the attack.

MATLV said the investigation did not uncover any evidence indicating the misuse of patient information, but parts of the network that were accessed by the attackers contained files that included the protected health information of 75,628 individuals, which may have been viewed or exfiltrated in the attack. The files contained names, addresses, email addresses, birth dates, Social Security numbers, driver’s license numbers, state ID numbers, health insurance provider names, medical diagnoses, treatment information, medications, and lab results. The types of information exposed in the attack varied from patient to patient.

Cybersecurity specialists evaluated the security measures that had been implemented prior to the attack and security has been reinforced based on their recommendations. Affected individuals have been encouraged to monitor their financial accounts and explanation of benefits statements and report any suspicious activity.

TennCare Reports Accidental Exposure of Patients’ PHI

TennCare, Tennessee’s state Medicaid program, has recently notified approximately 1,700 patients about the accidental exposure of some of their protected health information. According to a statement issued by TennCare officials, a new application was implemented that inadvertently associated people in one household with people in another household, if those households included some of the same people.

The issue was rapidly identified and corrected, but for a short period, the names and ages of affected people and their dependents would have been visible to other people who at one time were part of the same case file. For 15 individuals, more sensitive information was visible such as Social Security number, address, and date of birth. While the risk of misuse of information is believed to be low, affected individuals have been offered a 12-month complimentary membership to an identity theft protection and credit monitoring service, which includes a $1 million identity theft insurance policy.

Over the Labor Day weekend, Oakbend Medical Center in Richmond, TX, suffered a ransomware attack. The attack started on Thursday, September 1, 2022, and saw files on its network encrypted. The medical center said its IT team took all systems offline to contain the attack, and the medical center operated under lockdown procedures while the attack was investigated by the Federal Bureau of Investigation (FBI), the Cyber-Defense Campus CYD), and the Fort Bend County Government Cyberteam.

The internal IT team ensured that all patient-centric systems were secured, and cybersecurity experts from Microsoft, Dell, and Malware Protects were engaged to investigate the attack and assess the security of its systems. Once those systems were cleaned, work commenced on rebuilding those systems and restoring them in a controlled and systematic manner. Disruption is continuing to be experienced, and there have been temporary communication issues for patients, vendors, doctors, and administrators; however, at no point was patient safety at risk and the medical center continued to operate.

In a September 9, 2022, update, Oakbend Medical Center said the recovery process is ongoing and there are still issues with the telephone and email systems, but it is working to resolve those issues as quickly as possible. While Oakbend Medical Center did not confirm whether files containing patient data were exfiltrated from its systems, the ransomware gang responsible for the attack – Daixin Team – claimed on its data leak site that files were stolen prior to file encryption that contained patient information such as names, dates of birth, medical record numbers, patient account numbers, Social Security numbers, and medical and treatment information. Some of the stolen data has been uploaded to the group’s data leak site. The group has threatened to release all of the stolen files, which are claimed to include the protected health information of more than 1 million patients. At the time of publication, it would appear that the ransom has not been paid and all communication between the medical center and Daixin Team has stopped.

Daixin Team is a relatively new threat group that is known to attack hospitals. In June 2022, the group conducted an attack on Fitzgibbon Hospital in Missouri and stole and published files containing sensitive patient data.

This post will be updated when further information about the attack is released and when the total number of affected patients is known.

Birmingham, AL-based Henderson & Walton Women’s Center (HWWC) has recently notified 34,306 patients that some of their protected health information may have been compromised as a result of a hacker gaining access to the email account of one of its employees. HWWC said the forensic investigation of the data breach confirmed the attacker did not gain access to the email server and the breach was confined to the email account of one employee.

HWWC did not disclose when the email account was compromised but said there was a delay in issuing notification letters due to the lengthy process of reviewing all emails in the account to determine the types of information and specific individuals that had been affected. That process concluded on June 24, 2022.

HWWC said it had implemented encryption for all external emails, but the forensic investigation determined that stored emails may have been accessed. Those emails contained patient information such as names, dates of birth, Social Security numbers, medical information, health insurance information, driver’s license numbers, and state ID numbers. The information exposed varied from patient to patient.

Notification letters were sent to all affected individuals in August. As a precaution against identity theft and fraud, complimentary memberships have been offered to a credit monitoring service for 12 months. Steps have also been taken to improve the security of its email system, including implementing a new procedure for automatically deleting emails containing PHI after 3 days, and a system is being implemented that will prevent the sharing of any personal information via email.

Genesis Health Care Reports Cyberattack and Data Breach

Kennett Square, PA-based Genesis Health Care has recently notified the Montana Attorney General about a cyberattack that was detected on April 11, 2022. Suspicious activity was detected in certain IT systems, prompting a comprehensive investigation. Third-party digital forensics specialists were engaged to determine the nature and scope of the incident and help restore the functionality of its systems. The investigation confirmed on June 9, 2022, that files may have been accessed or exfiltrated from its systems between January 19, 2022, and April 11, 2022. A programmatic and manual review of the affected files confirmed on July 13, 2022, that they contained patient information including, but not limited to, names and Social Security numbers. Genesis Health Care said it is reviewing its policies and procedures and will evaluate additional measures and safeguards to prevent similar breaches in the future.

The breach has yet to appear on the HHS’ Office for Civil Rights breach portal, so it is currently unclear how many individuals have been affected.

The Michigan law firm, Warner Norcross and Judd LLP, has issued notification letters to 255,160 individuals advising them about an October 2021 security breach in which files containing their personal and protected health information were potentially accessed and exfiltrated from its systems. The breach was detected on October 22, 2021. The substitute breach notification does not state when, and for how long, unauthorized individuals had access to its systems.

A digital forensics firm was engaged to investigate the nature and scope of the data breach and a programmatic and manual review was conducted on files on the affected parts of its network. The review confirmed that the files contained information such as names, dates of birth, Social Security numbers, driver’s license numbers, government-issued IDs, annual compensation amounts, benefit contribution information, credit card or debit card numbers, credit card or debit card PINs, financial account or routing numbers, passport numbers, patient account numbers, health information, and life insurance policy information.

Notification letters were sent to affected individuals in August and information was provided on the steps that individuals can take to reduce the risk of identity theft and fraud, but it would appear that credit monitoring and identity theft protection services are not being offered. The law firm said it will be taking steps to improve security to prevent further data breaches.

Salida, CO-based First Street Family Health has suffered a destructive cyberattack, in which files containing patient information were exfiltrated and then deleted from its systems. This method of attack is becoming more common, where data is stolen, deleted, and then threats are issued to publish or sell the data if payment is not made to the attackers, but files are not encrypted using ransomware.

First Street Family Health said the attack was detected on July 16, 2022, with the investigation confirming that the attackers first gained access to its systems on July 5, 2022. The unauthorized access was blocked on July 16. The attackers deleted electronic medical records from June 28, 2021, to July 15, 2022, and while backups of those records had been made, the backups were also deleted so the information in those records has been lost. No evidence was found to indicate those records were stolen. Medical referral forms stored on the affected computer systems may have been viewed or acquired, but those records were successfully restored from backups.

The breached records included full names, addresses, birth dates, phone numbers, email addresses, Social Security numbers, dates of service, nature of services, diagnoses, conditions, lab results, medications, health insurance identification cards and numbers, and billing information.

Notification letters were sent to affected individuals on August 26, 2022, and complimentary memberships to CyberScout’s credit monitoring service have been offered. First Street Family Health said a national cybersecurity firm assisted with the investigation and conducted a security review, and additional security measures are being implemented based on the firm’s recommendations.

The incident has not yet appeared on the HHS’ Office for Civil Rights breach portal, so it is currently unclear how many individuals have been affected.
