Healthcare Organizations Warned of Risk of Man-In-The-Middle Attacks
In its April cybersecurity newsletter, the Department of Health and Human Services’ Office for Civil Rights advised covered entities and their business associates to use the Secure Hypertext Transport Protocol (HTTPS) to ensure protected health information is not left unsecured. While HTTPS has been adopted by many covered entities to protect communications from man-in-the-middle attacks, OCR has relayed a recent warning from the United States Computer Emergency Readiness Team (US-CERT) about vulnerabilities that may be introduced by the use of products that inspect HTTPS traffic. The use of HTTPS inspection products increases security as it allows healthcare providers to detect malware and unsafe connections. Unsafe connections could potentially result in communications being intercepted, data being accessed or manipulated, or malicious code being run. However, OCR warns that certain HTTPS inspection products fail to correctly verify web servers’ certificates or do not pass on error messages and warnings to clients. In order for HTTPS inspection to occur, network traffic must be...
Small Business Cybersecurity Bill Heads to Senate
New legislation to help small businesses protect their data and digital assets has been approved by the Senate Commerce, Science and Transportation Committee this week. The new bill, which was introduced by Sen. Brian Schatz (D-Hawaii) last week, will now head to the U.S Senate. The legislation – the MAIN STREET (Making Information Available Now to Strengthen Trust and Resilience and Enhance Enterprise Technology) Cybersecurity Act will require the National Institute of Standards and Technology (NIST) to develop new guidance specifically for small businesses to help them protect themselves against cyberattacks. New NIST guidance should include basic cybersecurity measures that can be adopted to improve resilience against cyberattacks and mitigate basic security risks. Guidance and security frameworks have been developed by NIST to help larger organizations protect their assets and data, although for smaller businesses with limited knowledge of cybersecurity and a lack of trained staff and resources they can be difficult to adopt. What is needed is specific guidance for small...
Congress Advised to Offer Incentives to Improve Healthcare Threat Intelligence Sharing
With the healthcare industry under a sustained attack and the cyber threat landscape constantly evolving, law enforcement, the government, and private industry need to collaborate to counter the threat of cyberattacks. Cybercrime cannot be effectively tackled by organizations acting in isolation. The sharing of threat information is essential in the fight against cybercrime. Dissemination of this information makes it easier for law enforcement and government agencies to combat cybercrime. Accessing that information also allows healthcare entities to to take timely action to address vulnerabilities before they are exploited. Government and law enforcement agencies are educating healthcare organizations on the importance of sharing threat intelligence, although currently too few entities are sharing threat information. At a Congressional Energy and Commerce Committee hearing this week, cybersecurity experts made suggestions on how congress can improve threat information sharing and improve healthcare cybersecurity. At the hearing, Denise Anderson, president of the National Health...
Large Hospitals and Teaching-Focused Hospitals Face Greater Risk of Data Breaches
A study recently published in JAMA Internal Medicine examined recent healthcare data breach trends to determine which types of hospitals are the most susceptible to data breaches. The researchers analyzed breach reports submitted to the Department of Health and Human Services’ Office for Civil Rights between October 21, 2009 and December 31, 2016. During that time, 216 hospitals reported 257 breaches of more than 500 patient records. 33 hospitals experienced more than one data breach during that time frame. Four hospitals – Brigham and Women’s Hospital, Cook County Health & Hospitals System, Mount Sinai Medical Center and St. Vincent Hospital and Healthcare Inc – experienced three data breaches. Two hospitals – Montefiore Medical Center and University of Rochester Medical Center & Affiliates – experienced four data breaches. The researchers determined the size of the acute care hospitals by linking the facilities to their Medicare cost reports submitted to the Centers for Medicare and Medicaid Services in the 2014 fiscal year. 141 acute care hospitals were linked to CMS...
More than 55,000 Patients Impacted by ABCD Pediatrics Ransomware Attack
San Antonio, TX-based ABCD Pediatrics has discovered cybercriminals gained access to its servers and used ransomware to encrypt data, including the protected health information of its patients. The individuals behind the attack may also have gained access to data stored on the healthcare provider’s servers prior to ransomware being deployed. The breach report submitted to the Department of Health and Human Services’ Office for Civil Rights indicates 55,447 patients have been impacted. The attack involved a variant of CrySiS ransomware called Dharma, which started encrypting data on February 6, 2017. Dharma ransomware is not known to exfiltrate data; however, an analysis of the attack revealed a number of suspicious user accounts on the servers, suggesting access had been gained prior to the ransomware being installed. User logs were also discovered that indicated programs or users may have been on the servers for a limited period of time prior to the ransomware being installed. Fortunately, the encryption process was hampered by the anti-virus solution used by ABCD Pediatrics. ABCD...
