Data Successfully Encrypted in 75% of Healthcare Ransomware Attacks
A new report from Sophos on healthcare cybersecurity trends indicates data encryption occurred in 75% of ransomware attacks on healthcare organizations. Only 24% of surveyed healthcare organizations were able to detect an attack in progress and disrupt it before files were encrypted. Sophos says this is the highest rate of encryption and the lowest rate of disruption the company has seen in the past 3 years. Last year, healthcare organizations disrupted 34% of attacks before files were encrypted. “To me, the percentage of organizations that successfully stop an attack before encryption is a strong indicator of security maturity. For the healthcare sector, however, this number is quite low—only 24%. What’s more, this number is declining, which suggests the sector is actively losing ground against cyberattackers and is increasingly unable to detect and stop an attack in progress,” said Chester Wisniewski, director, field CTO, Sophos. Many ransomware gangs use double-extortion tactics, where files are encrypted after data exfiltration and a ransom must be paid to decrypt files and...
FBI Shares Intel on Emerging Initial Access Techniques Used by Ransomware Gangs
The Cyber Division of the Federal Bureau of Investigation (FBI) has issued a private industry notification that includes details of emerging techniques that are being used by ransomware gangs to gain initial access to victims’ networks. The FBI has identified several ransomware trends that are emerging or continuing and have been used in multiple attacks since July 2023 to gain initial access to networks. Several attacks have involved the exploitation of vulnerabilities in vendor-controlled remote access to casino servers, and companies have been victimized through legitimate system management tools to elevate network permissions. The Silent Ransom Group (aka Lunar Moth) has been conducting phishing attacks using messages containing a phone number that must be called to prevent a pending charge to an account. This type of attack is known as callback phishing and has been popular with ransomware gangs since 2022. Since the emails contain no malicious content other than a phone number, the emails are not blocked by email security solutions and often reach their intended targets. To...
New York AG Settles Data Breach Investigation of U.S. Radiology Specialists for $450,000
New York Attorney General, Letitia James, has announced a $450,000 settlement with U.S. Radiology Specialists Inc. to resolve allegations it failed to protect patients’ personal and health information. U.S. Radiology Specialists is one of the largest private radiology groups in the country and acts as a service provider for healthcare facilities throughout the United States. It also partners with other radiology groups, including the Windsong Radiology Group, which operates 6 facilities in Western New York. Windsong, like other partner companies, relies on U.S. Radiology Specialists for numerous services, including network management and protection. The Office of the Attorney General of the State of New York opened an investigation of U.S. Radiology Specialists into a large data breach that was reported in 2021 to determine whether it was caused by a failure to comply with the Health Insurance Portability and Accountability Act (HIPAA) and state laws. U.S. Radiology Specialists protected the networks of its partners with a SonicWall firewall. On January 22, 2021, SonicWall alerted...
HHS-OIG Issues General Compliance Program Guidance
The Department of Health and Human Services (HHS) Office of Inspector General (OIG) has published new “General Compliance Program Guidance.” In April 2023, HHS-OIG announced that it would be improving and updating its existing voluntary compliance program guidance documents, which were developed and published between 1998 and 2008. Rather than publish them in the Federal Register as it has in the past, the new guides will be added to the HHS-OIG website, the first of which is a 91-page guidance document that provides general compliance guidance, tools, and references. The General Compliance Program Guidance explains relevant Federal laws, the key Federal authorities engaged in healthcare business, and discusses general compliance risks, compliance programs, compliance program infrastructure, compliance program adaptations for small and large entities, and other compliance considerations. The document also includes information on healthcare fraud enforcement by HHS-OIG and other standards. The guidance is voluntary and nonbinding and does not create any new laws or legal...
November 8, 2023, Healthcare Data Breach Round-Up
Mulkay Cardiology Consultants at Holy Name Medical Center has recently confirmed that it fell victim to a ransomware attack. The attack was detected on September 5, 2023, when files on its network were encrypted. According to the breach notice, Mulkay was able to rebuild its systems and recover the encrypted files from backups. Third-party forensics experts were engaged to investigate the breach and determined that its systems were compromised between September 1, 2023, and September 5, 2023, and during that time, files were exfiltrated that contained personal and protected health information. The compromised information included names, addresses, dates of birth, Social Security numbers, driver’s license numbers or state IDs, medical treatment information, and health insurance information. Mulkay said it has enhanced its technical safeguards to prevent similar incidents in the future. Affected individuals have been notified and offered complimentary credit monitoring services. The breach was reported to the Maine Attorney General and HHS’ Office for Civil Rights as involving...
