Microsoft Issues Advice on Defending Against Spear Phishing Attacks
Cybercriminals conduct phishing attacks by sending millions of messages randomly in the hope of getting a few responses, but more targeted attacks can be far more profitable. There has been an increase in these targeted attacks, which are often referred to as spear phishing. Spear phishing attacks have doubled in the past year according to figures from Microsoft. Between September 2018 and September 2019, spear phishing attacks increased from 0.31% of email volume to 0.62%. The volume may seem low, but these campaigns are laser-focused on specific employees and they are often very affective. The emails are difficult even for security conscious employees to recognize and many executives, and even IT and cybersecurity staff, fall for these campaigns. The emails are tailored to a specific individual or small group of individuals in a company, they are often addressed to that individual by name, appear to come from a trusted individual, and often lack the signs of a phishing emails present in more general phishing campaigns. These attacks are more profitable as some credentials are...
Southeastern Minnesota Oral & Maxillofacial Surgery Ransomware Attack Impacts 80,000 Patients
Southeastern Minnesota Oral & Maxillofacial Surgery (SEMOMS) has announced it has been attacked with ransomware and that the protected health information of up to 80,000 patients was potentially compromised in the attack. The attack was detected on September 23, 2019. The IT team responded and isolated the affected server and took steps to restore the encrypted data. It is unclear whether the ransom was paid or if the IT team was able to restore the server from backups. Assisted by computer forensics experts, SEMOMS determined that the affected server contained names and X-ray images and that the server had been accessed by an unauthorized individual. No evidence was uncovered to suggest any patient information was accessed or exfiltrated by the attackers, but the possibility of unauthorized ePHI access and data theft could not be discounted. Consequently, notification letters have been sent to all individuals whose protected health information was potentially compromised.

HIPAA Compliance Can Help Covered Entities Prevent, Mitigate, and Recover from Ransomware Attacks
Ransomware attacks are often conducted indiscriminately, with the file-encrypting software commonly distributed in mass spam email campaigns. However, since 2017, ransomware attacks have become far more targeted. It is now common for cybercriminals to select targets to attack where there is a higher than average probability of a ransom being paid. Healthcare providers are a prime target for cybercriminals. They have large quantities of sensitive data, low tolerance for system downtime, and high data availability requirements. They also have the resources to pay ransom demands and many are covered by cybersecurity insurance policies. Insurance companies often choose to pay the ransom as it is usually far lower than the cost of downtime while systems are rebuilt, and data is restored from backups. With attacks increasing in frequency and severity, healthcare organizations need to ensure that their networks are well defended and they have policies and procedures in place to ensure a quick response in the event of an attack. Ransomware attacks are increasing in sophistication and new...
Kalispell Regional Healthcare Sued Over 130,000-Record Data Breach
Kalispell Regional Healthcare in Montana is being sued over a phishing attack in which hackers gained access to employee email accounts containing the protected health information of almost 130,000 patients. The compromised email accounts contained patient information such as names, contact information, medical bill account numbers, medical histories, and health insurance information. Approximately 250 individuals also had their Social Security number exposed. The phishing attack occurred in May 2019, but it was not initially clear which, if any, patients had been affected. It took until August for forensic investigators to determine that patient information had potentially been compromised. All affected patients were notified, and the health system offered 12 months of free credit monitoring and identity theft protection services to patients whose Social Security numbers had potentially been compromised. One of the patients whose personal and health information was compromised, William Henderson, has now taken legal action over the data breach. The lawsuit was filed in Cascade...
Nebraska Medicine Discovers Insider Data Breach
Nebraska Medicine has discovered an employee has accessed the medical records of patients without any legitimate work reason for doing so over a period of almost three months. The privacy violation was discovered during a routine audit of its medical record system. The audit revealed the employee had first accessed patient records on July 11, 2019 and continued to do so until October 1, 2019 when the privacy violations were discovered. Upon discovery, steps were taken to prevent further unauthorized access while the matter was investigated. The employee in question was fired the day after the privacy violations were discovered. According to a statement released by Nebraska Medicine, affected individuals have been notified by mail and any individual whose Social Security number was potentially viewed has been offered complimentary credit monitoring services for 12 months as a precaution. Nebraska Medicine does not have any reason to believe that any sensitive information has been or will be misused, suggesting the employee was accessing the records out of curiosity. It is unclear...
