Ransomware Attack on The Cancer Center of Hawaii Delayed Radiation Therapy for Patients
On November 5, 2019 The Cancer Center of Hawaii in Oahu was attacked with ransomware. The attack forced the Cancer Center to shut down its network servers, which meant it was temporarily prevented from providing radiation therapy to patients at Pali Momi Medical Center and St. Francis’ hospital in Liliha. While patient services experienced some disruption, no patient information is believed to have been accessed by the attackers. The forensic investigation into the breach is ongoing but all data stored on its radiology machines has been recovered and its network is now fully operational. It is unclear for how long its network was down and no information has been released so far on the types of patient information that may have been accessed. The Cancer Center has notified the FBI about the breach and will report the incident to appropriate authorities, if the forensic investigators confirm that patient data may have been accessed. The breach was confined to the Cancer Center’s systems. Pali Momi Medical Center and St. Francis’ hospital were unaffected by the attack as their patient...
MSPs and Healthcare Organizations Targeted with New Zeppelin Ransomware Variant
A new ransomware variant is being used in targeted attacks on managed service providers, technology, and healthcare firms, according to security researchers at Blackberry Cylance. Attacks are being conducted on carefully selected, high profile targets using a new variant of VegaLocker/Buran ransomware named Zeppelin. VegaLocker has been around since early 2019 and all variants from this family have been used to attack companies in Russian speaking countries. The campaigns were broad and used malvertising to direct users to websites hosting the ransomware. The latest variant is being used in a distinctly different campaign that is much more targeted. Attacks have only been detected on companies in Europe, the United States, and Canada so far. If the ransomware is downloaded onto a device in the Russian Federation, Ukraine, Belorussia, or Kazakhstan, the ransomware exits and does not encrypt files. Ransomware variants from the VegaLocker family have all been offered as ransomware-as-a-service and there are indications that the same is true of Zeppelin ransomware, although the...
Amazon Lex is Now HIPAA Compliant
Amazon has announced that the Amazon Lex chatbot service now supports HIPAA compliance and can be used by healthcare organizations without violating Health Insurance Portability and Accountability Act Rules. Amazon Lex is a service that allows customers to build conversational interfaces into applications using text and voice. It allows the creation of chatbots that use lifelike, natural language to engage with customers, ask questions, collect and give out information, and complete a range of different tasks such as scheduling appointments. The conversational engine that powers Amazon Lex is also used by Amazon Alexa. Until recently, there was limited potential for use of Amazon Lex in healthcare as the solution was not HIPAA-compliant and could therefore not be used in connection with electronic protected health information (ePHI). The service was also not covered by Amazon’s business associate agreement (BAA). On December 11, 2019, Amazon confirmed that Amazon Lex is now included in its AWS business associate agreement (BAA) addendum and that the service is eligible for use with...
Patients Notified of Phishing Attack at Cheyenne Regional Medical Center
Cheyenne Regional Medical Center in Wyoming has recently learned that patient information may have been compromised as a result of a phishing attack discovered in April. The medical center was alerted to a potential security breach following the detection of suspicious activity related to employee payroll accounts on or around April 5, 2019. Around a week later, the medical center learned that employee email accounts had been compromised. The investigation revealed the attackers had gained access to employee email accounts between March 27, 2019 and April 8, 2019. The aim of the attack appears to have been to access employee payroll information, although patient information contained in email accounts may also have been accessed. The types of information potentially accessed varied from patient to patient and may have included names, dates of birth, Social Security numbers, driver’s license numbers, dates of service, provider names, medical record numbers, patient identification numbers, medical information, diagnoses, treatment information, and health insurance information. A very...
Ryuk Ransomware Decryptor Bug May Result in Permanent Data Loss
Cybersecurity firm Emsisoft has issued a warning about a recently discovered bug in the decryptor used by Ryuk ransomware victims to recover their data. A bug in the decryptor app can cause certain files to be corrupted, resulting in permanent data loss. Ryuk ransomware is one of the most active ransomware variants. It has been used in many attacks on healthcare organizations in the United States, including DCH Health System in Alabama and the recent attack on the IT service provider Virtual Care Provider. Ryuk ransomware is distributed in several ways. Scans are conducted to identify open Remote Desktop Protocol ports, brute force attacks on RDP are also conducted, and the ransomware is downloaded by exploiting unpatched vulnerabilities. Ryuk ransomware is also installed as a secondary payload by Trojans such as TrickBot. There is no free decryptor for Ryuk ransomware, so recovery depends of whether viable backups have been made, otherwise victims must pay a sizeable ransom for the keys to decrypt their files. When Ryuk ransomware victims pay the ransom, they are provided with a...
