Phishing Attacks Using Malicious URLs Rose 600 Percent in Q3, 2017
As recent healthcare breach notices have shown, phishing poses a major threat to the confidentiality of protected health information (PHI). The past few weeks have seen several healthcare organizations announce email accounts containing the PHI of thousands of patients have been accessed by unauthorized individuals as a result of healthcare employees responding to phishing emails. Report Shows Massive Rise in Phishing Attacks Using Malicious URLs This week has seen the publication of a new report that confirms there has been a major increase in malicious email volume over the past few months. Proofpoint’s Quarterly Threat Report, published on October 26, shows malicious email volume soared in quarter 3, 2017. Compared to the volume of malicious emails recorded in quarter 2, there was an 85% rise in malicious emails in Q3. While attachments have long been used to deliver malware downloaders and other malicious code, Q3 saw a massive rise in phishing attacks using malicious URLs. Clicking those links directs end users to websites where malware is downloaded or login credentials are...
Data Breach Highlights Danger of Using USB Drives to Store PHI
The Man-Grandstaff VA Medical Center in Spokane, WA has discovered two USB drives containing the protected health information of almost 2,000 veterans have been stolen. The two devices were being used to store data from a standalone, non-networked server that was being decommissioned. One of the devices was the master drive used to move the medical center’s Anesthesia Record Keeper database to its virtual archive server. According to a statement issued by the medical center, that transfer had taken place in January. It is unclear why the database was still on the drive. The devices were stolen on July 18, 2017 from a contract employee while on a service call to a VA hospital in Oklahoma City. Man-Grandstaff VA Medical Center was not able to determine exactly what information was stored on the USB drives, although the database on the virtual archive server was checked and found to contain full names, addresses, phone numbers, surgical information, insurance information, and Social Security numbers. 1,915 individuals who have potentially been affected are being notified of the breach...
Bad Rabbit Ransomware Spread Via Fake Flash Player Updates
A new ransomware threat has been detected – named Bad Rabbit ransomware – that has crippled businesses in Russia, Ukraine, and Europe. Some Bad Rabbit ransomware attacks have occurred in the United States. Healthcare organizations should take steps to block the threat. There are similarities between Bad Rabbit ransomware and NotPetya, which was used in global attacks in June. Some security researchers believe the new threat is a NotPetya variant, others have suggested it is more closely related to a ransomware variant called HDDCryptor. HDDCryptor was used in the ransomware attack on the San Francisco Muni in November 2016. Regardless of the source of the code, it spells bad news for any organization that has an endpoint infected. Bad Rabbit ransomware encrypts files using a combination of AES and RSA-2048, rendering files inaccessible. As with NotPetya, changes are made to the Master Boot Record (MBR) further hampering recovery. This new ransomware threat is also capable of spreading rapidly inside a network. The recent wave of attacks started in Russia and Ukraine on...
Nuance Communications Urged to Share Details of NotPetya Wiper Attack
While the healthcare industry was largely unaffected by the NotPetya wiper attacks in June, a HIPAA business associate of many U.S. healthcare organizations was badly affected. Burlington, MA-based Nuance Communications – a provider of dictation and transcription services – had the NotPetya wiper installed on its system. The attack crippled Nuance, preventing many healthcare organizations from using its services. It took a month for full services to be resumed. Many of the firm’s healthcare clients were prevented from using its services for several days, and in some cases weeks. While malware and ransomware attacks are usually reportable breaches under HIPAA Rules, Nuance Communications did not report its attack to the Department of Health and Human Services’ Office for Civil Rights. Nuance Communications conducted a risk assessment and determined that the nature of the attack did not warrant a report of the breach to be submitted to OCR. While NotPetya was initially thought to be ransomware, it was soon determined to be a wiper. The purpose of the attack was not data theft, but...
FirstHealth Attacked with New WannaCry Ransomware Variant
FirstHealth of the Carolinas, a Pinehurst, SC-based not for profit health network, has been attacked with a new WannaCry ransomware variant. WannaCry ransomware was used in global attacks in May this year. More than 230,000 computers were infected within 24 hours of the global attacks commencing. The ransomware variant had wormlike properties and was capable of spreading rapidly and affecting all vulnerable networked devices. The campaign was blocked when a kill switch was identified and activated, preventing file encryption. However, FirstHealth has identified the malware used in its attack and believes it is a new WarnnaCry ransomware variant. The FirstHealth ransomware attack occurred on October 17, 2017. The ransomware is believed to have been introduced via a non-clinical device, although investigations into the initial entry point are ongoing to determine exactly how the virus was introduced. FirstHealth reports that its information system team detected the attack immediately and implemented security protocols to prevent the spread of the malware to other networked devices....
