Healthcare Industry Targeted with Gatak Trojan
The healthcare industry is coming under attack by the actors behind the Gatak Trojan. Gatak, or Stegoloader as it is otherwise known, is not a new malware. The Trojan was first identified in 2011 and has since been used to attack a wide range of targets. However, according to a recent report by Symantec, the actors behind the malware have now set their sights firmly on the healthcare industry. 40% of the most affected organizations are now in the healthcare sector. This signifies a change in targeting, as previously the Trojan has been primarily used to attack insurance companies. While 40% of attacks have not been attributed to any industry sector, the next most targeted industries – which each account for 5% of attacks – are the automotive, education, gambling, and construction. It is currently unclear how the attackers are using the malware to profit from infections, although it is believed that healthcare companies are being targeted due to the value of their stored data. Gatak is primarily an information stealer There are two components of the malware. One component performs...
Vascular Surgical Associates Hacking Incident Reported
Vascular Surgical Associates – A group of specialty-trained vascular surgeons in Atlanta – has announced that it has been the victim of a hacking incident that has potentially resulted in certain protected health information being viewed by unauthorized individuals. IT staff noticed unusual activity on one of the company’s servers on or around September 13, 2016. An investigation into the anomaly was launched, which revealed the server had been improperly accessed using login credentials supplied to some of the group’s vendors. Access to patient data was first gained on March 25, 2016 when a software application upgrade was performed. The investigation did not confirm whether patient health information had been obtained by the hackers, although for more than five months it would have been possible for the login credentials to have been used to view patient data. As soon as IT staff determined the server had been compromised access was immediately terminated. The server is now secure and Vascular Surgical Associates is confident that no further unauthorized access is possible....
Privacy Breach Reported by Wentworth-Douglass Hospital
Wentworth-Douglass Hospital in Dover, New Hampshire has started alerting patients to a privacy breach experienced by one of its vendors, Ambucor Health Solutions. Ambucor Health Solutions provides a remote-monitoring service for cardiac devices for hospitals throughout the United States. Earlier this month, the company started notifying its clients of a privacy breach caused by one of its former employees. Prior to leaving employment, the employee downloaded sensitive company data onto two flash drives. The data breach was discovered by Ambucor Health Solutions over the summer and an investigation was launched. The incident was reported to law enforcement, and the subsequent investigation resulted in the flash drives being recovered in July. An analysis of the contents of the drives, which was completed in September, revealed the downloaded data included a range of electronic health information of cardiac patients from a number of the company’s clients, and included the protected health information of 775 patients of Wentworth-Douglass Hospital. Social Security numbers, financial...
New Attack Vector Used to Spread Locky Ransomware
This year, hospitals throughout the United States have been targeted by cybercriminals using ransomware. The malicious file-encrypting software is used to lock files that are critical for healthcare operations in the hope that a ransom payment will be made in order to regain access to locked data. In February, Hollywood Presbyterian was attacked and its computer systems were taken out of action for more than a week while the infection was removed. A ransom demand of $17,000 was issued and was paid by the Medical Center after attempts to recover files from backups failed. The attack is understood to have involved Locky ransomware. Locky encrypts a wide range of file types including office documents, pdf files, databases, and images. Files are renamed and new extensions are added to make it harder for victims to identify which files have been encrypted. Windows Shadow Copies are also deleted. Locky can spread laterally through a network and is capable of encrypting files on portable storage devices, such as those used for backing up data. The actors behind Locky distribute the...
UMass to Pay OCR $650K to Resolve HIPAA Violations
The Department of Health and Human Services’ Office for Civil Rights (OCR) has agreed to a $650,000 settlement with University of Massachusetts Amherst (UMass). The settlement resolves HIPAA violations that contributed to the university experiencing a malware infection in 2013. In early 2013, malware was installed on a workstation in the Center for Language, Speech, and Hearing. The infection resulted in the impermissible disclosure of the electronic protected health information of 1,670 individuals. Those individuals had their names, addresses, social security numbers, birth dates, health insurance information, diagnoses, and procedure codes disclosed to the actors behind the malware attack. Following the discovery of the infection in 2013, UMass conducted a detailed analysis of the infected workstation. The malware was a generic remote access Trojan and infection occurred because the workstation was not protected by a firewall. UMass ascertained that access to ePHI had been gained. OCR investigates all data breaches that impact more than 500 individuals to determine whether...
