eHealth Email Spoofing Attack Sees Employee W-2 Information Disclosed
In the past few days, two email spoofing attacks have been reported by healthcare organizations that have resulted in the W-2 information of employees being sent to cybercriminals. Tax season phishing scams are to be expected at this time of year. Cybercriminals target HR and payroll employees and try to fool them into sending the W-2 information of employees via email. The scams are convincing. A casual glance at the address of the sender of the email will reveal nothing untoward. The emails appear to have been sent from other employees who have a legitimate need for the information. The latest healthcare organization to report being duped by one of these scams is eHealthinsurance. An eHealth employee responded to a phishing email on January 20, 2017 after believing it had been sent from another eHealth employee. While many of these scams involve emails being sent from compromised company email accounts, in this case the request came from a spoofed email account. The employee sent a file by return that contained employees’ W-2 tax forms. Data passed on to the scammer included...
OIG: 16% Increase in Security Gaps in Medicare Contractors’ Information Security Programs
An annual review of Medicare administrative contractors’ (MACs) information security programs has shown them to be ‘adequate in scope and sufficiency’, although a number of security gaps were found to exist. The Social Security Act requires each MAC to have its information security program evaluated on an annual basis by an independent assessor. Each MAC must have the eight major requirements of the Federal Information Security Management Act of 2002 (FISMA) evaluated, in addition to the information security controls of a subset of systems. The Department of Health and Human Services’ Office of Inspector General (OIG) is required to submit a report of the annual MAC evaluations to congress. The Centers for Medicare & Medicaid Services (CMS) contracted with PricewaterhouseCoopers (PwC) for this year’s evaluations. The OIG report to congress shows a total of 149 security gaps were discovered to exist in the financial year 2015; a marked increase from the previous year. In 2014, the same 9 MACs were evaluated and 16% fewer security gaps were discovered. A security gap is defined...
Tax Season Triggers Wave of W-2 Business Email Compromise Attacks
Campbell County Health is the latest victim of a W-2 business email compromise attack, which has resulted in the tax information of 1,457 hospital employees being disclosed to a scammer. The Gillette, WY-based healthcare system discovered Wednesday that an employee had responded to an email request for the W-2 form data of hospital employees. As is common in these scams, the attacker impersonated a hospital executive and requested W-2 information for all employees who had taxable earnings in 2016. A 66-year old hospital worker responded to the email and sent the information as requested. However, rather than being sent to the hospital executive, the data was sent to the scammer. Andy Fitzgerald, CEO of Campbell County Health issued a statement confirming “no protected health information for our employees or our patients were released in this incident.” The breach was limited to W-2 data. All affected employees have now been contacted and have been offered identity theft protection services through a leading credit monitoring and identity theft protection company. Law enforcement...
Healthcare Organizations Warned About Fileless Ransomware Attacks
Over the past two years, ransomware has grown to become one of the biggest cybersecurity threats. While most infections are random, the healthcare industry has been targeted in 2016 and the outlook for 2017 remains bleak. Many healthcare organizations attacked with ransomware have been able to make a full recovery by deleting systems and reconstituting data from backups. However, there have been numerous cases over the past 12 months when data restoration from backups has failed. In such cases, healthcare organizations are faced with two options: Accept data loss or pay the attackers for the keys to unlock the encryption. In February, Hollywood Presbyterian Medical Center chose the latter, and paid the attackers $17,000 for the keys to unlock the encryption. 2016 saw major new ransomware variants unleashed, with Locky and Samas (Samsam) two of the biggest threats. Both ransomware variants have been used to attack healthcare providers in 2016, with the former reportedly used to in the HPMC attack and the latter reportedly used in a major attack on Medstar Health in March, 2016.

Email Account Compromised: 1,200 MultiCare Patients Affected
The Tacoma, WA-based MultiCare Health System has announced that the email account of one of its employees has been compromised by a hacker following a successful phishing attack. The five-hospital health system issued a statement yesterday about the email security breach confirming patients’ protected health information had been compromised. It is unclear when access to the email account was first gained, although the email security breach was discovered by MultiCare Health on November 27, 2016. An investigation into the breach was immediately launched and rapid action was taken to secure the health system’s email accounts, including resetting passwords on all email accounts. However, the investigation revealed that only one email account had been compromised. An analysis of the email account revealed that emails contained the ePHI of 1,200 former and current patients. Data potentially accessed by the attacker included patients’ names, addresses, dates of birth, genders, dates of service, account balances, and diagnosis and treatment information. MultiCare has confirmed that the...
