FBI Warns U.S. Healthcare Sector of Targeted BlackCat Ransomware Attacks

FBI Warns U.S. Healthcare Sector of Targeted BlackCat Ransomware Attacks
Feb 28, 2024 Ransomware / Healthcare
The U.S. government is warning about the resurgence of BlackCat (aka ALPHV) ransomware attacks targeting the healthcare sector as recently as this month. "Since mid-December 2023, of the nearly 70 leaked victims, the healthcare sector has been the most commonly victimized," the government  said  in an updated advisory. "This is likely in response to the ALPHV/BlackCat administrator's post encouraging its affiliates to target hospitals after operational action against the group and its infrastructure in early December 2023." The alert comes courtesy of the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Health and Human Services (HHS). The BlackCat ransomware operation suffered a major blow late last year after a coordinated law enforcement operation led to the  seizure of its dark leak sites . But the takedown turned out to be a failure after the group managed to regain control of the

Cybersecurity for Healthcare—Diagnosing the Threat Landscape and Prescribing Solutions for Recovery

Cybersecurity for Healthcare—Diagnosing the Threat Landscape and Prescribing Solutions for Recovery
Feb 21, 2024 Endpoint Security / Healthcare
On Thanksgiving Day 2023, while many Americans were celebrating, hospitals across the U.S. were doing quite the opposite. Systems were failing. Ambulances were diverted. Care was impaired. Hospitals in three states were  hit by a ransomware attack , and in that moment, the real-world repercussions came to light—it wasn't just computer networks that were brought to a halt, but actual patient care itself.  Cybercriminals are more brazen than ever, targeting smaller healthcare organizations for big payouts. Sure, it would be nice to believe thieves once lived by a code of conduct, but if one ever existed, it's been torn to shreds and tossed into the wind. Sophisticated hacker groups are now more than happy to launch cyberattacks on medical clinics, nursing homes, and other health service providers. Small- to mid-sized healthcare organizations have, unfortunately, become vulnerable targets from which cybercriminals can easily steal sensitive data, extort heavy ransoms, and, worst of all,

U.S., U.K., Australia Sanction Russian REvil Hacker Behind Medibank Breach

U.S., U.K., Australia Sanction Russian REvil Hacker Behind Medibank Breach
Jan 24, 2024 Cryptocurrency / Cybercrime
Governments from Australia, the U.K., and the U.S. have imposed financial sanctions on a Russian national for his alleged role in the 2022 ransomware attack against health insurance provider Medibank. Alexander Ermakov (aka blade_runner, GistaveDore, GustaveDore, or JimJones), 33, has been tied to the breach of the Medibank network as well as the theft and release of Personally Identifiable Information (PII) belonging to the Australian company. The ransomware attack, which  took place in late October 2022  and attributed to the  now-defunct REvil ransomware crew , led to the unauthorized access of approximately 9.7 million of its current and former customers. The stolen information included names, dates of birth, Medicare numbers, and sensitive medical information, including records on mental health, sexual health and drug use. Some of these records were leaked on the dark web. As part of the trilateral action, the sanctions  make  it a criminal offense to provide assets to Erma

Iranian State-Sponsored OilRig Group Deploys 3 New Malware Downloaders

Iranian State-Sponsored OilRig Group Deploys 3 New Malware Downloaders
Dec 14, 2023 Malware / Cyber Espionage
The Iranian state-sponsored threat actor known as  OilRig  deployed three different downloader malware throughout 2022 to maintain persistent access to victim organizations located in Israel. The three new downloaders have been named ODAgent, OilCheck, and OilBooster by Slovak cybersecurity company ESET. The attacks also involved the use of an updated version of a known OilRig downloader dubbed  SampleCheck5000  (or SC5k). "These lightweight downloaders [...] are notable for using one of several legitimate cloud service APIs for [command-and-control] communication and data exfiltration: the Microsoft Graph OneDrive or Outlook APIs, and the Microsoft Office Exchange Web Services (EWS) API," security researchers Zuzana Hromcová and Adam Burgher  said  in a report shared with The Hacker News. By using well-known cloud service providers for command-and-control communication, the goal is to blend with authentic network traffic and cover up the group's attack infrastructure

Unveiling the Cyber Threats to Healthcare: Beyond the Myths

Unveiling the Cyber Threats to Healthcare: Beyond the Myths
Dec 12, 2023 Data Security / Healthcare,
Let's begin with a thought-provoking question: among a credit card number, a social security number, and an Electronic Health Record (EHR),  which commands the highest price on a dark web forum?   Surprisingly, it's the EHR, and the difference is stark: according to a  study , EHRs can sell for up to $1,000 each, compared to a mere $5 for a credit card number and $1 for a social security number. The reason is simple: while a credit card can be canceled, your personal data can't. This significant value disparity underscores why the healthcare industry remains a prime target for cybercriminals. The sector's rich repository of sensitive data presents a lucrative opportunity for profit-driven attackers. For 12 years running, healthcare has faced the highest average costs per breach compared to any other sector.  Exceeding an average of $10 million per breach , it surpasses even the financial sector, which incurs an average cost of around $6 million. The severity of this iss

How to Protect Patients and Their Privacy in Your SaaS Apps
Jul 24, 2023 SaaS Security / Healthcare
The healthcare industry is under a constant barrage of cyberattacks. It has traditionally been one of the most frequently targeted industries, and things haven't changed in 2023. The U.S. Government's Office for Civil Rights reported  145 data breaches  in the United States during the first quarter of this year. That follows 707 incidents a year ago, during which over 50 million records were stolen. Health records often include names, birth dates, social security numbers, and addresses. This treasure trove of data is used in identity theft, tax fraud, and other crimes. It is the high value of the data that makes healthcare applications such a promising target. The healthcare industry was hesitant to adopt SaaS applications. However, SaaS applications lead to better collaboration among medical professionals, leading to improved patient outcomes. That, combined with SaaS's ability to reduce costs and improve financial performance, has led to the industry fully embracing SaaS solutions

Cynet Protects Hospital From Lethal Infection

Cynet Protects Hospital From Lethal Infection
May 25, 2023 Incident Response
A hospital with 2,000 employees in the E.U. deployed Cynet protections across its environment. The hospital was in the process of upgrading several expensive imaging systems that were still supported by Windows XP and Windows 7 machines. Cynet protections were in place on most of the Windows XP and Windows 7 machines during the upgrade process, ensuring that legacy operating systems would not cause vulnerabilities or delay the activation of an  incident response plan . The hospital's I.T. security team appreciated this coverage after their previous provider abandoned support for Windows XP and Windows 7. "One of the many reasons we chose Cynet was their support of legacy Windows machines. It's expensive, difficult and time consuming to upgrade our imaging system software, but we needed protections as we slowly migrated to more current Windows environments. Cynet was one of the few providers that continue to protect these older Windows environments." The Attack Alo

CISA Warns of Critical Flaws in Illumina's DNA Sequencing Instruments
Apr 29, 2023 Healthcare / Cybersecurity
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released an Industrial Control Systems (ICS) medical advisory warning of a critical flaw impacting Illumina medical devices. The issues impact the Universal Copy Service (UCS) software in the Illumina MiSeqDx, NextSeq 550Dx, iScan, iSeq 100, MiniSeq, MiSeq, NextSeq 500, NextSeq 550, NextSeq 1000/2000, and NovaSeq 6000 DNA sequencing instruments. The most severe of the flaws, CVE-2023-1968 (CVSS score: 10.0), permits remote attackers to bind to exposed IP addresses, thereby making it possible to eavesdrop on network traffic and remotely transmit arbitrary commands. The second issue relates to a case of privilege misconfiguration (CVE-2023-1966, CVSS score: 7.4) that could enable a remote unauthenticated malicious actor to upload and execute code with elevated permissions. "Successful exploitation of these vulnerabilities could allow an attacker to take any action at the operating system level," CISA  sa

Why Healthcare Can't Afford to Ignore Digital Identity

Why Healthcare Can't Afford to Ignore Digital Identity
Mar 07, 2023 Digital Identity / Healthcare
Investing in digital identity can improve security, increase clinical productivity, and boost healthcare's bottom line.  —  b y Gus Malezis, CEO of Imprivata Digitalization has created immeasurable opportunities for businesses over the past two decades. But the growth of hybrid work and expansion of Internet of Things (IoT) has outpaced traditional 'castle and moat' cybersecurity, introducing unprecedented vulnerabilities, especially in the healthcare industry. Although all organizations have important data to secure, healthcare holds some of the public's most sensitive personal health information (PHI) – not to mention insurance and financial data, as well.  We all expect this information to be secured and protected, especially with HIPAA laws in place. However, due to increasing IT fragmentation and the growing sophistication of cyberattacks, this is no longer guaranteed. In fact, the number of individuals affected by health data breaches in the U.S. since 2009 is

Nov 07, 2022
Australian health insurer Medibank today confirmed that personal data belonging to around 9.7 million of its current and former customers were accessed following a ransomware incident. The  attack , according to the company, was detected in its IT network on October 12 in a manner that it said was "consistent with the precursors to a ransomware event," prompting it to isolate its systems, but not before the attackers exfiltrated the data. "This figure represents around 5.1 million Medibank customers, around 2.8 million ahm customers, and around 1.8 million international customers," the Melbourne-based firm  noted . Compromised details include names, dates of birth, addresses, phone numbers, and email addresses, as well as Medicare numbers (but not expiry dates) for ahm customers, and passport numbers (but not expiry dates) and visa details for international student customers. It further said the incident resulted in the theft of health claims data for about 16
