FBI Issues Warning About Increasing Ragnar Locker Ransomware Activity
Threat actors using Ragnar Locker ransomware have stepped up their attacks and have been targeting businesses and organizations in many sectors, according to a recent private industry alert from the Federal Bureau of Investigation (FBI). Ragnar Locker ransomware was first identified by security researchers in April 2019, with the first known attack targeting a large corporation that was issued with an $11 ransom demand for the keys to decrypt files and ensure the secure deletion of the 10 terabytes of sensitive data stolen in the attack. While not named in the FBI alert, the attack appears to have been on the multinational energy company, Energias de Portugal. The gang was also behind the ransomware attacks on the Italian drinks giant Campari and the Japanese gaming firm Capcom. Since that attack, the number of Ragnar Locker victims has been steadily growing. Attacks have been successfully conducted on cloud service providers, and companies in communication, construction, travel, enterprise software, and other industries. As with other human-operated ransomware attacks, the threat...
Free Google Services Abused in Phishing Campaigns
Several phishing campaigns have been identified that are using free Google services to bypass email security gateways and ensure malicious messages are delivered to inboxes. Phishing emails often include hyperlinks that direct users to websites hosting phishing forms that harvest credentials. Email security gateways use a variety of methods to detect these malicious hyperlinks, including blacklists of known malicious websites, scoring of domains, and visiting the links to analyze the content on the destination website. If the links are determined to be suspicious or malicious, the emails are quarantined or rejected. However, by using links to legitimate Google services, phishers are managing to bypass these security measures and ensure their messages are delivered. The use of Google services by phishers is nothing new; however, security researchers at Arborblox have identified an uptick in this activity that has coincided with increased adoption of remote working. The researchers identified 5 campaigns abusing free Google services such as Google Forms, Google Drive, Google Sites,...
HHS Releases Final Rules with Safe Harbors for Cybersecurity Donations
On Friday last week, the Department of Health and Human Services’ Centers for Medicare and Medicaid Services (CMS) and Office of Inspector General (OIG) published final rules that aim to improve the coordination of care and reduce regulatory barriers. Both final rules contain safe harbor provisions that allow hospitals and healthcare delivery systems to donate cybersecurity technology to physician practices. The CMS released the final version of the 627-page Modernizing and Clarifying the Physician Self-Referral Regulations, commonly called Stark Law, and the OIG finalized revisions to the 1,049-page Safe Harbors Under the Anti-Kickback Statute and Civil Monetary Penalty Rules Regarding Beneficiary Inducements. Physician practices often have limited resources, which makes it difficult for them to implement solutions to address cybersecurity risks. Without the necessary protections, sensitive healthcare data could be accessed by unauthorized individuals, stolen, deleted, or encrypted by threat actors. Threat actors could also conduct attacks on small physician practices and...
Phishing Incidents Reported by Connecticut Department of Social Services, Mercy Iowa City and LSU Care Services
Connecticut Department of Social Services (DSS) has reported a potential breach of the protected health information of 37,000 individuals as a result of a series of phishing attacks that occurred between July and December 2019. Several email accounts were compromised and were used to send spam emails to several DSS employees, the investigation of which confirmed the phishing attacks. A comprehensive investigation was conducted using state information technology resources and a third-party forensic IT firm, but no evidence was found to indicate the attackers had accessed patient information in the email accounts. According to the DSS breach notice, “Due to the large volume of emails involved and the nature of the phishing attack, the forensic efforts could not determine with certainty that the hackers did not access personal information.” Identity theft protection services have been offered to affected individuals as a precaution and steps have been taken to improve email security and better protect against phishing attacks in the future. More Than 92,000 Individuals Affected by...
Three More Healthcare Providers Suffer Cyberattacks Involving Ransom Demands
Three healthcare providers in New York, Florida, and Georgia have started notifying patients that some of their protected health information was potentially compromised in recent cyberattacks, two of which involved ransomware and one involved an unspecified computer virus. Four Winds Hospital, NY Four Winds Hospital in Katonah, NY, discovered files had been encrypted by ransomware on or around September 1, 2020. The attack prevented the hospital from accessing its computer systems and resulted in downtime of around two weeks while the attack was mitigated. Upon discovery of the attack, steps were immediately taken to prevent any further unauthorized system access and third-party cybersecurity experts were engaged to help identify the scope of the attack and whether patient data had been compromised. According to Four Winds Hospital’s substitute breach notice, “[The cybersecurity experts] obtained evidence that the cybercriminals deleted any files in their possession, although that evidence cannot be independently verified.” That suggest a ransom was paid, although that has not been...
