Healthcare Industry Most Commonly Attacked with Downloaders and Ransomware
Blackberry has recently published its Global Threat Intelligence Report, which provides actionable and contextualized intelligence that can be used to improve cyber resilience. The report is based on data collected by Blackberry and threat intelligence provided by third parties, gathered over 90 days between September and November 2022. Throughout the reporting period, downloaders were among the most commonly observed threats. Downloaders are malicious software that often masquerade as legitimate digital documents and executables and are used to download a range of other malicious software. Once installed, these downloaders often remain undetected for long periods and form large botnets of infected devices. The operators of these botnets partner with other threat groups to deliver third-party payloads. One of the most commonly used downloaders is Emotet, which first emerged in 2014 as a banking Trojan. An international law enforcement operation successfully shut down the Emotet botnet in April 2021 but it was eventually rebuilt and started to be used again at the end of 2021. After...
Feds Warn of Malicious Use of RMM Software in Callback Phishing Attacks
Cybercriminals are increasingly using legitimate remote monitoring and management (RMM) software in their attacks, according to a recent joint alert from the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Multi-State Information Sharing and Analysis Center (MS-ISAC). The campaign was first identified in October 2022 and involves callback phishing. The emails used in this campaign are difficult for email security solutions to identify as malicious as they contain no malicious hyperlinks or attachments. The emails notify the recipient about an impending charge and a phone number is provided in the email for the user to call if they want to avoid the charge being applied. The charges typically relate to a software solution that is coming to the end of a free trial. The user is told that the full price of the software will be charged to the user’s account if no action is taken. Due to the high cost of the software, there is a reasonably high chance that the number will be called. The call is answered and social engineering...
Ransomware Profits Decline as Victims Refuse to Pay Ransoms
Ransomware gangs are finding it much harder to profit from their attacks as fewer victims are ransoms to obtain the decryption keys and prevent the exposure of stolen data, according to two recently released reports from the ransomware remediation firm, Coveware, and blockchain analysis firm, Chainalysis. Coveware reports that in Q1, 2019, 85% of ransomware victims paid the ransom following an attack. Since then, the percentage making payments has been steadily declining, with just 37% of ransomware victims paying up in the last two quarters of 2022. Coveware said around 50% of organizations paid ransoms in 2021, compared to 41% in 2022. Chainalysis said total ransomware revenue fell by 40.3% year-over-year, dropping from $765.6 million in 2021 to $456.8 million in 2022. While ransomware victims do not always publicly disclose attacks or if a ransom has been paid, the figures strongly suggest there is an increasing unwillingness of victims to pay up. There are several reasons for the decline in profits. Organizations have improved their defenses, are monitoring their networks more...

Second Class Action Lawsuit Filed Against CommonSpirit Health Over Ransomware Attack
Another lawsuit has been filed against CommonSpirit Health over its 2022 ransomware attack and data breach that alleges the nation’s largest catholic health system failed to implement reasonable and appropriate HIPAA safeguards to prevent unauthorized access to sensitive patient data. CommonSpirit Health announced in early October that it was dealing with a cyberattack that took down its IT systems, then in December confirmed that the individuals behind the ransomware attack had access to certain parts of its network from September 16 through October 3, 2022, during which time they may have accessed or obtained the protected health information of 623,774 patients including names, contact information, birth dates, and internal patient identifiers. The latest lawsuit was filed on January 13, 2022, in the U.S. District Court for the Northern District of Illinois on behalf of plaintiff Jose Antonio Koch, his two minor children (John/James Doe), and other similarly affected individuals. Koch and his children received medical care at St. Michael Medical Center in Silverdale, WA, a...
