Malware mentions in Healthcare

This chart shows the trending malware related to Healthcare within a curated list of cyber sources over the past week.

Weekly Industry View

Industry Information
Healthcare
The United States Department of Health and Human Services issued a warning to healthcare organisations about ongoing attacks from the Royal ransomware gang. The actors are believed to be focused on targeting US healthcare organisations, having claimed to have leaked all allegedly stolen data following each compromise. The group uses social engineering to trick corporate victims into installing remote access software following callback phishing attacks impersonating software providers and delivery services.
Cryptocurrency
Trend Micro researchers observed a cryptocurrency mining attack that leverages the Chaos remote administration tool (RAT). The attack flow involves terminating competing malware and killing off resources that influence cryptocurrency mining performance on Linux devices. Chaos RAT achieves persistence by altering a UNIX task scheduler file that, in this instance, downloads itself every 10 minutes from Pastebin. Additional payloads are then downloaded, including an XMRig miner and its configuration file, a shell script looping ‘competition killer’ and Chaos RAT. Chaos RAT is a Golang compiled binary that can perform reverse shell, download, upload, and delete files, take screenshots, and more.
Government
A new email campaign by the North Korean hacking group Kimsuky is targeting individuals who are influential in foreign governments to better understand where Western policy is headed on North Korea. This includes imitating other research entities to ask researchers and other experts on North Korea about their opinions on policy, and to write and comment on reports. The attackers appear to be successful, as multiple experts have provided information to a Kimsuky attacker account. The campaign marks as shift in tactics since groups like Kimsuky are known to usually infect targets with malware to steal sensitive information.
Technology
Researchers from SentinelLabs, Mandiant, and Sophos observed prominent threat actors abusing legitimately signed Microsoft drivers in active intrusions. The malicious driver and its loader, tracked as POORTRY and STONESTOP respectively, are designed to terminate antivirus and endpoint detection and response processes. Several distinct malware families, associated with distinct threat actors, were identified to have signed using this process. This includes UNC3944, Cuba ransomware, and Hive ransomware.
Critical Infrastructure
Cyble researchers observed a recent spike in Mallox ransomware samples in the wild, indicating that the malware is active and spreading rapidly. Spam emails are used to deliver an unknown .NET loader, which downloads encrypted malicious content from a remote server, decrypts it in the loader memory, and executes it. The malicious content is executed in memory without the actual payload being saved to the disk to evade antivirus detection. The loader then downloads and decrypts the ransomware binary in memory, before executing it. The ransomware stops numerous services and programs upon execution, as well as GPS-related programs, suggesting the ransomware could be targeting organisations dealing with critical infrastructure.
