Title: New U.S. federal warning highlights MedusaLocker group targeting health care organizations

Description: The FBI and U.S. Cybersecurity and Infrastructure Security Agency warned of an uptick in activity from the MedusaLocker ransomware group. The group, which has been around since 2019, gained notoriety during the COVID-19 pandemic for targeting health care organizations. The group operates as a ransomware-as-a-service model, according to the joint alert, based on the way it splits payments. Medusa recently switched to a new infiltration method by targeting vulnerable RDP configurations. Then, it can carry out a variety of actions, including killing popular anti-virus software processes, schedules a task to run the ransomware every 15 minutes and deletes local backups.

Title: Popular wireless data router vulnerable to code execution vulnerabilities

Description: Cisco Talos recently discovered four vulnerabilities in the Robustel R1510 industrial cellular router. The R1510 is a portable router that shares 2G, 3G and 4G wireless internet access. It comes with several advanced software features for users like the ability to connect to a VPN, cloud data management and smart reboot. There are three command injection vulnerabilities that exist in this device, as well as a data removal vulnerability that could allow an attacker to arbitrarily remove files from the device. An attacker could trigger the command injection issues — CVE-2022-32585, CVE-2022-33312 - CVE-2022-33314 and CVE-2022-33325 - CVE-2022-33329 — by sending a specific series of requests to the targeted device. If successful, the attacker could gain the ability to execute remote code.
