Ransomware operators exploit ESXi hypervisor vulnerability for mass encryption

Microsoft Security researchers have observed a vulnerability used by various ransomware operators to get full administrative access to domain-joined ESXi hypervisors and encrypt the virtual machines running on them. The vulnerability involves creating a group called “ESX Admins” in Active Directory and adding an attacker-controlled user account to this group. This manipulation of the Active Directory group takes advantage of a privilege escalation vulnerability (CVE-2024-37085) in ESXi hypervisors that grants the added user full administrative access to the ESXi hypervisor. The vulnerability was fixed by VMware in their June release and ESXi administrators should install this security update.

But experts say Fin7 has roared back to life in 2024 — setting up thousands of websites mimicking a range of media and technology companies — with the help of Stark Industries Solutions, a sprawling hosting provider is a persistent source of cyberattacks against enemies of Russia.

Die finanziellen und betrieblichen Auswirkungen eines Ransomware-Angriffs sind schon schlimm genug. Wenn es den Cyberkriminellen allerdings zusätzlich gelingt, die Backups zu schädigen oder zu verschlüsseln, ist die Wahrscheinlichkeit hoch, dass ein Unternehmen rund das doppelte an Lösegeld zahlen muss. Laut einer Studie von Sophos bei 2.974 IT-/Cybersecurity-Entscheidern in 14 Ländern fallen die Gesamtkosten für die […]
