An explosion of cyberattacks is infecting servers around the world with crippling ransomware by exploiting a vulnerability that was patched two years ago, it was widely reported on Monday.

The hacks exploit a flaw in ESXi, a hypervisor VMware sells to cloud hosts and other large-scale enterprises to consolidate their hardware resources. ESXi is what’s known as a bare-metal, or Type 1, hypervisor, meaning it’s essentially its own operating system that runs directly on server hardware. By contrast, servers running the more familiar Type 2 class of hypervisors, such as Oracle’s VirtualBox, run as apps on top of a host operating system. The Type 2 hypervisors then run virtual machines that host their own guest OSes, such as Windows, Linux, or, less commonly, macOS.

Germany has chosen European Central Bank Director General of Information Systems Claudia Plattner as the new head of its cybersecurity agency, the first female appointed to the role.

Royal Ransomware is the latest ransomware operation to add support for encrypting Linux devices to its most recent malware variants, specifically targeting VMware ESXi virtual machines.

BleepingComputer has been reporting on similar Linux ransomware encryptors released by multiple other gangs, including Black Basta, LockBit, BlackMatter, AvosLocker, REvil, HelloKitty, RansomEXX, and Hive.

The new Linux Royal Ransomware variant was discovered by Will Thomas of the Equinix Threat Analysis Center (ETAC), and is executed using the command line.

Searching Google for downloads of popular software has always come with risks, but over the past few months, it has been downright dangerous, according to researchers and a pseudorandom collection of queries.

“Threat researchers are used to seeing a moderate flow of malvertising via Google Ads,” volunteers at Spamhaus wrote on Thursday. “However, over the past few days, researchers have witnessed a massive spike affecting numerous famous brands, with multiple malware being utilized. This is not ‘the norm.’”.
