Hackers have found a new method to establish persistence on VMware ESXi hypervisors to control vCenter servers and virtual machines for Windows and Linux while avoiding detection.A modified level of trust is not enough for the ESXi system to accept it by default but the attacker also used the '-force' flag to install the malicious VIBs.
VMware is warning that ESXi VMs running on Linux kernel 5.19 can have up to a 70% performance drop when Retbleed mitigations are enabled compared to the Linux kernel 5.18 release. More specifically, the VMware performance team noticed regressions on ESXi virtual machines of up to 70% in computing, 30% in networking, and 13% in storage.
A new ransomware family called 'GwisinLocker' targets South Korean healthcare, industrial, and pharmaceutical companies with Windows and Linux encryptors, including support for encrypting VMware ESXi servers and virtual machines. On Wednesday, Korean cybersecurity experts at Ahnlab published a report on the Windows encryptor, and yesterday, security researchers at ReversingLabs published their technical analysis of the Linux version.
Kaspersky security researchers have disclosed details of a brand-new ransomware family written in Rust, making it the third strain after BlackCat and Hive to use the programming language. Luna, as it's called, is "Fairly simple" and can run on Windows, Linux, and ESXi systems, with the malware banking on a combination of Curve25519 and AES for encryption.
A new ransomware family dubbed Luna can be used to encrypt devices running several operating systems, including Windows, Linux, and ESXi systems.Discovered by Kaspersky security researchers via a dark web ransomware forum ad spotted by the company's Darknet Threat Intelligence active monitoring system, Luna ransomware appears to be specifically tailored to be used only by Russian-speaking threat actors.
A new ransomware operation called RedAlert, or N13V, encrypts both Windows and Linux VMWare ESXi servers in attacks on corporate networks. The Linux encryptor is created to target VMware ESXi servers, with command-line options that allow the threat actors to shut down any running virtual machines before encrypting files.
Black Basta is the latest ransomware gang to add support for encrypting VMware ESXi virtual machines running on enterprise Linux servers. In a new report, Uptycs Threat Research analysts revealed that they spotted new Black Basta ransomware binaries specifically targeting VMWare ESXi servers.
Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months. ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.
A new ransomware named 'Cheers' has appeared in the cybercrime space and has started its operations by targeting vulnerable VMware ESXi servers. We have seen many ransomware groups targeting the VMware ESXi platform in the past, with the most recent additions being LockBit and Hive.
The Hive ransomware operation has converted their VMware ESXi Linux encryptor to the Rust programming language and added new features to make it harder for security researchers to snoop on victim's ransom negotiations. Ransomware gang's Linux encryptors typically target the VMware ESXI virtualization platforms as they are the most commonly used in the enterprise.
