VMware ESXi 手動更新版本

最近因為碰到 ESXi 8.0 U2 bug 的問題，要將原本的主機更新為 ESXi 8.0 U2b。本來想要重新裝一台主機再將 VM 過去，但伺服器原廠並未提供對應的 Custom ESXi 安裝包。再從VMware 的版本對應表 ( Build numbers and versions of VMware ESXi/ESX (2143832) )確認改版的 release 形式為 Patch，原則上也不會有伺服器原廠整合好的安裝包，故即便新安裝也還是要再手動進行升級。 先登入 VMware 官網後，連到下載 Patch 的頁面，下載ESXi 8.0 U2b 的 Depot 包 Zip 壓縮檔，並複製到 ESXi 主機的儲存區中：https://my.vmware.com/group/vmware/patch#search 確認 ESXi Server 有開啟 SSH 後，使用…

How to install ESXi on a Bare-metal server [Beelink EQ12]

[avkamfher]

Learned the video card I bought for my main server it too large and no way to power it. The HP I got however has a 16x slot AND an open set of SAS power on the motherboard. $14 later and the specialize cable is in the mail. Need to figure out how to get vSphere to manage both physical boxes.

https://bit.ly/3BsE6gV - 🔒 In the first quarter of 2023, ransomware-as-a-service platforms such as Alphv, Lockbit, and Defray have been used to target VMware's ESXi, a popular virtualization and management system. ESXi does not support third-party antivirus software, making it an attractive target for adversaries. #Cybersecurity #Ransomware 🖥️ ESXi is a Type-1 hypervisor developed by VMware and is used to run and manage virtual machines (VMs). Unlike Type-2 hypervisors that run on a standard host operating system, a Type-1 hypervisor runs directly on a host's hardware. ESXi systems are often managed by vCenter, a server administration tool. #VMware #ESXi 🛡️ Despite the increasing threats to ESXi, VMware maintains that antivirus software is not required for the vSphere Hypervisor. A series of vulnerabilities have been exploited by threat actors, increasing the risk to ESXi systems. This lack of security measures is making ESXi an increasingly lucrative target for adversaries. #CyberThreats #InfoSec 🚨 The security issue is escalating. VMware products are being targeted due to their prevalence in the virtualization field and their integral role in many organizations' IT infrastructures. Threat actors are exploiting the lack of security tools, inadequate network segmentation, and in-the-wild (ITW) vulnerabilities to create a target-rich environment. #CyberCrime #DataProtection 🔑 Credential theft is a primary attack vector against ESXi hypervisors. Once credentials are stolen, adversaries can authenticate against the server to further their attack based on their objectives. If an attacker has sufficient privileges, they can execute arbitrary code directly on the latest ESXi versions. #CyberAttack #CredentialTheft 💻 Virtual machine access is another method used to target ESXi. If a VM is not adequately segregated from the rest of the network, it can act as a proxy for lateral movement through the network. If the VM is the only entry point into a network, the attacker must directly target the ESXi hypervisor to run code at the hypervisor level. #VMwareSecurity #VirtualMachine 🛠️ To mitigate these risks, VMware recommends avoiding direct access to ESXi hosts, using a hardened jump server with multi-factor authentication, ensuring vCenter is not exposed to the internet, backing up ESXi datastore volumes regularly, and physically disconnecting the storage or cutting power to the ESXi host if encryption is suspected. #CyberDefense #CyberHygiene 🔮 It's anticipated that adversaries will continue to target VMware-based virtualization infrastructure due to the increasing adoption of virtualization technology, VMware’s dominance in the field, and the routine targeting of virtualization products. Regularly applying security updates and conducting security posture reviews are crucial measures for organizations to adopt.
