The new process builds stock and Vagrant virtual machines automatically in the same Linux-based infrastructure, while addressing Vagrant base-box requirements and compatibility with Hyper-V exports on Windows. ### Source excerpt Vagrant files, *.box, are pre-configured Virtual Machines (VM) VM images, which when imported into HashiCorp's Vagrant, allow for VMs to be interacted with via the command line. You create, start, interact, stop, destroy VMs all without leaving the terminal. Think containers (Docker/Podman), but for VMs. Previously we have been using HashiCorp's Packer to generate our HashiCorp's Vagrant images. Packer is a wrapper, around whatever hypervisor you wish, and it will automate installing the OS (unattended setup via preseeding), run any commands or scripts, export the VM and finally compress it. The down-side to Packer is that you need to have the chosen hypervisor installed on the host OS, you can't cross-build. If you use Linux, you can't build Window's Hyper-V. For a few years now , we have been using DebOS, to automate building our VMs. This has been working great for us. Recently we realized: "Why do we have two different systems, for the same purpose?". A little bit of digging into "how to make a vagrant base box VM" boils down to just a few requirements: Fix username (vagrant) Fix/Known pubic SSH keys (default/standard insecure keypairs) Able to perform superuser actions (sudo) Simple really, just need to make sure that Vagrant can easy access the VM! Optional items (and recommended), as it helps benefits user's rather than Vagrant: Known/Fix credentials (vagrant everywhere) SSH tweaks (speed up for airgap networks) All of this can be handled in a post-install step, which we have put into our Kali-VM build-script. Now, we are building all of our VMs, automatically, in the same matter (Stock and Vagrant), all in the same infrastructure setup (Linux!). Since Microsoft Windows 10 1607 / Server 2016, when exporting VMs, there would be 3 additional "binary" files, *.vmcx/*.vmrs included as well as an *.xml. As we were no longer exporting the VM from Hyper-V, but generating it outside of, we do not have these files. Now, we could create a "template" binary which would ## Akira Ransomware Indicators | Huntress DevFeed: [Akira Ransomware Indicators | Huntress]() Original publisher: [Read original article]() Author: Harlan Carvey Published: 2024-09-20T00:00:00Z Content type: article Language: en Sources: [Huntress Blog]() Topics: [ransomware](), [Security](), [Malware](), [account](), [Encryption](), [Cybercrime](), [Server](), [Network](), [Windows](), [incident]() Tags: [akira](), [analysts](), [attacks](), [deployment](), [encryption](), [huntress](), [malware](), [microsoft-windows](), [network](), [passwords](), [ransomware](), [security](), [server](), [software](), [user]() ### AI overview Huntress analysts describe indicators linked to Akira ransomware attacks, including new or compromised accounts, lateral movement, exposed MSSQL servers, RDP access, hidden Windows accounts, and incomplete security-agent coverage. Earlier detection of these indicators may help organizations prevent ransomware deployment and file encryption. ### Source excerpt Tracking various indicators associated with different attacks, Huntress analysts have been able to identify specific indicators (threat actor workstation names, passwords associated with new user account creation or current account modification, CloudFlare tunnel tokens) that are associated with Akira ransomware infections. By detecting these indicators much earlier in the attack chain, organizations can inhibit or even obviate file encryption malware deployment. ## Kernel ETW is the best ETW DevFeed: [Kernel ETW is the best ETW]() Original publisher: [Read original article]() Author: John Uhlmann Published: 2024-09-13T00:00:00Z Content type: article Language: en Sources: [Elastic Security Labs]() Topics: [Kernel](), [Logging](), [Security](), [hooks](), [reliability-engineering](), [Windows](), [Process]() Tags: [audit](), [endpoint-protection-security](), [endpoint-security](), [hooks](), [kernel](), [logging](), [microsoft-windows](), [process](), [secure-by-design](), [security](), [software]() ### AI overview This research explains why secure-by-design software should favor kernel-level Event Tracing for Windows (ETW) telemetry over user-mode hooks. It compares the anti-tamper properties and reliability of ETW providers, including process-creation events and security event logging. ### Source excerpt This research focuses on the importance of native audit logs in secure-by-design software, emphasizing the need for kernel-level ETW logging over user-mode hooks to enhance anti-tamper protections. ## Huntress Identifies INC Ransomware Activity and a Repeated Attack Pattern DevFeed: [Huntress Identifies INC Ransomware Activity and a Repeated Attack Pattern]() Original publisher: [Read original article]() Author: Harlan Carvey Published: 2024-05-01T00:00:00Z Content type: article Language: en Sources: [Huntress Blog]() Topics: [ransomware](), [Cybercrime](), [Security](), [incident](), [Windows](), [Command-line interface]() Tags: [analysts](), [command-line](), [defender](), [deployment](), [huntress](), [incident](), [infrastructure](), [microsoft-windows](), [ransomware](), [security]() ### AI overview Huntress describes INC ransomware activity observed in a customer environment and identifies a repeated pattern in the threat actor's intermediate attack stages. Analysts used that pattern to find potentially affected endpoints before ransomware deployment. ### Source excerpt Huntress has observed INC ransomware deployed in the past but recent activity indicates a possible continued shift in/or improvement of tactics employed by these threat actors. ## Doubling Down: Detecting In-Memory Threats with Kernel ETW Call Stacks DevFeed: [Doubling Down: Detecting In-Memory Threats with Kernel ETW Call Stacks]() Original publisher: [Read original article]() Author: John Uhlmann,Samir Bousseaden Published: 2024-01-09T00:00:00Z Content type: article Language: en Sources: [Elastic Security Labs]() Topics: [Security](), [Kernel](), [telemetry](), [Security Information and Event Management (SIEM)](), [Windows](), [Microsoft]() Tags: [detection-engineering](), [kernel](), [microsoft](), [microsoft-windows](), [security](), [siem](), [telemetry](), [threat-intelligence](), [tracing]() ### AI overview Elastic Security 8.11 adds kernel telemetry and ETW call stack-based detections to improve detection of in-memory threats.
