Microsoft Launches Free Linux Forensics and Rootkit Malware Detection Service

Microsoft has declared a new free-to-use initiative aimed at uncovering forensic evidence of sabotage on Linux units, together with rootkits and intrusive malware that might usually go undetected.

The cloud offering, dubbed Task Freta, is a snapshot-based mostly memory forensic mechanism that aims to offer automatic full-method risky memory inspection of virtual machine (VM) snapshots, with abilities to place malicious software program, kernel rootkits, and other stealthy malware tactics these as approach hiding.

The task is named right after Warsaw’s Freta Avenue, the birthplace of Marie Curie, the well-known French physicist who introduced X-ray clinical imaging to the battlefield throughout Environment War I.

“Modern malware is complex, subtle, and created with non-discoverability as a main tenet,” said Mike Walker, Microsoft’s senior director of New Stability Ventures. “Undertaking Freta intends to automate and democratize VM forensics to a level exactly where each and every consumer and every single enterprise can sweep risky memory for mysterious malware with the push of a button — no set up expected.”

The goal is to infer the presence of malware from memory, at the very same time attain the higher hand in the fight from threat actors who deploy and reuse stealthy malware on concentrate on programs for ulterior motives, and a lot more importantly, render evasion infeasible and maximize the progress expense of undiscoverable cloud malware.

To that outcome, the “trusted sensing program” is effective by tackling four distinctive elements that would make techniques immune to this kind of assaults in the to start with spot by protecting against any software from:

  • Detecting the presence of a safety sensor prior to putting in alone
  • Residing in an location that’s out of watch of the sensor
  • Detecting the sensor’s operation and accordingly erasing or modifying by itself to escape detection, and
  • Tampering with the sensor’s features to trigger sabotage

“When attackers and defenders share a microarchitecture, every detection shift a defender makes disturbs the natural environment in a way that is ultimately discoverable by an attacker invested in secrecy,” Walker noted. “The only way to explore these kinds of attackers is to take out their perception into defense.”

Open to anybody with a Microsoft Account (MSA) or Azure Lively Listing (AAD) account, Venture Freta lets end users post memory photographs (.vmrs, .lime, .main, or .raw information) by way of an on-line portal or an API, publish which a thorough report is produced that delves into unique sections (kernel modules, in-memory files, probable rootkits, procedures, and additional) that can be exported by using JSON structure.

Microsoft said it concentrated on Linux because of to the need to have for fingerprinting functioning techniques in the cloud in a platform-agnostic fashion from a scrambled memory impression. The amplified complexity is specified the significant number of publicly offered kernels for Linux. This first launch edition of Challenge Freta supports around 4,000 Linux kernels, with Home windows assistance in the pipeline.

It’s also in the method of incorporating a sensor capacity that permits consumers to migrate the unstable memory of live VMs to an offline atmosphere for additional evaluation and much more AI-dependent conclusion-making applications for danger detection.

“The goal of this democratization hard work is to raise the enhancement expense of undiscoverable cloud malware towards its theoretical highest,” Walker said. “Producers of stealthy malware would then be locked into an pricey cycle of entire re-invention, rendering this sort of a cloud an unsuitable area for cyberattacks.”
