Microsoft has announced a new free-to-use initiative aimed at uncovering forensic evidence of sabotage on Linux systems, including rootkits and intrusive malware that may otherwise go undetected.

Jul 03, 2020 Malwarebytes for Mac protects against malware - including trojans, spyware, keyloggers, viruses and more - as well as adware and potentially unwanted programs. Jul 26, 2016 MalwareBytes Anti-Malware is sufficient for some, it'll deal with a lot of Mac malware you'd actually need to worry about. Note that this is not a 'solution' since Apple added SIP to El Capitan for security purposes and really should be enabled. Moreover, it's likely that any future beta will turn it back on by default. Also, csrutil has.
The cloud offering, dubbed Project Freta, is a snapshot-based memory forensic mechanism that aims to provide automated full-system volatile memory inspection of virtual machine (VM) snapshots, with capabilities to spot malicious software, kernel rootkits, and other stealthy malware techniques such as process hiding.

This occurs when the copy of the macOS Catalina Installer app used has gotten corrupted somehow. To rectify this, use Catalina Patcher to download a fresh copy of the Catalina installer, then re-create an installer volume and/or retry the installation. The Zoom application does not.

The project is named after Warsaw’s Freta Street, the birthplace of Marie Curie, the famous French physicist who brought X-ray medical imaging to the battlefield during World War I.
“Modern malware is complex, sophisticated, and designed with non-discoverability as a core tenet,” said Mike Walker, Microsoft’s senior director of New Security Ventures. “Project Freta intends to automate and democratize VM forensics to a point where every user and every enterprise can sweep volatile memory for unknown malware with the push of a button — no setup required.”
The objective is to infer the presence of malware from memory, at the same time gain the upper hand in the fight against threat actors who deploy and reuse stealthy malware on target systems for ulterior motives, and more importantly, render evasion infeasible and increase the development cost of undiscoverable cloud malware.
To that effect, the “trusted sensing system” works by tackling four different aspects that would make systems immune to such attacks in the first place by preventing any program from:
“When attackers and defenders share a microarchitecture, every detection move a defender makes disturbs the environment in a way that is eventually discoverable by an attacker invested in secrecy,” Walker noted. “The only way to discover such attackers is to remove their insight into defense.”
Open to anyone with a Microsoft Account (MSA) or Azure Active Directory (AAD) account, Project Freta lets users submit memory images (.vmrs, .lime, .core, or .raw files) via an online portal or an API, post which a detailed report is generated that delves into different sections (kernel modules, in-memory files, potential rootkits, processes, and more) that can be exported via JSON format.

Microsoft said it focused on Linux due to the need for fingerprinting operating systems in the cloud in a platform-agnostic manner from a scrambled memory image. The increased complexity is given the large number of publicly available kernels for Linux. This initial release version of Project Freta supports over 4,000 Linux kernels, with Windows support in the pipeline.
It’s also in the process of adding a sensor capability that allows users to migrate the volatile memory of live VMs to an offline environment for further analysis and more AI-based decision-making tools for threat detection.
“The goal of this democratization effort is to increase the development cost of undiscoverable cloud malware toward its theoretical maximum,” Walker said. “Producers of stealthy malware would then be locked into an expensive cycle of complete re-invention, rendering such a cloud an unsuitable place for cyberattacks.”

Check compatibility
You can upgrade to OS X El Capitan from OS X Snow Leopard or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8.8GB of available storage space.
MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
MacBook Air introduced in late 2008 or later MacBook Pro introduced in mid 2007 or later Mac mini introduced in early 2009 or later iMac introduced in mid 2007 or later Mac Pro introduced in early 2008 or later Xserve models introduced in early 2009
To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with OS X El Capitan, the installer will let you know.
Make a backup![]()
Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
Get connected
It takes time to download and install OS X, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.
Download OS X El Capitan
For the strongest security and latest features, find out whether you can upgrade to macOS Catalina, the latest version of macOS.
If you still need OS X El Capitan, use this link: Download OS X El Capitan. A file named InstallMacOSX.dmg will download to your Mac.
Install the macOS installerMalwarebytes For El Capitan
Double-click the downloaded file to open a window showing its contents. Then double-click the file within, named InstallMacOSX.pkg.
Follow the onscreen instructions, which will guide you through the steps necessary to install.
Begin installation
After installation of the installer is complete, open the Applications folder on your Mac, then double-click the file named Install OS X El Capitan.
Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.
Allow installation to complete
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both OS X and related updates to your Mac firmware.
