I must say there is something deeply ironic about all this effort being put into improving math at the same time the .NET DataFrame project is essentially dead. (A DataFrame being the best way to do math over series of data.)
This is great, but puhleeaaaaase make it so that F12 on a .NET Standard library member will forward to an actual implementation and not the useless reference assemblies. Based on my tests it does not do this currently. I think the best choice would be to pick the latest installed .NET Core version that supports the .NET Standard version but there could also be a mechanism to pick which .NET Core version is used in the decompilation.

Fortunately I wasn't using anything from the library, so I was able to remove it from the XLA references entirely. I guess, an extension of divo' suggested best practice would be for testing to check the XLA on all the target Office versions (not a bad idea in any case).
What is the best way to defend against this attack? As demonstrated above, using an EDR with signature-based detections to block Mimikatz is inadequate. There are a few things your organization can do to help prevent these attacks. Ideally, all end-of-life Windows operating systems should be decommissioned and upgraded to currently supported operating systems. Newer Windows operating systems disable WDigest by default, helping protect against the dumping of plaintext passwords using these methods. However, this is not always possible for some organizations, and attackers can still use the above methods to dump NTLM hashes which can then be cracked or used in pass-the-hash attacks to perform lateral movement. Another important defense is to restrict local administrative access as much as possible. Besides these two general rules, the following are some methods that can be used to prevent and detect these attacks.
If an organization disables WDigest and creates alerting on WDigest being re-enabled, this forces an attacker to crack NTLM hashes or use pass-the-hash techniques. Disabling and/or alerting on pass-the-hash techniques then makes LSASS dumping attacks far less effective, as it reduces the attack surface of LSASS dumping to the ability to crack dumped NTLM credentials. Disabling/preventing pass-the-hash techniques is a complex topic and will not be covered in depth by this post. For further information, check out these white papers.
In addition to biometric authentication, Windows Hello supports authentication with a PIN. By default, Windows requires a PIN to consist of four digits, but can be configured to permit more complex PINs. However, a PIN is not a simpler password. While passwords are transmitted to domain controllers, PINs are not. They are tied to one device, and if compromised, only one device is affected. Backed by a Trusted Platform Module (TPM) chip, Windows uses PINs to create strong asymmetric key pairs. As such, the authentication token transmitted to the server is harder to crack. In addition, whereas weak passwords may be broken via rainbow tables, TPM causes the much-simpler Windows PINs to be resilient to brute-force attacks.
On the other hand Ars Technica panned the new Tablet mode interface for removing the charms and app switching, making the Start button harder to use by requiring users to reach for the button on the bottom-left rather than at the center of the screen when swiping with a thumb, and for making application switching less instantaneous through the use of Task View. Microsoft Edge was praised for being "tremendously promising", and "a much better browser than Internet Explorer ever was", but criticized it for its lack of functionality on-launch. In conclusion, contrasting Windows 8 as being a "reliable" platform albeit consisting of unfinished concepts, Windows 10 was considered "the best Windows yet", and was praised for having a better overall concept in its ability to be "comfortable and effective" across a wide array of form factors, but that it was buggier than previous versions of Windows were on-launch. ExtremeTech felt that Windows 10 restricted the choices of users, citing its more opaque setting menus, forcing users to give up bandwidth for the peer-to-peer distribution of updates, and for taking away user control of specific functions, such as updates, explaining that "it feels, once again, as if Microsoft has taken the seed of a good idea, like providing users with security updates automatically, and shoved the throttle to maximum." Windows 10 has also received criticism because of deleting files without user permission after auto updates.
Once you have installed the distro of your choice, launch it and set up a non-root user if you have not already. Debian and Ubuntu will configure this automatically at first launch, as should Alpine if you installed it from the Store. If the whoami command returnes "root", then you will want to add a non-root user. For Alpine or Fedora, use adduser myusername to create a new user. On Alpine, this should prompt for the new password. On Fedora, you will additionally need to passwd myusername and enter the password you want to use. (If your Fedora does not have passwd, then you will need to first dnf install passwd cracklib-dicts).
Any method of learning that suits you and your learning style should be considered the best way to learn. Different people learn well through different methods. Some individuals may prefer taking up online courses, reading books or blogs, or watching YouTube videos to self-learn. And some people may also learn through practice and hands-on experience. Choose what works best for you!
Organized around concepts, this Book aims to provide a concise, yet solid foundation in C# and .NET, covering C# 6.0, C# 7.0 and .NET Core, with chapters on the latest .NET Core 3.0, .NET Standard and C# 8.0 (final release) too. Use these concepts to deepen your existing knowledge of C# and .NET, to have a solid grasp of the latest in C# and .NET OR to crack your next .NET Interview.
When it comes to ransomware of all types, often the best thing we can do as defenders is to make every effort to stay one step ahead of the threat actors, even when the journey proves complex and arduous.
Linux, like windows, iOS, and Mac, is an operating system that helps one to use or utilize old and outdated computer systems such as Firewall, router, backup server, etc. It makes computer systems more secure than Windows and does not require any use of Anti-Virus Programs. It is becoming increasingly popular as the OS for servers because it comes with the capabilities to heavily encrypt and protect all of a computer's data. The above given are all important questions along with answers related to Linux that were recently asked in Interviews. It will give you a better understanding of all the important topics related to Linux and will help you to crack the interviews.
This document is the QTI 3.0 Best Practices and Implementation Guide (BPIG). The BPIG consists of six sections describing the various structures and features of QTI and how to best implement them in your assessment products.
This document contains examples of QTI 3. Many of the examples are illustrated by screenshots or rendered views of the items, which are designed to illustrate how a system might implement the specification. This is a guide to best practices for QTI 3 implementation, and examples are for illustrative purposes.
This Best Practices and Implementation Guide is organized to provide an introduction to implementing QTI, constructing a QTI 3 open standards-based solution, a description of the Item and Test models at the core of QTI content, how the content interacts with the Personal Needs and Preferences of students, and how packaging brings it all together. Example markup, screenshots of rendered QTI, and details about best practices in adopting the standard are provided in this best practices guide.
The sequence and structure of any valid QTI 3 file (tests, parts, sections, items, and stimulus) included in a content package is regulated by its associated XML Schema Definition (XSD). QTI 3 does leverage a number of W3C standards (HTML, MathML, CSS, SSML to name a few) which cannot be completely validated using the 1EdTech validators. When using these related standards, the expectation is that implementers will follow the best practices recommended for each of the standards. 2b1af7f3a8
