Unfortunately, malicious code writers also use these methods to prevent their attack mechanisms from being detected by antimalware tools. The 2020 SolarWinds attack is an example of hackers using obfuscation to evade defenses.
The attackers are mostly involved in exploring vulnerabilities in the legitimate software that are already installed in the machine such as flash player, web-browser, PDF viewer and Microsoft office to exploit and load a script directly into the main memory without even touching the local file systems (Pontiroli & Martinez, 2015; Rani et al., 2019). In Windows Operating Systems, two most powerful tools and. NET framework are already installed which attacker can use to exploit the vulnerability, one is WMI (Windows Management Instrumentation) (Graeber, 2015) and second is PowerShell. WMI came into the limelight of the cybersecurity community when it was discovered that it is used maliciously as a component in the suite of exploits by Stuxnet (Falliere et al., 2011; Farwell & Rohozinski, 2011). Since then, WMI has been gaining popularity amongst the attackers, because it can perform system reconnaissance, AV/VM (Virtual Machine) detection, code execution, lateral movement, persistence, and data theft. Similarly, in the case of PowerShell, it is a highly flexible system shell and scripting platform for the attacker to provide all the features in the different stages of an intrusion. Since, it can also be used to bypass anti-virus detection, maintain persistence or infiltrate data. For example: In 2016, a hacker group infiltrates into the DNC (Democratic National Committee) with fileless malware. In this incident, the PowerShell and WMI were used as the attack vectors (Report, 2016).
In recent time, malware developers have adopted the high-level language in the development of the malicious codes that have changed the malware industry. After the release of Microsoft .Net framework, it became the center of attraction for all the windows software developers and unintentionally revolutionized the malware industry (Tian et al., 2019b; Tian et al., 2019c). It gives the malware writers a new and powerful arsenal equipped with all the features to make a malware undetected and stay ahead of the anti-virus software. With the use of this framework, malware creator may easily interact with the operating system and exploit vulnerabilities with the entire catalog of products with the help of the framework (Patten, 2017; Pontiroli & Martinez, 2015; Tian et al., 2019d; Bhasin et al., 2018). The attacker uses a tool like PowerShell to coordinate attacks with the help of existing toolkits such as meterpreter (About the Metasploit Meterpreter, 2019), SET (Social Engineering Toolkit) (Pavković & Perkov, n.d.), or the Metasploit Framework including an extensive list of modules that are already built-in and ready to use for the purpose of plotting additional attacks (Tian et al., 2018).
Unlike traditional file-based malware attacks, instead of using real malicious executables, it leverages trusted, legitimate processes i.e. LOLBins (Living off the Land Binaries) (Living Off The Land Binaries And Scripts - (LOLBins and LOLScripts), 2019) and built-in tools of operating systems to attack and hide. The detailed comparisons between traditional file-based malware and fileless malware are mentioned in the Table 2 (Afianian et al., 2018). In this section, the formal definition of the fileless malware and execution techniques along with the system tools, is discussed. The section also elaborates on the infection technique used by such malware with attack vectors, as shown in Fig. 1.
Although there was a marked increase in the number of fileless malware attacks at the beginning of 2017, the success of this technique seems to be waning. The 2017 surge was due to the discovery and definition of the technique and its formulation into hacker toolkits, which made the methodology easy to implement.
Updating your project solution to the latest framework version takes some time, but it can save time and money in the long run. And this because the latest framework updates include security patches for the holes that hackers and malware know to look for.
Malicious PowerShell scripts are a key ingredient to many fileless malware. Windows PowerShell is a built-in tool based on the .NET framework comprising a command-line shell, an interface that lets users access services of the operating system (OS), and a programming language that can be used to create scripts. PowerShell is designed to automate system administration tasks, such as view all USB devices, drives, and services installed in the system, schedule a series of commands and set it in the background, or terminate processes (like Task Manager). PowerShell is also designed to enable administrators to seamlessly manage the configurations of systems and servers as well as the software or services and the environments they run on.
Are we forgetting that 80% of people use a CELL PHONE to surf the net. A constant server connection of any kind means people are going to need to use data in the same manner as streaming a movie just to use a website. This is a really bad idea. NO one is going to use a website that just viewing takes a constant stream of data. How many of you, like myself, open a window and just leave it up and walk away form it Not to mention that you are just leaving an open line for hackers to access the server. Do you really want to make your application dependent on something that can only handle a certain amount of users and is guaranteed to crash or slow with unexpected jumps in users It seems like Blazor is just a way to set yourself up to fail. Their is so much involved in building any ASP.NET app from razor, C#, Entity Framework, html,css, JS, forget any Typescript. As far as I am concerned it is just another thing to learn that is a HUGE security risk and a data hog which is going to piss off your users. We need to think of these frameworks and languages as tool to solve problems in the real world. Their is no magic language that is going to be the best solution for every problem, use the right tool for the job. Unfortunately as a developer that means learning as much as you can but then also knowing when the language you work in, is not going to be a good fit for a certain application. All these developers that think they are so smart always seem to overlook the biggest part of any app, THE END USER!!!! 153554b96e
