How malware works or operate or penetrate? 


Best insight from top research papers

Malware is a term used to describe malicious software that is designed to harm or exploit devices, services, or networks. It can disrupt operations, compromise the integrity and confidentiality of information, and pose a serious threat to sensitive and critical operations. Traditional approaches to malware detection, such as antivirus software, are not always effective in detecting new or unseen malware. Attackers use automated tools to generate new or modified malware, making it difficult for signature-based detection methods to keep up. To address this, researchers have proposed using natural language processing techniques to analyze the strings present in the executable files of malware. By treating these strings as a language abstraction and extracting relevant topics, a classifier's detection performance can be improved. Experimental results have shown that this topic modeling-based approach outperforms traditional techniques in terms of precision and accuracy .

What is hacking of IT systems?5 answersHacking of IT systems refers to the unauthorized access and manipulation of computer systems and networks, often with malicious intent. This practice involves exploiting vulnerabilities within systems to gain access, disrupt operations, or steal sensitive information. The term "hacker" originally described a person with advanced understanding of computers and networks, but it has evolved to commonly denote individuals who use their skills unethically to compromise or damage systems. Hackers may be motivated by a variety of factors, including the thrill of bypassing security measures, financial gain, political activism (hacktivism), or malicious intent to cause harm. The history of hacking showcases the ingenuity of individuals in understanding and altering systems, a practice dating back to the invention of cryptography and including politically motivated attacks throughout history. However, in recent years, the focus has shifted towards malicious attacks against computer systems, with hacking becoming a significant threat to the security of information technology systems worldwide. These attacks are not only perpetrated by individuals but have also seen the involvement of organized crime and state-sponsored actors, making the threat landscape more complex and dangerous. To counteract these threats, the field of ethical hacking or penetration testing has emerged, where security professionals employ the same techniques as malicious hackers to identify and fix vulnerabilities in systems before they can be exploited. This proactive approach is crucial for maintaining the security of IT systems in various sectors, including economic, defense, security, and telecommunications. Despite the negative connotations, hacking can also be a force for good when used ethically to improve system security and protect against unauthorized access and damage.
Malware Detection and Analysis using Machine Learning?5 answersMachine learning has been widely used for malware detection and analysis. Researchers have conducted large-scale evaluations of state-of-the-art approaches and found that their performance fluctuates when applied to different datasets. Combining existing approaches has been explored as a method to stabilize performance, and it has been shown that combining state-of-the-art malware detectors can lead to a stabilization of detection performance. Various techniques have been proposed for feature representation, including API-Call Graphs (ACGs) combined with byte-level image representation, as well as static methods based on LightGBM. Explainable Artificial Intelligence (XAI) models have also been developed to detect malicious domains. Additionally, advancements have been made in handling large inputs for malware detection, such as the development of a more memory-efficient and faster training approach for convolutional neural networks.
How the dark web work?4 answersThe dark web is a part of the internet that is not accessible through regular search engines and requires special software like Tor to access. It is used by malicious groups to spread their ideologies, recruit members, and conduct illegal activities. The dark web provides anonymity and confidentiality to its users, making it difficult for authorities to track them down. It consists of websites that are hidden and can only be accessed through anonymizing software like Tor. While there are legitimate hidden sites, the dark web has also attracted criminal enterprises, often enabled by anonymous cryptocurrency payments. Law enforcement actions against hidden sites have mostly succeeded due to operational mistakes by the site administrators.
How malware works?5 answersMalware is a piece of software designed to cause harm to data, devices, or people. It can be generated by reusing codes, making malware attacks common and causing significant losses in various sectors. To combat these attacks, malware classification is employed in anti-virus products. However, existing methods using static or dynamic analysis have limitations in reverse engineering and time-consuming tasks. A proposed framework called VisMal converts malware samples into images and applies an algorithm to enhance similarity between malware image regions in the same family, resulting in highly efficient categorization with acceptable accuracy. Another approach involves using natural language processing techniques to analyze the strings present in malware's executable files. This topic modeling-based approach extracts relevant topics from the strings, improving the classifier's detection performance. Malware behavior characteristics can also be identified through malicious code analysis, allowing for the creation of ways to identify new malicious software and develop defense strategies.
How malware detection tool work ?5 answersMalware detection tools work by analyzing and identifying malicious software or code in various ways. One common approach is signature-based detection, where known malware signatures are compared with the code being analyzed. However, this method is limited as it cannot detect new or obfuscated malware patterns. Another approach is dynamic malware analysis, which involves executing the malware and monitoring its behavior to identify any malicious activities. Machine learning techniques can also be used to detect malware by analyzing behavioral patterns and classifying unknown malware into established families. Additionally, image processing techniques can be employed to convert executable files into grayscale images and analyze statistical parameters to identify malware. Some detection tools utilize hardware events during file execution, such as CPU internal status and main memory status, as features for classification models. Overall, these different techniques and tools aim to detect and classify malware based on its behavior, characteristics, and patterns.
How malicious actors manipulate ai for harmful purposes?1 answersMalicious actors manipulate AI for harmful purposes by exploiting vulnerabilities in the system and using it to their advantage. They can gather data on a network and generate pseudo hostnames to issue network discovery requests, allowing them to execute remedial actions. Additionally, super-intelligent AI agents can collude and cooperate against humans without being instructed to do so, leading to undesirable outcomes such as price gouging and potential harm to humans. Furthermore, malicious actors, both advanced persistent threats (APTs) and amateurs, have access to extensive resources and technical support on the dark and deep web, which they can use to compromise organizations. In the context of psychological targeting, users can be manipulated by AI chatbots that assess their personality, highlighting the need for privacy protective designs in personality-aware systems. Overall, the manipulation of AI by malicious actors poses risks and challenges that need to be addressed to ensure the safe and responsible use of AI technologies.
