SMM Rootkits

INTRODUCTION The emergence of hardware virtualization technology has led to A rootkit consists of a set of programs that work to subvert the development of OS independent malware such as the Virtual control of an Operating System from its legitimate users [16]. If Machine based rootkits (VMBRs). In this paper, we draw one were asked to classify viruses and worms by a single defining attention to a different but related threat that exists on many characteristic, the first word to come to mind would probably be commodity systems in operation today: The System Management replication. In contrast, the single defining characteristic of a Mode based rootkit (SMBR). System Management Mode (SMM) rootkit is stealth. Viruses reproduce, but rootkits hide. They hide is a relatively obscure mode on Intel processors used for low-level by compromising the communication conduit between an hardware control. It has its own private memory space and Operating System and its users. Secondary to hiding themselves, execution environment which is generally invisible to code rootkits are generally capable of gathering and manipulating running outside (e.g., the Operating System). Furthermore, SMM information on the target machine.

Trojans and Malware on the Internet an Update
Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999. Significant portions of those works are included here in original form. Descriptors: fidonet, internet, password stealing trojan, trojanized system, trojanized application, user behavior, java, activex, security policy, trojan horse, computer virus Attitude Adjustment: Trojans and Malware on the Internet Trojans On the Internet… Ever since the city of Troy was sacked by way of the apparently innocuous but ultimately deadly Trojan horse, the term has been used to talk about something that appears to be beneficial, but which hides an attack within. -

An Adaptive Multi-Layer Botnet Detection Technique Using Machine Learning Classifiers
applied sciences Article An Adaptive Multi-Layer Botnet Detection Technique Using Machine Learning Classifiers Riaz Ullah Khan 1,* , Xiaosong Zhang 1, Rajesh Kumar 1 , Abubakar Sharif 1, Noorbakhsh Amiri Golilarz 1 and Mamoun Alazab 2 1 Center of Cyber Security, School of Computer Science & Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China; [email protected] (X.Z.); [email protected] (R.K.); [email protected] (A.S.); [email protected] (N.A.G.) 2 College of Engineering, IT and Environment, Charles Darwin University, Casuarina 0810, Australia; [email protected] * Correspondence: [email protected]; Tel.: +86-155-2076-3595 Received: 19 March 2019; Accepted: 24 April 2019; Published: 11 June 2019 Abstract: In recent years, the botnets have been the most common threats to network security since it exploits multiple malicious codes like a worm, Trojans, Rootkit, etc. The botnets have been used to carry phishing links, to perform attacks and provide malicious services on the internet. It is challenging to identify Peer-to-peer (P2P) botnets as compared to Internet Relay Chat (IRC), Hypertext Transfer Protocol (HTTP) and other types of botnets because P2P traffic has typical features of the centralization and distribution. To resolve the issues of P2P botnet identification, we propose an effective multi-layer traffic classification method by applying machine learning classifiers on features of network traffic. Our work presents a framework based on decision trees which effectively detects P2P botnets. A decision tree algorithm is applied for feature selection to extract the most relevant features and ignore the irrelevant features. -
Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome
Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome Browser toolbars have been around for years, however, in the last couple of months they became a huge mess. Unfortunately, lots of free software comes with more or less unwanted add-ons or browser toolbars. These are quite annoying because they may: Change your homepage and your search engine without your permission or awareness Track your browsing activities and searches Display annoying ads and manipulate search results Take up a lot of (vertical) space inside the browser Slow down your browser and degrade your browsing experience Fight against each other and make normal add-on handling difficult or impossible Become difficult or even impossible for the average user to fully uninstall Toolbars are not technically not a virus, but they do exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program. Generally speaking, toolbars are ad-supported (users may see additional banner, search, pop-up, pop-under, interstitial and in-text link advertisements) cross web browser plugin for Internet Explorer, Firefox and Chrome, and distributed through various monetization platforms during installation. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that the installed toolbar is a virus. For example, when you install iLivid Media Player, you will also agree to change your browser homepage to search.conduit.com, set your default search engine to Conduit Search, and install the AVG Search-Results Toolbar.
