  • The Most Common Blunder People Make When the Topic of a Computer Virus Arises Is to Refer to a Worm Or Trojan Horse As a Virus
    Trojan And Email Forging 1) Introduction To Trojan&viruses: A Trojan horse, or Trojan, in computing is a generally non-self-replicating type of malware program containing malicious code that, when executed, carries out actions determined by the nature of the Trojan, typically causing loss or theft of data, and possible system harm. The term is derived from the story of the wooden horse used to trick defenders of Troy into taking concealed warriors into their city in ancient Anatolia, because computer Trojans often employ a form of social engineering, presenting themselves as routine, useful, or interesting in order to persuade victims to install them on their computers.[1][2][3][4][5] A Trojan often acts as a backdoor, contacting a controller which can then have unauthorized access to the affected computer.[6] While Trojans and backdoors are not easily detectable by themselves, computers may appear to run slower due to heavy processor or network usage. Malicious programs are classified as Trojans if they do not attempt to inject themselves into other files (computer virus) or otherwise propagate themselves (worm).[7] A computer may host a Trojan via a malicious program a user is duped into executing (often an e-mail attachment disguised to be unsuspicious, e.g., a routine form to be filled in) or by drive-by download. The Difference Between a Computer Virus, Worm and Trojan Horse The most common blunder people make when the topic of a computer virus arises is to refer to a worm or Trojan horse as a virus. One common mistake that people make when the topic of a computer virus arises is to refer to a worm or Trojan horse as a virus.

Social engineering has become a popular strategy to deceive people to run the attacker’s malicious programs. Trojans use this technique to propagate themselves from a computer or a network to others, thus making them hard to prevent.

  • Malware and Its Types
    Malware and its types Malware, short for malicious software, consists of programming (code, scripts, active content, and other software) designed to disrupt or deny operation, gather information that leads to loss of privacy or exploitation, gain unauthorized access to system resources, and other abusive behavior. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. Malware is not the same as defective software — software that has a legitimate purpose but contains harmful bugs (programming errors). Purpose Categorizing malware by its purpose – the intent of the author – can be difficult or impossible. The following categories give us some way to think about malware. Note, however, that some malware might reasonably fit into more than one category. Pranks Many early infectious programs, including a number of MS-DOS viruses, were written as experiments or pranks. They were generally intended to be harmless or merely annoying, rather than to cause serious damage to computer systems. In some cases, the perpetrator did not realize how much harm his or her creations would do. Young programmers learning about viruses and their techniques wrote them simply for practice, or to see how far they could spread. As late as 1999, widespread viruses such as the Melissa virus appear to have been written chiefly as a prank. Many believe the infamous Morris Worm, that shut down a large part of the Internet in 1988 and started a new era in network security, was a prank. Others are not so sure it belongs in this category.

Collen Balasubramanian Kasi 2 Abstract Over the last few decades, consumers have become accustom to the convenience of Automatic Teller Machines (ATMs) to transfer funds between accounts, provide account balance information and to withdraw cash from savings, checking, and other account types. Along with the convenience and ease of locating an ATM through mobile bank apps, there has been a significant increase in ATM fraud across the globe. Consumer confidence in the ATM, bank and credit card issuer is greatly impacted by the perceived level of security in ATM transactions and the technology behind them.

  • Understanding and Blocking the New Botnets White Paper
    Understanding and Blocking the New Botnets April 2008 Researched by Corey Nachreiner, CISSP, Network Security Analyst, LiveSecurity Written by Scott Pinzon, CISSP, Information Security Analyst, LiveSecurity Abstract Botnets are widely regarded as the top threat to network security. This paper explains how botnets have traditionally worked, then contrasts the established model with startling botnet innovations that emerged in 2007 and are continuing to evolve. Examples describe botnets known as Zunker, Gozi, Storm, MayDay, and a kit known as Mpack that helps botmasters easily create malicious web sites. After explaining why the latest innovations make bots a more serious threat than ever, the paper concludes by suggesting defensive countermeasures. Introduction Botnets have existed as a known threat since at least 1999, when the first high-profile Distributed Denial of Service (DDoS) attack occurred.1 By the end of 2007, almost the entire security industry classified botnets at or near the top of any list of threats. Botnets figured prominently in "Top Threats of 2008" prediction pieces, including the Radio Free Security2 podcast from WatchGuard, SANS,3 McAfee's AVERT Labs,4 1 Most experts cite Trinoo or the Tribal Flood Network as the first DDoS attack platforms, as described here: http://www.cert.org/incident_notes/IN-99-07.html. These were Unix-based attacks; the first Windows DDoS attack is widely regarded as powered by WinNuke in April 1999. (http://en.wikipedia.org/wiki/WinNuke ). Denial of Service attacks rose to the mainstream in February 2000, when some of the Internet's most reliable sites were rendered nearly unreachable by Distributed Denial of Service (DDoS) attacks.

  • Metamorphic Virus: Analysis and Detection
    Metamorphic Virus: Analysis and Detection Evgenios Konstantinou Supervisor: Dr. Stephen Wolthusen Technical Report RHUL-MA-2008-02 15 January 2008 Royal Holloway University of London Department of Mathematics Royal Holloway, University of London Egham, Surrey TW20 0EX, England http://www.rhul.ac.uk/mathematics/techreports Abstract Metamorphic viruses transform their code as they propagate, thus evading detection by static signature-based virus scanners, while keeping their func- tionality. They use code obfuscation techniques to challenge deeper static analysis and can also beat dynamic analyzers, such as emulators, by altering their behavior. To achieve this, metamorphic viruses use several metamor- phic transformations, including register renaming, code permutation, code expansion, code shrinking, and garbage code insertion. In this thesis, an in-depth analysis of metamorphic viruses is presented, along with the tech- niques they use to transform their code to new generations. In order to give a better understanding of metamorphic viruses, a general discussion on ma- licious code and detection techniques is given first. Then, the description of several techniques to detect metamorphic viruses is given. A fair number of papers on metamorphic viruses exists in the literature, but no one is a com- plete discussion of all metamorphic techniques and detection methods. This thesis aims at a complete discussion of all metamorphic techniques used by virus writers so far, and all detection techniques implemented in antivirus products or still experimental. It accomplishes this by an in-depth research on malware and metamorphic viruses, through the existing literature. Due to space and time limitations, an exhaustive discussion was not possible in this thesis.

Malware : Viruses, Logic bombs Q.What is computer security means? Ans. Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The strategies and methodologies of computer security often differ from most other computer technologies because of its somewhat elusive objective of preventing unwanted computer behavior instead of enabling wanted computer behavior. Q.What is Data Security? Ans. Data security is the means of ensuring that data is kept safe from corruption and that access to it is suitably controlled.
