Computers are always at risk when accessing the internet even with a top of the line anti-malware program installed. According to a study from the Web security company Dasient, between 2009 and 2010, the number of malicious websites doubled (Dasient via Chang, Venkatasubramanian, West, & Lee, 2013). This poses a difficult front for battling against malware. As long as the number of malware increase, anti-malware needs to keep adapting to the changing times. Another study, conducted in September 2014 by AV-Comparatives, showed that only one of the 23 anti-malware programs they tested have a "real-world protection test" score of 100% with only 5 false positives. Conversely, seven of them allowed at least 5% of the 602 malware tested …show more content…
Not only is malware becoming more difficult to deobfuscate, but it 's also utilizing new functions that are difficult to detect by these means. Therefore, anti-malware researchers should focus on other forms of detection such as CPU analyzers, holograpy, eigenvirus detection, differential fault analysis, the growing grapes method, and whitelist protection.
Current Malware and Ineffective Methods of Detection Malware is getting past deobfuscation methods utilizing packaging. A survey conducted in 2006 by Black Hat indicated 92 percent of malware has gone through a packer. Other surveys indicate a number closer to 50 percent (O 'Kane et al., 2011). Despite this discrepancy in numerical data, it still shows that packaging is the most used form of obfuscation. To combat this, many anti-malware services attempt to pinpoint specific packers using signature analysis. According to O 'Kane and his team at Queen University, this is only as good as the comprehensiveness of the unpacker 's database (2011). Therefore, anything that is not in the signature database can easily bypass the anti-malware software. Another method of detecting these packaged files is through entropy analysis. When a file is packaged, the level of entropy of these files is increased a large amount. O 'Kane et al. point to a study of the PE-Probe entropy analysis software which has a detection rate of 99.6 percent for packed files (2011). However, this is only detecting that a file was
As we know virus protection software is a code written by one of the programing languages that we know. This code works as a search engine looking for infected files in the entire system or specific locations on the system. The idea depends on two important factors which are, search engine and viruses’ data base. The following scenario explains how people get viruses and how virus protection software works.
Bashir, Khan, and Bhutto (2015) propose a framework for forensic triage clustering techniques that compare the case evidence against a database of blacklisted information containing information over prior malicious attacks. The framework consists of five phases: (1) identification and isolation of the machine under investigation; (2) data imaging, memory dump, log files, and other system activities; (3) extraction of potential evidence files; (4) triage comparison against the blacklist database; and (5) reporting. The blacklist database contains the history of previous malicious malware or cyber-attacks and allows investigators the ability to use clustering to single out any files matching known attack information. Testing successfully showed a reduction in files needing analysis and provided efficiently accessible information on
These days, there are thousands of different viruses and malware on Internet. Like the writers of viruses and other malicious code are many and diverse, and their reasons and motives that drive people to create a virus are as wide-ranging as themselves.
As malware attacks continue to grow in strength, numbers and complexity, it is critical that organizations are taking measures to prevent attacks and to minimize the damage when attacks do occur. This paper will briefly discuss what malware is, the damage it can cause and how it has evolved over the years. Since malware attacks are constantly changing and adapting, a proactive approach is necessary for an organization to remain secure. A proactive approach to network security involves analyzing current and future malware threats, educating employees, and developing a malware response
Malwares are mischievous programs crafted to agitate or forbid normal operations to gather selected information which may lead to loss of privacy through
Lawton, G. (2008). Is it finally time to worry about mobile malware? Computer, 41(5), 12-14.
The majority of the customer’s in the cyber security industry has multiple cyber related business like antivirus, providing network hardware, providing security services, performing audits and assessments and risk advisory services. Company’s like Palo Alto and McAfee are entering into malware analysis with very less or no profit margin set to attract more customers. This affects the quality of the product and poses a critical challenge for FireEye.
To understand the business of malware, one must understand how malware has evolved in the past twenty-five years. Malware, which includes all kinds of malicious software, was originally created to show the weaknesses of computers. The first type of malware, created in 1986, was a virus called “Brain.A. Brain.A was developed in Pakistan, by two brothers - Basit and Amjad. They wanted to prove that PC is not secure platform, so they created virus that was replicating using floppy disks” (Milošević). Even today malware is still used to check the security of machines.
There are simple steps that can be taken to make your computer safer. Every computer connected to a network is at risk of being attacked, but knowledge of each threat that can occur and knowing how to minimize your security risk can help in the setup of a new computer and the ones that you already have. With knowing how to prevent your computer from being attacked will help you in setting up accounts for social media as well because you will be able to tell what and who is harmful to your account.
The computer virus employees of Symantec Corp. are never able to enjoy a finished product. They are constantly collecting viruses and suspicious codes to analyze the way they work and to find a solution to prevent these viruses form damaging the public’s computers. They are determined to provide their consumers with updated versions of anti-viruses for their computers. At the Symantec lab, they have a box, which has all dangerous types of viruses that needs or be disposed of. Vincent Weafer has been a part of Symantec since 1999. In 1999, there were only a few employees at Symantec and that there were only a few viruses spread out through months compared to how it is now. Nowadays there are about 20,000 viruses monthly spread

As many have heard, Macintosh Computers, and more in general Apple Inc., is beginning to really take flight in consumer households. The overwhelming numbers of available viruses to Windows computers, phones, and Android devices surpasses the millions. In fact, in April of 2012, Symantec released a report noting its latest Virus definitions file that contained 17,702,868 separate signatures (Bott). This number seems quite ridiculous regarding the amount of viruses available. However, the same report given by Symantec 8 days earlier only reported 17,595,922 virus definitions, meaning that 106,946 definitions were
With the prevalence of zero-day exploits, malvertising and numerous other advanced threats, it can take days for AV software to identify and begin screening for new threats, which often too late.
Every day we are prone to threats against our lives that may harm us in many ways, in the real world and cyber world. In the cyber realm, we have a big issue with something called malware; malware is malicious software that comes in many forms. It may attack in many ways at any time or place; that is why there is a lot of research going into figuring out how malware works.
