...Ransomware Discuss the threat When infected restricts you to access to a computer system. This will become more refined in its targets and methods. Experts predict that the variants of ransomware that hurt the security software that are installed within a computer may particularly target the endpoints which sign up with cloud-based storage solutions like Google Drive, Dropbox, OneDrive and many more. On detecting the endpoint, ransomware will exploit the stored personal credentials of the logged-in user and will even infect the cloud storage that is backed up. McAfee has warned that ransomware attackers will try out as many ways possible to shell out ransom payments from their victims. Degree of damage The most advanced and most damaging ransomware in the wild at the moment, specifically targeting U.S. businesses and individuals. It's a $70 million per year criminal enterprise. Its magnitude is now confirmed by law enforcement. Some quick math shows $18,145 in costs per victim, caused by network mitigation, network countermeasures, loss of productivity, legal fees, IT services, and/or the purchase of credit monitoring services for employees or customers. As you can see, the total costs of a ransomware infection goes well above just the ransom fee itself, which is usually around $500 but can go up to $10,000. What it attacked Ransomware is a type of malware that infects a computer and restricts a user’s access to the infected computer. This type of malware...

...used to access online accounts. He also admitted to impersonating payroll officers in conversations he had with ADP, which is based in New Jersey. The case resulted from a collaboration between the banks and the Federal Bureau of Investigation against Nwaki, a.k.a. Shawn Conley, who was arrested in December on charges of wire fraud conspiracy, wire fraud, aggravated identity theft, and conspiracy to gain unauthorized access to computers. Each count, to which Nwaki pleaded guilty, carries a maximum sentence of 20 years in prison and a maximum fine of $250,000; sentencing is set for Aug. 15, 2012. According to court records, Nwaki and six co-conspirators, between August 2000 and June 2010, worked across three continents to launch phishing attacks through spoofed websites designed to mimic banks and payroll processors such as ADP. When online users visited the spoofed pages, they were asked to provide confidential personal and financial information, such as dates of birth, Social Security numbers, mothers' maiden names, and online account user names and passwords. Having obtained log-in credentials and answers to commonly-asked security questions, the hackers accessed online accounts to make unauthorized transfers to accounts they controlled and/or wired...

...Types of System Attacks Bryan Francia Coleman University Abstract This paper is a brief overview of different types of Information Security System attacks. Without Security measures or system controls, your data could be stolen, your computer hijacked or corrupted, or your network destroyed. There are so many different methods attackers use, attempting to cover down on all of them in a two page paper would be pointless, but will briefly cover some of the more common types of network attacks. Without a security plan, your data is vulnerable to any of the following types of attacks. There are active attacks and there are passive attacks. An active attack means the information is changed with intent to corrupt or destroy the data or network, while a passive attack generally means your information is being monitored. Eavesdropping is when an attacker who has gained access to data paths in your network listens or reads the traffic. It is known as sniffing or snooping. Eavesdroppers have the ability to monitor networks because the majority of network communications occur in an unsecured format and is generally the biggest problem that administrators face in an enterprise. After an attacker has accessed your data, he or she may alter it. This is referred to as Data modification. It is possible for an attacker to modify the data in a packet while in transit without the knowledge of the sender or receiver. This is especially important in business, as you would not want...

...Attack Prevention Paper The article that was chosen for the review was Simple Cross-Site Attack Prevention by Florian Kerschbaum. This article covers what a cross-site attack is, how attackers use them and how vulnerable web applications can be. In this paper we will look at what the problem is as the original author sees it. We will also look at resolutions that could be done to prevent this kind of attacks. In this article the author explains how a simple cross-site attack can take place and goes on to explain what a solution for this problem is. This article starts out by explaining what a cross-site attack is and how they take place with some examples. According to Kerschbaum “A reflected cross-site scripting attack or cross-site request forgery attack occurs when a user follows a malicious link. This link has been tainted with some input that exploits vulnerability on the target web site, such that a script can execute in the security context of the user’s browser and the target web site” (Kerschbaum, n.d., para. 13). In this article the author clearly states the problem and the seriousness of the problem. The author covered the information from a technical perspective but was able to describe the problem in every day terms so that the end users could understand the issues and the solution to the issue that would resolve the problem. These examples are thing that we still see today from the fake e-mails that send a person out to a site for them to login...

...Attacks On AIS Introduction The more modern technology advances it appears vulnerabilities continuously exist in software used on networks. Hackers or automated information system (AIS) attackers gain access to system networks by manipulating those vulnerabilities. Attackers accomplish this by exploiting operating systems at the root level (Balga, Iftode, & Chen, 2008). Although there are protective measures available, businesses, particularly small businesses, are the most susceptible to these attacks. The following paragraphs will provide an argument based on why businesses are liable for loss when attackers attack their AIS. AIS The assembly of firmware, hardware, and software makes up the automated information system or AIS. It is here where computers store information, such as computations and communications. Businesses and governmental agencies benefit from the use of an AIS. The benefits are time and cost efficient; however, the greater the benefit the greater the risk of attacks. Businesses are losing billions of dollars annually because of these attacks especially when there is no preventive measures in place (Balga, Iftode, & Chen, 2008). Without preventive measures, attackers forge Internet Protocol (IP) Addresses, which causes the victims of the attack to attack other victims. The source of the attack remains unidentifiable. Another type of attack is through user accounts. Networks use authentication information, such as user ID and passwords...

...Attacks11/23/14 China’s Cyber Attack on Google A majority of the population in the United States has used Google as a search engine to find information. It is often easy to think that whatever information you want to find on the internet can be found through Google. However, in China, that wasn’t always the case. In 2006, Google extended its company to China in hopes to help digitally connect China’s population to more resources over the internet. Unfortunately, opening up Google in China led the company to experience cybersecurity breaches that affected many companies and people. The following paper will discuss one of China related cybersecurity attacks on Google and how the breach might have occurred based on investigative reports. Additionally, the paper will include information on known or suspected losses of confidentiality, integrity, and the availability of information systems. Lastly, I will discuss the improvements Google made to improve its cybersecurity measures. The history of Google in China begins in 2006, when the company decided to launch its services to China. Although the intention for Google in China was to provide the Chinese with more resources for information, China still had several regulations on censorship. Whether the censorship regulations fueled the hackers to attack Google is unknown, but it is suspected (Arrington, 2010). Recent reports on cybersecurity breaches related to China show that China has been consistently responsible for...

...Responses to Attacks Responding to Attacks on Computers Threats to an organization’s computer systems come from a variety of sources. The motivations for computer attacks are as different as the attackers themselves. For example, a group of organized criminals may carefully execute an attack on your computer system, hoping to gain confidential information they can sell to competitors or use to extort money from your organization. Industrial spies may try to steal a company’s secret plans for a new product. Cyber-terrorists with political or religious motivations may attack an organization or government with which they disagree. Amateur hackers may access systems to plant their virtual flag and earn merit badges in the hacker community. Occasionally, bored teenagers may hack into a system just to prove they can. Cybercrimes have a direct impact on privacy. An organization’s failure to adequately protect information can lead to disaster, so the necessity for good data security is absolute, and a fiduciary responsibility of corporate management. However, even though data security and privacy have a relationship, the concept and practice of data security is generally geared toward restricting data access. This restriction does not automatically safeguard the privacy of users. If organizational policies on the use or sale of sensitive information are not appropriate, privacy problems can still surface, even though the information and technology are secure. In many ways...

...systems — for surveillance and potential offensive action — run through thousands of pages of documents released by Edward J. Snowden, the former National Security Agency contractor. But the willingness of Adm. Michael S. Rogers to discuss purely offensive cyberweapons in his appearance before the Armed Services Committee comes at a moment when the Obama administration is reluctantly experimenting with how to discuss the subject in public, much as it gradually began to talk about drone strikes a few years ago. Admiral Rogers, who heads both the National Security Agency and its military cousin, United States Cyber Command, was answering questions about how the United States could deter attacks like the kind that struck Sony Pictures Entertainment. President Obama has said publicly that the attack originated in North Korea. When pressed, Admiral Rogers said that erecting ever-higher digital fences would never be enough, and that “we have got to broaden our capabilities to provide policy makers and operational commanders with a broader range of options. Because in the end, a purely defensive reactive strategy will be both late” and would become “incredibly resource-intense.” “So, I have been an advocate of, we also need to think about how can we increase our capacity on the offensive side here, to get to that point of deterrence.” In interviews as he...

Types of Phishing Methods Fake Website A URL similar to a legit site is purchased and then designed to look like the legit website. The hacker then sends out messages to victims, which fools them to click a link, which redirects them to the fake website. The victim them logs on, which sends the information to the hacker. Fake pop up Addition to the fake websites is the fake pop up attacks. With this attack a link is sent, but rather than sending a fake website link, the link sent is the legit site. As soon as the website loads, a pop up comes which requires the user to enter all there info to login. The info is then sent to the hacker. Fake website with validation Another addition to the fake website, this attack verifies the information with the real website. The user would enter their information into the fake website and the website would send the information to the legit website and verify the information by trying to login with the username and password, this method saves the hackers time.

...Cyber Attack University of Phoenix Martese, Daniel, Terrence and Joe May 13, 2012 Mr. Thomas A. Maricle Introduction Cyber-attack is an attempt to undermine or compromise the function of a computer-based system, or attempt to track the online movements of individuals without their permission. These types of attacks can be undetected to the user and/or network administrator. Prevention At the time of this article writing, 86% of all attacks were aimed at home users. This article is from 2006, most likely the percentage is higher now. The article states that the home user does not take control and utilize their home firewall or antivirus software. To this end, I agree because most of my users that I have helped never opened their firewall or even heard of anti-virus. The author makes note what the difference between a detection and prevention system is. Prevention systems automatically detect and block malicious network and application traffic, while allowing legitimate traffic to continue through to its destination. A detection system just detects and would rely on the prevention system to act on it. The prevention system is said to block bad malevolent code and cannot block good code at the same time, while allowing for protection of newer and more advanced types of security threats. The users should get to know what they...

...Attack Combos In the Pokémon games, there are many different strategies you could use to win against a clever foe. Some strategies can be used just to lay down an all-out assault on a foe, and some are more skilled and use a combination of defense and more adept move usage. Some Pokémon's heaviest hitting attacks rely on a combination of different moves, some more useful than others. This guide outlines some of those move combinations that you can use against an opponent. Use them on the right Pokémon, and they could be extremely dangerous. True Combos In Black & White, there are Combination Moves which are done by using two seperate moves with two of your Pokémon during Double or Triple battles. These moves will then combine and have an added extra effect. These effects vary from simple status afflictions to doing damage to the Pokémon. Only one of the Pokémon will do the damage to the Pokémon selected, but the effect will occur and lasts for several turns Grass Oath + Fire Oath | Moves Required: Grass Oath & Fire OathEffect: When you use the move Grass Oath and then the move Fire Oath during a Double or Triple battle, the move will combine and create a field of fire which causes small amounts of damage to your opponents each turn. | | Fire Oath + Water Oath | Moves Required: Fire Oath & Water OathEffect: When you use the move Fire Oath and then the move Water Oath during a Double or Triple battle, the move will combine and create a a rainbow over...

...THOMAS FORD IT255 MR. CARTER LIST PHASES OF A COMPUTER ATTACK Phase 1 - Reconnaissance Reconnaissance is probably the longest phase, sometimes lasting weeks or months. The black hat uses a variety of sources to learn as much as possible about the target business and how it operates, including * Internet searches * Social engineering * Dumpster diving * Domain name management/search services * Non-intrusive network scanning Phase 2 - Scanning Once the attacker has enough information to understand how the business works and what information of value might be available, he or she begins the process of scanning perimeter and internal network devices looking for weaknesses, including * Open ports * Open services * Vulnerable applications, including operating systems * Weak protection of data in transit * Make and model of each piece of LAN/WAN equipment Phase 3 - Gaining Access Gaining access to resources is the whole point of a modern-day attack. The usual goal is to either extract information of value to the attacker or use the network as a launch site for attacks against other targets. In either situation, the attacker must gain some level of access to one or more network devices. In addition to the defensive steps described above, security managers should make every effort to ensure end-user devices and servers are not easily accessible by unauthenticated users. This includes denying local administrator access to business users and closely monitoring...
