Nt1310 Unit 3 Exercise 1

A frequent tactics used by criminals involves convincing users that a virus has infected their computer, than suggesting that they download (and pay for) fake antivirus software to remove it. Usually the virus is entirely fictional and the software is non fictional or Malware

They will want to plug any security holes, continue to patch the systems, and research new exploits. Metasploit’s exploit modules allow for privilege escalation (obtaining root or admin access) and SMB related attacks. For example, when testing client-side exploits at the Police Department, the exploits may fail due to their having limited user rights, requiring a tweak to the exploit module or payload. Another key feature of Metasploit is its meterpreter script, ‘getsystem‘, that will use a number of different techniques to attempt to gain SYSTEM level privileges on the target. This will assist the Police Department in closing privilege escalation attacks, which appear to have occurred in the

People often use the same username and password for many different systems, so these stolen credentials may be used to access other systems not yet infected. Once access is gained, additional information theft or malware installation can take place. Another way spyware puts systems at future risk is by installing backdoor access mechanisms. These backdoors give the malware operator access to control the system or to command the system to download and run arbitrary applications. Attackers can build vast collections of compromised systems without originally compromising a single

One false move can bring about reaching malware or having touchy information spilled. The Newstarads.com distributed to clients ' machine through misleading systems. The fundamental spread vector is bundling. The shady instrument hitches a ride with pirated applications, shareware & freeware which mediate the installation. The host is alluded to as a download customer.

Viruses tend to implant itself into a computer. Worse that it does is to steal credit card inputs, passwords and personal information. Hackers can than access these information and use it. Malicious software that hooks into the victim’s browser, and records all data submitted into Web site forms, including credit card information. Leads to authorize online charges.

Once you pay them they can demand even more and threaten you by sending lower degree virus as your files and system is under GPAA Ransomware control. How to remove GPAA ransomware from PC? Removing is the only way you can get rid of GPAA ransomware completely. We have provided some manual steps through which you can easily remove this computer virus from your PC. We concern your safety so we suggest you to get an anti-malware program that regularly scans your PC and remove such harmful virus automatically and keep your PC clean and also prevent you from future threats.

While researching on Windows and UNIX, I found that UNIX has better built-in security and permissions features than Windows (Haas, n.d). While upgrading software from Microsoft, it often requires the user to purchase new or more hardware or prerequisite software, but UNIX on the other hand does not require purchasing (Haas, n.d). UNIX operating system is more stable, faster and more secure compare to windows because most software is written to create damage to windows (Noyes, 2010). In windows if you leave a port open it can be easily used by hacker to introduce a virus in your computer whereas UNIX has to go through various executable permissions that why UNIX is considered more secure than Windows (Noyes, 2010). While windows users are more than UNIX users worldwide, the potential of windows facing security challenge is higher as hacker’s attempts to break the security and viruses built to break in.

Many forms of spyware, however, are more malicious and can have serious effects on users and businesses. Key logging spyware, for example, transmits to the author of the spyware a log of every keystroke entered on that computer. The author can then sift through this data to find valuable information, such as credit card numbers, security codes and confidential information, from that user or their business. Other types of spyware search through the data stored on the host computer for particular types of file, which are likely to contain confidential or personal information, such as Word documents or images, and transmit them to the spyware

Based on the type of attack, the further action depends. As the rate of computer crimes increases there is a need for a well defined set of Computer Forensic Methodologies.These methods help in solving such computer crimes.The evidences that are seized from the computer devices are likely to change,can be altered easily,so they are to be handled properly using methodologies.These methodologies can vary based on the adopted procedures in companies. The examiner involves in recovering hidden, deleted and temporary files.They helps in the examination of servers,workstations, standalone computers and other storage medias and procedure involved in the process can be difficult or easier based on the media that is to be analyzed.During the process of evidence examination,the logs are to be maintained which play a crucial role in

In this modern world the need for designing and developing an application with good secure features is very high. I have also learned what an error exceptional handling is and why is it important in code review. I have also learned that in developing a software product or in the software development life cycle process, a software product must be teste in earlier stages and very frequently. This recalled my knowledge of secure software development life cycle. One must know the importance of secure software development life cycle.

Write privilege that allows a user to change something Execute privilege is that allows a user to create folders, files or set date. Software updating If you want to protect your computer from any malicious activities, therefore, you should update your computer security software regularly. It is very important to update a software security software because some weakness software may allow a hacker or viruses to gain access to your computer. Moreover, update a software can able to make your computer faster. If you do not update the security software that means there will be changes to get attacks by hackers and viruses so you should update a security software regularly.

Lowry Williams IS 4670 Cybercrime Forensics Unit 5 Assignment 1 Create data recovery plan Data the count may order or give you authorize to seizure a computer so that you may be able to extracted things from the computer’s hard drives. You need to do it in many difference phases you want to insure that the integrity of the computer evidence. You should copies all the files onto a write once only CD- read only memory disks. You may want to “ clone” your computer hard drive, you would do this, because you would not want to mess up the hard drive that was on your computer. This also means that you would be copying everything this will including the operating software.

If the request is valid then it is further checked for other attacks, otherwise it is blocked and stored in the log with the attack type that is found in that request. In HTTP request smuggling attack, a malicious request contains multiple start lines that are not allowed in one HTTP request (violation of RFC 2616). When the hacker tries to assign multiple start lines to one request, it will be detected by the system analyzer and reported as an HTTP request smuggling attack. A buffer overflow is the computing equivalent of trying to pour two liters of water into a one-liter pitcher, some water is going to spill out and make a mess. A buffer (or array or string) is a space in which data can be held.

1. Viruses Can destroy all of the data and erase all of the file or misused by the attacker. Have the anti-virus downloaded in your computer and make sure your computer is completely updated. 2. Phishing Attacker will be able to get the private information of the person and will gain access on computer Be able to recognize the fake emails from the attacker and avoid opening them up.
