Computer Forensics PORTAL

Hacking

This is a type of crime wherein a person’s computer is broken into so that his personal or sensitive information can be accessed. In the United States, hacking is classified as a felony and punishable as such. This is different from ethical hacking, which many organizations use to check their Internet security protection. In hacking, the criminal uses a variety of software to enter a person’s computer and the person may not be aware that his computer is being accessed from a remote location.

 

Theft

This crime occurs when a person violates copyrights and downloads music, movies, games and software. There are even peer sharing websites which encourage software piracy and many of these websites are now being targeted by the FBI. Today, the justice system is addressing this cyber crime and there are laws that prevent people from illegal downloading.

 

Cyber Stalking

This is a kind of online harassment wherein the victim is subjected to a barrage of online messages and emails. Typically, these stalkers know their victims and instead of resorting to offline stalking, they use the Internet to stalk. However, if they notice that cyber stalking is not having the desired effect, they begin offline stalking along with cyber stalking to make the victims’ lives more miserable.

 

Identity Theft

This has become a major problem with people using the Internet for cash transactions and banking services. In this cyber crime, a criminal accesses data about a person’s bank account, credit cards, Social Security, debit card and other sensitive information to siphon money or to buy things online in the victim’s name. It can result in major financial losses for the victim and even spoil the victim’s credit history.

 

Malicious Software

These are Internet-based software or programs that are used to disrupt a network. The software is used to gain access to a system to steal sensitive information or data or causing damage to software present in the system.

Child soliciting and Abuse: This is also a type of cyber crime wherein criminals solicit minors via chat rooms for the purpose of child pornography. The FBI has been spending a lot of time monitoring chat rooms frequented by children with the hopes of reducing and preventing child abuse and soliciting.

 

Ransomware

This is one of the detestable malware-based attacks. Ransomware enters your computer network and encrypts your files using public-key encryption, and unlike other malware this encryption key remains on the hacker’s server. Attacked users are then asked to pay huge ransoms to receive this private key.

 

DDoS attacks

DDoS attacks are used to make an online service unavailable and bring it down, by bombarding or overwhelming it with traffic from multiple locations and sources. Large networks of infected computers, called Botnets are developed by planting malware on the victim computers. The idea is normally to draw attention to the DDOS attack, and allow the hacker to hack into a system. Extortion and blackmail could be the other motivations.

 

Botnets

Botnets are networks of compromised computers, controlled by remote attackers in order to perform such illicit tasks as sending spam or attacking other computers.  Computer Bots can also be used act like malware and carry out malicious tasks. Then can be used to assemble a network of computers and then compromise them.

 

Malvertising

Malvertising is a method whereby users download malicious code by simply clicking at some advertisement on any website that is infected. In most cases, the websites are innocent. It is the cyber criminals who insert malicious advertisements on the websites without the knowledge of the latter. It is the work of advert companies to check out if an advertisement is malicious but given the number of advertisements they have to deal with, the malverts easily pass off as genuine ads.

In other cases, the cyber criminals show clean ads for a period of time and then replace it with malverts so that the websites and advertisements do not suspect. They display the malverts for a while and remove it from the site after meeting their targets. All this is so fast that the website does not even know they were used as a tool for cybercrime. Malvertising is one of the fastest, increasing types of cybercrime.

 

Drive-By-Downloads

Drive By Downloads too, come close to malvertising. You visit a website and it triggers a download of malicious code to your computer. These computers are then used to aggregate data and to manipulate other computers as well.

The websites may or may not know that they have been compromised. Mostly, the cyber criminals use vulnerable software such as Java and Adobe Flash and Microsoft Silverlight to inject malicious codes as soon as a browser visits the infected website. The user does not even know that there is a download in progress.

 

Remote Administration Tools

Remote Administration Tools are used to carry out illegal activities. It can be used to control the computer using shell commands, steal files/data, send location of the computer to a remote controlling device and more.

Read this post to learn more about how you can prevent the illegal use of RATs or Remote Administration Tools.

 

Exploit Kits

A vulnerability means some problem in the coding of a software that enables cyber criminals to gain control of your computer. There are ready to use tools (exploit kits) in the Internet market which people can buy and use it against you. These exploit kits are upgraded just like normal software. Only difference is these are illegal. They are available mostly in hacking forums as well as on the Darknet.
