You may have heard a lot lately about what is a malware attack. Well, you must be wondering what cyber criminals are, right? Malware is short for malicious software. It’s a particular computer program which is purposely created with malicious intent to wreak havoc on a computer system, software, server, network, or client. The primary purpose in carrying out such an attack is to gain unauthorized access to personal or even sensitive data of internet users or to destroy their electronic devices for monetary benefit.
Recently, cyber criminals have been focusing on security systems, particularly those that are connected to the web and operate off local area networks (LANs). With these LANs, an unsecured network is vulnerable to attack from the internet, as it can simply be too easy for an intruder to get in. This means that the potential for a malware attack has become greater than ever before. And one such possible method involves compromising USB drives.
USB malware attacks
So, what is a USB malware attack? Simply put, it is when cyber criminals use a USB pen drive or other USB device to send an infected program or active exploit code to remote servers in order to gain access to data or simply to execute malicious code on the system. In most cases, the programmers behind such attacks utilize coding that is highly advanced and difficult to defend against. That is why most leading security firms and malware experts advise PC users to never plug in USB pens or other USB devices to their computers and to never share them with friends or family members.
One notable instance that demonstrates the kind of cyber attack that can happen through a USB device took place last week, when a major US insurance company sent a warning to its customers about what it called “malware” being distributed via “joke” emails. The joke was that the emails were from legitimate insurance companies, and that anyone who clicked on the links would be offered a free insurance policy. What the joke really told was that thousands of people had their personal details stolen by one or more malicious Internet hackers.
This is just one of the examples that demonstrate the ways that malware attacks can spread quickly through the network. Another common example is spyware, which uses the network to send information back to attackers. Malicious software can also find ways to directly install itself on a computer. All of these different forms of malware attacks are considered malicious software, because they try to gain access to sensitive data that should only be within the reach of licensed users.
In fact, many people who download pirated software programs often encounter a malware attack afterwards. This is because the pirated program was installed without the knowledge or consent of the user. The cybercriminals may gain access to financial gain as well as other important functions. Some programs make it possible for them to gain access to credit card numbers, confidential customer lists, and other types of data.
Worms and vulnerabilities
Some hackers use what is known as “worms” or “vulnerability vulnerabilities” in order to gain access to computers that are not protected. A worm can be programmed to do just about anything. It could open a back door to a system, exposing valuable information and causing a host of problems. A vulnerability is a way for an attacker or cyber-intruder to gain access if they are able to compromise a system. Often, the two attacks occur at the same time, causing significant damage.
What is a malware attack? This is the question that many people ask, so it is helpful to know what these attacks look like. A Trojan horse virus may have a single application that contains a single link that releasing a payload. Other Trojans have more complex code that requires several files to be uploaded before complete. Other malicious applications that can be used in attacks do not require any program download, but instead rely on Trojans to exploit a vulnerable computer. By using malware to gain access to computers, a cyber-intruder gains a foothold into a system and can wreak havoc.
