Backdoor Access Points

In layman's terms, a backdoor is normally a door that is obscured from the general public. It is not normally used as an active passage in the everyday working of things. In technology, the meaning is almost the same. A backdoor refers to an undisclosed point of access to a program, application, or computer system in which the standard security procedures and authentication processes are bypassed.

Computer Backdoors

This secret backdoor access is sometimes a planned installation by system developers or service providers as a remote means for diagnostics, troubleshooting, or other system tests. On the other hand, backdoor access can also be a system weakness or flaw or a malicious program, which attackers can use to exploit the system and create their own backdoor.

What is a Multipartite Virus

 A multipartite virus is a type of fast-acting malware that attacks a device's boot sector and executable files simultaneously. Multipartite viruses are often considered more problematic than traditional computer viruses due to their ability to spread in multiple ways. They are considered to be much more destructive than other viruses. Multipartite viruses infect computer systems multiple times, at varying times and in order to eradicate the virus it must be purged from the entire system. Failure to do so can result in the system being repeatedly re-infected if all parts of the virus are not eradicated.  The first reported instance of a multipartite virus was in 1989. Ghostball was the name of this particular virus and it targeted the executable files and boot sectors of the computers it infected. However, Ghostball wasn’t able to reach many victims as the internet was fairly new at the time it started spreading. Now with around half of the global population active online, mul...

What is the KLEZ virus?

 Klez is a worm that spreads via the Internet by attaching itself to mass-mailed emails using SMTP to pass itself along. The worm virus itself is a Windows PE EXE file of about 65Kb in size and is written in Microsoft Visual C++. The subject line of the email carrying the virus payload is randomly selected from a list of possible choices. The email message “From:” field will contain either one of the addresses found in a search of address books and files on the computer or an address taken from a list inside the virus body. When the virus was released, millions of email messages results and were sent around the world. This caused some messaging servers to fail and cripple internal company communications systems. Some claims were made that this virus caused billions of dollars of administrator’s and user’s time in dealing with all the errant messages, recovering failed systems and opportunities lost as a result of the failed communications. Those using GMS Anti-Virus were quickly pr...

Cryptolocker Virus Definition

 Cryptolocker is a malware threat that gained notoriety over the last years. It is a Trojan horse that infects your computer and then searches for files to encrypt. This includes anything on your hard drives and all connected media — for example, USB memory sticks or any shared network drives. In addition, the malware seeks out files and folders you store in the cloud. Only computers running a version of Windows are susceptible to Cryptolocker; the Trojan does not target Macs. Once your desktop or laptop is infected, files are "locked" using what's known as asymmetric encryption. This method relies on two "keys," one public and one private. Hackers encrypt your data using the public key, but it can only be decrypted using the unique private key they hold. The Cryptolocker virus will display warning screens indicating that your data will be destroyed if you do not pay a ransom to obtain the private key. Common Infection Methods and Risks The most common method of...
