Trojan.Win32.DNSChanger
''Trojan.Win32.DNSChanger'' is a Backdoor (computing), backdoor Trojan horse (computing), trojan that redirects users to various malicious websites through the means of altering the Domain Name Server, DNS settings of a victim's computer. The malware strain was first discovered by Microsoft, Microsoft Malware Protection Center on December 7, 2006 and later detected by McAfee Labs on April 19, 2009. Behaviour DNS changer trojans are dropped onto infected systems by other means of malicious software, such as Alureon, TDSS or Koobface. The trojan is a malicious .exe, Windows executable file that cannot spread towards other computers. Therefore, it performs several actions on behalf of the Adversary (cryptography), attacker within a compromised computer, such as changing the Domain Name Server, DNS settings in order to divert traffic to unsolicited, and potentially illegal and/or malicious domains. The Win32.DNSChanger trojan is used by organized crime syndicates to maintain click fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zlob Trojan
The Zlob Trojan, identified by some antiviruses as Trojan.Zlob, is a trojan horse (computing), Trojan horse which masquerades as a required video Fake codec, codec in the form of ActiveX. It was first detected in late 2005, but only started gaining attention in mid-2006. Once installed, it displays popup ads which appear similar to real Microsoft Windows warning popups, informing the user that their computer is infected with spyware. Clicking these popups triggers the download of a rogue software, fake anti-spyware program (such as Virus Heat and MS Antivirus (malware), MS Antivirus (Antivirus 2009)) in which the Trojan horse is hidden. The Trojan has also been linked to downloading atnvrsinstall.exe which uses the Windows Security shield icon to look as if it is an anti-virus installation file from Microsoft.

Click Fraud
Click fraud is a type of ad fraud that occurs on the Internet in pay per click (PPC) online advertising. In this type of advertising, the owners of websites that post the ads are paid based on how many site visitors click on the ads. Fraud occurs when a person, automated script, computer program or an auto clicker imitates a legitimate user of a web browser, clicking on such an ad without having an actual interest in the target of the ad's link in order to increase revenue. Click fraud is the subject of some controversy and increasing litigation due to the advertising networks being a key beneficiary of the fraud. Media entrepreneur and journalist John Battelle describes click fraud as the intentionally malicious, "decidedly black hat" practice of publishers gaming paid search advertising by employing robots or low-wage workers to click on ads on their sites repeatedly, thereby generating money to be paid by the advertiser to the publisher and to any agent the advertiser may b ...

Domain Name Server
A name server is a computer application that implements a network service for providing responses to queries against a directory service. It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request. An example of a name server is the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet. The most important function of DNS servers is the translation (resolution) of human-memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal name space of the Internet which is used to identify and locate computer systems and resources on the Internet. Domain name server The Internet maintains two principal namespaces: the domain name hierarchyRFC 1034, ''Domain Names—Concepts and Facilities'', P. Mockapetris, The Inte ...

Alureon
Alureon (also known as TDSS or TDL-4) is a trojan and rootkit created to steal data by intercepting a system's network traffic and searching for banking usernames and passwords, credit card data, PayPal information, social security numbers, and other sensitive user data. Following a series of customer complaints, Microsoft determined that Alureon caused a wave of BSoDs on some 32-bit Microsoft Windows systems. The update, MS10-015, triggered these crashes by breaking assumptions made by the malware author(s). According to research conducted by Microsoft, Alureon was the second most active botnet in the second quarter of 2010. Description The Alureon bootkit was first identified around 2007. Personal computers are usually infected when users manually download and install Trojan software. Alureon is known to have been bundled with the rogue security software, "Security Essentials 2010". When the dropper is executed, it first hijacks the print spooler service (spoolsv.exe) to updat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Backdoor (computing)
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer"—a tiny computer-within-a-computer such as that found in Intel's AMT technology). Backdoors are most often used for securing remote access to a computer, or obtaining access to plaintext in cryptosystems. From there it may be used to gain access to privileged information like passwords, corrupt or delete data on hard drives, or transfer information within autoschediastic networks. In the United States, the 1994 Communications Assistance for Law Enforcement Act forces internet providers to provide backdoors for government authorities. In 2024, the U.S. government realized that China had been tapping communications in the U.S. using that infrastructure for months, or perhaps longer; China recorded presidential candidate campaign offi ...
