Scareware is a form of malware which uses social engineering to cause shock, anxiety, or the perception of a threat in order to manipulate users into buying unwanted software. Scareware is part of a class of malicious software that includes rogue security software, ransomware and other scam software that tricks users into believing their computer is infected with a virus, then suggests that they download and pay for fake antivirus software to remove it. Usually the virus is fictional and the software is non-functional or malware itself. According to the Anti-Phishing Working Group, the number of scareware packages in circulation rose from 2,850 to 9,287 in the second half of 2008. In the first half of 2009, the APWG identified a 585% increase in scareware programs.
Norton AntiVirus is an anti-virus or anti-malware software product founded by Peter Norton, developed and distributed by Symantec since 1990 as part of its Norton family of computer security products. It uses signatures and heuristics to identify viruses. Other features included in it are e-mail spam filtering and phishing protection.
Graybird is a Trojan horse that hides its presence on compromised computers and downloads files from remote Web sites. There are many variations of this virus.
Mobile malware is malicious software that targets mobile phones or wireless-enabled Personal digital assistants (PDA), by causing the collapse of the system and loss or leakage of confidential information. As wireless phones and PDA networks have become more and more common and have grown in complexity, it has become increasingly difficult to ensure their safety and security against electronic attacks in the form of viruses or other malware.
WinFixer was a family of scareware rogue security programs developed by Winsoftware which claimed to repair computer system problems on Microsoft Windows computers if a user purchased the full version of the software. The software was mainly installed without the user's consent. McAfee claimed that "the primary function of the free version appears to be to alarm the user into paying for registration, at least partially based on false or erroneous detections." The program prompted the user to purchase a paid copy of the program.
The Vundo Trojan is either a Trojan horse or a computer worm that is known to cause popups and advertising for rogue antispyware programs, and sporadically other misbehavior including performance degradation and denial of service with some websites including Google and Facebook. It also is used to deliver other malware to its host computers. Later versions include rootkits and ransomware.
Trojan.Emcodec.E is a trojan horse that is mis-represented as an audio and video codec for Windows-based PCs. It exists in various variants with names such as Media Codec, Ecodec, Imediacodec, IntCodec, Pcodec, SVideocodec, Video iCodec, QualityCodec, Vcodec, Zip Codec, zCodec, ZCODEC and began to be widely used in spring 2005.
Rogue security software is a form of malicious software and internet fraud that misleads users into believing there is a virus on their computer and aims to convince them to pay for a fake malware removal tool that actually installs malware on their computer. It is a form of scareware that manipulates users through fear, and a form of ransomware. Rogue security software has been a serious security threat in desktop computing since 2008. An early example that gained infamy was SpySheriff and its clones, such as Nava Shield.
SpySheriff is malware that disguises itself as anti-spyware software. It attempts to mislead the user with false security alerts, threatening them into buying the program. Like other rogue antiviruses, after producing a list of false threats, it prompts the user to pay to remove them. The software is particularly difficult to remove, since it nests its components in System Restore folders, and also blocks some system management tools. However, SpySheriff can be removed by an experienced user, antivirus software, or by using a rescue disk.
The Storm Worm is a phishing backdoor Trojan horse that affects computers using Microsoft operating systems, discovered on January 17, 2007. The worm is also known as:
Koobface is a network worm that attacks Microsoft Windows, Mac OS X, and Linux platforms. This worm originally targeted users of networking websites such as Facebook, Skype, Yahoo Messenger, and email websites such as GMail, Yahoo Mail, and AOL Mail. It also targets other networking websites, such as MySpace, Twitter, and it can infect other devices on the same local network. Technical support scammers also fraudulently claim to their intended victims that they have a Koobface infection on their computer by using fake popups and using built-in Windows programs.
Gumblar is a malicious JavaScript trojan horse file that redirects a user's Google searches, and then installs rogue security software. Also known as Troj/JSRedir-R this botnet first appeared in 2009.
Daprosy worm was a malicious computer program that spreads via local area network (LAN) connections, spammed e-mails and USB mass storage devices. Infection comes from a single read1st.exe file where several dozen clones are created at once bearing the names of compromised folders. The most obvious symptom of Daprosy infection is the presence of Classified.exe or Do not open - secrets!.exe files from infected folders.
The RSPlug Trojan horse, a form of DNSChanger, is malware targeting the Mac OS X operating system. The first incarnation of the trojan, OSX.RSPlug.A, was discovered on October 30, 2007 by Mac security researchers at Intego.
MS Antivirus is a scareware rogue anti-virus which purports to remove virus infections found on a computer running Microsoft Windows. It attempts to scam the user into purchasing a "full version" of the software. The company and the individuals behind Bakasoftware operated under other different 'company' names, including Innovagest2000, Innovative Marketing Ukraine, Pandora Software, LocusSoftware, etc.
DNSChanger is a DNS hijacking Trojan. The work of an Estonian company known as Rove Digital, the malware infected computers by modifying a computer's DNS entries to point toward its own rogue name servers, which then injected its own advertising into Web pages. At its peak, DNSChanger was estimated to have infected over four million computers, bringing in at least US$14 million in profits to its operator from fraudulent advertising revenue.
Sality is the classification for a family of malicious software (malware), which infects Microsoft Windows systems files. Sality was first discovered in 2003 and has advanced to become a dynamic, enduring and full-featured form of malicious code. Systems infected with Sality may communicate over a peer-to-peer (P2P) network to form a botnet to relay spam, proxying of communications, exfiltrating sensitive data, compromising web servers and/or coordinating distributed computing tasks to process intensive tasks. Since 2010, certain variants of Sality have also incorporated rootkit functions as part of an ongoing evolution of the malware family. Because of its continued development and capabilities, Sality is considered one of the most complex and formidable forms of malware to date.
Slenfbot is the classification for a family of malicious software (malware), which infects files on Microsoft Windows systems. Slenfbot was first discovered in 2007 and, since then, numerous variants have followed; each with slightly different characteristics and new additions to the worm's payload, such as the ability to provide the attacker with unauthorized access to the compromised host. Slenfbot primarily spreads by luring users to follow links to websites, which contain a malicious payload. Slenfbot propagates via instant messaging applications, removable drives and/or the local network via network shares. The code for Slenfbot appears to be closely managed, which may provide attribution to a single group and/or indicate that a large portion of the code is shared amongst multiple groups. The inclusion of other malware families and variants as well as its own continuous evolution, makes Slenfbot a highly effective downloader with a propensity to cause even more damage to compromised systems.
Trojan.Win32.DNSChanger is a backdoor trojan that redirects users to various malicious websites through the means of altering the DNS settings of a victim's computer. The malware strain was first discovered by Microsoft Malware Protection Center on December 7, 2006 and later detected by McAfee Labs on April 19, 2009.
