Nimda
The Nimda virus is a malicious file-infecting computer worm. It quickly spread, surpassing the economic damage caused by previous outbreaks such as Code Red (computer worm), Code Red. The first released advisory about this thread (worm) was released on September 18, 2001. Due to the release date, exactly one week after the September 11 attacks, attacks on the World Trade Center and Pentagon, some media quickly began speculating a link between the virus and Al Qaeda, though this theory ended up proving unfounded. Nimda affected both user workstations (Client (computing), clients) running Windows 95, Windows 98, 98, Windows NT 4.0, NT, Windows 2000, 2000, or Windows XP, XP and Server (computing), servers running Windows NT and 2000. The worm's name comes from the reversed spelling of "System administrator, admin". F-Secure found the text "Concept Virus(CV) V.5, Copyright(C)2001 R.P.China" in the Nimda code, suggesting its country of origin. However, they also noted that a computer ...

Computer Worm
A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. It will use this machine as a host to scan and infect other computers. When these new worm-invaded computers are controlled, the worm will continue to scan and infect other computers using these computers as hosts, and this behaviour will continue. Computer worms use recursive methods to copy themselves without host programs and distribute themselves based on the law of exponential growth, thus controlling and infecting more and more computers in a short time. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer. Many worms are designed only to spread, and do not attempt to change the systems they pass through. However, as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Code Red (computer Worm)
Code Red was a computer worm observed on the Internet on July 15, 2001. It attacked computers running Microsoft's IIS web server. It was the first large scale, mixed threat attack to successfully target enterprise networks. The Code Red worm was first discovered and researched by eEye Digital Security employees Marc Maiffret and Ryan Permeh when it exploited a vulnerability discovered by Riley Hassell. They named it "Code Red" because Mountain Dew Code Red was what they were drinking at the time. Although the worm had been released on July 13, the largest group of infected computers was seen on July 19, 2001. On that day, the number of infected hosts reached 359,000. It spread worldwide but was particularly prevalent in North America, Europe and Asia (including China and India). Concept Exploited vulnerability The worm showed a vulnerability in the growing software distributed with IIS, described in Microsoft Security Bulletin MS01-033, for which a patch had been available a ...

Mixed Threat Attack
Regarding computer security, a mixed threat attack is an attack that uses several different tactics to infiltrate a computer user's environment. A mixed threat attack might include an infected file that comes in by way of spam or can be received by an Internet download. Mixed threat attacks try to exploit multiple vulnerabilities to get into a system. By launching multiple diverse attacks in parallel, the attacker can exploit more entry points than with just a single attack. Because these threats are based on multiple single-attacks, they are much harder to detect. Firewalls can help with these types of attacks; if configured correctly, they are somewhat effective against this type of attack. However, if the attack is embedded inside an application, it is no longer able to prevent it. Typical techniques employed are to define the multiple access threat with a signature that can represent identification for the virus removal software. These types of techniques need to be employ ...

Timeline Of Notable Computer Viruses And Worms
A timeline is a display of a list of events in chronological order. It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. This timescale is dependent on the events in the timeline. A timeline of evolution can be over millions of years, whereas a timeline for the day of the September 11 attacks can take place over minutes, and that of an explosion over milliseconds. While many timelines use a linear timescale—especially where very large or small timespans are relevant -- logarithmic timelines entail a logarithmic scale of time; some "hurry up and wait" chronologies are depicted with zoom lens metaphors. History Time and space, particularly the line, are intertwined concepts in human thought. The line is ubiquitous in clocks in the f ...

Internet Information Services
Internet Information Services (IIS-pronounced 2S, formerly Internet Information Server) is an extensible web server software created by Microsoft for use with the Windows NT family. IIS supports HTTP, HTTP/2, HTTPS, FTP, FTPS, SMTP and NNTP. It has been an integral part of the Windows NT family since Windows NT 4.0, though it may be absent from some editions (e.g. Windows XP Home edition), and is not active by default. History The first Microsoft web server was a research project at the European Microsoft Windows NT Academic Centre (EMWAC), part of the University of Edinburgh in Scotland, and was distributed as freeware. However, since the EMWAC server was unable to handle the volume of traffic going to Microsoft.com, Microsoft was forced to develop its own web server, IIS. Almost every version of IIS was released either alongside or with a version of Microsoft Windows: * IIS 1.0 was initially released as a free add-on for Windows NT 3.51. * IIS 2.0 was included with Windo ...

Exploit (computer Security)
An exploit (from the English verb ''to exploit'', meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service (DoS or related DDoS) attack. In lay terms, some exploit is akin to a 'hack'. Classification There are several methods of classifying exploits. The most common is by how the exploit communicates to the vulnerable software. A ''remote exploit'' works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A ''local exploit'' requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past tho ...
