CREEPER VIRUS

[Audio] CREEPER VIRUS Group 1 presentation. CREEPER VIRUS.

[Audio] What is a computer virus? A computer virus is a type of malware that attaches itself to other programs, self-replicates, and spreads from one computer to another. When a virus infects a computer, it makes copies of itself and attaches to other files or documents. It then modifies those files and continues to spread. Viruses infect computers discreetly, and they're often designed to destroy personal files or gain control of devices. Making copies of themselves, computer viruses spread across devices and networks like biological viruses passing from one person to the next. And just like the biological versions, some computer viruses are simply annoying while others can cause major damage..

[Audio] How do computer viruses work? Dormant phase: This is when the virus is hidden on your system, lying in wait. Propagation phase: This is the viral stage, when the virus begins to self-replicate, stashing copies of itself in files, programs, or other parts of your disk. The clones may be slightly altered in an attempt to avoid detection, and these copies will also self-replicate, creating more clones that continue to copy and spread. Triggering phase: A specific action is generally required to trigger or activate the virus. This could be a user action, like clicking an icon or opening an app. Other viruses are programmed to come to life after a certain amount of time, such as a logic bomb designed to trigger after your computer has rebooted a certain number of times (this is done to obfuscate the origin of the virus). execution phase: Now the virus's program is executed and releases its payload, the malicious code that harms your device..

[Audio] What is the Creeper Virus? The Creeper virus is the first computer virus ever developed. Bob Thomas created it in 1971 as an experimental self-duplication program. His idea, however, was not to cause harm and damage but merely illustrate how a mobile application works. Without planning to, the Creeper virus corrupted Digital Equipment Corporation's PDP-10 mainframe computers operating on the TEN-Extended (TENEX) operating system (OS). It messed up connected teletype computer screens, causing them to display the message, "I'm the creeper, catch me if you can!". While the Creeper virus did corrupt systems, it is not considered a piece of malware like most of today's computer viruses. The only damage it did was to display a message, nothing more. It did not destroy or steal data, demand a ransom, or render the actual mainframe inoperable..

[Audio] 6 Facts About the Creeper Computer Virus: The First Computer Virus: Creeper was the world's first computer virus. It emerged in the early 1970s. Didn't Cause Harm: Computers infected by Creeper didn't succumb to data loss or other malicious acts. Targeted the TENEX OS: TENEX was commonly used by businesses back then, though it was later replaced with the TOPS-20 OS. Displayed a Message: It may not have caused harm to infected computers and devices, but Creeper still displayed a message. Raised Awareness for Cybersecurity: Creeper played an important role in raising awareness for cybersecurity. Creeper vs Reaper: addition to Creeper, there's Reaper. Reaper wasn't a type of virus or malware. Rather, it was a type of antivirus software..

[Audio] The Creeper Program. As noted by Discovery, the Creeper program, often regarded as the first virus, was created in 1971 by Bob Thomas of BBN. Creeper was actually designed as a security test to see if a self-replicating program was possible. It was—sort of. With each new hard drive infected, Creeper would try to remove itself from the previous host. Creeper had no malicious intent and only displayed a simple message: "I'M THE CREEPER. CATCH ME IF YOU CAN!".

[Audio] Destruction caused by Creeper virus One of the first known examples of malware was the Creeper virus in 1971, which was created as an experiment by BBN Technologies engineer Robert Thomas. Creeper was designed to infect mainframes on ARPANET. While the program did not alter functions or steal or delete data, it moved from one mainframe to another without permission while displaying a teletype message that read, "I'm the creeper: Catch me if you can." Creeper was later altered by computer scientist Ray Tomlinson, who added the ability to self-replicate to the virus and created the first known computer worm..

[Audio] How was creeper virus stopped? Reaper was the first anti-virus software, designed to delete Creeper by moving across the ARPANET. It was created by Ray Tomlinson in 1972. This led not only to the practical confirmation of the ideas already enunciated by John von Neumann in the 1940s, but also to the creation of his nemesis, the first anti-virus in history: Reaper. Reaper was clearly an answer to Creeper. Just pay attention to its name; while Creeper means "creeper", Reaper means "pruner". Now it all makes sense..
