What is a logic time bomb?

How is a logic bomb triggered?
A logic bomb is a malicious program that is triggered when a logical condition is met, such as after a number of transactions have been processed, or on a specific date (also called a time bomb). Malware such as worms often contain logic bombs, behaving in one manner, then changing tactics on a specific date and time.
What is the difference between virus and logic bomb?
Unlike viruses and worms, which can infect a system on their own, a logic bomb is often inserted by someone with inside knowledge of the system — such as when a disgruntled employee embeds a logic bomb in their company’s network.
Are logic bombs illegal?
From 1980 to 1985, some software developers imbedded logic bomb into their software, set to destroy the software itself if the license was not renewed. Of course, today this practice is illegal, but people are still using logic bombs in other contexts to achieve their ends.

What is time bomb code?
A time bomb is a malicious piece of code that activates at a specific date and time or after a certain amount of time has elapsed.

What is another name for a logic bomb?
Another name for a logic bomb is slag code, which refers to the manipulated code that makes an otherwise safe program harmful. Time bombs are a popular type of logic bomb, and sometimes the two terms are used interchangeably. Logic bombs are also sometimes called code bombs or cyber bombs.
Why logic bomb is used?
A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
What does Alabama virus do?
Instead of searching for a file to infect, Alabama searches for a file to cross-reference. The virus modifies the FAT entry so that when the user executes one file, another will appear. For instance, on a machine where Alabama is resident, executing PROGRAM1.
Is a Trojan malware?
A Trojan Horse Virus is a type of malware that downloads onto a computer disguised as a legitimate program. The delivery method typically sees an attacker use social engineering to hide malicious code within legitimate software to try and gain users’ system access with their software.
What is backdoor virus?
A backdoor is a malicious computer program used to provide the attacker with unauthorized remote access to a compromised PC by exploiting security vulnerabilities. This backdoor virus works in the background and hides from the user. It is quite difficult to detect as it is very similar to other malware viruses.
What is logic bomb explain with example?
What is Christmas virus?
What is sleeper virus?
Like a trojan horse, sleeper malware lies in wait on the device it has infected, timed to go off either on a specific date, or at the end of its countdown. Then when the time comes, it’s too late to identify where the threat has come from and too late to stop it.
Who created Trojan virus?
programmer John Walker
Called ANIMAL, the first Trojan (although there is some debate as to whether this was a Trojan, or simply another virus) was developed by computer programmer John Walker in 1975, according to Fourmilab.
Does factory reset remove Trojans?
In short, yes, a factory reset will usually remove viruses … but (there’s always a ‘but’ isn’t there?) not always. Due to the wide variety and ever-evolving nature of computer viruses, it’s impossible to say for sure that a factory reset will be the answer to curing your device from malware infection.
Why do hackers use backdoors?
Backdoors enable hackers to gain command and control (C&C) of the targeted network without being detected and may use legitimate websites or services to launch an attack. An example of this is to use a web blog URL to decipher the ciphertext and locate any IP addresses of the C&C server list.
Can backdoors be removed?
Removing a backdoor from the system
You can hardly find or remove a backdoor manually. That’s why we highly recommend using the automatic removal option. Many security programs are offered for backdoors removal, although some viruses might require scans using a few different anti-malware tools.
What are the 7 types of virus?
KEYLOGGERS. Keyloggers are surprisingly simple, and can be implemented in many different ways.
What is the first virus?
the tobacco mosaic virus
Research on viruses has been recognized with several Nobel Prizes. Viruses attack both animals and plants. Tobacco plants are damaged sometimes with mosaic-like patterns on the leaves. These patterns are caused by the tobacco mosaic virus, which at the end of the 19th century became the first virus ever discovered.
How old are viruses on earth?
They existed 3.5 billion years before humans evolved on Earth. They’re neither dead nor alive. Their genetic material is embedded in our own DNA, constituting close to 10% of the human genome. They can attack most forms of life on our planet, from bacteria to plants to animals.
Will a factory reset stop a hacker?
The majority of malware can be removed with a factory reset of your phone. This will, however, wipe any data stored on your device, such as photos, notes, and contacts, so it’s important to back up this data before resetting your device.
