How does a logic bomb work?
A Logic Bomb is a piece of often-malicious code that is intentionally inserted into software. This makes their presence undetected until it executes their function, which can range from inflicting harm through files deletion to self-propagation to the unusual, in the case of a 2019 attack by a software vendor.
What is logic bomb explain with example?
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.
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.
Is logic bomb a virus?
Is a logic bomb malware? Logic bombs are small bits of code contained in other programs. Although they might be malicious, they’re not technically malware — it’s a fine line. Common types of malware include viruses and worms, which can contain logic bombs as part of their attack strategy.
Is a backdoor virus?
A backdoor virus, therefore, is a malicious code, which by exploiting system flaws and vulnerabilities, is used to facilitate remote unauthorized access to a computer system or program.
What events can trigger a logic bomb?
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 rootkit virus?
A rootkit is a type of malware designed to give hackers access to and control over a target device. Although most rootkits affect the software and the operating system, some can also infect your computer’s hardware and firmware.
Why is it difficult to prevent a logic bomb?
Logic bombs are hard to prevent due to the reason that they can be deployed from anywhere. By limiting employee access to specific files and folders, a potential attacker will be exposed to carry out the logic bomb deployment and this may prevent the subject to carry out the attack.
What is backdoor with example?
In either case, they can potentially represent an information security vulnerability. The following are common examples of a backdoor….APIs, Services & Components.

What is the most common backdoor?
1. ShadowPad. Back in 2017, security researchers discovered an advanced backdoor integrated into the server management applications of South Korea- and U.S.-based NetSarang. Dubbed ShadowPad, the backdoor has the ability to download and install additional malware as well as spoof data.
What are two rootkit types?
Here are five types of rootkits.
- Hardware or firmware rootkit. The name of this type of rootkit comes from where it is installed on your computer.
- Bootloader rootkit. Your computer’s bootloader is an important tool.
- Memory rootkit.
- Application rootkit.
- Kernel mode rootkits.
What does a high level of lipoprotein ( a ) mean?
Low-density lipoprotein (LDL), or “bad” cholesterol. Lipoprotein (a) is a type of LDL (bad) cholesterol. A high level of lipoprotein (a) may mean you are at risk for heart disease. Other names: cholesterol Lp (a), Lp (a)
Why are LDL particles known as bad lipoproteins?
Low-density lipoproteins (LDL) carry 3,000 to 6,000 fat molecules (phospholipids, cholesterol, triglycerides, etc.) around the body. LDL particles are sometimes referred to as “bad” lipoprotein because concentrations, dose related, correlate with atherosclerosis progression.
What is the density of an intermediate density lipoprotein?
Intermediate Density Lipoproteins (IDL) The density of IDL is between 1.006 and 1.019 g/mL and ranges in diameter from 25 to 50 nm. In a healthy individual, it is composed of approximately 31% triacylglycerol, 22% phospholipid, and 18% protein. This type of lipoprotein is not usually present in the blood when fasting.
What’s the density of a lipoprotein during fasting?
This type of lipoprotein is not usually present in the blood when fasting. VLDL has a density between 0.950 and 1.006 g/mL and ranges in diameter from 30 to 80 nm.
