PureVPN UpdatesWhat is a Logic Bomb & How to Prevent it?

Ticking time bombs are something only seen in action movies, right? Well, not anymore. In the computing world, some bombs exist with the sole purpose of disrupting your device and causing severe harm. This bomb is known as a logic bomb.

The downside of a logic bomb is that you’re unaware when the bomb might explode. Let’s understand what a logic bomb is and how the malicious program impacts your online security.

What is a Logic Bomb?

A logic bomb is a series of malicious code used to cause damage to a device or network when a specific programmed condition is met. The term means that a bomb “explodes” when a specific programmed condition triggers it.

A logic bomb attack could alter the devices’ date or time, delete a particular record from the system and even launch an infected software application that can cripple your device. The damage caused by a logic bomb attack can vary significantly from device to device and can cause data corruption, file deletion, and even hard drive clearing.

The Possibility of a Logic Bomb

You can consider a logic bomb to be a type of malware. However, unlike other forms of malware, a logic bomb attack tends to originate from an individual working within the same organization where the attack took place. That individual might have access to sensitive data needed to carry out the attack.

A logic bomb can be a typical way of taking revenge on a company that might fire an employee. That employee might be savvy enough to create a logic bomb that they diffuse each day, and that they alone are the only ones capable of executing. Once the employee is fired, the attack could launch as programmed by the ex-employee.

How Does a Logic Bomb Work

A logic bomb attack is covertly injected into a device via the use of a malicious code. The malicious code stays silent within the device or network and is usually unnoticeable until the programmed trigger begins.

There are two types of triggers when it comes to logic bomb attacks – positive or negative. A logic bomb with a positive trigger occurs once the specified condition is met, such as the date or time that arrives for the attack to launch.

On the other hand, a negative trigger begins when the condition is not met, such as an employee being unable to diffuse the malicious code by a particular time. In either state, the logic bomb will begin and start causing havoc.

How to Prevent Logic Bombs

Logic bombs are evil, malicious code that can be hard to detect. Simultaneously, you can take a few preventive measures to steer clear of logic bomb attacks.

Use a reputable antivirus and keep it updated

A robust antivirus can quickly scan and detect viruses and other malicious code that are hiding malicious code for a logic bomb attack.

Avoid downloading pirated software

Don’t click on suspicious links and avoid downloading software and files from shady websites. You never know which software is harboring a computer virus or logic bomb attack.

Download from reputable sources

If you’re downloading free software, make sure that you download it from a reliable source. Only visit websites that have a good reputation for hosting free software.

Keep your operating system up to date

Updates carry the necessary builds and bug fixes that patch the device with the latest security patches and fixing vulnerabilities.

Stay vigilant on the web

As always, practice good internet behavior where you’re cautious of suspicious links and email attachments.

Last but not least, train yourself and others around you to be cautious of such malicious attacks. Make a habit of reporting suspicious behavior to your seniors and subordinates.
