When using devices, connecting to the network, making use of platforms, or installing programs we can encounter many threats. There are many types of malware that in one way or another can jeopardize our security and affect the proper functioning of our computers. Let’s take a look at what a logic bomb attack consists of. This is a type of malware that could seriously affect us and is part of the range of possibilities that cybercriminals have.
Logic bomb malware attacks
We can say that a logic bomb malware is based on inserting malicious code into a program and remains there hidden until the time comes and it is executed. The hacker in this case programs a series of actions to be performed by this malware once certain conditions are met.
This is a very dangerous type of attack, as the victim installs this software without any signs that something is wrong. Unlike many other varieties of malware, the effect is not immediate. We won’t notice the computer malfunctioning, shutting down, additional programs installed, or anything unusual.
We can name many types of malware that as soon as it is downloaded it affects the proper functioning. But in this case, things are different. With a logic bomb malware, we will not notice anything until the time comes and “explodes”.
This is undoubtedly a major disadvantage for the victim. He will not know immediately that the computer has been infected, so he will not take prompt action to try to mitigate the problem.
This type of threat is also known as a ticking time bomb. This is because the cybercriminal can schedule an exact date for it to be executed. But generally, something common in this type of malware is that it is executed when the user, the victim, in short, performs some action. For example, when opening the browser, installing a specific program, opening a file… The malware can be designed to act at that moment.
How logic bomb malware can affect us?
It should be noted that logic bomb malware can affect us in very different ways. It all depends on the malicious code introduced by the hacker and the actual target of the attack. However, the victim’s privacy is always at stake.
A logic bomb attack may be designed to delete files from the system. A cybercriminal might have created this malicious software with the sole purpose that opening a program, using some function of the computer, will execute the malware and delete files.
The objective may be simply to delete a type of file, specific folders, but also to empty memory or hard drive. This is logically a major problem that could affect vital information for a company.
Precisely the information is another of the objectives that they can have. Malware of this type may have been designed to collect data, steal personal or company information. It may be to sell to third parties, to extort money and threaten to offer it to competitors, etc.
It is necessary to bear in mind that nowadays our information has a great value in the network. we can be victims of campaigns of Spam, for example. Hence we should always keep our data safe.
Prevent access to programs or services
Another issue to bear in mind is that it could prevent access to certain installed applications or services that we use. It may block the connection, prevent us from logging in, or otherwise hinder the operation of that program.
For example, malware of this type could be designed to run in a certain company and prevent workers from accessing management applications, accounting, or any tool that is essential for everything to run smoothly.
Using our accounts
But something very important is the misuse of our accounts. A logic bomb malware could be designed to send an email in our name, for example. It would use our computer to conduct Spam campaigns or even compromise the security of other users.
Consume system resources
It could also be designed to consume system resources and squeeze the hardware to the maximum. This could result in significant performance loss, crashes, system shutdowns, etc. They could use this to mine cryptocurrencies, for example. Also to misuse the computer and once again send files in our name.
How to protect ourselves from this threat?
We have seen what a logic bomb attack is and how it could affect us. It is something we must avoid at all costs and protect ourselves adequately. That is why we are going to give a series of important tips to protect our computers and avoid becoming victims of this type of threat, as well as other similar threats that may affect us.
Use security programs
Something fundamental to protect ourselves from any cybernetic problem is to always use security tools. Having a good antivirus can help us prevent the entry of threats. This is something we should apply no matter what type of operating system we use. There are many options both free and paid.
But we are not only talking about antivirus, as we can also install a firewall, antispyware, or even browser extensions. All this can help us to keep our computers protected and avoid problems of this type.
Keeping equipment up to date
Undoubtedly another very important factor is to keep the equipment updated. On many occasions, hackers take advantage of vulnerabilities in the systems. These flaws allow the entry of malware, as in the case of logic bombs.
We should always keep all patches and updates available. This will correct these errors and prevent them from being exploited by third parties to put our security and privacy at risk.
Always download from reliable sources
It is always advisable to download from reliable sources and official software. Sometimes we can indeed find alternatives, with other varieties of software that may offer different functions and features. However, we may encounter problems. Therefore, it is highly recommended to download only from safe and reliable sites.
Use common sense
Common sense should not be forgotten. In most cases, hackers will require the victim’s interaction. For example, downloading an attachment that arrives in the mail, installing some type of software, or entering a web page.
At all times we must avoid making mistakes of this type that could affect us. It is essential to maintain security and not expose our data more than necessary. This will be essential to reduce the risk.
In short, a logic bomb attack is a very important problem that we must avoid. We have explained some tips to be protected at all times and reduce the risk of being attacked by this method.
