It is essential to be careful while online and to understand the threats you may face. While some cyberattacks are obvious, logic bombs are so sneaky that you don’t discover them until it’s too late — if at all.
If your computer is running fine, here are some key signs to look for that reveal a logical bomb attack. They are not easy to detect, but vigilance and good antivirus software can counteract them.
What are logic bombs?
Essentially, a logic bomb attack involves a virus that attaches itself to code on your computer and runs under certain conditions, whether the calendar is up to a certain date, someone is typing on the keyboard, or a new spreadsheet is being created.
Such logical malware could be intended to collect sensitive information, tamper with data, erase files, or block access altogether.
The tricky part is that logic bombs don’t always go off all at once and in an eye-catching way. They can activate multiple times, do their job, and fall back asleep without you or your cybersecurity even noticing.
How to detect logic bomb attack
The best way to learn about a logic bomb is to pay attention to your computer’s behavior, learn its system from back to front, and investigate anything that seems strange.
Start with the following guides that are as much about your online activity as they are about unusual errors in your computer. If you check many of these boxes, make the most of the best malware removal tools on the market, but contact an expert as well.
1. There is a strange code on your computer
The logic bomb virus needs to embed itself in your computer for it to work. Therefore, one way to detect such an attack is to regularly check all the coding.
Whether you do it yourself or hire a professional, check your operating system and software, especially anything important that you use often or that contains sensitive data.
If you find a symbol that shouldn’t be there, like Logic Bomb Examples for GitHubYou might be dealing with a cyber attack.
Before removing malware from your system, they can also tell you what it was designed to do.
2. Files disappear or change
Even if you don’t detect the code right away, there are several behaviors your computer can exhibit that indicate a logic bomb attack. It all depends on the purpose of the virus.
If the malware creator goes after the documents, for example, you may find changes that you can’t explain. They can disappear completely or have additional files in their folder. Any such inconsistency could be someone trying to tamper with the data.
3. Personal information changes without your input
One of the most obvious indications of a cyber attack with a logic bomb is that your sensitive details are being changed but not by you.
The form you fill out may have something different from it – a phone number, a reference, an income, etc. Your password for an online account may suddenly be wrong, forcing you to create a new one.
This is a good reason why you should always be aware of what you are doing on your computer. If you tend to forget about very busy days, you can use event log management tools or just write down your activities on paper.
4. Your sensitive data expires online
Despite your best efforts, you may find someone using your credentials, information on your computer, external hard drive, or another specific location that is not easily accessible.
If you suspect a hacking functionality but there is no evidence of other viruses or any alarm bells going off, check for logic bombs. They can be very stealthy and are good at not turning on cyber security while stealing personal data.
5. Your computer “explodes” with inexplicable problems
On the other hand, there are logic bombs that are fake to wreak havoc, which are a common tool in ransomware attacks, and their influence is evident in US cybersecurity statistics.
When the condition of such a bomb is met, it explodes and can cause any kind of damage, from locking or destroying important files to sharing customer details online.
Even if you don’t get a ransom request, your computer suddenly behaves without an apparent problem, even after an expert checks it out, indicating that there may be a logic bomb behind it.
6. Your access is restricted for no reason
As mentioned earlier, this type of malware attack can prevent you from accessing your computer, programs or online accounts.
If something like this happens and you’re sure you or your coworker didn’t change your password, it’s time to look for a logic bomb and alert anyone else who might be affected.
7. Your use of a suspicious file or website
A good question to ask is how the malware got into your system in the first place. The answer could be as simple as visiting a dangerous domain or clicking on a link that you shouldn’t have.
Judging by the types of worms around you, for example, attackers can go to your email, website, phone, and more, to plant a silent logic bomb instead of a trojan.
So, if your computer behaves in any of the above ways and remembers accessing or downloading something unusual, you may be on the trail of a logic bomb attack.
8. The activity of a staff member is suspicious
It is also common for logic bombs to find their way into corporate networks with the help of an insider. It could be a disgruntled employee or someone who wants to take advantage of a company and take advantage of it.
All they need is to download the virus to a computer or transfer it via a USB drive. Whatever the purpose of the bomb, it can easily start working from there.
It is possible to counter such an attack with good and updated anti-malware software and by closely monitoring employees, especially those who leave work and external partners, but you have to let your guard down in some cases point.
If you think you’ve discovered the effects of the logic bomb, think again about anyone who might have acted suspiciously or profited from the attack. It’s more detective than IT work, but it can point you in the right direction and highlight ways to improve your security.
Master cybersecurity and discover logic bomb attacks more easily
If you have the determination and money to invest in the safety of your business, do everything you can to give your technologies the best possible defenses. This will enhance your ability to counter logic bomb attacks before you can act, let alone get into your computer network.
In addition to making the most of antivirus services and keeping employees alert, you can resort to additional measures such as bots for internal devices used by workers and even ethical hacking. Above all, never stop learning about online threats and how to counter them.
