When it comes to surfing the web, there are many threats that we can find. There are many types of malware and attacks that in one way or another can compromise our systems and devices. In this article we are going to talk about what a dropper is and how it can affect our security. We will also give some tips on how to protect ourselves and avoid being victims of this problem.
What is a dropper
When we talk about dropper we refer to a type of Trojan that is capable of installing some other variety of malware , such as a virus, backdoor, keylogger … Basically what it does is deposit that malicious software on the target system. That malicious code, that malware ultimately, is inside the dropper.
A dropper prevents the antivirus from detecting the threat. After all, the malicious code is hidden and it is that dropper that introduces it into the system to infect it. It usually comes in several stages, so the dropper downloads the remaining malicious code through the network or through the file itself, to later write to the disk and execute it.
They can use some component to deceive the victim . For example, a file that pretends to be a legitimate program, a game, an image … In this way, it enters the victim’s system without suspicion. The problem is that, as we can see, it carries malicious code inside that it then executes on the computer.
There are droppers that only inject malware into memory. In this case they are also known as injectors .
In short, a dropper is a type of malware that is normally not detected by antivirus. This makes it difficult to prevent our computers from being infected. Therefore, we must always take precautions to avoid being victims of this problem.
How to avoid falling victim to a dropper
We are going to explain what we can do to avoid being victims of this type of attack that can compromise the security and privacy of our systems. A dropper, as we have seen, is a major problem. However, we can prevent it from infecting our computers.
Common sense
Something fundamental is common sense . We must avoid downloading software that may be dangerous, such as programs installed from third-party and insecure sites. It is also vital not to make mistakes such as when opening an email that may contain malicious attachments and somehow infect us.
Hackers often rely on mistakes that users make. In this way, they manage to sneak malware onto devices and carry out their objectives.
Security tools
Although in this case the antivirus can not always detect the problem, it is equally important to have security software that protects our computers. We have at our disposal a wide range of possibilities, with both free and paid options.
This is something that we must apply at all times. It does not matter what operating system or type of device we are using. We must always install this type of security tools that protect us adequately.
Keeping equipment updated
On the other hand, having updated devices will also be essential to avoid security problems. There are many occasions when vulnerabilities arise that are exploited by hackers to attack. Thanks to patches and security updates we can avoid problems that compromise us.
Therefore, something fundamental and that we must always take into account is to have the latest versions. This should be applied to all types of software that we have installed, operating systems and devices.
In short, a dropper is one of the many threats that we can find on the Internet. It is very important that we take measures to avoid being victims of this problem that can cause equipment to malfunction and put our privacy at risk, a factor highly valued by users and not always present.
