MALWARE: POLYMORPHIC &
METAMORPHIC
Malware,
as we know, can arrive in multiple ways. There are many threats that we can
find when surfing the net. We also have at our disposal multiple security
programs and tools with which to protect ourselves. However, not all types of
malware are equally dangerous. We can find ransomware, key loggers, and
cryptocurrency miners. Today we are going to talk about polymorphic and
metamorphic malware. We are going to explain why they can be so dangerous and
also give some interesting tips to protect ourselves.
What Is Polymorphic Malware?
When
we talk about polymorphic malware, we mean that one that has a "core"
that always acts in the same way. It doesn't matter how many times it changes.
He always performs the same actions and always attacks in the same way. Mind
you, it keeps modifying the rest of your code to keep your goals up to date.
Polymorphic
malware may be a bit easier to identify than metamorphic malware, which we'll
talk about now. This is so since the kernel can be detected to identify
malware.
This
type of threat can affect a system and, once it has achieved its objective,
that computer would generate a new variety of malware. They could even change
the name if it is an e-mail that is sent automatically. Yet the core remains
the same.
What Is Metamorphic Malware?
For
its part, metamorphic malware is much more dangerous. Whereas the polymorph has
a detectable core, the metamorphic malware tries to reorganize all its code
with each iteration. This means that it works in a similar way, but each act
adds different elements to the code. Also different functions rearranged so
that it looks different and is much more difficult to detect.
There
is nothing more dangerous than a type of malware that is difficult to detect.
If we are not able to know what type of threats we have, it will be difficult
for us to eliminate it and save our system.

are the 5 most common malware distribution methods so you can protect yourself
According
to experts, this type of malware is increasingly present in artificial
intelligence. This means that it can reach many more devices and become a
really serious problem for our day to day. That is why it is more dangerous.
As
we can imagine, computer security companies are trying their best to find a way
to deal with metamorphic malware. New products that can help combat these types
of problems.
How Can We Protect Ourselves From These Types Of Threats?
As
we have mentioned, it is a more dangerous variety due to the fact that it is
difficult to detect. That is why common sense is vital more than ever. Know how
to anticipate possible problems that compromise security. Do not download files
from unofficial or untrustworthy sites, avoid opening spam emails that may
contain malware, etc.
Similarly,
it is important to keep our systems updated. Vulnerabilities sometimes emerge
and are exploited by cybercriminals. The manufacturers themselves release
security patches to avoid this.
Finally,
always having a good antivirus and
other security programs and tools also helps prevent threats.
