Malware Inside Anti-Virus – ICSS

Malware Inside Anti-Virus – ICSS

Cyber is not always fun, so today, let’s take a look at a term that keeps a lot of security professionals up at night; especially of a Malware inside antivirus.


****Malware is malicious software that is a cover-up term for viruses, worms, trojans, and other harmful computer programs hackers use this for destruction and gaining access to victims’ sensitive information. In other words, the software is identified as malware based on its intended use, rather than a particular technique or technology used to build it.

So now you all will think what is the difference between Malware and Virus? So the Answer is very Clear, a virus is a type of malware, so all viruses are malware (but not every piece of malware is a virus).

Let’s see where are the places these malware actually hides :

Now Let’s see how Antivirus Software work :

Antivirus software works by scanning files or code that’s being passed through network traffic. Companies who build this software compile an extensive database of already known viruses and malware and teach the software how to detect flags, and remove them.

When files, programs, and applications are moving in and out of any computer, the antivirus compares them to its pre defined database to find matches. Matches that are similar or identical to the database are scanned, and removed.

While you can adjust settings so that the antivirus can runs automatic scans of the computer system for malicious files, you can also opt-in for manual scans, which let you sit and see in real-time which malicious files are found and being neutralized.

Some antivirus software will ask for permissions before “cleaning” a file to remove malicious code. If you prefer a hands-off approach, you can still adjust the settings so the software automatically removes the malicious files.

Most antivirus software performs the same functions, so choosing between one brand and another shouldn’t be that complex decision.

Exploiting :

Antivirus software does not offer any protection against attacks of vulnerable network services, for example, an outdated web server. Because in such attacks, malicious code, so-called shellcode, is directly loaded into the main memory of the affected system and executed there, for example by exploiting a buffer overflow vulnerability. Thus, there is no file containing the malicious code within the file system of the target system that could be found by the usual malware detection mechanisms of antivirus software.

Now let’s dig into Why these Malware Hide inside an Antivirus Software :

If anyone wants to inject malware into your system what will be the easiest way for him? The Answer will be they will pretend to be nice to you and say to you, “Hay! you don’t have antivirus in your system someone can inject malware into your system so before they do that Install an Antivirus it will protect your System. If you don’t mind you can use my Antivirus for free”. It’s Human nature that whenever someone hears that this trusted person is giving something for free that too for their own good. In this situation when the victim trust and installs the antivirus which is embedded with malware the malware inside that get triggered and doesn’t let the antivirus software get installed. At this time you will not understand why this is happening. But you already become a victim of the attack.

Now How you can Protect yourself from Such attacks :

  • The most Important thing is Never Never Never Download anything from an unknown Site.
  • If someone offers you a free Software never take from them and better search for their official site and Download from there.
  • Scan full system twice a week. This will help your system from Malware and other Different types of Attacks.
