Dll Hijacking Attack In Cyber Security

-

DLL stands for dynamic link library.



Here is a video to watch if you don't have time to read the whole article:



 

Every operating system has DLL files.

 

This is a library used to share files and resources on the operating system to run programs and applications.

 

DLL is the foundation for running an operating system for efficiency and productivity.

 

DLL files contain the code that programs and applications can use and share to run on the operating system without the need to install a new file every time you run a new program or an application.

 

Many programs and applications can even use a single DLL file at the same time.

 

Remember efficiency and productivity.

 

This is how DLL files work on the operating system when you run an application or a program.

 

When you open an application, your operating system searches for the required DLLs in a certain order.

 

This search order includes the application and system directories.

 

When the DLL file is loaded in the memory, any application on the operating system that needs the code inside that DLL can use it at the same time.

 

A hacker can take advantage of this process and execute a DLL hijacking attack in the following way:.

 

They can place a malicious DLL file with the same name as the real one on your system.

 

You might ask, How did that get into my system in the first place?

 

Well, maybe you clicked on a phishing link that was sent to your company email. Any way.

 

When you run an application on your system, it will use that malicious code inside the fake DLL file.

 

This happens by taking advantage of weak file permissions to write or replace DLLs in directories where applications have write access.

 

By placing a malicious DLL in a directory where the application looks for DLLs, the attacker can trick the application into loading the malicious code instead of the real library file.

 

DLL hijacking can be used as one step in a broader attack strategy.

 

Like privilege escalation, for example, and taking control of your computer and organization files.

 

The best way to prevent this type of attack is to implement secure coding practices by developers and always update and patch your systems.

 

Thank you for watching the whole video.

 

Remember, don’t click on links that you are not sure about, and use a VPN.

 

Stay safe, and I will see you in the next one.

  Bluebugging Attack Bluebugging is a silent attack that allows malicious hackers to silently sneak into Bluetooth-enabled devices without the users ever realizing it. Here is a full video to watch if you don't have time to read the full article:    It is the houdini of cyber attacks.   It sneaks into your devices without you even knowing!   It's the ultimate stealth mode for hackers.   Imagine someone gaining access without leaving a digital footprint!   Bluebugging can be the starting point of another relevant attack called bluesnarfing.   This is the sneaky cousin of bluebugging, grabbing your information without you suspecting a thing.   Bluesnarfing is a related technique where the attacker gains unauthorized access to information on the target device, such as contact lists, calendar entries, or messages, without the user's knowledge.   But today, we focus on the fundamentals of Bluebugging attack.   Bluetooth, the technology t...

  What Is Eavesdropping In Cyber Security Hello friends,   Today is about eavesdropping. Here is a video to watch If you don't have time to read the article:   This is a technique used by hackers in order to intercept electronic communications.   It involves a third party secretly listening to or monitoring communication without the knowledge or consent of the parties involved.   Hackers can use different methods to implement this technique, like:   Packet sniffing, which is basically intercepting and analyzing data packets as they travel across a network. On the other hand, there is Wiretapping, which is physically tapping into communication lines to intercept conversations. And finally, man-in-the-middle attacks, in which the attacker intercepts and potentially alters the communication between two parties,.   Given the nature of this attack, different actions can be taken for prevention and protection.   Like encrypting end-to-end communication ...

Fileless Malware Attacks In Cyber Security

  Fileless Malware Attacks In Cyber Security Hello friends. Today we talk about fileless malware attacks. If you don't have time to watch the whole video, check this video on my YT channel:  These types of malicious attacks happen without the need for traditional executable files to be stored on a system's hard drive. Unlike other malware that relies on files to execute malicious actions, fileless malware operates by residing in the system's volatile memory, aka RAM. These attacks are based on stealth and evasion. It can evade traditional security measures, making detection and mitigation more challenging for antivirus programs. These types of attacks leverage scripts and system tools to carry out malicious activities directly in the computer's memory. This allows attackers to blend in with normal system activities. Detecting and mitigating fileless malware requires advanced cybersecurity measures. Let’s use analogies to explain these types of attacks. Imagine your comp...
