Can You Get Hacked Without Clicking a Link?

There are many ways a malicious cyber criminal can gain access to a network, device, or user account without the victim clicking a link. Security tools are constantly being deployed and developed to detect malware from phishing emails, malicious websites, and compromised browsers. 

Black hat hackers have adapted to these security measures by using tools and features built-in to operating systems. These are applications that are used for computer management and automation are being abused. 

Yes you can, hackers can get into your system without you clicking on a link, using physical attacks that target Bluetooth, near-field-communication (NFC), bad USB, and more. Attackers also use “Living off the land” (LOL) techniques which are tactics used by malicious actors to leverage legitimate tools and features on a system to carry out their attacks. These techniques take advantage of software that is already present on the system, making it more difficult for security measures to detect and block the malicious activity.

One common example of a LOL technique on Windows machines is using Windows PowerShell to run malicious scripts. PowerShell is a powerful scripting language that is built into Windows and is commonly used by system administrators to automate tasks.

 Malicious actors can use PowerShell to download and run scripts that can be used to gather information, move laterally through the network, and execute other malicious actions.

Another example of LOL technique is using the Windows Management Instrumentation (WMI) to run malicious scripts.WMI is a Windows feature that allows scripts to be run on a remote machine, it can be used by an attacker to gather information about the target machine and run malicious scripts without the need of a payload.


How Can I Defend My Windows System From LOL techniques?

To defend against these types of LOL techniques, it is important to use best practices for hardening your systems, such as:

  1. Using the latest version of Windows and applying security updates regularly.
  1. Disable or restrict the use of PowerShell and WMI on endpoints, unless it is required for business operations.
  1. Implementing endpoint protection software that can detect and block malicious scripts.
  1. Use application whitelisting to only allow known and trusted applications to run on your systems.
  1. Regularly scan your systems for vulnerabilities and patch them.
  1. Use network segmentation and firewall policies to limit the spread of malware across your network.
  1. Conduct regular security assessments and penetration testing to identify and remediate vulnerabilities. 
  1. Educate your employees about the risks and best practices of using Windows and other software in a secure manner.

It is important to note that, since attackers are constantly improving their methods, it is essential to be vigilant and regularly review your security measures to ensure they are still effective against the latest TTP’s or tactics, techniques, and procedures.


What Windows Services do Hackers Use?

There are several Windows 11 services that can be abused by malicious users in order to carry out malicious activities; these are the LOL techniques. Some examples include:

  1. Remote Desktop Protocol (RDP): RDP is a service that allows users to remotely connect to a Windows 11 machine. It can be abused by malicious actors to gain unauthorized access to a system and move laterally within a network.
  1. Windows Management Instrumentation (WMI): WMI is a service that allows scripts to be run on a remote machine, it can be used by an attacker to gather information about the target machine and run malicious scripts without the need of a payload.
  1. Windows PowerShell: PowerShell is a powerful scripting language that is built into Windows and is commonly used by system administrators to automate tasks. Malicious actors can use PowerShell to download and run scripts that can be used to gather information, move laterally through the network, and execute other malicious actions.
