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.

2. Disable or restrict the use of PowerShell and WMI on endpoints, unless it is required for business operations.

3. Implementing endpoint protection software that can detect and block malicious scripts.

4. Use application whitelisting to only allow known and trusted applications to run on your systems.

5. Regularly scan your systems for vulnerabilities and patch them.

6. Use network segmentation and firewall policies to limit the spread of malware across your network.

7. Conduct regular security assessments and penetration testing to identify and remediate vulnerabilities. 

8. 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.

2. 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.

3. 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.

4. Scheduled Tasks: Windows 11 allows the scheduling of tasks to run automatically, malicious actors can use this feature to schedule malicious scripts/programs or remote access features to run at specific times.

To monitor these suspicious actions, you can use several methods such as:

• Use endpoint protection software that can detect and block malicious scripts and unauthorized access attempts.

• Use log monitoring and security information and event management (SIEM) tools to collect and analyze log data from multiple sources, such as Windows event logs, firewalls, and intrusion detection systems.

• Use network monitoring tools to detect and track suspicious network traffic and identify potential command and control (C&C) activity.

• Use application whitelisting to only allow known and trusted applications to run on your systems.

• Use intrusion detection and prevention systems (IDS/IPS) to detect and block malicious traffic at the network level.

• Conduct regular security assessments and penetration testing to identify and remediate vulnerabilities.

It is important to note that monitoring for suspicious activity is an ongoing process and requires constant attention and fine-tuning. It is always wise to regularly review your security measures, update your tools and techniques, and train your employees to be aware of potential threats are the keys to effectively detect and respond to malicious activity on your network.

It is always wise to update your security tools as well so they can detect the most recent malware, behavior analytics, and system performance. User awareness and employee training is paramount as well. This will especially cut down on the spread of malware, social engineering vulnerabilities, and more.

What Microsoft Tools Can Detect an Intruder or Malware?

There are several built-in Microsoft tools that can be used to detect a malware and cyber intrusions on a Windows 11 system, some of them are:

• Microsoft Defender: Microsoft Defender is an antivirus program that comes pre-installed on Windows 11. It uses a combination of real-time protection, cloud-based threat intelligence, and machine learning to detect and respond to malware and other malicious software. 

It can be found in the settings menu under the “Update and Security” tab, you can use it to perform a full scan of your system to detect malware.

• PowerShell: PowerShell is a powerful scripting language that is built into Windows. It can be used to run commands and scripts on a system. One of the built-in PowerShell command that you can use to detect malware is “Get-MpThreat”. 

This command will show you the current state of the malware protection on the machine and will list any threats found.

• Task Manager: Task Manager is a built-in tool that allows you to view information about the processes running on your system. You can use it to identify any processes that are consuming a large amount of resources or that are not associated with known applications. This can be an indication that a process is malware.

• Event Viewer: Event Viewer is a tool that allows you to view detailed information about system events and warnings. You can use it to review the logs for any suspicious events, such as unexpected shutdown, service failures, and security breaches.

• Control Panel: Control Panel is a built-in tool that allows you to view and manage the settings on your system. You can use it to view the installed programs, and check if there are any suspicious or unknown software on your system.
