Understanding Critical Threat Vectors 2023

In the ever-evolving landscape of cybersecurity, one term that often arises is ‘threat vector.’ But what does it mean, and why should it be a central focus of your security strategy?

Simply put, a threat vector is a path or method used by cybercriminals to breach computer systems. These vectors might include malicious emails, infected websites, or even an employee’s actions within the organization.

Types of Threat Vectors

Threat vectors can broadly be classified into external and internal vectors. External vectors refer to threats from outside the organization, such as hackers or malware. On the other hand, internal vectors originate within the organization, usually involving employees or internal systems.

External Threat Vectors

Phishing Emails

Phishing emails are fake emails which are sent by attackers to lure users into providing personal information or sensitive information such as passwords, usernames , Social security numbers etc. The attacker pretends to be someone you trust and sends a email requesting such information.

Weak and compromised Passwords

Weak passwords are often gateway for attackers to gain unauthorized access to internal systems or networks. This will provide attackers user privileges. Attackers will start from low level privileges and move up to higher privileges with admin level access.

Web Applications

Web applications are programs and services that organizations make available for access on the internet. These include email, office suites, search bars, photo editors, and comments modules. However, vulnerabilities are often found in web applications, including the application servers hosting apps and databases that store their data. Because web applications are accessible on the internet, attackers can freely exploit their vulnerabilities to steal data or gain unauthorized access. For example, using the popular SQL injection attack, in which malicious queries are made to an SQL database, attackers can extract data such as passwords (in encrypted form) and credit card details. 

Drive by Download

A drive-by download occurs when malware is downloaded onto a device over the normal course of internet browsing, including legitimate and trusted websites. This happens because attackers have compromised the website with malicious code. In some cases, malware is downloaded after a user clicks on a link, a pop-up window, or advertisement. Attackers often masquerade their ads as attractive offers, warning messages, and browser update alerts to trick people into clicking. In other cases, malware is downloaded without any user interaction. This is made possible by vulnerabilities in the user’s internet browser that allows the attacker’s code to exploit it.   

Remote Access Services

Remote access services allow users to connect to remote systems and networks. Commonly used remote access services include virtual private networks (VPN) and Windows remote desktop services, which provide remote workers with complete access to their workstation using another device. However, threat actors can scan for instances of these remote connections on the internet. Once these are discovered, they can hack the connection by breaking into the user’s account using a brute-force attack or exploiting misconfigurations and vulnerabilities in the service. A successful breach of a remote connection gives hackers access to workstations and network resources just like normal users

Social Engineering

One prevalent threat vector is social engineering. This tactic manipulates individuals into divulging sensitive information, often through phishing emails or spoofing attacks.

Malware and Viruses

Malware and viruses remain a significant threat. Cybercriminals often exploit software vulnerabilities or trick users into downloading malicious software.

Unsecured Wi-Fi Networks

Public Wi-Fi networks pose another risk, as cybercriminals can exploit these connections to intercept data or launch man-in-the-middle attacks.

Importance of Understanding Threat Vectors

Assessing Potential Vulnerabilities

• Understanding threat vectors helps organizations identify potential vulnerabilities in their systems. With this knowledge, they can fortify their defenses and prepare for possible attacks.
• As vulnerabilities can be a access point for an attacker to break through security, it is highly suggested fortify them using regular updates and security check.

Enhancing Protection Measures

• By understanding the various threat vectors, organizations can devise effective security strategies. This might involve implementing advanced cybersecurity technologies or fostering a security-conscious culture among employees.

Internal Threat Vectors: An Overlook

Employee Mishandling of Data

Employees can unintentionally become a threat vector. This may occur through simple mistakes, such as sending sensitive information via unsecured emails. Data loss or leaks can also be due to phishing attacks which are mainly focused on employees

Insider Threats

Insider threats are threats that come from within an organization in the form of negligent and malicious employees. Negligent insiders are those who are generally aware of the organization’s security policies but choose to ignore them. For example, revealing their passwords and connecting to the intranet using public wi-fi or personal VPNs. These actions inadvertently give attackers an easy route into organization’s systems and networks. Malicious insiders are those who carry out malicious activities on purpose. They may have been bribed by threat actors to steal data like trade secrets and customer information or help them load malware onto systems.  

Threat Vector Identification and Management

1. Identification of Threat Vectors:
   • Discover potential threat vectors: Determine all possible entry points that attackers could use, such as network connections, email attachments, web applications, and physical access points.
   • Assess vulnerabilities: Evaluate the weaknesses within each potential threat vector, including outdated software, misconfigurations, weak passwords, and unpatched systems
2. Risk Assessment:
   • Prioritize threats: Evaluate the potential impact and likelihood of exploitation for each identified threat vector. This enables the prioritization of mitigation efforts based on the level of risk.
   • Quantify risks: Assign risk scores or ratings to each threat vector to understand their significance and potential impact on the organization’s assets, data, or operations.
3. Management of Threat Vectors:
   • Implement security controls: Deploy appropriate security measures to mitigate the identified vulnerabilities, such as firewalls, intrusion detection systems, access controls, and encryption.
   • Maintain up-to-date systems: Ensure that all software, applications, and systems are regularly updated with the latest security patches and fixes to address known vulnerabilities.
   • Enhance user awareness and training: Educate employees and users about common threat vectors like phishing attacks, social engineering, and malicious downloads. Promote safe online practices through security awareness training programs.

Transforming Threat Vector Understanding into Security Strategy

The Role of Real-time Detection

• Real-time detection plays a pivotal role in a security strategy. By identifying threats as they occur, organizations can respond quickly to mitigate damage.
• This could range from having security monitoring systems such as SIEM or End point monitoring systems which can keep monitoring the network activity for anything suspicious.

Importance of Comprehensive Asset and Network Visibility

• Complete visibility into network and assets is vital. It allows for quicker identification of vulnerabilities and provides insights into potential threat vectors.

The Human Factor in Threat Vector Management

Understanding Human Vulnerabilities

• Humans can often be the weakest link in a security strategy. By understanding human vulnerabilities, organizations can tailor their security measures to account for human error.
• As humans can be primary target for attacks such as phishing and other forms, they should be highly trained continuously for emerging security threats.

Training and Education

• A well-educated workforce is a strong defense against many threat vectors. Regular training on recognizing and responding to threats can reduce the risk of successful cyberattacks.
