Understanding Attack Vectors: The Key to Reducing Your Organization’s Attack Surface

In 2023, it is more important than ever to implement a strong cybersecurity roadmap that aligns with potent attack vectors.

Over the last couple of years, the widespread change in work setups, dominated by the shift towards employees working off-premises, has affected the global cybersecurity landscape. There has been a tangible and significant increase in threats, with cyber criminals exploiting “misaligned networks.” In 2020, there was a 358 percent increase in malware attacks over the year before that, a trend that continued in 2021 and 2022. By the third quarter of 2022, “approximately 15 million data records were exposed worldwide through data breaches” an increase of 37 percent compared to the previous quarter. As we enter 2023, the frequency and severity of these attacks are expected to continue rising.

To survive and thrive in this landscape, it is important to take proactive measures to protect yourself from potential attacks. This involves identifying and addressing vulnerabilities, understanding potential points of compromise, and implementing appropriate prevention and detection measures to achieve cyber resilience. It is also crucial to be aware of the various methods that attackers may use to disrupt your business. According to Gartner, the changes in the way we work, combined with the greater use of public cloud, highly connected supply chains, and use of cyber-physical systems have created new and challenging attack “surfaces,” leading to a surge in attack vectors.

What are Attack Vectors & Attack Surfaces?

An attack vector is a pathway that a hacker uses to take control of an organization's IT infrastructure – gaining unauthorized access to sensitive data and disrupting business operations. Imagine a thief wanting to steal a valuable object from a store. They would have to enter and exit the vault – and the greater the gaps in security, the more the number of ways in which the thief can make their way in. The thief could exploit vulnerabilities such as unguarded backdoor or a faulty alarm system or use deception and pretend to be a member of the store staff. All of these methods represent attack vectors. Digital systems have various potential entry points that attackers may try to use as vectors. Because modern computing systems and application environments are complex, there are countless potential attack methods such as social engineering attacks to credential theft and exploitation of vulnerabilities.

The total number of attack vectors available to an attacker together constitute the “attack surface” of an organization. This means that the expansion of attack surface signifies a rise in the number of attack vectors that an attacker can use to manipulate or hack into a computer system. To reduce its attack surface, an organization must eliminate as many attack vectors as possible. While it is not possible to ensure that all attack vectors in an organization are closed off, a key feature of any comprehensive cybersecurity plan is to identify and secure as many of them as possible. 

Attack Vector Exploits

To exploit attack vectors, an attacker typically follows a series of steps:

  1. Identify a potential target who will be vulnerable to attack.
  2. Gather information about the target using various methods such as automated vulnerability scanning or phishing.
  3. Identify attack vectors using the information gathered, i.e., the potential ways of accessing the target.
  4. Use tools to exploit vulnerabilities and gain unauthorized access to the system.
  5. Steal data or install malicious code.
  6. Monitor the system to continue stealing additional information or using its resources.

A threat actor can choose to exploit an attack vector for a range of malicious purposes. Depending on their intent, the exploits can broadly be divided into two types: active and passive. Passive attacks aim to access information without affecting system resources, such as phishing or typosquatting. Active attacks seek to alter a system or its operation, such as malware, patch vulnerability attacks, and ransomware.

Most Common Attack Vectors to Watch Out for in 2023

The trends of the previous year and expert predictions for the year ahead indicate that some initial attack vectors top the list when it comes to exploitation by threat actors.

Phishing Emails

Social engineering comes in many forms, and phishing is the most common and insidious of them. Phishing emails continue to be a popular initial attack vector among threat actors due to ease of execution. Hackers utilize sophisticated techniques to generate well-executed business email compromise attacks (BEC) along with malicious URLs. In 2022, more than 255 million phishing attacks were recorded within a period 6 months – a 61 per cent increase over 2021. Attackers have become more sophisticated with their methods, investigating potential victims to gather information to create target phishing attacks that are more likely to be successful. 

Preventing end-user negligence will be the critical differentiator in protecting against social engineering attacks. Organizations should consider automation- and AI-based security solutions that provide a more robust defense against phishing attacks by conducting network-level analyses. Enabling monitoring and measurement of web browsing and email click-through behavior of end users and devices can also provide critical insights. 

Supply Chain Attacks

A supply chain attack occurs when a vendor's products, services, or technology are hacked, which, in turn, harms the customer base. In recent years, supply chains have increasingly become a frequently exploited attack vector. The growing trend of outsourcing further adds to this, since it engages multiple vendors who can all pose a huge cybersecurity risk to proprietary data. Some sophisticated threat actors can even breach the target network by leveraging a supplier’s network’s privileged access. Gartner predicts that by 2025, 3x the number of companies in 2021 are likely to face attacks on their software supply chains.  

Given the complexity of supply chain processes, organizations must seek out endpoint security solutions that mitigate risks end-to-end and strengthen their overall security posture. Reliable solutions incorporate features such as screening for inbound malware, detection of suspicious behavior of supply chain-derived applications and tools, and blocking unauthorized attempts to access files. 

Compromised or Weak Credentials

Usernames and passwords are the most common type of access credentials and are often exposed through data leaks, phishing scams, and malware. When lost, stolen, or exposed, these credentials can give attackers unrestricted access to an organization's systems. Weak and reused passwords also increase the risk of a data breach. Compromised credentials can bypass perimeter security and complicate detection, and the risk they pose depends on the level of access they provide. Privileged access credentials, which give administrative access to devices and systems, pose a higher risk than consumer credentials. Servers, network devices, and security tools, too, have passwords to facilitate inter-device integration and communication. If a threat actor gains access to these machine-to-machine credentials, they can move throughout the enterprise with almost unrestricted access.

To reduce the risk of compromised credentials leading to security incidents, it is essential that organizations have strong password policies that require employees to create secure passwords and prevent them from sharing or reusing passwords. Organizations should invest in security solutions that incorporate password managers, two-factor authentication, multi-factor authentication, etc.
