Emerging Attack Vectors in Cyber Security
In the field of Cyber Security, understanding attack vectors is crucial for safeguarding sensitive information and maintaining system security. An attack vector represents a method or path that cybercriminals exploit to infiltrate a network, system, or application by leveraging vulnerabilities. These vectors encompass the diverse techniques or routes that attackers utilize to access systems, networks, or applications without authorization, with the intent to exploit weaknesses, exfiltrate data, or cause harm.
As cyber threats continue to grow in complexity, it becomes increasingly vital to recognize and mitigate these attack vectors. This article delves into the various types of attack vectors, their implications on cybersecurity, and strategies to defend against them.
What are Attack Vectors?
Attack vectors refer to the specific methods or pathways that cybercriminals utilize to gain unauthorized access to systems, networks, or applications. These serve as entry points for malicious activities, allowing attackers to exploit security gaps. Ethical hackers often use tailored attack vectors to assess the security of target applications, whether they are web-based or mobile apps. They exploit vulnerabilities or flaws in systems to access data, cause disruptions, or take control.
Types of Attack Vectors
Below are some prevalent attack vectors in the realm of cybersecurity:
- Phishing: A social engineering attack where victims are deceived into clicking on malicious links designed to mimic legitimate ones. The most common phishing tactic involves spam emails that appear authentic, tricking victims into divulging sensitive credentials.
- Malware: Short for “malicious software,” malware refers to any program crafted to harm systems, networks, or users. These programs are typically designed to gain unauthorized access and benefit a third party without user consent.
- Man-in-the-Middle (MitM): This attack involves an unauthorized proxy intercepting and altering communication between two parties, effectively acting as a “man in the middle.”
- Denial of Service (DoS): A DoS attack disrupts network operations by overwhelming targeted systems with excessive requests, rendering them unable to process legitimate user actions.
- Insider Attacks: These threats originate from individuals within an organization, such as former employees, contractors, or partners, who have or had access to sensitive data.
- Ransomware: A form of malware that encrypts a user’s data, rendering it inaccessible until a ransom is paid.
- SQL Injection: This technique involves injecting malicious SQL code into web application inputs to gain unauthorized database access.
Recent Cybersecurity Incidents
- Infosys: In November 2023, a data breach impacted Infosys McCamish Systems, the US arm of the Indian IT company. The breach caused application downtime, and the investigation is ongoing.
- Indian Council of Medical Research: In October 2023, health data of approximately 815 million Indian citizens was exposed due to a breach attributed to a threat actor named “pwn0001.”
- Hyundai Motor Europe: In February 2024, a ransomware attack by the Black Basta group allegedly resulted in the theft of 3TB of corporate data.
- Boeing: In November 2024, Boeing experienced a cyber incident linked to the LockBit ransomware group. While business operations were affected, flight safety remained uncompromised.
Protecting Against Attack Vectors
Here are strategies to safeguard organizations from potential attack vectors:
- Network Segmentation: Dividing a network into isolated segments to limit access and enhance security. Each segment is separated using devices such as routers, switches, or firewalls.

Understanding the Attack Surface
The attack surface encompasses all potential points of access or channels through which attackers can infiltrate a system, network, or application. It includes vulnerabilities, access points, and possible pathways that exist within an organization’s digital environment
Insecure Direct Object Reference (IDOR)
IDOR is a vulnerability that enables attackers to manipulate or access resources belonging to other application users. This permission-based flaw often involves endpoints improperly securing access to sensitive data, including images, addresses, or login credentials. Due to the complexity of permission-based vulnerabilities, they often require manual intervention for resolution.
Relative Path Overwrite (RPO)
Discovered by security researcher Gareth Heyes, Relative Path Overwrite (RPO) exploits how browsers handle relative paths when importing CSS files into the Document Object Model (DOM).
- Relative Path Example:
<link href="database/xyz.css" rel="stylesheet" type="text/css"/>
- Absolute Path Example:
<link href="https://example.com/database/xyz.css" rel="stylesheet" type="text/css"/>
For instance, if the document loads from https://example.com/database, the CSS file loads from the relative path https://example.com/database/xyz.css. However, an attacker can manipulate URLs, such as changing https://example.com/index.html to https://example.com/index.html/random/payload, to control the CSS behavior by injecting malicious payloads into vulnerable endpoints.
By exploiting this behavior, attackers can manipulate the CSS of web applications, leading to unauthorized control or display modifications.
Phishing
Phishing is a form of online deception in which cybercriminals attempt to obtain sensitive information, such as passwords, credit card numbers, or bank account details. This is typically achieved by sending fraudulent emails or messages that appear to be from legitimate sources, such as banks or reputable websites. The goal is to trick individuals into sharing their information, allowing the fraudsters to misuse it. Always verify the authenticity of any communication before providing personal information.
What is a Phishing Attack?
Phishing is a type of cyber attack that derives its name from the word “phish,” akin to fishing. Just as bait is used to lure fish into traps, phishing employs deceptive tactics to trick individuals into engaging with malicious websites or emails. Attackers craft these sites to appear genuine, thereby misleading victims into providing confidential data. The most common method is sending spam emails that look authentic but are designed to capture credentials. Attackers use this stolen data for purposes like identity theft, impersonation, or data breaches.
Example:
In a phishing scenario, an email might mimic YouTube’s branding, prompting users to click on an extension. However, upon closer inspection, the URL may reveal it’s from “supertube.com” instead of “youtube.com.” Additionally, YouTube never requests extensions for watching videos. Such subtle discrepancies signal a phishing attempt.
How Phishing Occurs
Phishing attacks are carried out through various means, including:
- Opening Unverified Attachments: Attackers send mysterious files that either inject malware or prompt victims to enter personal data.
