Now let’s discuss the common types of cyber attacks in 2023:-
Malware
Malware Malware refers to malicious software designed to harm or exploit computer systems, services, and networks, aiming for data extraction by cybercriminals for financial gain.
It targets various sensitive information like:-
Finances
Healthcare records
Emails
Passwords
Personal identification numbers
Banking details
Credit card numbers
Debit card numbers
Besides this, the malware also targets government and corporate sites as well for the following two key purposes:-
Data theft
Operational disruption
Here below, we have mentioned all the types of malware:-
Viruses
Ransomware
Scareware
Worms
Spyware
Trojans
Adware
Fileless malware
Phishing
Phishing Phishing a ttacks trick victims for the attacker’s benefit, and it’s been performed mainly via emails, ranging from simple to complex and not only that even Phishing attacks are:-
Extremely low-cost
Effective
Attackers mimic trusted sources, using bait-like messages to trick victims. Besides this, Phishing attacks lead to:-
Malware
Identity theft
Data loss
Targeting personal information
Targeting business information
Threat actors exploit phishing to access accounts, compromise systems, and initiate major data breaches as well. Phishing often backs harmful actions like on-path and cross-site scripting attacks, usually via email or instant message.
Denial-of-Service (DoS) Attacks
Denial-of-Service (DoS) Attacks Denial-of-service (DoS) attacks disrupt a device’s normal function to make it unavailable. This happens by flooding it with multiple requests, which causes the denial of service to users.
If the attack comes from various sources like a botnet, then it’s called a DDoS (Distributed denial-of-service) attack. In short, the DoS attacks overload a machine to deny additional requests.
DoS attacks typically fall into 2 categories, and here below, we have mentioned them:-
Buffer overflow attacks
Flood attacks
DoS uses one connection, and DDoS deploys multiple sources, often a botnet; however, the attacks share similarities, as the threat actors use one or many sources of malicious traffic.
Code Injection Attacks
Code Injection Attacks Code Injection involves injecting code into an application, and with the help of this attack, threat actors exploit the poor handling of untrusted data.
Besides this, the lack of proper input/output validation often makes these attacks possible.
Code Injection is unrestricted by injected language functionality, like PHP. In contrast, Command Injection uses existing code to execute commands, often in a shell context.
Vulnerabilities vary in discoverability and exploitation difficulty. While the successful exploits may lead to:-
Confidentiality loss
Integrity loss
Availability loss
Accountability loss

Injection flaws are often found in:-
SQL
LDAP
Xpath
NoSQL queries
OS commands
XML parsers
SMTP headers
Program arguments
IoT-Based Attacks
IoT-Based Attacks Advancements in the technological world enabled wireless connectivity for several types of smart devices:-
TVs
Watches
Lights
While the Internet of Things (IoT) automates these devices, equipped with sensors to collect and relay data for:-
Monitoring
Action
With the growing use and adaptability of IoT, cyber-attacks are actively targeted on connected devices. Though IoT devices enhance daily tasks but bring cybersecurity risks, especially for less-secured gadgets like-
Smart TVs
Wearables
Here below, we have mentioned all the common reasons why hackers target IoT devices:-
Weak passwords
Unsecured cloud storage
Unpatched software
Insecure network connections
Lack of encryption
Physical tampering
That’s for the secure operation of your IoT devices, it’s always recommended to stay vigilant and take all the necessary security measures.
Identity-Based Attacks
Identity-Based Attacks Nowadays, organizations face frequent cyber threats like Identify-based attacks, which are evolving rapidly and becoming:-
Complex
Sophisticated
These types of attacks are targeted by hackers who are actively looking for personal and sensitive data.
In telecom and beyond, Identity-Based Attacks are rising threats with significant consequences. Organizations must defend against various attacks like:-
Credential stuffing
Password spraying
Phishing
While regular password changes and the implementation of multi-factor authentication (MFA) will surely help to prevent these threats effectively.
In total, there are five types of Identity-Based attacks, and here below we have mentioned them:-
Credential Stuffing
Golden Ticket Attack
Kerberoasting
Man-in-the-Middle MITM Attack
Silver Ticket Attack
Supply Chain Attacks
Supply Chain Attacks Supply chain attack targets an organization’s weak links, exploiting trust in third-party vendors. It’s an island-hopping attack relevant across industries.
While this attack rising due to new tactics, it tampers with manufacturing processes to cause disruptions by exploiting the flaws in:-
Hardware
Software
These types of attacks are hard to detect, as they spread through trusted software, affecting organizations with many customers.
A supply chain attack aims to harm by infiltrating and disrupting a weak link in an organization’s system, often by targeting a vulnerable third-party supplier. Identifying the weakest point allows hackers to concentrate on the main target.
Spoofing
Spoofing Spoofing fakes trusted sources in emails, calls, or websites, even using technical tricks like IP or DNS spoofing. It’s a sneaky way to:-
Snatch personal info
Spread malware
Dodge controls
Launch cyber attacks
So, successful attacks mean infected systems, data breaches, and revenue loss, spoiling an organization’s reputation. Traffic rerouting can flood the networks or even direct the users to malicious sites for the following two key illicit purposes:-
Information theft
Distribution of malware
Spoofing spans communication methods with varying technical expertise. It executes phishing scams to grab sensitive info.
While here below, we have mentioned the types of Spoofing attacks:-
Email Spoofing
Caller ID Spoofing
Website Spoofing
IP Spoofing
ARP Spoofing
DNS Server Spoofing
Insider Threats
Insider Threats Insider threats arise within an organization involving employees or partners with valid access. Whether intentional or accidental, they endanger the network security, which leads to compromised data integrity.
Besides this, most data breaches result from insider threats, as traditional cybersecurity neglects all the internal risks.
However, the familiarity insiders have with systems and vulnerabilities gives them an exclusive advantage. Tackling insider threats requires equal severity to external threats in cybersecurity strategies.
Here below, we have mentioned all the types of insider threats:-
Malicious Insider
Careless Insider
Negligent insider
Compromised insider
DNS Tunneling
DNS Tunneling DNS Tunneling encodes program data in DNS queries that enable the control of remote servers.
Besides this, it also demands the following things to fulfill its illicit goals:-
External network access
A compromised system
Control over a domain
Authoritative server for execution
DNS is crucial for internet navigation, as it interprets the domain names to IP addresses. That’s why organizations trust it, and it’s allowed through firewalls.
DNS tunneling exploits this trust and uses DNS requests as a command and control channel for malware. Inbound traffic commands the malware, while outbound exfiltrates data.
The flexibility of DNS allows for carrying sensitive info, making this attack vector simple and effective with various toolkits available.
