What is a Cyberattack?

A cyberattack is an unauthorized access, use, manipulation, or exploitation of your systems, network, and/or resources. Cyber attacks are usually carried out by malicious individuals or groups utilizing malicious code, software, and other means to steal data, and sensitive information, disrupt company operations, or cause damage to the whole organization.

Types of Cyberattacks

Some examples of common cyber attacks and data breaches include:

Malware

Malicious software, or malware, refers to intrusive, malicious programs designed to exploit target systems, causing inconvenience to users while benefitting the attacker. Malware can have various types, but all of them are designed to evade security controls and dupe users into installing them into their systems, operating secretly without permission.

Some common types of malware include:

• Ransomware: A type of malware that can lock/encrypt your computer or important files and then demand a ransom for their release.
• Trojans: This type of malware is disguised as an attachment in an email or an important downloadable file to get transferred onto a user's device. Trojans can collect sensitive data from a device, including login credentials, payment information, etc.
• Spyware: Spyware lets a hacker collect information about a target device's activities by secretly transmitting data from the storage. Spyware can also function as a keylogger, as well as take screenshots of sensitive data.

Password Sniffing

Password sniffing involves hackers intercepting login credentials as they traverse a network. Hackers use methods such as packet sniffing or man-in-the-middle attacks to gain access to usernames and passwords.

Access Breaching

Access breaching involves unauthorized individuals gaining entry into your systems or accounts through various means, such as stolen credentials, weak security protocols, or exploiting vulnerabilities in software or hardware.

Identity Theft

It's a form of fraud where cybercriminals steal or misuse someone's personally identifiable information, such as their name, social security number, or financial information without their consent. Cybercriminals can also use identity theft to infiltrate an organization and steal sensitive information while pretending to be someone from the organization. Hackers can use various methods to steal personal information such as hacking databases, malware, phishing attack, etc.

Stolen Personal Devices

Stolen or lost devices, such as laptops or mobile phones, pose a risk of exposing sensitive information stored in them. These devices may store personal information, login credentials, or confidential business data, which can lead to privacy breaches, financial losses, or identity theft.

Distributed Denial-of-Service (DDoS) Attacks

DDoS or Distributed Denial-of-Service is a type of cyberattack where cybercriminals use multiple compromised devices, known as botnets, to flood target systems or networks with overwhelming traffic or requests. DDoS attack aims to disrupt the normal functionality of the targeted system, rendering it unavailable to legitimate users.

Infiltrated Systems

Some cyber criminals exploit vulnerabilities in the security defenses of a target's infrastructure, such as outdated software, weak passwords, or misconfigured systems. Once the attackers have successfully infiltrated the systems, they can execute various malicious activities, including data theft, unauthorized data modification or deletion, installing malware or backdoors, and reconnaissance for further attacks. Cybercriminals infiltrate systems to extract valuable information or use the compromised infrastructure for other nefarious purposes.

Website Defacement

Website defacement is the unauthorized alteration/modification of a website's content and appearance by malicious individuals or groups. In a defacement attack, hackers take unauthorized access to a website's backend or content management system (CMS) and make changes to the visible elements of the website. These modifications made during a website defacement attack can include altered website content (text, images, videos), altered graphics (logos, banners, etc.), or messages to convey their intentions, demands, or ideologies.

Website defacement attacks can occur from various vulnerabilities in a website's security, such as weak passwords, unpatched software, or improper server configurations. These attacks may take place to spread political or ideological statements, from personal grudges, or simply to seek recognition among hacker communities. These attacks can have detrimental consequences to the targeted organizations, resulting in reputational damage, loss of customer trust, as well as potential financial repercussions.

Web Browser Exploits

Web browser exploits involve cyber criminals leveraging malicious techniques or browser vulnerabilities to target and compromise web browsers used in an organization. Hackers take advantage of security weaknesses in web browsers, their plugins, or related components to gain unauthorized access, execute malicious code, or steal sensitive data. Exploits targeting web browsers can include Cross-Site Scripting (XSS), drive-by downloads, zero-day exploits, phishing attacks, etc.

Instant Message Exploitation

Sometimes attackers use social engineering attacks or exploit vulnerabilities within instant messaging platforms to gain access or compromise the security of an organization's communication channels. These attacks target messaging applications and the users who use them for real-time communication, such as employees, partners, or clients. IM exploitation can be used for different cyber attacks such as malware attacks, social engineering attacks, account takeover, message tampering, etc.

Intellectual Property (IP) Theft

Intellectual property theft is the unauthorized acquisition, use, or misappropriation of someone else's intellectual property or assets without permission or legal rights. Some cybercriminals employ various tactics to target and steal proprietary information, trade secrets, patents, copyrights, or trademarks owned by individuals, organizations, or institutions. These tactics can involve data breaches, insider threats, espionage, website defacement data alteration, etc.
