Cyber threats on the rise: how to safeguard your data

Cyber threats are on the rise. Learn what they are and how to protect yourself in this comprehensive guide. Don't wait until it's too late!

August 23, 2023

If you work in cybersecurity, you understand how dangerous internet attacks can be. Cyber dangers range from infiltrations of key infrastructure and data breaches to spear phishing and brute force assaults, and they do not discriminate between businesses and people when looking for a victim.

You've probably heard the phrase "cyber threat" tossed about in the media, but do you really know what it means? A cybersecurity threat is defined as any harmful act that seeks to harm, steal, or disrupt data and digital life in general. Computer viruses, data breaches, and Denial of Service (DoS) assaults are all examples of such attacks.

To really understand the notion of cyber dangers, it is necessary to go further into the history of cybersecurity. The dangers and consequences of these threats continue to rise as we navigate an increasingly linked world. So, let's have a look at what cyber risks are and how to avoid them.

What is a cyber threat?

A cyber threat is a harmful activity committed with the intent of destroying, stealing, or disrupting data and digital life in general. Computer malware, data breaches, and Denial of Service (DoS) assaults are examples of these risks. As we depend more on technology, cyber dangers have progressed and grown more pervasive, presenting a substantial risk to persons and enterprises. Understanding cyber risks is the first step in defending yourself from them.

What are the consequences of cyber-attacks?

In recent years, cyber-attacks have grown more widespread. No one is immune to the danger of a cyber attack, from huge enterprises to government institutions. The hazards connected with data breaches and cyber assaults are rising as more sensitive information is kept and shared online. 

These are some of the consequences of a cyber attack:

  • Electrical blackouts
  • Failure of military equipment
  • Breaches of national security secrets
  • Theft of valuable and sensitive data (like medical records, sw code)
  • Computer and phone network disruption
  • Paralyzation of entire systems
  • Encrypt critical information, making data unavailable

It’s not an exaggeration to say that cyber threats may affect the functioning of life as we know it.

The threats are growing more serious, too. Gartner explains, “Cybersecurity risks pervade every organization and aren’t always under IT’s direct control. Business leaders are forging ahead with their digital business initiatives, and those leaders are making technology-related risk choices every day. Increased cyber risk is real — but so are the data security solutions.”

The Department of Homeland Security (DHS) collaborates with various federal departments to carry out significant criminal probes to counter and overcome cyber offenders. They emphasize hiring and educating technical specialists, establishing uniform approaches, and widely disseminating cyber response techniques and resources.

Types of cyber attacks 

Cyber attacks take various forms, each with its own set of techniques and objectives. We have put together a list of the Top 7 cyber threats that could put your business at risk. Understanding these types of cyber assaults is a critical first step in defending yourself and your company from possible dangers.


Software that performs a malicious task on a target device or network, e.g. corrupting data or taking over a system.

Mobile devices are also vulnerable to malware attacks just like other computing hardware. Attackers may embed malware in app downloads, mobile websites, or phishing emails and text messages. Once compromised, a mobile device can give the malicious actor access to personal information, location data, financial accounts, and more. Here are some common types of malware:

  • Virus: This type of malware attaches itself to clean files and spreads throughout a computer system as those files are executed. It can quickly corrupt or delete data on a device.
  • Worm: Worms infect entire networks of devices either by local networks or through the internet. They operate by exploiting vulnerabilities in operating systems.
  • Trojan: Unlike viruses, Trojans don’t replicate themselves, but they can be just as destructive. They disguise themselves as legitimate software but act maliciously once inside the device.
  • Spyware: As its name implies, this type of malware spies on users. It can gather data like user habits, logins, credit card information, and other personal details.
  • Ransomware: This malware locks or encrypts data on a victim's device and demands payment (ransom) to restore access.
  • Phishing: An email-borne attack involves tricking the email recipient into disclosing confidential information or downloading malware by clicking on a hyperlink in the message.
  • Spear Phishing: A more sophisticated form of phishing where the attacker learns about the victim and impersonates someone he or she knows and trusts.
  • Adware: While not always malicious in intent, adware presents unwanted advertisements to the user, which can lead to other types of malware being installed.
  • Rootkit: These are designed to gain administrative access to a device. Once they do, they become deeply embedded and are difficult to detect and remove.
  • Keylogger: This malware records every keystroke a user makes, capturing passwords, login credentials, and other personal information.
  • Botnet: This is a network of compromised devices that are controlled remotely by an attacker, usually to carry out large-scale attacks or to send spam.
  • Fileless Malware: Unlike traditional malware that relies on files, fileless malware resides in a system's RAM and exploits legitimate programs to infect a computer.
  • Mobile Malware: As mentioned in the article snippet you provided, this targets mobile devices and can include a range of malicious software types tailored for these devices.

“Man in the Middle” (MitM) attack

This happens when an attacker establishes a position between the sender and recipient of electronic messages and intercepts them, perhaps changing them in transit. The sender and recipient believe they are communicating directly with one another. A MitM attack might be used in the military to confuse an enemy.

Denial of Service attack or Distributed Denial of Service Attack (DDoS)

DDoS is when an attacker takes over many (perhaps thousands) of devices and uses them to invoke the functions of a target system, e.g. a website, causing it to crash from an overload of demand.

Attacks on IoT Devices

IoT devices like industrial sensors are vulnerable to multiple types of cyber threats. These include hackers taking over the device to make it part of a DDoS attack and unauthorized access to data being collected by the device. Given their numbers, geographic distribution, and frequently out-of-date operating systems, IoT devices are a prime target for malicious actors.

Data Breaches

A data breach is a theft of data by a malicious actor. Motives for data breaches include crime (i.e. identity theft), a desire to embarrass an institution (e.g. Edward Snowden or the DNC hack), and espionage.

SQL Injection

An SQL injection is a cyber assault where harmful code is introduced into a server using Structured Query Language (SQL). Once compromised, the server divulges data. This malicious input can be done simply by typing it into a susceptible website's search field.

Password Attacks

If a cyber intruder possesses the correct password, they can unlock a trove of data. Social engineering is a form of password attack, which is defined as "a tactic where attackers largely depend on human engagement, frequently deceiving individuals into bypassing usual security measures." Other password attack methods encompass breaches of password repositories or direct attempts at guessing.

Causes of cyber attacks

Understanding the origins of cybersecurity assaults is a critical step in designing successful prevention and mitigation techniques.

  1. Human Error: Individual errors, such as clicking on phishing sites or failing to follow security measures, may expose systems and networks to attack.
  2. Outdated Software: Failure to update software and security systems on a regular basis may expose networks and devices to fraudsters who are continuously finding and exploiting new vulnerabilities.
  3. Inadequate Authentication: Weak passwords, a lack of two-factor authentication, and failure to revoke access to departed workers may expose systems to attack.
  4. State-sponsored cyber assaults aiming at stealing intellectual property, obtaining military or political advantage, or destroying essential infrastructure.
  5. Attacks carried out by one country against another, frequently with the goal of disrupting or harming essential infrastructure such as power grids or banking systems.
  6. Tech Providers with Weak Security Posture: Many organizations rely on third-party technology providers for various services, ranging from cloud storage to software applications. If these tech providers have inadequate security measures in place, it creates potential entry points for cybercriminals.

Most common sources of cybersecurity threats

Cyber threats come from a variety of places, people, and contexts. Malicious actors include:

  • Individuals that create attack vectors using their own software tools
  • Criminal organizations that are run like corporations, with large numbers of employees developing attack vectors and executing attacks
  • Nation-states
  • Terrorists
  • Industrial spies
  • Organized crime groups
  • Unhappy insiders
  • Hackers
  • Business competitors

Nation-states are the sources of many of the most serious attacks. There are several different versions of nation-state cyber threats. Some are basic espionage— trying to learn another country’s national secrets. Others are aimed at disruption.

For example, Chris Painter of the U.S. Department of State commented in a Brookings Institution article that China and North Korea “have frequently exercised their cyber power to achieve their strategic goals around the globe.”

He noted, though, “Their motivations and objectives differ: While North Korea primarily aims to develop capabilities for revenue generation and destructive capabilities for potential conflicts outside North Korea, China mainly utilizes its cyber means for espionage and intellectual property theft. “Naming and shaming” has been an effective tool against China because of its government’s concerns on the potential blowback on its soft power.”

These are the so-called “cyber weapons” that might be used to shut off electricity in enemy territory during a war. In some countries, the boundaries between criminal organizations and national intelligence are blurred, with the criminals doing the actual work of cyber espionage.

Many cyber threats are bought and sold on the “dark web,” a disorganized but widespread criminal segment of the Internet. In this online bazaar, aspiring hackers can buy ransomware, malware, credentials for breached systems, and more. The dark web serves as a multiplier for threats, with one hacker being able to sell his or her creation over and over.

How to prevent cyber threats: safeguarding your sensitive data

Securing your sensitive information is more crucial than ever before in the ever-evolving world of cyber threats. The fallout from a single data breach can be catastrophic, impacting your privacy, financial stability, and reputation. Luckily, there are numerous strategies you can employ to protect your valuable data. Here are some essential steps to consider:

  1. Update Regularly: Keep your operating system, software, and apps up-to-date with the latest security patches. Hackers often exploit outdated systems, so it's essential to regularly check for and install updates.
  2. Strong Authentication: Utilize strong, unique passwords for each of your online accounts. Consider using a password manager to help you keep track of complex passwords. Enable two-factor authentication (2FA) whenever possible for an extra layer of security.
  3. Secure Networks: Avoid using public Wi-Fi networks for sensitive transactions. If you must use public Wi-Fi, use a virtual private network (VPN) to encrypt your data and keep it private.
  4. Firewall and Antivirus Software: Use a firewall to block unauthorized access to your computer. Install reputable antivirus and anti-malware software to detect and remove malicious software.
  5. Be Wary of Phishing Attempts: Be skeptical of unexpected emails, especially those that ask for personal information or prompt you to click on a link. Verify the sender's identity before responding or clicking on any links.
  6. Limit Access: Restrict access to your sensitive data. Only share it with those who absolutely need it, and be sure to revoke access when it's no longer necessary.
  7. Data Encryption: Encrypt sensitive data, particularly when it's stored on portable devices like laptops or USB drives, which can easily be lost or stolen.
  8. Regular Backups: Regularly back up your important data to an external drive or cloud storage. This ensures that you have a copy of your data in case of a cyber attack like ransomware.
  9. Employee Training: If you run a business, train your employees about the risks of cyber threats and how to prevent them. This includes safe internet usage, recognizing phishing attempts, and reporting any suspicious activities.
  10. Incident Response Plan: Develop an incident response plan so you know what steps to take in case of a data breach. This should include who to contact, how to contain the breach, and how to notify affected individuals.
  11. Stay Informed: Stay informed about the latest cyber threats and prevention strategies. Join forums, subscribe to newsletters, or follow cybersecurity experts on social media.
Remember that cybersecurity is a continuous process and requires ongoing vigilance to protect your sensitive data effectively.


Finally, cyber threats are a real worry in today's digital environment, and they must be taken seriously. They may have a serious influence on anyone, from individuals to corporations to governments. However, prevention is essential, and there are several measures that may be used to lessen the danger of a cyberattack.
