What is a cyber attack?

A cyber attack refers to an individual’s or organization’s malicious attempt to infiltrate others’ network systems. Scammers use cyber attacks to illegally obtain information and use it for some type of benefit.

Among the most commonly used tactics include phishing, malware attack, ransomware, and denial of service.

Cyber incidents began even before the internet was invented. In 1834, the first record was in France when criminals illegally accessed the French Telegraph System and stole financial information.

However, cyber attacks gained a strong footing towards the end of the 20th century.

The technological advancements experienced in the 21st century have made it more sophisticated.

The Center for Strategic and International Studies (CSIS) highlights cyber attacks as one of the world’s greatest challenges today.  

Apart from individuals, government agencies, high-tech companies, and defense organizations are vulnerable to cyber attacks, causing losses of up to millions of dollars.

Statistics of Cyber Attacks

Research shows that businesses experience cyber attacks every day. A portion of them report the cases while others do not know they have been compromised.

According to a report developed by Cisco, the period between 2016 and 2017 saw a quadruple increase in cyber attacks. They disrupt, damage, and destroy businesses.

IBM states that it costs an organization $4.88 million to overcome a cyber attack. This amount is lost bit by bit when the organization experiences downtime, discovers a breach, takes the necessary steps to respond, and fixes reputational damage.

More sophisticated attacks are more costly. Some victims have lost  $40 million due to ransomware in one instance.

Additionally, some businesses have also lost  $47 million due to Business Email Compromise (BEC). Apart from the money lost to scammers, businesses also face regulatory fines, legal action, and loss of customer trust.

Research shows that by 2025 the world will be facing a loss of $10.5 trillion annually.   

Cybercriminals launch an attack for different reasons. Some commit petty thefts while others are paid to start an act of war.

Every year, individuals and businesses experience an increase in the number of cyber attack attempts. Attackers in search of ransom try to benefit from vulnerable systems.

As a result, more than 50% of cyber attacks have led to losses amounting to $500,000. Also, some people use cyber attacks to cause political and social effects (hacktivism).  

Common Types of Cyber Attacks

1). Malware

Malware is a term used to refer to malicious software. It includes worms, viruses, ransomware, and spyware. Scammers attract victims using an infected link or attachment.

When you click on the link or open the attachment, it installs malware causing a vulnerability in the network. Scammers then use the vulnerability to access and misuse your information.

2). Phishing

Cybercriminals use phishing to launch an attack. This method involves sending fraudulent messages, usually in the form of an email that appears to come from legitimate sources.

Phishing messages ask for personal information like passwords and identifying information. When you respond to the message, any data you provide goes to the scammer who uses it to commit fraudulent crimes.

3). Denial of Service Attack (DoS)

In this type of cyber attack, scammers jam network systems and servers. As a result, the high traffic exhausts bandwidth and resources, failing to fulfill required requests.

When the services slow down or stop, attackers can then extort money or information from the intended users. While it is challenging to successfully prevent these attacks, more preventive measures are being put in place to mitigate this threat.

4). SQL Injection

SQL which is pronounced “sequel” stands for the structured query language. This type of cyber extortion integrates malicious code into a server that uses Structured Query Language (SQL). The code causes the server to uncover information that is confidential to the user.

5). Man In The Middle Attack (MITM)

This type of cyber attack is also referred to as eavesdropping scam. It occurs when a criminal gets access to communication between two people through an unsecured public Wi-Fi or a malware attack.

The attacker can monitor and alter the contents of the communication without being noticed. MitM attacks can help criminals steal personal information.

Tools and Strategies to Prevent Cyber Attacks

As an individual or organization, you should have a threat management strategy that can be of help to detect and protect against cyber attacks. The strategy includes measures like:

i). Multi-factor authentication and Strong Password

You can protect your devices and accounts using multi-factor authentication and unique passwords. Multi-factor authentication adds another security level to your accounts by verifying your identity each time you log in.

A strong and unique password also prevents attackers from guessing it, ensuring only you can gain access.

ii). Virtual Private Network (VPN)

VPNs can help prevent potential attacks when using unsecured Wi-Fi. Scammers can access your information through vulnerabilities in unsecured networks. However, VPNs fill these vulnerabilities by hiding your web activities.

iii). Firewalls

Firewalls are tools that block malicious actors from accessing a network. If a device has malware, it works by preventing it from taking commands from a control server, hence, taking any information from the device.

iv). Consistent Learning

You can only detect a cyber attack if you know cyber attacks while continuously learning. They are likely to come up with new techniques as technology advances.

AI, specifically, has equipped them with more sophisticated skills. As a result, make sure you keep up with the new trends regularly to easily prevent an attack.

How to Detect a Cyber Attack

It is impossible to prevent cyber criminals from launching attacks. However, you can use early detection strategies to prevent any damage and report the incident.

First, be aware of suspicious links and attachments. Scammers integrate malware and ransomware attacks in links and attachments.

Also, be on the lookout for sites that do not use HTTPS. Secure networks have valid certificates and are, therefore, safe Internet communication platforms.

Lastly, you can use software that can detect any malicious attempts in your network. An antivirus such as Kaspersky or Avast can help you figure this out.

Large organizations can use Security information and event management (SIEM) systems to track internal cybersecurity tools.
