Three prominent cybercrimes and their effective prevention strategies.

Within our expansive digital environment, our information is protected by Cybersecurity, which acts as a virtual bodyguard responsible for preserving the fundamental principles of Confidentiality, Integrity, and Availability (CIA). With its creativity and robustness, it serves our society as a defensive measure to prevent malicious activities and keep interconnected technologies secure.  

The past few decades have witnessed the emergence of globalization, which is marked by enhanced connections and collaborations among individuals, businesses, and governments around the globe. This remarkable progress has been accompanied by rapid technological advancements, taking us from the early days of the internet to the current era dominated by breakthroughs in Quantum, Cloud computing, Artificial Intelligence, and other cutting-edge technologies.

Throughout this journey, technology has consistently occupied a prominent position, driving progress and shaping the landscape of our interconnected world.

We are frequently referred to as Internet citizens or netizens, which indicates our extensive online presence and dependence on the Internet. In this constantly connected world, data, and information travel through networks at an unparalleled rate and pace.

As Internet and Communications technology (ICT) continues to gain prominence as the main means of sharing knowledge and information, the proliferation of devices like computers, smartphones, and wireless networks is expected to skyrocket in the future.

However, despite the advantages of technology, we must also acknowledge its potential disadvantages. It is important to understand and be aware of the dangers that come with these benefits.

To stay ahead, it is necessary to understand that we are all at risk of cyber threats. By educating ourselves about these risks, we can reduce the chances of becoming vulnerable to attackers.

This blog provides a concise summary of the three main cybersecurity threats that individuals and organisations face, giving readers the knowledge to strengthen their defenses and protect against possible attacks.

What are Cybercrimes?

Cybercrime refers to illegal activities conducted using electronic devices, like computers, and a reliable internet connection. The objective is to compromise the security of computer systems and the information they contain.

Perpetrators of cybercrime engage in unlawful actions to obtain unauthorised access to private data belonging to individuals or organisations. This can involve stealing personal information for identity theft, selling illegal products or services, carrying out scams, or causing disruptions to normal operations.

Cybercrime covers a wide range of illicit activities conducted through digital platforms, to exploit weaknesses and cause harm.

Who are the individuals involved in these activities?

Cybercriminals can generally be classified into three primary groups:

1. Seeking recognition. This category consists of people who desire recognition or fame within specific circles. It encompasses enthusiasts who dabble in hacking as a hobby, hackers with political motivations, and individuals affiliated with terrorist groups who aim to assert their beliefs or promote their ideologies by means of cyber assaults.

2. Cyber mercenaries.  Operating in secret, cyber mercenaries pursue financial gain through hacking activities. Their objectives include selling stolen data, providing hacking services to clients, and executing targeted attacks in exchange for monetary rewards. Their primary concern is to maximize profits while minimizing the chances of being detected by law enforcement.

3. The insiders.  This group comprises people who possess internal knowledge or have access to confidential information within organisations. It may consist of former employees seeking revenge, rival companies employing hackers to gain economic advantages through sabotage or theft, or individuals with special access who exploit their positions for personal gain. The reasons behind cybercrime often arise from greed, a craving for power or recognition, revenge, a sense of excitement or thrill-seeking, or purely a destructive mindset.

Which are some of the most prominent cyberattacks one should be aware of?

1. Phishing. It is the cunning art of deceiving people into revealing personal information, like passwords or credit card details, under false pretenses. This crafty scheme is often carried out through email or SMS, where scammers pose as trustworthy organisations. To convince their targets, these fraudsters will go to great lengths, mimicking the appearance of well-known brands and crafting URLs that closely resemble the real ones. They'll even play on emotions, using urgent or fear-inducing language to pressure recipients into immediate action. Phishing relies on exploiting human weaknesses and manipulating psychology, making it all too easy for individuals to unknowingly disclose sensitive information.

2. Distributed Denial of Service (DDoS). DDoS has the objective of making a computer resource inaccessible to its intended users. In these attacks, the perpetrator overwhelms the victim's systems or floods their network with useless traffic, resulting in legitimate users being denied access or services being disrupted. The main purpose of DDoS attacks is usually to disrupt the smooth functioning of websites or related services. Attackers often focus on high-profile web servers like payment gateways, mobile phone networks, or domain name servers. For instance, they might target Apple's services on the day of a new product release to cause disruptions for its customers. These attacks are called distributed because they involve multiple computers, typically compromised systems controlled by the attacker. In a DDoS attack, these compromised systems are coordinated to launch simultaneous attacks on a specific target. While the main victim is the primary target, the compromised systems used in the attack are also considered victims. DDoS attacks present significant challenges to ensuring the availability and Integrity of online services, emphasizing the need for robust cybersecurity measures to minimise these threats.

3. Trojan Horse. They are malicious programs that pretend to be legitimate software in order to trick users into downloading and installing them on their systems. Even though they may seem harmless, once installed, they carry out a hidden malicious script, giving attackers unauthorised control over the victim's system.

These malicious programs can do various harmful activities, such as gaining unauthorised access to the system, allowing attackers to remotely control it, disabling important system functions like the control panel or task manager, significantly slowing down system performance or damaging and overwriting data. Trojan Horses are often used as carriers for other types of malwares, like ransomware or keyloggers, which makes them very dangerous and capable of causing significant harm to affected systems.

To distribute Trojan Horses, social engineering techniques that exploit human psychology are frequently used. For instance, they may appear as fake software updates or come as email attachments, enticing users to unknowingly install them through deceptive methods.

What can be done to protect oneself from falling into these traps?

1. Browsing the web securely. When browsing the internet, make sure to give preference to websites that have secure and encrypted connections, like the ones with HTTPS in their URLs. HTTPS shows that the website is using the SSL protocol, which means it has an SSL certificate that improves the security of your data while it's being transmitted. Before connecting to public Wi-Fi networks, it's advisable to set up a Virtual Private Network (VPN) to encrypt your data traffic and protect your privacy.

2. Installing updated software and antivirus protection. Antivirus programs constantly refresh their signature databases to keep up with the ever-changing dangers. These signatures act as guides for recognising harmful files found on the internet. By comparing signatures with encountered files or websites, antivirus software can differentiate between safe and potentially dangerous content, thereby assisting users in safely browsing the web.

It is crucial to regularly update operating systems, software applications, and antivirus programs to defend against new threats. These updates frequently contain fixes that address known weaknesses and enhance system security.

3. Implementing strong passwords and credentials. To prevent dictionary brute force attacks, it is essential to create strong and intricate passwords. This can be achieved by combining uppercase and lowercase letters, numbers, and special characters while meeting the minimum length requirements.

Adding an extra layer of security through two-factor or multi-factor authentication is highly recommended whenever possible. This strategy, known as defense in depth, strengthens protection by requiring users to verify their identity using multiple authentication factors.

Cybersecurity goes beyond mere responsibility; it signifies a shared dedication to safeguarding the security, resilience, and immunity of our digital realm in the face of constantly evolving cyber threats.

By engaging in mutual learning and collaboration, we pave the way for a more secure digital world.
