Understanding top cybersecurity threats: What they are and how they work

Cyber threats are potential dangers or harms that compromise security and data. Individual hackers or criminal networks can target anyone or any entity that relies on technology.

Cyber threats involve exploiting vulnerabilities in the target's digital infrastructure. These vulnerabilities can be found in software, hardware, network configuration, or even in the human elements of a system. Once a vulnerability is identified, the threat actors use different techniques to hijack the system. After that, they can gain access to your system without you knowing.

Various types of cyber security threats

The landscape of cyber threats is as vast as it is diverse. Each of these threats has its unique characteristics and modes of operation.

Ransomware: This cyber threat involves malicious software (malware) that encrypts the victim's data and demands a ransom to restore access. A chilling real-world example is the 2021 Colonial Pipeline ransomware attack that led to fuel shortages and panic buying.

Phishing: This involves sending emails or messages to trick the recipient into revealing sensitive information (like passwords or credit card numbers) or downloading malware. The 2016 cyber attack on the Democratic National Committee involved such a tactic.

Distributed Denial of Service (DDoS): In this type of attack, internet traffic is directed toward a specific server, causing overload and disrupting the entire system. In 2020, Amazon Web Services experienced a DDoS attack. 

Advanced Persistent Threats (APT): These are long-term, stealthy attacks where the attacker gains access to a network for a long time. The 2014 Sony Pictures hack is a prime example of an APT, resulting in confidential data leaks and unreleased films.

In cybersecurity, "vulnerability" refers to a weakness or loophole in a system that hackers can exploit. A deeper understanding of these vulnerabilities forms the bedrock of robust cybersecurity measures. Here, we will discuss the 4 main types of vulnerabilities and their role in cyber threats.

Software Vulnerabilities: These are flaws or bugs in software code that can control your system.  The infamous Heartbleed bug is one example, where a bug in the OpenSSL cryptographic software library led to massive data leaks.

Hardware Vulnerabilities: These involve physical devices and the firmware they run on. One example is the Meltdown and Spectre vulnerabilities that affected nearly every computer chip in the last 20 years. This attack allows hackers to steal data directly from the memory of hardware devices.

Network Vulnerabilities: These relate to flaws in a network's design, implementation, or configuration. An unsecured Wi-Fi network, for instance, can allow an attacker to intercept data being transmitted over the network.

Human Vulnerabilities: People are often the weakest link in cybersecurity. This includes falling for phishing scams, using weak passwords, or inadvertently downloading malware. The 2016 Democratic National Committee email leak exploited human vulnerabilities through an attack.
