The Top 10 Most Common Cybersecurity Threats

In today’s interconnected world, it’s vital to understand the most common types of digital security attacks. Let’s take a look at the ten most common ones so you can be prepared.

1. Phishing Attacks

Phishing attacks take advantage of emails, text messages, or websites, and trick users into revealing their passwords, credit card numbers, or other sensitive information. These techniques often involve impersonating reputable organizations, creating a sense of urgency, or employing emotional manipulation tactics. 

2. Malware Infections

This relies on software designed to harm or exploit computer systems. Ransomware, one of the most popular types of malware, encrypts a user’s computer and effectively locks them out of it until they pay the attacker a ransom fee. 

A Trojan horse is another form. It comes in disguise and is designed to make users think it’s a legitimate, desirable program, when in fact it contains obscured malicious functions. These cause data loss, financial loss, and unauthorized access to information.

3. Password Breaches

Passwords are a powerful tool for protecting your digital information. However, hackers still have ways to obtain them, including:

  • Brute-force attacks use automation to try to guess a password 
  • Dictionary attacks methodically use lists of words in hopes of coming up with correct passwords
  • Password cracking tools use a variety of specifically designed computer programs such as Hashcat, John the Ripper, and Brutus to uncover passwords

Hackers are gifted login thieves, and it’s crucial to have strong, unique ones that you change regularly. You should also use two-factor authentication to help increase your online security.

4. Social Engineering

Some attackers con people into giving confidential information by engaging in pretexting and fabricating a situation to convince victims to provide them with information. On social media, they may falsely claim to be friends with somebody the victim knows and use the relationship to get them to disclose their credit card details. These hackers may also use a strategy of baiting, making alluring offers or promises of rewards to trick unsuspecting individuals into divulging sensitive information. Being cognizant of these threats and remaining skeptical online helps you defend yourself against these would-be attackers.

5. DDoS Attacks

Distributed Denial of Service (DDoS) attacks harm a business financially and hurt their reputation by disrupting websites using an unmanageable volume of artificial traffic, thereby making it inaccessible to legitimate users. A company can protect itself by maintaining a strong network with the proper firewalls and also by using DDoS recognition and mitigation services. 

6. Insider Threats

An organization’s staff may pose a threat to cybersecurity by compromising confidential data for their own benefit. Therefore, It’s vital to have monitoring protocols and strong user accessibility controls to minimize threats.

7. Spoofing

Hackers using this form of attack falsify the source of an email or other communication to make recipients believe they’re engaging with a trusted, legitimate company, organization, or person. This can lead to financial fraud and unauthorized information sharing. Vigilantly verifying sources of communication can prevent these spoofing attacks.

8. IoT Vulnerabilities

According to IBM, the Internet of Things (IoT) “refers to a network of physical devices, vehicles, appliances, and other physical objects…embedded with sensors, software, and network connectivity that allows them to collect and share data.” These devices may lack proper security measures, making them vulnerable. However, changing devices’ passwords and keeping IoT networks separate from critical systems negates the risks. 

9. Zero-Day-Exploits

Zero-day exploits target yet-to-be-discovered software vulnerabilities. Hackers find and use these flaws to wreak havoc on a system before security patches and updates are in place. Monitoring risks and installing antivirus software can help defend against these attacks.

10. Cloud Security Risks

As more businesses are depending on cloud-based services, it’s important to address the inherent security risks including data breaches and unauthorized access. Encrypting data and regularly monitoring cloud environments go a long way toward ensuring cloud security.
