4 Common Cyber Attacks and How to Protect Your Business

As technology continues to advance, cyber attacks have become more frequent and sophisticated. Hackers are finding new ways to infiltrate networks and steal valuable data, targeting everyone from small startups to large corporations. With cyber threats becoming more complex, it’s crucial for businesses to understand the risks and take proactive steps to defend against them.

In this post, we’ll explore the four most common types of cyber attacks, how they affect businesses, and the best strategies to protect your company.

What Are Cyber Attacks?

Cyber attacks are malicious attempts by individuals or organizations to breach and control another entity’s network or system. Cybercriminals typically aim to steal, expose, or damage sensitive data, including financial information, customer records, and intellectual property. These attacks can lead to serious consequences, such as financial losses, reputational damage, and legal issues.

While anyone can be targeted by a cyber attack, businesses are particularly vulnerable. However, by improving IT security and enforcing strict internal policies, you can better protect your organization from these threats.

1. Malware

Malware, short for malicious software, includes a variety of programs designed to harm computers, networks, and servers. Malware can take many forms, including spyware, adware, Trojans, botnets, worms, and ransomware. Regardless of the type, malware often operates covertly, making it difficult for the victim to realize they’ve been compromised until significant damage has been done.

Ransomware is one of the most notorious forms of malware. A well-known example occurred in 2021 when the REvil hacker group targeted Quanta, a major Apple partner, with a ransomware attack. They demanded a $50 million ransom and released confidential Apple product blueprints when their demands weren’t met.

2. DoS and DDoS Attacks

A Denial of Service (DoS) attack is designed to overwhelm a network or website, making it inaccessible to legitimate users. Hackers achieve this by flooding the system with excessive requests, which causes it to crash or slow down.

A Distributed Denial of Service (DDoS) attack is a more advanced form of DoS. Rather than originating from a single source, a DDoS attack involves multiple compromised systems working together to target the victim. In 2020, Amazon Web Services experienced a DDoS attack that generated 2.3 terabits of data per second, lasting for three days. Although the attack didn’t cause severe damage, it highlighted the potential risks of lost revenue and brand damage from such incidents.

3. Phishing

Phishing attacks use deceptive emails, phone calls, or messages to trick individuals into revealing sensitive information, such as login credentials, credit card numbers, or personal identification numbers. Hackers often impersonate reputable companies or create fake websites that appear legitimate in order to gain the trust of their victims.

One of the most notable phishing attacks occurred between 2013 and 2015, when hackers tricked Google and Facebook into wiring $100 million by posing as Quanta, a Taiwanese supplier for both companies. The fraud was eventually uncovered, and the social media giants recovered $49.7 million, but it serves as a reminder of how easily businesses can fall victim to phishing scams.

4. SQL Injection

SQL injection occurs when an attacker manipulates a website’s database by injecting malicious code into the system. This attack gives hackers the ability to access or modify sensitive data, compromise user privacy, and even take control of the operating system.

In one of the most infamous SQL injection attacks in 2007, hackers targeted companies like 7-Eleven, Hannaford Brothers, and Heartland Payment Systems. The breach led to the theft of millions of credit and debit card numbers, affecting businesses and consumers alike.

How to Prevent Cyber Attacks

While it’s important to stay vigilant, having the right protective measures in place is essential. Here are a few key strategies to help safeguard your business against cyber threats:

1. Keep Software Updated

Regularly updating your software is one of the simplest yet most effective ways to protect your systems. Software updates often include patches that address security vulnerabilities, making it harder for hackers to exploit weaknesses. Make sure all devices, from computers to printers, are running the latest software versions.

2. Secure Input Devices

Office devices like printers and scanners are often overlooked in cybersecurity plans, yet they can be prime targets for malware. To protect your office devices, consider implementing print security audits. These services monitor printing activity, identify potential security risks, and recommend ways to strengthen device protection.

3. Limit Access Control

One of the best ways to protect your data is by limiting access to it. Restrict who has access to sensitive information and systems to reduce the risk of insider threats or accidental data breaches. Using centralized cloud storage can help ensure that only authorized individuals have access to critical data.

4. Train Employees

Awareness is the first step in preventing cyber attacks. Ensure that your employees understand how cyber attacks occur and know how to recognize phishing attempts and other threats. Conduct regular training sessions to educate staff on safe online practices and the importance of cybersecurity in the workplace.

Conclusion

Cyber attacks are becoming increasingly common and sophisticated, making it essential for businesses to take proactive steps to protect their data. By understanding the different types of attacks, staying vigilant, and implementing strong security measures, you can reduce the risk of a breach and keep your business safe.
