In today’s rapidly changing digital environments, cybersecurity threats continue to plague businesses in every industry. Ensure your business remains protected by utilizing Fiverr freelance cybersecurity experts, staying up to date on the latest forms of cyberattack, and understanding your options.
Here are 10 of the most common cyber attacks used today and action steps you can take to avoid them:
A DoS (Denial-of-Service), or DDoS (Distributed Denial-of-Service) attack is a form of cyber corruption where critical systems and network services are targeted with the primary goal of making them inoperable. This can cause tremendous financial strain on businesses whose employees and customers need regular access to company websites and cloud-based applications and services.
Some useful ways to protect yourself from this form of attack is to deploy network monitoring solutions and draft a denial-of-service plan. Monitoring solutions will help automatically identify DoS attacks as they surface while denial-of-service plans help you provision resources in the event of an attack to keep your systems operational.
Zero-Day exploits are caused by unsafe or outdated software that creates IT security vulnerabilities not yet identified by developers. The term “zero-day” refers to the fact that development teams don’t currently have a patch or fix to these vulnerabilities, so they are easier to exploit and create security holes for cybercriminals to use.
Having a dedicated IT and cybersecurity team is a great way to mitigate your risk against Zero-Day exploits. Fiverr has an entire network of freelance cybersecurity professionals who can help you asses the integrity of your business systems with vulnerability assessments while keeping you protected from this dangerous form of cyber attack.
With more and more of our information being shared through digital formats and through mobile applications, the risk of transmitted data becoming compromised is high. MitM (Man-in-the-Middle) attacks involve hackers using session hijacking, packet injection, and SSL stripping to gain access to sensitive data transmissions between two parties. This can include banking transactions, legal discussions, and sensitive information sharing.
An effective solution for minimizing the potential of MitM attacks is to implement HSTS (HTTP Strict Transport Security) on your company website as well as establish SSL and TLS protocols. Hiring the right web developer is critical when ensuring your site meets these high standards in web security. Hiring vetted web design and cybersecurity professionals through Fiverr is a cost-effective way to get the experience you need to avoid MitM attacks across all of your networked systems and services.
SQL, or Structured Query Language, is a coding language used in relational database constructs and used on the backend of web applications and websites. During an SQL injection, the malicious code enters a database through various means allowing hackers to gain full access to the application's construct. Once the database is compromised, SQL injection commands allow hackers to view, modify, and remove website content or any other sensitive information the database stores.
In order to mitigate the risk of an SQL injection taking place, system administrators need to establish and configure company firewalls and appropriate access permissions to restrict database usage to only trusted sources. Reducing your network attack surface makes it easier to recognize unauthorized access and address security vulnerabilities if and when they occur.
Similar to SQL injections, XSS (Cross-Site Scripting) attacks are executed with the purpose of compromising web applications. However, unlike SQL injections, XSS attacks are designed to affect an application’s user base rather than the server it runs on. The primary goal of an XSS attack is to gather information about a website’s users, including cookie data, session IDs, preferences, and login information.
Defining a Secure Development Lifecycle (SDL) that identifies best security practices across products and applications is an effective way of ensuring XSS vulnerabilities are easier to spot and deal with. Using automatic source code scanning tools is another great way to address web vulnerabilities. Ultimately, however, having an established cybersecurity team to plan for and address XSS vulnerabilities is the most effective way to reduce cross-site scripting exploits.
An APT (Advanced Persistent Threat) is a stealthy form of data breach that can go undetected for several months, leading to long-term compromising of system data. Using advanced tools, hackers carry out APTs by countering system security processes, giving them unrestricted access to sensitive company data while remaining under the radar.
APTs can come from various outside and inside sources, so it’s important to do a thorough analysis of the integrity of your systems to recognise these threats early on as they develop. A great starting point to this initiative is to hire a team of "pentesters” (penetration testers) to analyse and report on your system vulnerabilities. The Fiverr marketplace offers a number of penetration testing services from industry professionals who are well-trained in ethical hacking and can help you identify APT risks that security software solutions may miss.

Ransomware is currently one of the most common and effective forms of malware that accounts for trillions of dollars in business losses each year. Ransomware is a lucrative form of exploitation for hackers that infects target systems and heavily encrypts and deletes stored data unless a hefty ransom is paid to release it. Sadly, many businesses are unable to recover from this form of attack.
Installing next-gen antivirus software and deploying properly configured firewalls is a good place to start when keeping your business protected from ransomware attacks. Because ransomware is often injected through exploit kits hosted on compromised websites, it’s important to set filters on your web browsers to ensure you’re only visiting secure, reputable websites and only downloading files when you’re sure they’re safe.
An insider threat is any form of a malicious threat that originates from inside an organisation. These threats can come in the form of employees who purposely compromise systems, those that are negligent and don’t follow safe security practices, and malicious external sources that pose as legitimate users through compromised login credentials. Since an insider threat originates behind company firewalls and external security measures, many times these threats can materialize into undetected, costly breaches to data security and system integrity.
In modern business security, it’s best to adopt a “zero-trust policy” when it comes to establishing strict access permissions and network monitoring solutions. While additional restrictions on internal system usage may seem like a drain on productivity, it’s a much more sustainable way to ensure your systems and networks remain uncompromised from the inside with the same security enforcement protocols as outside the organisation.

Social engineering is a broad term to describe various tools and techniques used to extract sensitive information through psychological manipulation. You can find popular forms of social engineering in email phishing schemes designed to mimic authority websites and platforms. In these schemes, malicious sources pose as authority websites and services in an effort to bait and hook victims into sharing login credentials, financial information, or other forms of sensitive data.
When it comes to social engineering prevention, security awareness and training for employees is essential. Often, ignorance of cybersecurity dangers leads employees to engage with shady characters who don’t have the company’s best interests in mind, creating new network vulnerabilities that weren’t there before. Fiverr provides a large pool of freelance security professionals who can help design and implement your company’s security-based policies.
By working with a team of dedicated cybersecurity experts, you can provide your employees with proven social engineering prevention tips and processes to keep your business protected from outside malicious sources.
Drive-by attacks refer to a form of stealthy malware delivery that requires little human intervention to succeed. Once you visit a corrupted website, drive-by attacks hide in lines of invisible code on a web page and are activated with no need to download a file directly. It then injects code onto a user’s system, creating a back door for hackers to steal information, compromise systems, and use system resources to run botnets and DDoS attacks without users even knowing.
To reduce the risk of falling prey to a drive-by attack, it’s important to install security software that contains a strong packet filtering firewall. This effectively detects anomalies in websites and can recognise dangerous patterns in their source code so they can be reported and avoided. It’s also important to pre-screen websites you’ve never visited by using free website checking solutions to identify websites that have been flagged by other internet security tools so you can steer clear of them.
Investing in the right knowledge and expertise is essential to maintain a strong cybersecurity posture in today’s digital landscape. Fiverr makes it easy for businesses to develop their own cybersecurity teams without any long-term commitments, while significantly reducing their operational costs.
