The Top 5 Cybersecurity Attacks You Need to Know About in 2021
Introduction
As businesses and individuals depend more heavily on technology, the need for cybersecurity has never been more apparent. Cyber attackers become more prevalent and diverse with every passing year, and 2021 is no exception. This article highlights the top 5 cybersecurity attacks that you need to be aware of in 2021.
Ransomware Attacks
Ransomware attacks are a significant threat for businesses in 2021. Ransomware encrypts data, making it unavailable to owners. Attackers then threaten to release it unless a ransom is paid. In recent years, there have been several high-profile attacks that resulted in huge demands, sometimes running into millions of dollars! Be aware of phishing emails, use strong passwords, and always update security software to avoid ransomware attacks.
Distributed Denial of Service (DDoS) Attacks
DDoS attacks are designed to prevent access to resources, typically by overloading servers. Cybercriminals use various techniques to create a massive volume of traffic, causing the server to be overloaded and eventual downtime. This attack’s consequences can lead to reputational, financial, disputes with customers, and information loss for businesses. Always make sure that your system has robust defense against DDoS attacks.
Phishing Attacks
One of the most common types of cybersecurity attacks, phishing attacks, occur when cybercriminals use emails or messages that appear to originate from trustworthy sources. When users click on links or download attachments from these sources, their systems can be infected, and data stolen. Always be wary of links that you are not sure of and avoid clicking on them.
Cyber Insurance Fraud
Businesses in 2021 face a new form of cybersecurity attack that relates to cyber insurance fraud. Cybercriminals have started targeting companies that have insurance policies related to cybercrime. They commit crimes that do not involve any data loss but fake a breach, and the organization files a claim. This can often lead to extravagant claims leading to a loss in the company’s reputation and lower insurance coverage when they need it direly.
Insider Threats
Employees pose a significant threat to businesses and their cybersecurity. Companies must protect themselves against insider threats that can come from intentional or unintentional actions of their employees. Employees must be trained to identify threats within the organization, report, and cybercrimes to appropriate authorities before they occur.
Conclusion
In conclusion, the cybersecurity threat landscape in 2021 has never been more daunting. As the year progresses, it is essential to keep a close eye on these five threats to avoid becoming a target. By taking a few simple steps, such as updating security software, creating strong passwords, and being vigilant, businesses and individuals can stay protected from these cybersecurity attacks that made our list.
