Common cyber threats faced by businesses
There are numerous cyber security risks to be aware of, and experts, such as those who have completed a master’s degree in cybersecurity, are able to identify and mitigate them. Here are some of the most common and problematic threats to organizations and their employees:
- Phishing attacks
Phishing has emerged as a perilous form of cyber assault that has gained prevalence in recent years. Cybercriminals craft counterfeit emails or messages that appear to be from trustworthy sources, such as reputable vendors or financial institutions.
The primary aim of phishing is to deceive the recipient into clicking on a link or downloading an attachment that is infused with malware or to furnish sensitive information, including login credentials. Once the attacker obtains access to this information, they can misuse it for malevolent purposes, such as pilfering funds or engaging in identity theft. Unfortunately, phishing attacks often triumph because they can be incredibly persuasive and hard to discern.
As per the 2022 Verizon Data Breach Investigations Report, phishing attacks are one of the most common types of breaches. This is a noteworthy fact that underscores the significance of taking preventive measures to safeguard an organization from these forms of attacks. One of the most effective ways for people to prevent phishing is by educating themselves and their staff about the telltale signs of such attacks.
This can include being vigilant of emails that request personal information or have pressing subject lines. It is also crucial to employ antivirus software and firewalls to thwart the downloading of malware onto a device. By adopting these measures, one can shield themselves and their organization from the catastrophic ramifications of a successful phishing attack.

The concept of malware entails the creation of software that has the potential to cause damage or disruption to computer systems, networks, and devices. Malware can infiltrate a system through various means, such as email attachments, internet downloads, or contaminated USB drives. Once installed, malware can be utilized to steal sensitive information, encrypt files as a ransom or take control of the infected device. Some of the most frequently occurring forms of malware include viruses, trojans, and spyware.
Viruses are capable of self-replicating and spreading to other devices, while trojans disguise themselves as genuine software and subsequently acquire control of the device, erase or pilfer data, or grant unauthorized access to cyber criminals. Spyware, on the other hand, can monitor a user’s activity without their awareness, enabling cybercriminals to collect valuable information such as login credentials and banking data. To prevent malware infections, it is imperative to use security software and exercise caution when opening email attachments, downloading software, or utilizing external drives.
- Ransomware
In recent times, the prevalence of ransomware attacks has escalated, posing a significant threat to both individuals and enterprises. Cybercriminals often utilize social engineering techniques such as phishing emails and contaminated downloads to spread ransomware to unsuspecting victims.
Once activated, the malicious software encrypts the victim’s files and denies access to their systems, prompting the payment of a ransom in exchange for the decryption key. In extreme cases, hackers may even resort to blackmail by threatening to publish sensitive information if the ransom is not paid, increasing the pressure on the victims.
For businesses, particularly those heavily reliant on their data, the impact of a ransomware attack can be catastrophic. They may suffer severe consequences such as financial losses, operational disruptions, and harm to their reputation. Furthermore, companies targeted by ransomware face a tough decision regarding whether to pay the ransom or not.
While payment could grant access to the decryption key, it also incentivizes future attacks and does not guarantee data retrieval. Consequently, it is crucial for businesses to adopt robust cybersecurity measures such as employee education, network monitoring, and data backups to mitigate the risk of ransomware attacks and reduce their impact if they occur.
- Insider threats
Organizations today face significant cybersecurity risks from insider threats, which can result from the malicious or unintentional actions of employees or contractors. These threats can take various forms, from intentional data theft or system sabotage to unintentional lapses such as falling for a phishing scam or leaving a device unattended. The consequences of insider threats can be severe, including financial losses, harm to reputation, and legal liabilities.
According to a 2020 report on insider threats by Cybersecurity Insiders, these attacks are becoming more prevalent, with 68% of organizations having experienced them in the past year. The challenge with insider threats is that they can be harder to detect and prevent than external attacks. They can come from various sources, including employees, contractors, and business partners, highlighting the importance of robust cybersecurity policies and procedures to mitigate the risks.
Organizations can reduce the likelihood of successful insider attacks by raising awareness among employees and implementing effective security measures. By taking proactive steps to protect their sensitive data and assets, organizations can prevent insider threats from causing significant harm.
The impact of cyber threats on businesses
Cybersecurity threats negatively impact businesses in multiple ways, including:
- Financial losses
One of the most significant impacts of cyber threats on businesses is financial losses. Cyber-attacks can result in lost revenue, increased expenses, and legal fees.
