Ransomware attacks have been on the rise globally, and Kenya has not been spared. The recent attacks on the Kenya Airports Authority (KAA) and Naivas Supermarket have highlighted the need for individuals and organizations to take cybersecurity seriously.
What is Ransomware?
Ransomware is a type of malware that encrypts a victim’s files or system and demands a ransom payment in exchange for the decryption key. Ransomware attacks can target individuals or organizations, and they can be devastating as they can cause loss of data, financial losses, and reputational damage.
How does Ransomware Work?
Ransomware attacks can occur through various means, including phishing emails, malicious attachments, or exploiting vulnerabilities in software or systems. Once the ransomware gains access to a system, it begins to encrypt files, making them inaccessible to the user. The attackers then demand a ransom payment, usually in cryptocurrency, in exchange for the decryption key. The ransom amount can vary depending on the type of ransomware and the targeted victim.
Examples of Ransomware Attacks in Kenya
The recent ransomware attacks on the Kenya Airports Authority and Naivas Supermarket are examples of how devastating these attacks can be. The KAA attack The attack did not have a significant financial or operational impact, and KAA claims that no sensitive data was stolen. However, the attackers released 514 GB of data, including procurement plans, physical plans, site surveys, invoices, and receipts, on the internet. The Naivas attack, on the other hand, exposed private information including invoices, agreements, and customer data to possible manipulation by unknown actors.
How to Protect Yourself from Ransomware Attacks

- Keep your software and systems up to date: Ensure that you install updates and patches for your operating system, software, and applications regularly.
