In today’s digital age, ransomware attacks have become a prevalent threat to businesses of all sizes. Small and medium-sized businesses (SMBs) are particularly vulnerable to these cyber threats. This article explores the nature of ransomware, its impact on SMBs, and actionable strategies for prevention and response.

Understanding Ransomware

What Is Ransomware?

Ransomware is a type of malicious software designed to block access to a computer system or data until a ransom is paid. Typically, ransomware encrypts the victim’s files, making them inaccessible without a decryption key, which is held hostage by the attacker. There are various types of ransomware, including crypto-ransomware, which encrypts files, and locker ransomware, which locks users out of their systems.

How Ransomware Works

Infection: Ransomware often enters a system through phishing emails, malicious downloads, or exploiting vulnerabilities in software. Once executed, it begins to encrypt files or lock the system.
Ransom Demand: After encryption, the attacker demands a ransom, usually in cryptocurrency, to provide the decryption key. The ransom note typically includes instructions for payment and a deadline.
Payment and Decryption: Paying the ransom does not guarantee that the attacker will decrypt the files. In many cases, businesses have paid only to find that the decryption key is ineffective or that they are targeted again.
