What Is Ransomware? Understanding the Threat
Ransomware is a type of malicious software that encrypts files on a victim’s device, rendering them inaccessible until a ransom is paid. Attackers typically demand payment in cryptocurrency to maintain anonymity. In 2025, ransomware has evolved beyond simple encryption—it now includes double extortion tactics , where attackers threaten to leak stolen data unless additional demands are met.
The rise of Ransomware-as-a-Service (RaaS) platforms has made it easier for even non-technical criminals to launch attacks. According to Sophos’ State of Ransomware 2024 , 66% of organizations were targeted by ransomware in the past year , highlighting the urgent need for robust defenses. Below is a breakdown of the most common ransomware attack vectors:
| Attack Vector | Description |
|---|---|
| Phishing Emails | Malicious links or attachments in emails. |
| Exploiting Vulnerabilities | Unpatched software vulnerabilities used as entry points. |
| Remote Desktop Protocol (RDP) | Unauthorized access to systems via weak or stolen credentials. |
| Supply Chain Attacks | Compromising third-party vendors to infiltrate networks. |
