What is Ransomware Glossary?
This section of our Ransomware Glossary breaks down fundamental terms you'll encounter when learning about or dealing with ransomware. We've compiled a list of key vocabulary to build your understanding of malware terms and how these threats operate. Each term is explained simply for clarity.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Ransomware | Noun | Malicious software that encrypts a victim's files, demanding a payment (ransom) for the decryption key. | The hospital's network was crippled by ransomware, locking access to patient records. |
| Encryption | Noun | The process of converting data into a code to prevent unauthorized access, making it unreadable without a key. | Encryption is a vital security measure, but malicious actors use it in ransomware to hold data hostage. |
| Decryption Key | Noun Phrase | A secret piece of information (like a password) used to unlock and restore encrypted data to its original, readable form. | Victims of ransomware hope to receive the decryption key after paying, though it's not always guaranteed. |
| Malware | Noun | Short for "malicious software"; any software intentionally designed to cause damage or gain unauthorized access. | Malware encompasses viruses, worms, trojans, spyware, and ransomware, all posing threats to digital security. |
| Phishing | Noun | A fraudulent attempt to obtain sensitive information (like usernames, passwords) by disguising as a trustworthy entity. | Many ransomware attacks begin with a phishing email that tricks an employee into downloading a malicious attachment. |
| Exploit | Noun / Verb | (Noun) A piece of code that takes advantage of a software vulnerability. (Verb) To take advantage of such a flaw. | Cybercriminals developed an exploit for the unpatched software to deploy their ransomware. |
| Vulnerability | Noun | A weakness in a computer system, software, or network that can be exploited by a threat actor. | Regular software updates are crucial to patch vulnerabilities that ransomware attackers might target. |
| Payload | Noun | The component of malware that performs the actual malicious action, like encrypting files in a ransomware attack. | Once the malware infiltrated the system, its payload began encrypting all document files. |
| Bitcoin | Noun | A decentralized digital currency, often demanded for ransom payments due to its perceived anonymity. | The attackers demanded the ransom be paid in Bitcoin to a specific digital wallet address. |
| Cybersecurity | Noun | The practice and field dedicated to protecting computer systems, networks, and data from theft, damage, or unauthorized access. | Investing in robust cybersecurity measures can help prevent ransomware incidents and protect sensitive information. |
| Backup | Noun | A copy of data stored separately, allowing for restoration in case of data loss, system failure, or a ransomware attack. | Having a recent backup allowed the company to restore its files without paying the ransom. |
| Botnet | Noun | A network of compromised computers (bots) controlled by an attacker to perform coordinated malicious activities. | Ransomware can sometimes be distributed through a botnet, infecting many computers simultaneously. |
| Zero-day | Adjective/Noun | A software vulnerability unknown to those who should be interested in mitigating it, including the software vendor. | A zero-day exploit is particularly dangerous because no patch exists when it's first used in attacks. |
| Threat Actor | Noun Phrase | An individual or group responsible for creating or deploying a threat, such as a ransomware attack. | Cybersecurity professionals work to identify the threat actor behind major ransomware campaigns. |
| Data Breach | Noun Phrase | An incident where sensitive, protected, or confidential information is copied, transmitted, viewed, or stolen. | A data breach caused by ransomware can expose personal customer information, leading to severe consequences. |
