Ransomware Defense Using the Wazuh Open Source Platform

"Ransomware is malicious software designed to block access to a computer system or encrypt data until a ransom is paid. This cyberattack is one of the most prevalent and damaging threats in the digital landscape, affecting individuals, businesses, and critical infrastructure worldwide. A ransomware attack typically begins when the malware infiltrates a system through various vectors such as phishing emails, malicious downloads, or exploiting software vulnerabilities. Once activated, the malware encrypts files using strong cryptographic algorithms, rendering them inaccessible to the legitimate owner."

"Modern ransomware variants have evolved beyond simple file encryption. Some employ double extortion tactics, where attackers encrypt data, exfiltrate sensitive information, and threaten to publish it publicly if the ransom is not paid. This puts pressure on victims, particularly organizations handling confidential customer data or proprietary business information. Understanding ransomware creation and distribution is essential for developing effective defense strategies. The ransomware lifecycle involves sophisticated development processes and diverse propagation methods that exploit technical vulnerabilities and human behavior."

Ransomware is malicious software that blocks access to systems or encrypts data until a ransom is paid. Attacks commonly begin when malware infiltrates systems via phishing emails, malicious downloads, or exploited software vulnerabilities. Once active, ransomware encrypts files using strong cryptography and attackers typically demand payment, often in cryptocurrency, for decryption keys. Modern variants use double extortion by stealing sensitive data and threatening public release, increasing pressure on organizations handling confidential or proprietary information. Ransomware development includes malware coding, Ransomware-as-a-Service models, and customization and testing. The ransomware lifecycle exploits technical vulnerabilities and human behavior.
