RansomwareTrojaner

RansomwareTrojaner is a term used in cybersecurity to describe a class of malicious software that combines Trojan-like delivery with ransomware payloads. The name, often found in German-language sources, refers to threats that reach a system via a trojan component and subsequently deploy ransomware to encrypt data or restrict access, followed by a demand for payment.

In practice, these threats are typically delivered as trojanized programs, phishing attachments, or malicious macros within documents. Once executed, the trojan installs a ransomware payload, may attempt to disable security software, and then encrypts files or locks the operating system. Some campaigns also exfiltrate data and threaten public disclosure as a form of double extortion. Ransom notes commonly demand payment in cryptocurrency and specify deadlines, with varying levels of technical sophistication in the ransom negotiation workflow.

Typical characteristics include the use of loaders or droppers to deploy the main ransomware, persistence mechanisms to survive user logouts, and, in some cases, lateral movement to affect multiple devices within a network. Variants differ in encryption methods, file targeting, and ransom note presentation, but the core goal remains the same: monetize unauthorized access by denying victims access to their data.

Impact of RansomwareTrojaner campaigns ranges from operational downtime and data loss to financial costs and reputational damage for organizations. Mitigation focuses on prevention, rapid detection, and robust recovery procedures. Best practices include regular offline backups, timely patching, principle of least privilege, network segmentation, endpoint protection, email and macro controls, user training, and a tested incident response plan. In case of infection, isolate affected systems, restore from clean backups, and consult authorities; paying ransom is generally discouraged.
