System data exfiltration refers to the unauthorized transfer or removal of data from a computer system or network. This malicious activity typically involves cybercriminals stealing sensitive information, such as private keys, financial records, or personal data, and transmitting it to an external, controlled location. Exfiltration can occur through various channels, including network protocols, removable media, or encrypted tunnels. It represents a significant breach of data confidentiality.
