Exfiltrating

Exfiltrating, in the context of data security and espionage, refers to the unauthorized removal of sensitive information or data from a computer system or network. It involves surreptitiously extracting and transferring data, typically to an external location or unauthorized recipient. The process often involves bypassing security measures and concealing the activity to avoid detection. The primary goal of exfiltration is usually to compromise confidential information for malicious purposes, such as espionage, financial gain, or reputational damage. Techniques include exploiting vulnerabilities, using malware, or social engineering.
