Techopedia explains Data Exfiltration
Data exfiltration is primarily a security breach that occurs when an individual’s or organization's data is illegally copied. Generally, data exfiltrations are targeted attacks where the hacker’s/cracker’s primary intent is to find and copy specific data from the target machine. The hackers/crackers gain access to the target machine through a remote application or by directly installing a portable media device. Statistically, these breaches mainly occurred on systems with a vendor-set default password or very common/easy passwords.
