Data exfiltration refers to the unauthorized transfer of sensitive data from an organization’s network. This sophisticated threat can be used for various malicious purposes, including intellectual property theft, financial gain, and espionage. Attackers target sensitive data such as customer records, employee information, or trade secrets, and transfer it out of the secure environment without detection. The consequences of data exfiltration can be severe, impacting an organization’s operations, reputation, and financial stability.
What are the signs of data exfiltration?
Following are the signs of data exfiltration:
- Unusual network activities
- Odd access patterns
- Use of unauthorized or external devices on secure systems
- Regularly sending big chunks of data through email out of an organization
- Having unauthorized remote access tools
- Modifying access permissions
What is the difference between data breach and data exfiltration?
A data breach happens when one gets unauthorized access to your data. This could be through hacking, phishing, or finding vulnerabilities in the system. The data obtained during a breach may or may not be deleted from the network. A breach means that the area where your data is kept safe has been compromised.
On the other hand, data exfiltration is a special kind of data breach where one who breaks in not only gets access but also takes the data out of the safe place where it was kept. This is like sneaking out important information from a protected network without being caught.
