Exfiltration of data is never a good thing. Whether the data is exfiltrated from servers, data centers or websites, the premise remains the same - it’s a security issue that takes a lot of time and effort to recover from. Data exfiltration, in general, is the act of unauthorized moving of information from inside a company to outside of it.

Once you suspect that your business may have been a victim of a data exfiltration attack, you should:

  • Make sure you have proper backups.
  • Make sure that your backups can be promptly and easily recovered.
  • Run employee awareness tests across your whole organization and make sure the results are satisfying (i.e make sure that a certain percentage of your organization can answer certain awareness-related questions etc.)
  • Notify all related people - who has the attacker sent emails to? Who responded? When? Why? How? etc.
  •  Take action to prevent such issues from happening in the future - make sure your infrastructure is protected by anti-spam filters, firewalls etc. and you have security audits going on at least once a year.

Making sure that you have backups and that they can be recovered can also be helpful in this scenario - if your sensitive business data has been compromised or exfiltrated, you might want to recover your data backups locally and observe any inconsistencies in the data that has been recovered before moving on to security measures.
