#T1560 Archive Collected Data

Technique

  • Tactics: Collection
  • Description:

    An adversary may compress and/or encrypt data that is collected prior to exfiltration. Compressing the data can help to obfuscate the collected data and minimize the amount of data sent over the network.(Citation: DOJ GRU Indictment Jul 2018) Encryption can be used to hide information that is being exfiltrated from detection or make exfiltration less conspicuous upon inspection by a defender.

    Both compression and encryption are done prior to exfiltration, and can be performed using a utility, 3rd party library, or custom method.
