  "bluf": "MITRE ATT&CK T1027.001 (Binary Padding) is an Enterprise Defense Evasion sub-technique of T1027 (Obfuscated Files or Information). Adversaries may use binary padding to add junk data and change the on-disk representation of malware. This can be done without affecting the functionality or behavior of a binary, but can increase the size of the binary beyond what some security tools are capable of handling due to file size limitations. Binary padding effectively changes the checksum of the file and can also be used to avoid hash-based blocklists and static anti-virus signatures. Affected platforms: Linux, macOS, Windows. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-03, CM-02, CM-06, CM-07, SI-02, SI-03, SI-04, SI-07.",
