Software Packing with Nimcrypt2

T1027.002 · MITRE ATT&CK

Software packing compresses or encrypts an executable to conceal its code; many packers restore executable code in memory at runtime. This record covers the packing capability documented by Nimcrypt2 for .NET, PE, and raw shellcode inputs. The available sources do not establish that it specifically places payloads in non-standard PE sections, that a particular output evades a named security product, or that packing guarantees detection bypass.
