    "description": "Base64 is a simple encoding scheme that is often used by malware to represent binary data in an ASCII string. This allows the malware to encode and transmit binary data, such as a payload or network traffic, in a way that is more compact and easier to transmit over text-based communication channels. \r\n\r\nBase64 uses a 64-character alphabet to encode the data, which includes the upper and lower case letters, the digits 0-9, and the symbols \"+\" and \"/\". The encoded data is typically padded with the character \"=\" to ensure that it has a length that is a multiple of 4. The encoded data can then be decoded using the same 64-character alphabet to recover the original binary data. This makes Base64 a useful tool for malware to conceal their payloads and communicate with their command and control (C2) servers.",
