Base64 Encoding Attack

Definitions

1. A tactic where payloads, commands, or malicious content are base64-encoded to bypass simplistic filters, hide intent in transit, or make analysis slightly harder. Base64 is encoding rather than encryption, so this is obfuscation, not secrecy.

   In plain English: Using base64-encoded content to hide or obfuscate malicious commands or payloads.

   Example: "The phishing kit delivered a base64 encoding attack chain that hid the PowerShell stage from basic keyword filters."
