Potential Base64 Decoded From Images
Detects the use of 'tail' to extract bytes at an offset from an image file (e.g., JPEG, PNG) and then pipe the output to 'base64 --decode' to create a new file with the decoded content. This technique is often used by adversaries to deobfuscate or extract hidden payloads from seemingly innocuous image files, typically executed as a bash one-liner.
