ShellSweep Tool Detects Potential Webshell Files
/ 1 min read
🔍 ShellSweep tool detects potential webshell files using entropy analysis. ShellSweep is a versatile tool developed in PowerShell, Python, and Lua, designed to identify potential webshell files within specified directories by calculating the entropy of file contents. It focuses on file types commonly associated with webshells, such as .php and .jsp, and allows users to exclude certain directories and file hashes from scans. High entropy values, indicative of randomness often found in obfuscated or encrypted code, serve as a key indicator for potential threats. The tool includes functions like Get-Entropy and ShellScan, which help analyze and compare entropy values across multiple files, enhancing the detection of malicious scripts while acknowledging that high entropy alone is not a definitive sign of maliciousness.
