Impost3r

Impost3r is a C language-based tool designed for stealing various types of passwords on Linux systems, specifically targeting sudo, su, and ssh credentials. It operates by manipulating user environment files to intercept password entries without alerting the user, automatically erasing traces post-use, and can transmit the captured data via DNS protocol. Noteworthy features include stealth operation, automated cleanup of traces, and adaptable configurations for local storage or network transmission of stolen credentials.
