Tools that claim to "find" passwords for S7 PLCs often operate by analyzing a memory dump or a backup file.

Programmable Logic Controllers (PLCs) are fundamental components of Industrial Control Systems (ICS). This paper examines the security architecture of the Siemens S7-300 and S7-400 series, with a specific focus on the S7Comm protocol. It analyzes the implementation of access protection mechanisms, discusses known vulnerabilities regarding authentication and key management in legacy firmware, and outlines a comprehensive defense-in-depth strategy for mitigating unauthorized access risks in critical infrastructure environments. 4.

Connect via STEP 7 or Siemens Automation Tool. Note the firmware version. If it ends with "V3.14", you have KeyS7 v314.

When industrial engineers lose the password to a Siemens S7 PLC, they often search for tools or methods associated with the string s7-keys7-v314. This refers to an older, now-deprecated protection mechanism used in Siemens STEP 7 Classic (TIA Portal’s predecessor). The "v314" indicates a variant of the KeyS7 password hashing or encryption algorithm. Unlike modern Siemens PLCs that use certificate-based or 20-character alphanumeric passwords, the S7-300/400 family (firmware before 3.0) used a vulnerable Know-how Protection method that can be recovered—under strict legitimate conditions. 3.
