This class discusses the basic concepts of programming Siemens PLCs. Linear and modular programming are both discussed, as well as different types of Siemens PLC engineering software and PLC program ...

Siemens decided at the time instead to rely on fixed cryptographic keys to secure programming and communications between its PLCs and the TIA portal. However, with advances in technology ...

Security researchers have found a way to extract a global encryption key that was hardcoded in the CPUs of several Siemens programmable logic controller (PLC) product lines, allowing them to ...

Siemens S7 programmable logic controllers, the same PLC family exploited by the Stuxnet malware, are in the crosshairs of a password-cracking tool that is capable of stealing credentials from ...

However, Siemens in March did issue a security advisory (PDF) warning flaws “could possibly allow an attacker to circumvent user program block protections” in its SIMATIC S7-1200 PLCs.

They deployed a new remote code execution (RCE) technique targeting the central processing units (CPUs) of SIMATIC S7-1200 and S7-1500 PLCs, for which they used a vulnerability uncovered in previous ...
