Across the industrial control systems industry, researchers have identified systemic weaknesses in PLC authentication mechanisms. A 2022 study of proprietary authentication protocols from leading ICS vendors including Schneider Electric, Allen-Bradley, AutomationDirect, Siemens, and others revealed serious design issues, including lack of cryptographic nonces, small-sized encryption keys, and insecure hashing algorithms.

Fatek Automation’s FBs and FBe series Programmable Logic Controllers (PLCs) are widely known for their compact design, robust performance, and cost-effectiveness. As with any industrial automation component, these controllers often utilize password protection to safeguard proprietary intellectual property—such as custom logic, ladder diagrams, and operating parameters—stored within the PLC’s memory.

Researchers from Dragos found that these tools often drop the Sality malware, which turns the engineering workstation into a botnet member for cryptomining and password cracking.
If the original code is not required and the goal is simply to reuse the PLC, you can often clear the memory, which clears the password. In WinProLadder, this involves using the "Clear All" function while connected to the PLC, or following specific hardware procedures outlined in the Fatek PLC manual. 3.

In the world of industrial automation, Programmable Logic Controllers (PLCs) serve as the brains of manufacturing lines, energy systems, and critical infrastructure. Fatek Automation, a well-known Taiwanese manufacturer, produces widely used PLCs such as the FBs, FBe, B1, and B1z series. Like most industrial controllers, Fatek PLCs incorporate password protection to safeguard proprietary control logic and prevent unauthorized modifications.
Because older Fatek PLCs do not enforce anti-hammering rules (such as locking the PLC after three incorrect attempts), automated scripts can bombard the serial port with thousands of password combinations per minute until the correct one is found. If the original code is not required and
Older generations of Fatek FBs series PLCs utilized simple numeric or alphanumeric passwords (typically ranging from 4 to 6 characters). These legacy systems lacked advanced cryptographic mechanisms. Instead, they relied on basic security through obscurity, storing or transmitting passwords in easily interceptable formats. 2. Communication Protocol Flaws

Unauthorized tools can inadvertently overwrite critical memory sectors, permanently bricking the Fatek CPU.
Implement strict Access Control Lists (ACLs) to ensure only authorized engineering workstations can communicate with the PLC IP addresses. Physical Security
