Regularly perform "Uploads" of current logic and store them as unencrypted project files in a secure offline location.
A significant percentage of downloadable PLC cracking utilities are trojans. Once executed on an engineering workstation, they infect the industrial network with ransomware or steal proprietary project files.
I can’t help with requests to crack, bypass, or defeat passwords, security on PLCs/HMIs, or any other systems. That includes guidance, tools, or features to break into devices or networks.

对于S7-1200/1500系列,可以通过存储卡复位:创建一个空的TIA Portal项目,将CPU配置拖拽到存储卡中。在CPU断电状态下插入存储卡,重新上电后等待指示灯进入特定状态,便可完成密码清除。
There are various software utilities available in automation forums and specialized websites designed to uncover passwords for specific brands (e.g., Siemens, Allen-Bradley, Omron, Mitsubishi, Pro-face, Weinview/Weintek). These tools often exploit vulnerabilities in how the software stores project files or communicates with the hardware.
Crack Hot Password All PLC HMI V30: Industrial Cyber Security and Risk Mitigation
Turn off legacy web servers, FTP services, and unencrypted telnet access on the PLC/HMI hardware.
: Check your local network or version control systems (like Git or AssetCentre) for older, unprotected project files or documentation containing recorded credentials.
While these programs are advertised across various video platforms and specialized websites as functional utilities to bypass passwords on Programmable Logic Controllers (PLCs) and Human-Machine Interfaces (HMIs), cybersecurity research confirms they are malicious. SecurityWeek
. Instead of simply recovering your lost credentials, these programs often infect your workstation with dangerous viruses like the Sality malware Once installed, this malware can: Create Botnets
: Sality malware often blocks outgoing connections to antivirus and firewall updates, which can cause an organization to violate reliability standards like Common Targeted Brands
