Despite the allure of "free unlocking," using an 18-year-old RAR archive on modern systems is fraught with issues:
Siemens SIMATIC S7 PLCs (S7-200, S7-300) often use MMC or similar memory modules to store user programs, data blocks, and configuration. Sometimes MMC contents are archived into RAR files for transport or backup. Password protection may be applied to protect projects and block contents. This post explains safe, legal approaches to recover access, extract archived RAR files, and restore PLC program access when you have proper authorization.
The specific string 2006 09 11 in the keyword is not a random number. It strongly points to a release date or a file date stamp inside a specific RAR archive circulating on Chinese and Russian automation forums (e.g., PLCjs, Chinaba, or PLCforum.uz).
This particular RAR file, often named something like S7_200_300_MMC_Unlock_2006.rar, typically contains:
Why September 11, 2006? This date roughly aligns with the release of STEP 7 V5.4 + SP3 and a known change in Siemens' MMC file system structure. Early MMC cards (pre-2006) were easier to unlock because the password was stored in plaintext or weak XOR. After 2006, Siemens moved to a slightly more robust hashing algorithm. The "2006-09-11" archive likely provided a transitional hack that worked on both older S7-300 MMCs and the S7-200's EEPROM.
Many .rar files from 2006-2010 contain packed executables that modern antivirus flags as Trojan.PLC or Generic.Malware. Some are false positives (due to kernel-level USB access), but others are genuine keyloggers or ransomware. Always sandbox in a VM.
