• Siemens had a near-monopoly on industrial PLCs in Europe and Asia.
• The S7-300 MMC was relatively new (replacing the older EPROM cards).
• Password protection for S7-200 used a weak XOR-based obfuscation, not strong cryptography. Researchers (e.g., Dmitry E. in 2007–2008) published that the 8-character password could be recovered from a memory dump.
• For S7-300, the password was stored on the MMC in encrypted form, but early MMC firmware (pre-2009) had flaws. Tools like "S7 MMC Password Unlocker" and "MMC Reader" (often shared as .rar files) claimed to bypass or reset the password by reading raw sectors.
