PLC Maker Micro-Comm Suffers Ransomware Attack
Olathe, Kansas-based maker of programmable logic controllers (PLCs), Micro-Comm, suffered a ransomware attack in late July where the attacker claimed to steal 644 GB of data.
Micro-Comm supplies control technology to water and wastewater utilities and the ransomware group Barracuda said it stole 644 GB of data from 850,000 files. To that end, Micro-Comm said sensitive user credentials and remote-access information did not end up compromised.
In this attack, the FBI said it is investigating the ransomware attack of the supplier of PLCs and related technology used by public water and wastewater facilities. The exposed material reportedly includes government customer names and system diagrams, information that could assist later attacks even where operating credentials did not end up compromised.
