Several advanced persistent threat (APT) actors have created custom-made tools designed to breach IT equipment used in critical infrastructure facilities, according to a new advisory from multiple US agencies. 

In an alert released on Wednesday, the Department of Energy (DOE), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Federal Bureau of Investigation (FBI) warned critical infrastructure operators of potential attacks targeting multiple industrial control systems (ICS) and supervisory control and data acquisition (SCADA) devices. 

The alert says the tools used in the attacks were designed specifically for Schneider Electric programmable logic controllers (PLCs), OMRON Sysmac NEX PLCs, and Open Platform Communications Unified Architecture (OPC UA) servers.
