The FBI says hackers are attempting to infect companies with the Kwampirs malware, a remote access trojan (RAT).
"Software supply chain companies are believed to be targeted in order to gain access to the victim's strategic partners and/or customers, including entities supporting Industrial Control Systems (ICS) for global energy generation, transmission, and distribution," the FBI said in a private industry notification sent out last week.
Besides attacks against supply chain software providers, the FBI said the same malware was also deployed in attacks against companies in the healthcare, energy, and financial sectors.
The alert did not identify the targeted software providers, nor any other victims.
Instead, the FBI shared IOCs (indicators of compromise) and YARA rules so organizations can scan internal networks for signs of the Kwampirs RAT used in the recent attacks.
