The U.S. Department of Health and Human Services (HHS) Health Sector Cybersecurity Coordination Center (HC3) released a threat briefing on “Living off the Land.” This term has two meanings. In the physical world, it refers to survival using natural resources. In cybersecurity, it describes a type of attack (known as LOLbins or LOTL) where attackers exploit legitimate software and system functions to carry out malicious activities.
These attacks are increasingly common due to their stealthy nature, allowing threat actors to bypass traditional security measures and disguise their actions as normal processes. This poses a significant risk to healthcare systems that rely on a variety of trusted technologies.
Attackers often utilize existing tools embedded in operating systems, complicating detection efforts for legacy security systems. Healthcare organizations face unique challenges, including complex, interconnected systems, limited budgets that lead to outdated software, and increased vulnerabilities from the digitization of medical devices. Together, these factors create an environment particularly susceptible to cybercriminal exploitation, highlighting the urgent need for enhanced cybersecurity measures and awareness within the healthcare sector.
