When ransomware attacks were gaining momentum and lot adoption started to expand, security experts already began to look at the potential risks of ransomware attacks when they involve the loT. Disruption is also the main goal for ransomware attacks in other industries, which likely also rely to some extent on loT devices and systems. In the Trend Micro midyear roundup, we reported how manufacturing, healthcare, and food and beverage were among the top five industries that saw the most ransomware activity. The healthcare industry saw attacks from the likes of Ryuk and Conti ransomware families, which added pressure to an already strained healthcare system amidst the pandemic. It is difficult to determine if these recent attacks had a direct impact on medical devices, but ransomware has been known to infect medical devices before. Connected medical devices, while incredibly useful today, can also act as entry points for attacks flaws that make them susceptible to malware infection. loT and ransomware are worth reexamining now that a different breed of ransomware families are targeting organizations and loT use has become widespread in the industrial sector. if not properly managed. Medical devices also carry vulnerabilities and loT and ransomware attacks Ransomware attacks hinge on being timely, critical, and irreversible. The involvement of loT in ransomware campaigns can amplify the impact of attacks because of cascading consequences especially in the case of critical infrastructure. In addition, loT devices widen the attack surface through which ransomware can be deployed. These are conditions that can exacerbate disruptions. Aside from the healthcare industry, the food production industry has also adopted loT tools and systems to optimize production. According to an FBI advisory, ransomware attacks are targeting the food and agriculture sector to exfiltrate and encrypt data. They note how the sector is becoming increasingly more reliant on lot processes, expanding the attack surface. Some of these attacks did not only cost the victims, but also affected the supply chain, driving prices up for consumers. Ransomware attacks pose a threat to OT systems Routers and other loT devices as entry points for malware The loT can significantly redefine the attack surface an organization would need to secure. This concern also includes every-day loT devices such as smart appliances and routers. Once set up, some loT devices, specifically routers, are often forgotten in the Ransomware operators like DarkSide have set their sights on critical infrastructures or high-profile targets.

Botnet malware, a well-known problem for loT devices, can also be used to distribute other malware In our research on loT botnets, we found that it is still possible for routers to remain infected with a batnet that has been defunct for two years, highlighting how seemingly simple devices can act as a doorway for critical attacks.
