Sophos, a leading cybersecurity firm, has unveiled alarming findings in their recent survey titled "The State of Ransomware in Manufacturing and Production 2023." The report highlights that over two-thirds (68 percent) of ransomware attacks targeting the manufacturing sector successfully encrypt crucial data. Moreover, IBM's research confirms that manufacturing is the most heavily targeted industry worldwide, with ransomware accounting for a staggering 23 percent of attacks in 2021.
As the persistent ransomware threat persists, manufacturers must explore effective strategies to eliminate these debilitating assaults. With manufacturing emerging as the primary target for one in five ransomware attacks, the sector's profitability (reaching $44.5 trillion in 2022) combined with its vulnerability due to highly digitized infrastructure provides cybercriminals with ample exploitable opportunities.
John Shier, Field Chief Technical Officer at Sophos, emphasizes the significance of employing backup systems as the primary recovery mechanism, facilitating faster restoration. While the temptation to pay ransoms may arise, the survey's response data demonstrates that doing so doubles the cost of recovery. To mitigate the substantial financial burden resulting from ransomware attacks, manufacturers must prioritize early detection and response capabilities.
Surprisingly, the report reveals that despite the increasing adoption of backup solutions, manufacturing and production organizations have experienced prolonged recovery times. In 2022, only 67 percent of surveyed manufacturers recover within a week, while 33 percent take longer. In contrast, the previous year witnessed a higher recovery rate, with 55 percent of manufacturing entities regaining control within a week.
The prolonged recovery duration within the manufacturing sector represents a worrisome trend. Sophos' Active Adversary report, based on incident response cases, consistently identifies manufacturing as the industry requiring the most assistance in recovering from attacks.
This protracted recovery process adversely impacts IT teams, with 69 percent reporting excessive time spent on handling security incidents, leading to a diversion of resources from other critical projects. To address these challenges, Sophos experts advocate the implementation of best practices across the manufacturing industry and other sectors. Strengthening the defensive shield against prevalent attack vectors necessitates the deployment of robust security tools such as endpoint protection fortified with anti-exploit capabilities to preempt vulnerability exploitation.
Additionally, implementing Zero Trust Network Access (ZTNA) solutions helps thwart the misuse of compromised credentials. Adaptive technologies that automatically respond to attacks, disrupt adversaries, and provide ample response time are paramount. To ensure comprehensive protection, organizations must adopt round-the-clock threat detection, investigation, and response mechanisms, either through in-house teams or specialist Managed Detection and Response (MDR) providers.
Manufacturers and other potential targets must optimize their preparedness against ransomware attacks. This includes regular data backups, practicing data restoration from these backups, maintaining up-to-date incident response plans, and upholding strong security hygiene by promptly applying patches and regularly reviewing security appliance configurations. The stakes are high for targeted manufacturing companies, as the consequences extend beyond financial losses to include halted production, supply chain disruptions, and severe reputational damage.
