2023-08-29 10:00:00 | Lutte contre les logiciels malveillants dans la chaîne d'approvisionnement industrielle Battling malware in the industrial supply chain (lien direct) |

Here\'s how organizations can eliminate content-based malware in ICS/OT supply chains. As the Industrial Internet of Things (IIoT) landscape expands, ICS and OT networks are more connected than ever to various enterprise systems and cloud services. This new level of connectivity, while offering benefits, also paves the way for targeted and supply chain attacks, making them easier to carry out and broadening their potential effects. A prominent example of supply chain vulnerability is the 2020 SolarWinds Orion breach. In this sophisticated attack: Two distinct types of malware, "Sunburst" and "Supernova," were secretly placed into an authorized software update. Over 17,000 organizations downloaded the update, and the malware managed to evade various security measures. Once activated, the malware connected to an Internet-based command and control (C2) server using what appeared to be a harmless HTTPS connection. The C2 traffic was cleverly hidden using steganography, making detection even more challenging. The threat actors then remotely controlled the malware through their C2, affecting up to 200 organizations. While this incident led to widespread IT infiltration, it did not directly affect OT systems. In contrast, other attacks have had direct impacts on OT. In 2014, a malware known as Havex was hidden in IT product downloads and used to breach IT/OT firewalls, gathering intelligence from OT networks. This demonstrated how a compromised IT product in the supply chain could lead to OT consequences. Similarly, in 2017, the NotPetya malware was concealed in a software update for a widely-used tax program in Ukraine. Though primarily affecting IT networks, the malware caused shutdowns in industrial operations, illustrating how a corrupted element in the supply chain can have far-reaching effects on both IT and OT systems. These real-world incidents emphasize the multifaceted nature of cybersecurity risks within interconnected ICS/OT systems. They serve as a prelude to a deeper exploration of specific challenges and vulnerabilities, including: Malware attacks on ICS/OT: Specific targeting of components can disrupt operations and cause physical damage. Third-party vulnerabilities: Integration of third-party systems within the supply chain can create exploitable weak points. Data integrity issues: Unauthorized data manipulation within ICS/OT systems can lead to faulty decision-making. Access control challenges: Proper identity and access management within complex environments are crucial. Compliance with best practices: Adherence to guidelines such as NIST\'s best practices is essential for resilience. Rising threats in manufacturing: Unique challenges include intellectual property theft and process disruptions. Traditional defenses are proving inadequate, and a multifaceted strategy, including technologies like Content Disarm and Reconstruction (CDR), is required to safeguard these vital systems. Supply chain defense: The power of content disarm and reconstruction Content Disarm and Reconstruction (CDR) is a cutting-edge technology. It operates on a simple, yet powerful premise based on the Zero Trust principle: all files could be malicious. What does CDR do? In the complex cybersecurity landscape, CDR stands as a unique solution, transforming the way we approach file safety. Sanitizes and rebuilds files: By treating every file as potentially harmful, CDR ensures they are safe for use while mainta | Malware Vulnerability Threat Industrial Cloud | NotPetya Wannacry Solardwinds | ★★ |
