Trend Micro research, conducted by Proof of Concept (PoC), reveals the possibility of multiple attacks on connected systems<\/em><\/p>\n THE\u00a0Trend Micro<\/strong>, a world leader in cybersecurity solutions, conducted in-depth research highlighting the\u00a0new threats to 4G\/5G campus networks, many of which capitalize on the difficulty organizations have in remediating critical Operating Technology (OT) environments.<\/strong>\u00a0The report details various attack scenarios and possible mitigations using a test environment designed to mimic an intelligent factory network.<\/p>\n \u201cManufacturers are at the forefront of deploying the IIoT (Industrial Internet of Things), and are gearing up to harness the power of 5G connectivity everywhere to drive greater speed, security and efficiency. But with the new technology also come new threats to the challenges assumed\u201d, highlights Yohei Ishihara, Security Evangelist at Trend Micro. \u201cAs the report warns, many are stuck in a dead end \u2014 unable to afford the downtime necessary to fix critical system vulnerabilities that could otherwise be exploited. Fortunately, our extensive research also highlights multiple mitigations and best practices to protect smart factories today and tomorrow.\u201d<\/p>\n The report identifies several key entry points for attackers to compromise a core 4G\/5G network:<\/p>\n \u2022\u00a0Servers that host core network services:<\/strong>\u00a0targeting vulnerabilities and weak passwords on these standard COTS x86 servers; Once the attacker enters the core network from any of these entry points, it will move sideways in an attempt to intercept and alter the data packets. By attacking intelligent factory industrial control systems, such as the one simulated at the test site, attackers can steal sensitive data, sabotage production, or demand rescue from companies for information hijacking.<\/u><\/u><\/p>\n
\n\u2022\u00a0VMs or containers:<\/strong>\u00a0these can also be exposed if the\u00a0patches<\/em>\u00a0not applied promptly;
\n\u2022Network infrastructure:<\/strong>\u00a0devices are often forgotten during cycles of\u00a0patch<\/em>;
\n\u2022\u00a0Base stations:<\/strong>\u00a0also contain\u00a0firmware<\/em>\u00a0(embedded software) that needs to be updated from time to time.<\/u><\/u><\/p>\n
