This means end users had no reasonable opportunity to detect or prevent infection, as the threat originated from a trusted hardware supplier. The malware silently converted devices into residential proxy servers and ad fraud tools, exploiting the implicit trust organizations and consumers place in OEM firmware. This matters because IoT and set-top box ecosystems often lack robust firmware validation, creating a silent attack surface at massive scale. Google's delayed discovery of the firmware-level compromise underscores how insufficient supply chain vetting can enable threats to persist across millions of devices globally.","**Immediate actions:**\n- Audit all third-party hardware suppliers and their firmware signing processes to detect unauthorized or malicious code embedded at manufacture.\n- Remove or quarantine devices sourced from Videostrong or similarly implicated vendors and perform forensic analysis before reconnecting any replacements.\n\n**Long-term improvements:**\n- Establish a mandatory firmware review and cryptographic signing verification process before any OEM device is approved for distribution or use.\n- Implement a formal supplier risk management program that includes contractual security obligations, independent code audits, and regular reassessment of all hardware vendors.\n- Maintain a comprehensive inventory of all IoT and embedded devices on the network to enable rapid response when a supply chain compromise is identified.\n\n**Detection measures:**\n- Deploy network monitoring to detect anomalous outbound traffic patterns (e.g., proxy relay behavior or ad fraud callbacks) from IoT and set-top box devices.\n- Integrate threat intelligence feeds to receive early warnings about compromised firmware versions and correlate them against deployed device inventories.",[12,13,14,15,16,17,18],"CIS Control 15: Service Provider Management","NIST SP 800-53 SI-2: Flaw Remediation","ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities","OWASP A06:2021 Vulnerable and Outdated Components","NIS2 Article 21(2)(b)","MITRE ATT&CK T1195: Supply Chain Compromise","CIS Control 13: Network Monitoring and Defense",{"NIS2 Article 21(2)(b)":20,"NIST SP 800-53 SI-2: Flaw Remediation":21,"CIS Control 15: Service Provider Management":22,"MITRE ATT&CK T1195: Supply Chain Compromise":23,"CIS Control 13: Network Monitoring and Defense":24,"OWASP A06:2021 Vulnerable and Outdated Components":25,"ISO\u002FIEC 27001:2022 A.8.8: Management of technical vulnerabilities":26},"NIS2 requires covered entities to implement supply chain security measures including assessment of supplier security practices; mandating such reviews of hardware OEMs like Videostrong would have surfaced the deliberate malware inclusion before widespread distribution.","Formal flaw remediation processes applied to firmware — including verification that OEM-supplied code is free of malicious modifications — would have mandated review cycles that could have surfaced the embedded malware before mass deployment.","Videostrong, as a hardware supplier and OEM, should have been subject to rigorous third-party vetting; this control requires organizations to assess and monitor the security practices of service and product providers to prevent exactly this kind of embedded supply chain threat.","The XCPE botnet is a textbook example of T1195, where an adversary (in this case, the manufacturer itself) implants malicious functionality into hardware or firmware prior to customer delivery, bypassing all endpoint defenses.","Continuous monitoring of network traffic originating from IoT devices would have detected the anomalous proxy-relay and ad fraud traffic patterns generated by XCPE-infected set-top boxes, enabling earlier discovery and containment of the botnet.","Firmware that ships with pre-installed malware represents a compromised component in the software supply chain; OWASP A06 highlights the risk of using components from untrusted or insufficiently vetted sources, directly applicable to OEM firmware review failures.","This control requires organizations to identify and address technical vulnerabilities in a timely manner, which extends to firmware-level threats; a structured vulnerability management process covering IoT firmware would have flagged the malicious Videostrong code.","published","2026-11-03T11:22:14.110353+00:00","2026-11-03T11:22:14.085+00:00",{"id":7,"url":31,"slug":32,"title":33},"https:\u002F\u002Fsecurityaffairs.com\u002F202323\u002Fmalware\u002Finside-xcpe-the-botnet-that-turned-1-3m-set-top-boxes-into-proxy-servers.html","inside-xcpe-the-botnet-that-turned-1-3m-set-top-boxes-into-proxy-servers-89baec","Inside XCPE, the botnet that turned 1.3M set-top boxes into proxy servers",[35,41],{"id":36,"name":37,"slug":38,"description":39,"color":40},"859cf0ad-a7e9-42bb-a75d-bac6511fa5d5","Configuration Management","configuration-management","Misconfigs, default credentials, exposed services","#eab308",{"id":42,"name":43,"slug":44,"description":45,"color":46},"f0c2a0af-58aa-4128-87c9-6acd30f2dc48","Supply Chain","supply-chain","Third-party risk, compromised dependencies","#8b5cf6",[],[49,53,57],{"slug":50,"name":51,"problem":52},"vulnerability-management","Vulnerability scanning and prioritisation","You know which systems are vulnerable, and which ones to fix first.",{"slug":54,"name":55,"problem":56},"asset-inventory","Cyber asset inventory","You cannot patch, monitor or protect the devices, cloud resources and accounts you do not know you have.",{"slug":58,"name":59,"problem":60},"endpoint-management","Device management (MDM and UEM)","Every company laptop and phone is known, encrypted, locked down and up to date."]
