Two Year Old Linux Backdoor Found, Microsoft Finds IoT Vulnerabilities - ThreatWire In the latest episode of ThreatWire, hosted by Shannon Morse, critical security issues have emerged, highlighting the vulnerability landscape in both IoT devices and Linux systems. This episode, which aired on May 4, 2021, delivers a comprehensive analysis of two significant threats unveiled by Microsoft and findings from cybersecurity experts regarding a long-standing Linux backdoor. Microsoft has published a report detailing various vulnerabilities impacting a wide range of IoT (Internet of Things) and industrial control devices. These vulnerabilities, termed "bad allocation," could allow attackers to bypass security protocols, leading to system crashes or remote code execution through heap overflows. Over 25 CVEs (Common Vulnerabilities and Exposures) have been identified, prompting urgent patching efforts from affected manufacturers including those utilizing Amazon FreeRTOS and Google Cloud IoT Device SDKs . In addition to IoT concerns, a Linux backdoor dubbed RotaJack has been detected that has remained undetected since 2018. This malware targets 64-bit Linux systems and is capable of exfiltrating data, reporting device details, and managing file functions. The target still lacks a definitive understanding of its core purpose, with researchers noting its similarities to previously identified threats like the Tori botnet . Finally, the episode covers a significant action taken by law enforcement, specifically the FBI's decision to forward millions of email addresses harvested from the Emotet botnet to the "Have I Been Pwned" service. This move aims to alert affected individuals about potential breaches linked to this notorious botnet, previously disbanded by international law enforcement efforts .

What This Means for Users​

As these vulnerabilities—both in IoT devices and Linux systems—can affect everyday users and enterprises alike, it’s crucial to stay informed and proactive:

1. Update Regularly: Ensure that all connected devices are regularly updated with the latest security patches.
2. Monitor Network Traffic: Implement monitoring tools to observe unusual activities within your network, especially if using IoT devices.
3. Awareness of Email Security: Use services like "Have I Been Pwned" to check if personal email addresses were involved in breaches like that of Emotet. With an ever-evolving cybersecurity landscape, understanding these vulnerabilities and maintaining rigorous security practices is paramount. What are your thoughts on these recent developments?
