As a cybersecurity channel, one of the most common comments I receive when discussing malware is, "Just switch to Linux!" This perspective is understandable. If you were using Windows XP and ran a random file from the internet, you'd likely encounter issues, possibly even a blue screen of death. In contrast, such problems were less common with a Linux distribution, making it a safer choice for simple users needing internet access. Most malware, like .exe drive-by downloads, wouldn't even run on Linux.
However, once you delve into cybersecurity, you quickly realize that Linux malware is nearly as prevalent as Windows malware, especially today. Let's start with an example: the Mirai botnet. On a Linux distribution, a quick analysis of a Mirai sample shows HTTP request connections leading to malware command and control activity. Mirai is infamous for targeting not desktop users, but IoT devices—smart refrigerators, televisions, routers, thermostats—all vulnerable to becoming part of a botnet used for massive DDoS attacks.
In previous videos, I've demonstrated ransomware executing on Linux. Malware on Linux is not new, and understanding this is crucial for a broader perspective on cybersecurity. It's also worth noting that Linux isn't immune to vulnerabilities. For instance, Debian Linux and Android are the top two platforms with reported vulnerabilities, while Windows ranks much lower at number ten. This isn't to say Windows isn't vulnerable; many Windows vulnerabilities have been severe. The point is, cybersecurity issues affect all platforms, not just Windows.
A common misconception, especially among everyday users, is that cybersecurity problems stem solely from poor Windows architecture. While many issues do originate there, malware and cybersecurity threats are not confined to computers. Major incidents are often the result of social engineering rather than drive-by downloads.
For example, on Malware Bazaar, Mirai and Agent Tesla are the top malware families. Mirai is primarily distributed on Linux, leading with 911 submissions, many targeting vulnerable routers. Similarly, .elf files, the Linux equivalent of .exe files, are submitted nearly as often as .exe files.
This prevalence is partly because ransomware gangs target large corporations, many of which run Linux servers. For instance, Hive ransomware has both .exe and .elf variants. Once infiltrators gain access, they deploy the necessary malware version based on the platform.
Using platforms like Any.Run, which sponsors this video, we can analyze Linux samples. Any.Run allows you to upload files and watch them execute live in a virtual machine, providing a detailed breakdown of processes, connections, and DNS requests. Their analysis shows that Linux malware can modify file and directory permissions and execute through command interpreters, similar to Windows ransomware.
In conclusion, malware on Linux is a significant issue in 2024. Many security researchers focus exclusively on Linux malware, with numerous conferences and papers dedicated to botnets predominantly infecting Linux systems. If you're interested in Linux malware analysis, consider using Any.Run. They offer various plans suited for independent researchers and corporate users, making it a convenient tool for quick sandbox analysis.
