comparing the hash of the firmware to a list of known good hashes).īut if you’re concerned whether your server is infected with this malware or not, you can use a simple method as below:Īs noted, the malware – in an attempt to maintain persistence and prevent being cleaned – silently blocks the firmware upgrade process. Moreover, the set of real iLO firmware is very small, so taking a whitelist approach is possible and better suited. Mainly because without having an iLO dump tool at hand, it will be impossible to read the firmware and check its hash. While it’s customary to provide hashes as IOCs, we decided that this will not be effective against this malware.

You can only prevent this in the G10 series if a non-default setting is enabled. Even if iLO has been updated to the latest version that does not have any known vulnerabilities, it is still possible to downgrade it to a lower version., which makes infecting fully-patched firmware possible.So, the firmware of these versions is at more risk of being modified and infected by malware. In iLO4 and its earlier versions used on G9 and below servers, there is no Secure-Boot mechanism with an embedded Trusted Root Key in the hardware.Research over the years has revealed several vulnerabilities in HP iLO that have led to patches and architectural changes by the manufacturer.This means that if an intruder has access to a user with administrator/root privileges on the main operating system installed on the server, it can – without needing any further authentication – directly communicate with the iLO, and infect it if it is vulnerable. Accessing and infecting iLO is not only possible through the iLO network port, but also through the system administrator or root access to the main operating system.The iLO admin panel of HP servers is a safe haven for malware which – after infection – cannot be detected or cleaned up by conventional methods.We hope this report will serve as a turning point for attracting more public attention to the security of firmware and creating solutions to protect them. We intend to make these available to the general public in the near future. In addition to this report, we’ve developed some tools to dump iLO firmware and check for infections. Finally, in the last section, we will discuss strategies and solutions for protecting iLO. Then, in the next section, we will analyze the discovered malware and its various modules. Since analyzing this malware requires some knowledge of the HP iLO firmware architecture, we’ll first give a general overview of the HP iLO architecture. As far as we know, this is the first report of the discovery of real-world malware in iLO firmware in the world. This malware has been used by hackers for some time and we have been monitoring its performance. In this report, we analyze a rootkit discovered in-the-wild that hides inside the iLO, cannot be removed by firmware upgrades and can be hidden from the sight for a long time. There are numerous aspects of iLO that make it an ideal utopia for malware and APT groups: Extremely high privileges (above any level of access in the operating system), very low-level access to the hardware, being totally out of the sight of the admins, and security tools, the general lack of knowledge and tools for inspecting iLO and/or protecting it, the persistence it provides for the malware to remain even after changing the operating system, and in particular being always running and never shutting down…

In addition to managing the server hardware, it allows the admin to remotely turn the server on and off, gain access to the server’s console, and even install an operating system on it.

This module has full access to all the firmware, hardware, software, and operating system installed on the server. Integrated Lights-Out), which turns on as soon as the power cable is connected, loading a full-blown proprietary operating system. HP servers provide a management module called iLO (a.k.a.
