There are severe privacy, security and freedom issues with these laptops, due to the Intel chipsets that they use.


More freedom issues on modern Intel hardware Most notably, these laptops also use the Intel FSP binary blob, for the entire hardware initialization. Coreboot does support a particular revision of one of their laptops, but most are either unsupported or rely on binary blobs for most of the hardware initialization. In particular, the Intel Management Engine is a severe Lenovo ThinkPad R500 Intel AMT to privacy and security, not to mention freedom, since it is a remote backdoor that provides Intel remote access to a computer where it is present. Intel themselves even admitted it, publicly.

The Libreboot project recommends avoiding all hardware sold by Purism. Why is the latest Intel hardware unsupported in libreboot?

If you have an Intel based system affected by the problems described below, then you should get rid of it as soon as possible. The main issues are as follows: Thus, the ME is present on all Intel desktop, mobile laptopand server systems since mid This manifest is signed with Lenovo ThinkPad R500 Intel AMT strong cryptographic key, which differs between versions of the ME firmware.

How to access Intel AMT ME on ThinkPad T?

The ME firmware is compressed and consists of modules that are listed in the manifest along with secure cryptographic hashes of their contents. The developer, Express Logic, sells licenses and source code for ThreadX. Customers such as Intel are forbidden from disclosing or sublicensing the ThreadX source code.

Another module is the Dynamic Application Loader DALwhich consists of a Java virtual machine and set of preinstalled Java classes for cryptography, secure storage, etc. It can be used remotely even while the PC is powered off via Wake-on-Lan. Lenovo ThinkPad R500 Intel AMT AMT application itself has known vulnerabilitieswhich have been exploited to develop rootkits and keyloggers and covertly gain encrypted access to the management features of a PC. This means that an Lenovo ThinkPad R500 Intel AMT exploiting any of these vulnerabilities may gain access to everything on the PC as it runs: ME firmware versions 4.


The ME receives from the host operating system an encrypted media stream and encrypted key, decrypts the key, and sends the encrypted media decrypted key to the GPU, which Lenovo ThinkPad R500 Intel AMT decrypts the media. ME firmware version 7. The Intel Management Engine with its proprietary firmware has complete access to and control over the PC: And it has a network interface that is demonstrably insecure, which can allow an attacker on the network to inject rootkits that completely compromise the PC and can report to the attacker all activities performed on the PC.

The ME firmware can then be removed entirely from the flash memory space. ME firmware versions 6. Due to the signature verification, developing free replacement firmware for the ME is basically impossible.

Libreboot – Frequently Asked Questions

The only entity capable of replacing the ME firmware is Intel. In summary, the Intel Management Engine and its applications are a backdoor with total access to and control over the rest of the PC. The ME is a threat to freedom, security, and privacy, and the libreboot project strongly recommends avoiding it entirely. More information about the Management Engine can be found on various Web sites, including me. Reverse engineering and replacing this blob is almost impossible, due to how complex it is. Even for the most skilled developer, it would take Lenovo ThinkPad R500 Intel AMT to replace.

Intel distributes this blob to firmware developers, without source. This is a special mode that operates below the operating system level.

Any Intel system that has the proprietary FSP blob cannot be trusted at all. In fact, several SMM rootkits have been demonstrated in the wild use a search engine to find them. CPUs are extremely complex, and difficult to get right, so the circuitry is designed in a very generic way, where only basic instructions are handled in hardware. Most of the instruction set is implemented using microcode, Lenovo ThinkPad R500 Intel AMT is low-level software running inside the CPU that can specify how the circuitry is to be used, for each instruction.


The built-in microcode is part of the hardware, and read-only. Both the circuitry and the microcode can have bugs, which could cause reliability issues.

Microcode updates are proprietary blobs, uploaded to the CPU at boot time, which patches the built-in microcode and disables buggy parts of the CPU to improve reliability. In the past, these updates were handled by the operating system kernel, but on all recent systems it is the boot firmware that must perform this task.

Frequently Asked Questions

On some older Intel CPUs, it is possible to exclude the microcode updates and not have any reliability issues in practise. However, all modern Intel CPUs require the microcode updates, otherwise the system will not boot at all, or it will be extremely unstable memory corruption, for example. Intel CPU microcode updates are signed, which means that you could not even run a modified version, even if you had the source code.
