5.3 Effectiveness against vulnerabilitiesThe Management Engine is often confused with Intel AMT (Intel Active Management Technology). The Electronic Frontier Foundation has voiced concern about Intel ME and some security researchers have voiced concern that it is a backdoor.Intel's main competitor AMD has incorporated the equivalent AMD Secure Technology (formally called Platform Security Processor) in virtually all of its post-2013 CPUs. This issue can be mitigated with deployment of a hardware device, which is able to disconnect mains power.The Intel ME is an attractive target for hackers, since it has top level access to all devices and completely bypasses the operating system. Go to intel management engine interface right.The Intel Management Engine always runs as long as the motherboard is receiving power, even when the computer is turned off. Keep your fingers well away from any electrical components or moving parts. The latest version of Intel(R) Management Engine Components is 2101., released on.

Design The subsystem primarily consists of proprietary firmware running on a separate microprocessor that performs tasks during boot-up, while the computer is running, and while it is asleep. While AMT can be unprovisioned by the owner, there is no official, documented way to disable the ME. AMT gives device owners remote administration of their computer, such as powering it on or off, and reinstalling the operating system.However, the ME itself is built into all Intel chipsets since 2008, not only those with AMT.

The ME state is stored in a partition of the SPI flash, using the Embedded Flash File System (EFFS). Hardware Starting with MEВ 11, it is based on the Intel Quark x86-based 32-bit CPU and runs the MINIX 3 operating system. Its exact workings are largely undocumented and its code is obfuscated using confidential Huffman tables stored directly in hardware, so the firmware does not contain the information necessary to decode its contents. Intel claims the ME is required to provide full performance.

The ME also communicates with the host via PCI interface. Starting with ME 7.1, the ARC processor could also execute signed Java applets.The ME has its own MAC and IP address for the out-of-band interface, with direct access to the Ethernet controller one portion of the Ethernet traffic is diverted to the ME even before reaching the host's operating system, for what support exists in various Ethernet controllers, exported and made configurable via Management Component Transport Protocol (MCTP). Versions 1.x to 5.x of the ME used the ARCTangent-A4 (32-bit only instructions) whereas versions 6.x to 8.x used the newer ARCompact (mixed 32- and 16-bit instruction set architecture).

On May 1, 2017, Intel confirmed a Remote Elevation of Privilege bug (SA-00075) in its Management Technology. Several weaknesses have been found in the ME. Near Field Communication, a middleware for NFC readers and vendors to access NFC cards and provide secure element access, found in later MEI versions. Intel Platform Trust Technology (PTT), a firmware-based Trusted Platform Module (TPM) Intel Anti-Theft Technology (AT), discontinued in 2015. Communication with the QST firmware subsystem is documented and available through the official software development kit (SDK).

In July 2018 another set of vulnerabilities was disclosed (SA-00112). Unlike SA-00075, this bug is even present if AMT is absent, not provisioned or if the ME was 'disabled' by any of the known unofficial methods. Additional major security flaws in the ME affecting a very large number of computers incorporating ME, Trusted Execution Engine (TXE), and Server Platform Services (SPS) firmware, from Skylake in 2015 to Coffee Lake in 2017, were confirmed by Intel on 20 November 2017 (SA-00086). Several ways to disable the ME without authorization that could allow ME's functions to be sabotaged have been found.

) For the vulnerable Q35 chipset, a keystroke logger ME-based rootkit was demonstrated by Patrick Stewin. (The 'в€’3' designation was chosen because the ME coprocessor works even when the system is in the S3 state, thus it was considered a layer below the System Management Mode rootkits. The ME rootkit could be installed regardless of whether the AMT is present or enabled on the system, as the chipset always contains the ARC ME coprocessor. The exploit worked by remapping the normally protected memory region (top 16В MB of RAM) reserved for the ME. Ring в€’3 rootkit A ringВ в€’3 rootkit was demonstrated by Invisible Things Lab for the Q35 chipset it does not work for the later Q45 chipset as Intel implemented additional protections.

The vulnerability, which was nicknamed 'Silent Bob is Silent' by the researchers who had reported it to Intel, affects numerous laptops, desktops and servers sold by Dell, Fujitsu, Hewlett-Packard (later Hewlett Packard Enterprise and HP Inc.), Intel, Lenovo, and possibly others. Silent Bob is Silent) In May 2017, Intel confirmed that many computers with AMT have had an unpatched critical privilege escalation vulnerability ( CVE-2017-5689). For about 60 euros, Ververis purchased from Go Daddy a certificate that is accepted by the ME firmware and allows remote 'zero touch' provisioning of (possibly unsuspecting) machines, which broadcast their HELLO packets to would-be configuration servers. It also found that the 'zero touch' provisioning mode (ZTC) is still enabled even when the AMT appears to be disabled in BIOS. In particular, it criticized AMT for transmitting unencrypted passwords in the SMB provisioning mode when the IDE redirection and Serial over LAN features are used.

SOL is disabled by default, and must be enabled to exploit this vulnerability. It can be used to install persistent malware (possibly in firmware), and read and modify any data.'вЂ” Tatu YlГ¶nen, ssh.com PLATINUM In June 2017, the PLATINUM cybercrime group became notable for exploiting the serial over LAN (SOL) capabilities of AMT to perform data exfiltration of stolen documents. The vulnerability was described as giving remote attackers:'full control of affected machines, including the ability to read and modify everything. Other reports claimed the bug also affects systems made as long ago as 2008.
