Intel AMT vulnerability affects Active Management Technology (AMT), Intel Standard Manageability (ISM), and Intel Small Business Technology (SBT) software, versions 6 through 11.6. The flaw was originally discovered by Maksim Malyutin, a member of the Embedi research team, in mid-February, who then responsibly disclosed it to the Intel security team. If exploited, a remote attacker can hijack computers powered by Intel chipset just by sending an empty authentication string.
