Intel AMT Loophole Allows Hackers to Gain Control of Some PCs in Under a Minute

Researchers have found a loophole in Intel processors that allow an attacker to bypass logins and place backdoors on laptops, allowing adversaries remote access to laptops. Researchers at F-Secure, that first identified the attack strategy, say the loophole can be exploited in less than one minut...

Meltdown and Spectre fallout: patching problems persist

Last week, the disclosure by multiple teams from Graz and Pennsylvania University, Rambus, Data61, Cyberus Technology, and Google Project Zero of vulnerabilities under the aliases Meltdown and Spectre rocked the security world, sending vendors scurrying to create patches, if at all possible, and...

The vulnerabilities of Intel, ARM, and AMD processors stem from the unique workings of the branch prediction module, which allows attackers to exploit the protected information.

The vulnerabilities of Intel, ARM, and AMD processors are related to the characteristics of the branch prediction module’s operation. Exploiting these vulnerabilities allows attackers to gain access to protected memory from a program that does not have the necessary privileges, by creating...

The vulnerability of Intel and ARM processors is caused by a memory access control error during speculative execution of processor instructions, allowing attackers to disclose protected information.

The vulnerabilities of Intel and ARM processors stem from errors in memory access control during speculative execution of processor instructions. Exploiting these vulnerabilities allows attackers to gain access to protected memory from a program that does not have the necessary privileges. This i...
